Olfactory bulb main interneuron periglomerular cellSomaGabaPossibly from other interneurons in the glomerular layer. Spontaneous and electrically driven GABAergic synaptic inputs to PG cells come possibly from other interneurons in the glomerular layer. (Puopolo M and Belluzzi O, 1998326 ) Reversed chloride gradients, demonstrated by cytochemical methods, may be responsible for excitatory GABA effects on selected periglomerular neurons (Siklós L et al, 1995331 ) Voltage-sensitive dye signals recorded from the glomerular layer reflect activity in periglomerular cells and that Cl- efflux through non-GABAA chloride channels contributes to the postsynaptic depolarization of these cells after olfactory nerve stimulation (Senseman DM, 1996330 ). It was shown that stimulation of PG cells results in self-inhibition: release of GABA from an individual PG cell activates GABA(A) receptors on the same neuron (Smith TC and Jahr CE, 2002471 ).
