[The functional coupling of the mechanisms for the selection of significant signals and the motor reactions they induce].

The data are described in favour of forming the integrative image of the significant signals in the mammalian brain. This image is created as a summary of the significant at this moment information, selected in the specialized areas of the cortex. The hypothesis is founded on the investigations of the cortico-striatal interrelations. They suggest that the results of the cortical analysis, which are dispersed through the specialized cortical fields, enter the striatum via the corticofugal pathways and transform into an integrative form in its neuronal network. The experimental data show that the striatal activity recorded during instrumental behaviour does not contain motor programs or commands, but reflects the peculiarity of the sensory environment, in which the movements are realized.
