- Аннотация: Abstract—The parameters and topography of negative ERP components in response to (Go) and (NoGo)stimuli, depending on the individual saccadic latency (LP), were analyzed in a Go/NoGo paradigm. The objective of the work was to study the functional significance of the N1 (150) and N2 (250) components in“fast” (LP = 180 ± 7 ms) and “slow” (LP = 271 ± 8 ms) subjects in a saccadic Go/NoGo paradigm. The N1component had higher amplitude in slow subjects in the Go conditions and in fast subjects in the NoGo conditions. In NoGo conditions, the N1 latency was higher in fast subjects, while slow subjects had higher N2latency. The differences detected in the parameters and topography of the N1 and N2 components allow us to consider the Go-N1 component as a correlate of directed attention at the stage of stimulus analysis in slowsubjects and at the stage of decision-making and saccade initiation in fast subjects. The NoGo-N2 compo nent may be considered as a correlate of decision-making and response inhibition in slow subjects and as acorrelate of inhibitory response monitoring and memory updating in “fast” subjects. The detected differences prior to a saccadic response in the pre-stimulus period may be explained by a higher level of motor readiness in fast subjects and a higher level of nonspecific inhibition in the motor system of slow ubjects.Keywords: saccade, negative 1 ERP components, Go/NoGo paradigm, cognitive control, attention, inhibi-tion, decision-makingDOI: 10.1134/S0362119722010145
