Table 1. Effect of lactic acid on response latencies in 5CTV.

Latencies (sec, mean and S.D.) from presentation of the visual cue until a correct response is emitted (Latency to Correct) or from correct responses to retrieval of the food pellets (Latency to Reward) are shown.

% Lactic Acid	Latency to Correct	Latency to Reward
