Fig. 1. Alterations in conditional positive and inhibitory reflexes following exposure 

 to 7 doses of 50 r each. The first graph gives control data: irradiation was administered 

 as shown by the word written vertically, and the time scale is in days following each 

 day of administration. This animal is considered strong and well balanced, and the 

 upset of strength relations and frequent increase in the motor-feeding reaction is noted 

 particularly. Redrawn from Khozak (1958).
