Morphology

prestimulus = stimulus (transparent) = pre + stimulus

Adding 'pre-' to 'stimulus' straightforwardly gives the meaning 'before the stimulus' in an experimental context.

Etymology

Prestimulus combines pre- meaning 'before' and stimulus meaning 'something that causes a response', and you see the same root in stimulate. So prestimulus (adjective) describes activity or signals that happen just before a stimulus is given.
