The advanced display of behavioral reactions in sensory deprived rat pups

Bilateral section of nervus medianus was made in Wistar rat pups on 13, 14, 15 or 16-th days of life. Developmental analysis of motor abilities, locomotor and exploration activities during 10-30 days of life revealed three groups of facts. 1. Partial deafferentation of forelimbs don't influence...

Description
Summary:	Bilateral section of nervus medianus was made in Wistar rat pups on 13, 14, 15 or 16-th days of life. Developmental analysis of motor abilities, locomotor and exploration activities during 10-30 days of life revealed three groups of facts. 1. Partial deafferentation of forelimbs don't influence on some types of behavior. 2. Some motor abilities hindered in rat pups with section of nervus medianus. 3. Partial deafferentation of forelimb gives rise to the faster appearance of the new types of behavior. The developmental analysis allowed to suggest that faster appearance of certain behavior reactions after deafferentation of the forelimbs is a result of actualization of latent sensory inputs including in the organization of these types of behavior but it is not connected with changing of velocity of morphological maturation.
