The postsynaptic density

WebbAbstract Text. Fast glutamatergic synaptic transmission is based on a precise and complex molecular organization which requires the control of the number of AMPA-type glutamate receptors (AMPARs) at the postsynaptic sites of glutamatergic synapses on dendritic spines. The number of AMPARs varies as a function of pre- and postsynaptic activation ... Webb20 aug. 2024 · Building 35, Room 2C-903 35 Convent Drive Bethesda, MD 20892-3704. 301-496-3800.
