  text: In vitro work revealed that excitatory synaptic inputs to hippocampal inhibitory
    interneurons could undergo Hebbian, associative, or non-associative plasticity.
    Both behavioral and learning-dependent reorganization of these connections has
    also been demonstrated by measuring spike transmission probabilities in pyramidal
    cell-interneuron spike cross-correlations that indicate monosynaptic connections.
    Here we investigated the activity-dependent modification of these connections
    during exploratory behavior in rats by optogenetically inhibiting pyramidal cell
    and interneuron subpopulations. Light application and associated firing alteration
    of pyramidal and interneuron populations led to lasting changes in pyramidal-interneuron
    connection weights as indicated by spike transmission changes. Spike transmission
    alterations were predicted by the light-mediated changes in the number of pre-
    and postsynaptic spike pairing events and by firing rate changes of interneurons
    but not pyramidal cells. This work demonstrates the presence of activity-dependent
    associative and non-associative reorganization of pyramidal-interneuron connections
    triggered by the optogenetic modification of the firing rate and spike synchrony
    of cells.

  text: The hippocampus is thought to initiate systems-wide mnemonic processes through
    the reactivation of previously acquired spatial and episodic memory traces, which
    can recruit the entorhinal cortex as a first stage of memory redistribution to
    other brain areas. Hippocampal reactivation occurs during sharp wave-ripples,
    in which synchronous network firing encodes sequences of places.We investigated
    the coordination of this replay by recording assembly activity simultaneously
    in the CA1 region of the hippocampus and superficial layers of the medial entorhinal
    cortex. We found that entorhinal cell assemblies can replay trajectories independently
    of the hippocampus and sharp wave-ripples. This suggests that the hippocampus
    is not the sole initiator of spatial and episodic memory trace reactivation. Memory
    systems involved in these processes may include nonhierarchical, parallel components.

  text: Hippocampal neurons encode a cognitive map of space. These maps are thought
    to be updated during learning and in response to changes in the environment through
    activity-dependent synaptic plasticity. Here we examine how changes in activity
    influence spatial coding in rats using halorhodopsin-mediated, spatially selective
    optogenetic silencing. Halorhoposin stimulation leads to light-induced suppression
    in many place cells and interneurons; some place cells increase their firing through
    disinhibition, whereas some show no effect. We find that place fields of the unaffected
    subpopulation remain stable. On the other hand, place fields of suppressed place
    cells were unstable, showing remapping across sessions before and after optogenetic
    inhibition. Disinhibited place cells had stable maps but sustained an elevated
    firing rate. These findings suggest that place representation in the hippocampus
    is constantly governed by activity-dependent processes, and that disinhibition
    may provide a mechanism for rate remapping.

  text: During hippocampal sharp wave/ripple (SWR) events, previously occurring, sensory
    inputdriven neuronal firing patterns are replayed. Such replay is thought to be
    important for plasticity- related processes and consolidation of memory traces.
    It has previously been shown that the electrical stimulation-induced disruption
    of SWR events interferes with learning in rodents in different experimental paradigms.
    On the other hand, the cognitive map theory posits that the plastic changes of
    the firing of hippocampal place cells constitute the electrophysiological counterpart
    of the spatial learning, observable at the behavioral level. Therefore, we tested
    whether intact SWR events occurring during the sleep/rest session after the first
    exploration of a novel environment are needed for the stabilization of the CA1
    code, which process requires plasticity. We found that the newly-formed representation
    in the CA1 has the same level of stability with optogenetic SWR blockade as with
    a control manipulation that delivered the same amount of light into the brain.
    Therefore our results suggest that at least in the case of passive exploratory
    behavior, SWR-related plasticity is dispensable for the stability of CA1 ensembles.

  text: At synapses formed between dissociated neurons, about half of all synaptic
    vesicles are refractory to evoked release, forming the so-called &quot;resting
    pool.&quot; Here, we use optical measurements of vesicular pH to study developmental
    changes in pool partitioning and vesicle cycling in cultured hippocampal slices.
    Two-photon imaging of a genetically encoded two-color release sensor (ratio-sypHy)
    allowed us to perform calibrated measurements at individual Schaffer collateral
    boutons. Mature boutons released a large fraction of their vesicles during simulated
    place field activity, and vesicle retrieval rates were 7-fold higher compared
    to immature boutons. Saturating stimulation mobilized essentially all vesicles
    at mature synapses. Resting pool formation and a concomitant reduction in evoked
    release was induced by chronic depolarization but not by acute inhibition of the
    protein phosphatase calcineurin. We conclude that synapses in CA1 undergo a prominent
    refinement of vesicle use during early postnatal development that is not recapitulated
    in dissociated neuronal culture.
