  text: The medial septal region and the hippocampus are connected reciprocally via
    GABAergic neurons, but the physiological role of this loop is still not well understood.
    In an attempt to reveal the physiological effects of the hippocamposeptal GABAergic
    projection, we cross-correlated hippocampal sharp wave (SPW) ripples or theta
    activity and extracellular units recorded in the medial septum and diagonal band
    of Broca (MSDB) in freely moving rats. The majority of single MSDB cells (60%)
    were significantly suppressed during SPWs. Most cells inhibited during SPW (80%)
    fired rhythmically and phase-locked to the negative peak of the CA1 pyramidal
    layer theta waves. Because both SPW and the negative peak of local theta waves
    correspond to the maximum discharge probability of CA1 pyramidal cells and interneuron
    classes, the findings indicate that the activity of medial septal neurons can
    be negatively (during SPW) or positively (during theta waves) correlated with
    the activity of hippocampal interneurons. We hypothesize that the functional coupling
    between medial septal neurons and hippocampal interneurons varies in a state-dependent
    manner.

  text: Information in neuronal networks may be represented by the spatiotemporal
    patterns of spikes. Here we examined the temporal coordination of pyramidal cell
    spikes in the rat hippocampus during slow-wave sleep. In addition, rats were trained
    to run in a defined position in space (running wheel) to activate a selected group
    of pyramidal cells. A template-matching method and a joint probability map method
    were used for sequence search. Repeating spike sequences in excess of chance occurrence
    were examined by comparing the number of repeating sequences in the original spike
    trains and in surrogate trains after Monte Carlo shuffling of the spikes. Four
    different shuffling procedures were used to control for the population dynamics
    of hippocampal neurons. Repeating spike sequences in the recorded cell assemblies
    were present in both the awake and sleeping animal in excess of what might be
    predicted by random variations. Spike sequences observed during wheel running
    were “replayed” at a faster timescale during single sharp-wave bursts of slow-wave
    sleep. We hypothesize that the endogenously expressed spike sequences during sleep
    reflect reactivation of the circuitry modified by previous experience. Reactivation
    of acquired sequences may serve to consolidate information.

  text: We examined whether excitation and inhibition are balanced in hippocampal
    cortical networks. Extracellular field and single-unit activity were recorded
    by multiple tetrodes and multisite silicon probes to reveal the timing of the
    activity of hippocampal CAI pyramidal cells and classes of interneurons during
    theta waves and sharp wave burst (SPW)-associated field ripples. The somatic and
    dendritic inhibition of pyramidal cells was deduced from the activity of interneurons
    in the pyramidal layer [int(p)] and in the alveus and st. oriens [int(a/o)], respectively.
    int(p) and int(a/o) discharged an average of 60 and 20 degrees before the population
    discharge of pyramidal cells during the theta cycle, respectively. SPW ripples
    were associated with a 2.5-fold net increase of excitation. The discharge frequency
    of int(a/o) increased, decreased (”anti-SPW” cells), or did not change (”SPW-independent”
    cells) during SPW suggesting that not all interneurons are innervated by pyramidal
    cells. Int(p) either fired together with (unimodal cells) or both before and after
    (bimodal cells) the pyramidal cell burst. During fast-ripple oscillation, the
    activity of interneurons in both the int(p) and int(a/o) groups lagged the maximum
    discharge probability of pyramidal neurons by 1-2 msec. Network state changes,
    as reflected by field activity, covaried with changes in the spike train dynamics
    of single cells and their interactions. Summed activity of parallel-recorded interneurons,
    but not of pyramidal cells, reliably predicted theta cycles, whereas the reverse
    was true for the ripple cycles of SPWs. We suggest that network-driven excitability
    changes provide temporal windows of opportunity for single pyramidal cells to
    suppress, enable, or facilitate selective synaptic inputs.

  text: We have examined gating and pharmacological characteristics of somatic K+
    channels in fast-spiking interneurons and regularly spiking principal neurons
    of hippocampal slices. In nucleated patches isolated from basket cells of the
    dentate gyrus, a fast delayed rectifier K+ current component that was highly sensitive
    to tetraethylammonium (TEA) and 4-aminopyridine (4- AP) (half-maximal inhibitory
    concentrations &lt;0.1 mM) predominated, contributing an average of 58% to the
    total K+ current in these cells. By contrast, in pyramidal neurons of the CA1
    region a rapidly inactivating A- type K+ current component that was TEA-resistant
    prevailed, contributing 61% to the total K+ current. Both types of neurons also
    showed small amounts of the K+ current component mainly found in the other type
    of neuron and, in addition, a slow delayed rectifier K+ current component with
    intermediate properties (sow inactivation, intermediate sensitivity to TEA). Single-cell
    RT-PCR analysis of mRNA revealed that Kv3 (Kv3.1, Kv3.2) subunit transcripts were
    expressed in almost all (89%) of the interneurons but only in 17% of the pyramidal
    neurons. In contrast, Kv4 (Kv4.2, Kv4.3) subunit mRNAs were present in 87% of
    pyramidal neurons but only in 55% of interneurons. Selective block of fast delayed
    rectifier K+ channels, presumably assembled from Kv3 subunits, by 4-AP reduced
    substantially the action potential frequency in interneurons. These results indicate
    that the differential expression of Kv3 and Kv4 subunits shapes the action potential
    phenotypes of principal neurons and interneurons in the cortex.

  text: 'Neurotransmission in the hippocampus is modulated variously through presynaptic
    metabotropic glutamate receptors (mGluRs). To establish the precise localization
    of presynaptic mGluRs in the rat hippocampus, we used subtype-specific antibodies
    for eight mGluRs (mGluR1-mGluR8) for immunohistochemistry combined with lesioning
    of the three major hippocampal pathways: the perforant path, mossy fiber, and
    Schaffer collateral. Immunoreactivity for group II (mGluR2) and group III (mGluR4a,
    mGluR7a, mGluR7b, and mGluR8) mGluRs was predominantly localized to presynaptic
    elements, whereas that for group I mGluRs (mGluR1 and mGluR5) was localized to
    postsynaptic elements. The medial perforant path was strongly immunoreactive for
    mGluR2 and mGluR7a throughout the hippocampus, and the lateral perforant path
    was prominently immunoreactive for mGluR8 in the dentate gyrus and CA3 area. The
    messy fiber was labeled for mGluR2, mGluR7a, and mGluR7b, whereas the Schaffer
    collateral was labeled only for mGluR7a. Electron microscopy further revealed
    the spatial segregation of group II and group III mGluRs within presynaptic elements.
    Immunolabeling for the group III receptors was predominantly observed in presynaptic
    active zones of asymmetrical and symmetrical synapses, whereas that for the group
    II receptor (mGluR2) was found in preterminal rather than terminal portions of
    axons. Target cell-specific segregation of receptors, first reported for mGluR7a
    (Shigemoto et al., 1996), was also apparent for the other group III mGluRs, suggesting
    that transmitter release is differentially regulated by 2-amino- 4-phosphonobutyrate-sensitive
    mGluRs in individual synapses on single axons according to the identity of postsynaptic
    neurons.'

  text: AMPA- and NMDA-type glutamate receptors (AMPARs and NMDARs) mediate excitatory
    synoptic transmission in the basal ganglia and may contribute to excitotoxic injury.
    We investigated the functional properties of AMPARs and NMDARs expressed by six
    main types of basal ganglia neurons in acute rat brain slices (principal neurons
    and cholinergic interneurons of striatum, GABAergic and dopaminergic neurons of
    substantia nigra, globus pallidus neurons, and subthalamic nucleus neurons) using
    fast application of glutamate to nucleated and outside-out membrane patches, AMPARs
    in different types of basal ganglia neurons were functionally distinct. Those
    expressed in striatal principal neurons exhibited the slowest gating (desensitization
    time constant τ = 11.5 msec, 1 mM glutamate, 22°C), whereas those in striatal
    cholinergic interneurons showed the fastest gating (desensitization time constant
    τ = 3.6 msec). The lowest Ca2+ permeability of AMPARs was observed in nigral dopaminergic
    neurons (P(CA)/P(NA) = 0.10), whereas the highest Ca2+ permeability was found
    in subthalamic nucleus neurons (P(Ca)/P(Na) = 1.17). NMDARs of different types
    of basal ganglia neurons were less variable in their functional properties; those
    expressed in nigral dopaminergic neurons exhibited the slowest gating (deactivation
    time constant of predominant fast component τ1 150 msec, 100 μM glutamate), and
    those of globus pallidus neurons showed the fastest gating (τ1 = 67 msec). The
    Mg2+ block of NMDARs was similar; the average chord conductance ratio g(+60mv)/g(+40mV)
    was 0.18-0.22 in 100 μM external Mg2+. Hence, AMPARs expressed in different types
    of basal ganglia neurons are markedly diverse, whereas NMDARs are less variable
    in functional properties that are relevant for excitatory synoptic transmission
    and neuronal vulnerability.

  text: 'The main excitatory pathway of the hippocampal formation is controlled by
    a network of morphologically distinct populations of GABAergic interneurons. Here
    we describe a novel type of GABAergic interneuron located in the outer molecular
    layer (OML) of the rat dentate gyrus with a long- range forward projection from
    the dentate gyrus to the subiculum across the hippocampal fissure, OML interneurons
    were recorded in hippocampal slices by using the whole-cell patch-clamp configuration.
    During recording, cells were filled with biocytin for subsequent light and electron
    microscopic analysis. Neurons projecting to the subiculum were distributed throughout
    the entire OML. They had round or ovoid somata and a multipolar dendritic morphology.
    Two axonal domains could be distinguished: an extensive, tangential distribution
    within the OML and a long-range vertical and tangential projection to layer 1
    and stratum pyramidale of the subiculum. Symmetric synaptic contacts were established
    by these interneurons on dendritic shafts in the OML and subiculum. OML interneurons
    were characterized physiologically by short action potential duration and marked
    afterhyperpolarization that followed the spike. On sustained current injection,
    they generated high- frequency (up to 130 Hz, 34°C) trains of action potentials
    with only little adaptation. In situ hybridization and single-call RT-PCR analysis
    for GAD67 mRNA confirmed the GABAergic nature of OML interneurons. GABAergic interneurons
    in the OML projecting to the subiculum connect the input and output regions of
    the hippocampus. Hence, they could mediate long-range feed- forward inhibition
    and may participate in an oscillating cross-regional interneuron network that
    may synchronize the activity of spatially distributed principal neurons in the
    dentate gyrus and the subiculum.'

  text: Tight-seal whole-cell recordings were made from cleaned somata of CA3 pyramidal
    cells deep in hippocampal slices from 19–21-d-old rats. The cells were filled
    with biocytin, and their voltage responses to short current pulses were recorded.
    After washout of initial sag, responses scaled linearly with injected current
    and were stable over time. The dendritic and axonal arbors of four cells were
    reconstructed and measured using light microscopy. Dendritic spines and axonal
    boutons were counted and the additional membrane area was incorporated into the
    relevant segments. The morphology of each neuron was converted into a detailed
    branching cable model by assuming values for specific membrane capacitance Cm
    and resistance Rm, and cytoplasmic resistivity Ri. These parameters were optimized
    for each cell by directly matching the model's response to that of the real cell
    by means of a modified weighted least-squares fitting procedure. By comparing
    the deviations between model and experimental responses to control noise recordings,
    approximate 95% confidence intervals were established for each parameter. If a
    somatic shunt was allowed, a wide range of possible Rm values produced acceptable
    fits. With zero shunt, Cm was 0.7–0.8 microFcm-2, Ri was 170–340 omega cm, and
    Rm ranged between 120 and 200 k omega cm2. The electrotonic lengths of the basal
    and oblique dendrites were 0.2–0.3 space constants, and those of the apical tufts
    were 0.4–0.7 space constants. The steady-state electrical geometry of these cells
    was therefore compact; average dendritic tip/soma relative synaptic efficacies
    were &gt; 93% for the basal and oblique dendrites, and &gt; 81% for the tufts.
    With fast transient synaptic inputs, however, the models produced a wide range
    of postsynaptic potential shapes and marked filtering of voltage-clamp currents.

  text: 'The metabotropic glutamate receptors are coupled to intracellular signal
    transduction via G-proteins and consist of a family of at least five different
    subtypes, termed mGluR1-mGluR5. We studied the signal transduction mechanism and
    pharmacological characteristics of the rat mGluR3 and mGluR4 subtypes in Chinese
    hamster ovary cells permanently expressing the cloned receptors. Both mGluR3 and
    mGluR4 inhibit the forskolin-stimulated accumulation of intracellular cAMP formation
    in response to agonist interaction. Consistent with the high degree of sequence
    similarity to mGluR2, mGluR3 closely resembles mGluR2 in its agonist selectivity;
    the potency rank order of agonists is L-glutamate &gt; trans-1-aminocyclopentane-
    1,3-dicarboxylate &gt; ibotenate &gt; quisqualate. mGluR4 is totally different
    in its agonist specificity from any other member of the metabotropic receptors.
    This receptor potently reacts with L-2-amino-4-phosphonobutyrate(L-AP4) in a stereo-selective
    manner and moderately responds to L-serine-O-phosphate. mGluR4 thus corresponds
    well to the putative L-AP4 receptor characterized from brain preparations. Blot
    and in situ hybridization analyses indicated that both mRNAs are widely distributed
    in the rat brain. mGluR3 mRNA is highly expressed in neuronal cells of the cerebral
    cortex and the caudate- putamen, and in granule cells of the hippocampal dentate
    gyrus. The expression pattern of mGluR4 mRNA is more restricted, and this expression
    is prominent in the cerebellum, olfactory bulb, and thalamus. Furthermore, the
    mGluR3 mRNA, unlike the other mRNAs for the metabotropic receptors, is highly
    expressed in glial cells throughout the brain regions. The metabotropic glutamate
    receptor subtypes can thus be classified into three subgroups according to the
    similarity in their amino acid sequences, signal transduction, and agonist selectivity:
    mGluR1/mGluR5, mGluR2/mGluR3, and mGluR4. The mRNAs for the individual receptor
    subtypes, however, show overlapping but distinct patterns of expression in the
    rat CNS.'
