[Excitatory effects of 2 peptides on rat cortical neurons: laminar distribution and correlation with the effect of acetylcholine].

The most frequent effect observed following iontophoretic application of cholecystokinin or vasoactive intestinal polypeptide on Rat SI cortical neurons was an excitation. Most of the peptide-sensitive neurons were located in infragranular layers of the cortex. In most instances these neurons could also be excited by acetylcholine. These results suggest… CONTINUE READING
