The postsynaptic density
The postsynaptic density (PSD) is a protein dense specialization attached to the postsynaptic membrane. PSDs were originally identified by electron microscopy as an electron-dense region at the membrane of a postsynaptic neuron. The PSD is in close apposition to the presynaptic active zone and ensures that … Visa mer The structure and composition of the PSD have been the focus of numerous molecular studies of synaptic plasticity, a cellular model of learning and memory. PSDs are sized on the order of 250 to 500 nanometres in … Visa mer The PSD has been proposed to concentrate and organize neurotransmitter receptors in the synaptic cleft. The PSD also … Visa mer • Postsynaptic Density- Cell Centered Database Visa mer Webbb. Inside the presynaptic neuron are synaptic vesicles, which fuse with the membrane in the active zone. c. Inside the presynaptic neuron are synaptic vesicles, which fuse with the membrane in the postsynaptic density. d. A gap junction connects the two neurons via connexons that span the pre- and postsynaptic membranes. e. None of the above

The equilibrium potential of chloride is -65 mV, so if the neuron is at rest at -60 mV, when chloride channels open, the electrochemical gradients drive chloride to flow into the cell.
