Olfactory cortex anterior interneuron deep layerAxon terminalGabaonto pyramidal neuronInhibition of deep neurons (pyramidal and multipolar) by (presumed?) deep layer interneurons involves a fast Chloride and a slow potassium-mediated IPSP (Tseng GF and Haberly LB, 1989350 ). Different GABAergic receptors are localized to specific layers, and may mediate feedforward and feedback inhibitions (Princivalle A et al, 2000349 ). Cholinergic agonist carbachol caused a significant suppression of inhibitory postsynaptic potentials (IPSPs) in the pyramidal neurons that were induced by stimulation of layer Ib, with a weaker effect on IPSPs induced by stimulation of layer Ia (Patil MM and Hasselmo ME, 1999341 ). Dendritic GABAA-mediated IPSPs act largely independent of somatic IPSPs and may regulate facilitation of MNDA-mediated respnses (Kanter ED et al, 1996356 ).
