Responses of medullary dorsal horn neurons to corneal stimulation by CO(2) pulses in the rat.

abstract：:Retinal ganglion cells (RGC) transmit visual signals to thalamocortical relay neurons in the lateral geniculate nucleus via retinogeniculate synapses. Relay neuron spike patterns do not simply reflect those of RGCs, but the mechanisms controlling this transformation are not well understood. We therefore examined synap...
