title: Electrical activity of the chick embryo brain during development of stable rearrangements of movement.
abstract: A study was made of the changes in the electrical activity of the brains of 19-day old chick embryos during the development of adaptive shifts of movement in controlled experiments. It has been established that the formation of new, stable rearrangements of movement - effected under different control regimes - is accompanied by an intensification of the process of spatio-temporal synchronization of the electrical activity of the embryonic brain within the range of the dominating frequencies. This allows us to think that the spatio-temporal synchronization of the EEG activity is a manifestation of the organization of centrally-controlled influences, whereby movement is transformed adaptively at the expense of changes in the components of an endogenous, embryonic motor activity biorhythm.
