title: [Organization of receptive fields of tonic and phasic neurons in cat pulvinar].
abstract: The receptive fields of 26% out of 163 pulvinar neurons were characterized by phasic pattern of responses whereas those of 15% of neurons had tonic characteristics. The receptive fields of 59% of neurons consisted both of tonic and phasic subfields. These findings suggested convergence of two types of afferents on the same pulvinar neuron. The cell population receiving pure tonic or pure phasic afferents constituted 41% of all the neurons under study. The measurement of latencies of responses to the stationary flashing spot revealed that phasic responses had a shorter latency than tonic and mixed responses.
