EXPLORATION OF NEURAL CODING IN RAT'S AGRANULAR MEDIAL AND AGRANULAR LATERAL CORTICES DURING LEARNING OF A DIRECTIONAL CHOICE TASK


Abstract Animals learn to choose a proper action among alternatives according to the circumstance. Through trial-and-error, animals improve their odds by making correct association between their behavioral choices and external stimuli. While there has been an extensive literature on the theory of learning, it is still unclear how individual neurons and a neural network adapt as learning progresses. In this dissertation, single units in the medial and lateral agranular (AGm and AGl) cortices were recorded as rats learned a directional choice task. The task required the rat to make a left/right side lever press if a light cue appeared on the left/right side of the interface panel. Behavior analysis showed that rat's movement parameters during perf... (more)
