WebCaN regulates synaptic transmission in part through the AMPA receptor. Most of the fast synaptic transmission at excitatory synapses in the brain is mediated by the glutamatergic AMPA-(α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid) receptor (AMPA-R) (Collingridge et al. 1992). In the adult brain, AMPA-Rs are usually composed of ... Webthe presence of fast learning.
