“…In 2-9 months after removal of a single digit, neurons throughout its entire cortical representation region were now responsive to the adjacent digits and skin surfaces of the palm (Merzenich et al, 1984). Auditory deprivation also causes a loss of sound representation (Reale, Brugge, & Chan, 1987) and a decrease in synapse number (Perier, Buyse, Lechat, & Stenuit, 1986) in the cortex. In developing rats, restriction of movement results in poorly developed Purkinje neurons in the cerebullum (Pascual, Hervias, Toha, Valero, & Figueroa, 1998).…”
