Perisaccadic mislocalization of visual targets by head-free gaze shifts: visual or motor?

abstract：:1. Excitatory synaptic transmission in mono- and polysynaptic pathways between dorsal root afferents and alpha-motoneurons was studied in the spinal cord preparation of the neonatal rat isolated in vitro, using sharp-electrode intracellular recordings. 2. The duration of monosynaptic excitatory postsynaptic potentials...
