The magnitude of post reinforcement electro encephalogram synchronization in cats reflects learning ability

, : The magnitude of post reinforcement electro encephalogram synchronization in cats reflects learning ability. Brain Research 204(1): 214-219

Electrocortical alpha-like activity, termed post-reinforcement synchronization (PRS), observed during operantly conditioned behavior, was quantified in 25 cats and plotted against the number of training sessions required for each to learn to press a lever for milk reward. There was a significant correlation (r = 0.77; P < 0.001) between PRS magnitude and learning ability. The time required for learning correlated with the amount of perservation in partially reinforced, i.e., ineffective, behavioral modes.

The influence of different manners of barking of Spruce wood and of storage successively on land and in water on the amounts of pitch from sulphite pulp deposited on a metal surface. Considerably more pitch was deposited from pulp of wood stored on water than on land. Storage on land for 6 months seemed sufficient to prevent an increase in pitch after a subsequent 7-month water storage. After 7 months' storage in water, 1...
