Compensation of a sensory deficit inflicted upon newborn and adult animals. A behavioural study

Somatosensory deprivation (bilateral vibrissa clipping) was performed on newborn (P1) and adult (P80) rats and, on 10 successive days starting on day 81, the effect of sensory deprivation was tested in a rectangular maze versus controls. The maze performance (the time to reach the goal-box with food...

Description
Summary:	Somatosensory deprivation (bilateral vibrissa clipping) was performed on newborn (P1) and adult (P80) rats and, on 10 successive days starting on day 81, the effect of sensory deprivation was tested in a rectangular maze versus controls. The maze performance (the time to reach the goal-box with food reward) of the P80 animals was significantly poorer than that of P1 animals. The tests repeatedly demonstrated, however, that the maze performance achieved by the P1 animals was better than that of the controls. This behavioural study clearly revealed that early sensory deprivation induced (probably cross-modal) compensatory changes in other sensory systems.
