When an organism is exposed to environmental stimuli of varying intensity, the adaptive changes in CNS can be explained by several conceptual provisions: law motivation-activation Yerkes and Dodson, laws force pessimal protective inhibition, theory emotion activation. Later, reinforcement sensitivity was developed fields psychology psychophysics. At same time, cortical prepulse inhibition (PPI), perceived stimulus intensity (PPIPSI), augmentation/reduction phenomenon were proposed sensory neurophysiology, which expanded our understanding consciousness. The aim this study identify markers levels activity cognitive processes under normal psychopathological conditions while amplifying information stimulus. For purpose, we changed contrast level reversible checkerboard patterns mapped visual evoked potentials (VEPs) 19 monopolar channels among 52 healthy subjects 39 patients with a mental illness without active productive pathology.
