Abstract

The piriform cortex (PCx) is the main projection area of the olfactory bulb. It further receives afferents from neurons located in the horizontal limb of the diagonal band (HDB) and the magnocellular preoptic nucleus (MCPO) of the basal forebrain. Using an optical recording technique, we examined the influence of electrical stimulation of the HDB-MCPO complex upon the PCxreactivity to electrical stimulation of the olfactory bulb. We observed aninhibitory modulation which was stronger on the intrinsic activity than onthe afferent one. This effect was not homogeneously distributed within thewhole PCx. The neurotransmitter involved and its synaptic target remain tobe determined. The present findings are discussed in view of anatomical and functional data. (C) 1999 Elsevier Science B.V.
