Habenular lesions and avoidance learning deficits in albino rats
Albino rats were given either habenular lesions or control operations and evaluated postsurgically during one-way active avoidance and passive avoidance training. Rats with habenular lesions, particularly thos...

Odor stimuli, training procedures, and performance in a T-maze
This study demonstrates that rats can use odor cues to learn a T-maze discrimination task, thus supporting the findings of a previous study. Furthermore, only a very small quantity of dried food (45 mg) was ne...

Odor cues in a maze discrimination
Rats were found capable of making the choice in a T-maze using the odor from only one 45-mg Noyes food pellet as a discriminative stimulus. This finding points to the need for controlling odor stimuli in the t...

Reinforcing properties of odors for the albino rat
Food deprived and satiated rats were tested in a free operant situation to evaluate the behavior directing properties of odors that were either familiar and significant (food) or novel (amyl acetate). Both odo...
