Interhemispheric pathways in simple reaction time to lateralized light flash. 1982

A D Milner, and C R Lines

In two experiments, simple reaction time to left-field or right-field stimulation was measured as a function of light intensity. The response made on each trial in Experiment 1 was a finger movement, and in Experiment 2 a spoken word. In Experiment 1, the advantage of "uncrossed" over "crossed" reaction times remained invariant across intensities. In Experiment 2, however, the advantage of right over left visual-field stimuli in eliciting a vocal reaction varied inversely with intensity. It is suggested that the use of vocal reactions may permit an estimation of a visual commissural transmission time.

D009435 Synaptic Transmission The communication from a NEURON to a target (neuron, muscle, or secretory cell) across a SYNAPSE. In chemical synaptic transmission, the presynaptic neuron releases a NEUROTRANSMITTER that diffuses across the synaptic cleft and binds to specific synaptic receptors, activating them. The activated receptors modulate specific ion channels and/or second-messenger systems in the postsynaptic cell. In electrical synaptic transmission, electrical signals are communicated as an ionic current flow across ELECTRICAL SYNAPSES.
