Optical recording of neuronal activity in an invertebrate central nervous system: simultaneous monitoring of several neurons.

abstract：:It is well established that patterns of sensory input can affect neuroplastic changes during early development. The scope and consequences of experience-dependent plasticity in the adult are less well understood. We studied the possibility that repeated exposure to trains of stroboscopic stimuli could induce a sensiti...
