Figure 3 The time in the center zone (each group is of 6 animals, under the 8 hr noise/day action). Thus, after 7,30 and 60 days of noise action the rats of the 2nd group spent 67,7%, 35,8%, 32,2% time in the center zone compared with the 1st group (in which the activity was considered to be as 100%), the rats of the 3rd group spent 79%, 56,6%, 124,8%, and the rats of the 4th group spent 71,4%, 63,2%, 150,3%, respectively
