Popis:	Postsynaptic inhibition in the general cortex of the turtle forebrain was investigated by recording unit activity intracellularly. Depending on the type of IPSPs recorded in response to electrical stimulation of the contralateral optic nerve and cortical surface the neurons were subdivided into three groups: 1) with long direct IPSPs, 2) with long and short direct, and also recurrent IPSPs, 3) with short direct and recurrent IPSPs. It is concluded that inhibitory pathways of the short direct and recurrent IPSPs have a common final component, a stellate interneuron. Compared with the recurrent collaterals of the principal neurons, the direct afferents make contact with more distal portions of the dendrites of this cell. Synapses formed on dendrites of the principal neurons by axons of the stellate cells are nearer to the soma than synapses responsible for generation of the long direct IPSP.
