The auditory stimulation of 600 cps at 99-103 db was presented chronically (one hour a day for six weeks) and acutely (two hours only). Each animal was injected intraperitoneally 1.87 mc of radioleucine in two doses (1.00 mc and 0.87 mc) with an interval of 30 minutes. After the second injection 30 minutes were allowed, thus permitting a total of 60 minutes for exchange of the radiochemical. Animals from the surgical, chronic stimulation and control groups rested during the exchange period, whereas animals from the acute stimulation group were subjected to the intense auditory stimulation [TRUNCATED] / 2031-01-01
