The comparison was made of amplitudes of the postsynaptic potential evoked in AP cells by the stimulation of T, P and N cells. The results showed that for each type of T, P and N cell the contralateral member of the pair evoked larger synaptic potentials in the AP cell that did its ipsilateral homologue and the T, P and N cell with a dorsally situated receptive field produced a larger synaptic input on the AP cell that its counterpart with a ventrally situated receptive field.
