Full text available as:



Whole-cell recordings from rat lateral amygdala (LA) revealed two populations of principal neurons, that have similar pyramid-like morphologies but differing in firing pattern: late-spiking (LS, 66%) and regular-spiking (RS, 34%). The presence of large numbers of LS neurons arguably supports recent suggestions that the LA should be considered to be a functional extension of perirhinal cortex.
