General and local changes in the electroencecphalogram during the formation of conditioned motor reflexes in man

Summary

The author studied the EEG changes in man during the formation of conditioned motor reflexes to complex sound stimuli.

The data obtained permit 3 types of reactions to be distinguished: 1) A generalized depression of the alpha-rhythm; 2) a local depression of the alpha-rhythm in the motor area of the “active” hemisphere, and 3) a depression in the form of a “funnel.”

In the latter, the depression started from the motor area, and subsequently spread in the occipital direction. The recovery of the alpha-rhythm proceeded in the reverse direction. Depression in the motor area was retained the longest.

In the author's opinion, these changes in the electroencephalogram reflect an irradiating process in the cerebral cortex with its subsequent concentration.
