Behavioral plasticity in the sensitive plant, Mimosa.

The leaves of the sensitive plant Mimosa can adapt their closing response to electrical and mechanical stimulation so that they reopen to repeated stimulation. The more intense the stimuli and the longer the intertrial interval, the longer it takes to adapt. Leaves adapted to the effects of mechanical stimulation can still respond by closing to electrical stimulation and vice versa. The physiology of this phenomenon is discussed and compared to animals.
