Habituation in the crab Chasmagnathus granulatus: effect of morphine and naloxone

The escape response decrement shown by the crab Chasmagnathus granulatus as a consequence of repeated shadow presentation, meets five of the seven tested parametric criteria of habituation. Results concerning stimulus generalization and dishabituation strongly suggest that neither motor fatigue nor...
