Sensory input to cerebellocerebral relay neurons in the cat thalamus.
Intracellular recording techniques were used to study the synaptic responses of feline ventrolateral neurons to dorsal column, spinothalamic and sensory cortex stimulation. More than 75% of the cells responded with short- and long-latency excitatory or inhibitory postsynaptic potentials to the one or/and other stimulation sites. These findings indicate that a considerable amount of somatosensory integration in the cerebellocerebral circuit occurs in the thalamic relay neurons.
