[Functional brain asymmetry and changes in the structure of the visual space in emotional pathology and psychotropic exposures].

By means of graphic test (drawing on irregular grid) the preference of the space parts by patients in depressive and maniac states and also after the injection of psychotropic agents (antidepressants and neuroleptics) was studied. In depression and also after the injection of neuroleptics such modus of graphic test execution was revealed which can be conditionally determined as integral structuring of the space with the preference (high actuality) to its left part. The proofs are given that such type of test execution is typical for predominance of activation of the right hemisphere over the left one. In the manic state and after administration of improving mood drugs, a quite different type of grid filling is revealed, which is determined as fractional structuring of space with a decrease of actuality of its left part. Such type of space representation is typical for predominance of activation of the left hemisphere over the right one.
