We investigated the induction mechanisms of associative LTD in CA1 pyramidal neurons of the hippocampus using whole-cell patch-clamp recordings and Ca2+ imaging in acute brain slices. Asynchronous pairing of postsynaptic action potentials with EPSPs evoked with a delay of 20 msec induced a robust, long-lasting depression of the EPSP amplitude to 43%. Unlike LTD induced by low-frequency stimulation, associative LTD was resistant to the application of D-AP-5, indicating that it is independent of NMDA receptors. In contrast, associative LTD was inhibited by (S)-α-methyl-4-carboxyphenyl-glycine, indicating the involvement of metabotropic glutamate receptors. Furthermore, associative LTD is dependent on the activation of voltage-gated Ca2+ channels by postsynaptic action potentials. Both nifedipine, an L-type Ca2+ channel antagonist, and ω-conotoxin GVIA, a selective N-type channel blocker, abolished the induction of associative LTD. 8-hydroxy-2-dipropylaminotetralin (OH-DPAT), a 5-HT(1A) receptor agonist, inhibited postsynaptic Ca2+ influx through N-type Ca2+ channels, without affecting presynaptic transmitter release. OH-DPAT also inhibited the induction of associative LTD, suggesting that the involvement of N-type channels makes synaptic plasticity accessible to modulation by neurotransmitters. Thus, the modulation of N-type Ca2+ channels provides a gain control for synaptic depression in hippocampal pyramidal neurons."}],"author":[{"full_name":"Normann, Claus","first_name":"Claus","last_name":"Normann"},{"first_name":"Diana","full_name":"Peckys, Diana","last_name":"Peckys"},{"last_name":"Schulze","first_name":"Christian","full_name":"Schulze, Christian"},{"first_name":"Jörg","full_name":"Walden, Jörg","last_name":"Walden"},{"orcid":"0000-0001-5001-4804","first_name":"Peter M","full_name":"Jonas, Peter M","id":"353C1B58-F248-11E8-B48F-1D18A9856A87","last_name":"Jonas"},{"full_name":"Bischofberger, Joseph","first_name":"Joseph","last_name":"Bischofberger"}],"doi":"10.1523/JNEUROSCI.20-22-08290.2000","_id":"3490","publication_identifier":{"issn":["0270-6474"]},"volume":20,"date_updated":"2023-05-03T08:02:52Z","type":"journal_article","extern":"1","date_published":"2000-11-15T00:00:00Z","year":"2000","article_type":"original","publisher":"Society for Neuroscience","day":"15","pmid":1,"issue":"22","oa_version":"Published Version","main_file_link":[{"open_access":"1","url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6773198/"}],"title":"Associative long-term depression in the hippocampus is dependent on postsynaptic N-type Ca(2+) channels","quality_controlled":"1","intvolume":"        20","language":[{"iso":"eng"}],"publist_id":"2897"}
