Error monitoring is commonly studied using various inhibitory control tasks, involving response withholding, response cancellation, or response selection. However, it remains unclear whether there is a common neural mechanism underlying error monitoring across these tasks or if it is specific to distinct types of cognitive failures. To identify both similarities and differences in the neural processing of errors across go/no-go, stop-signal, and flanker tasks, we employed microstate analysis. This method allows to study the dynamically evolving topographical patterns of neural activity throughout the brain. Our results revealed that the early phase of error monitoring in all tasks predominantly engages the supplementary motor area. In addition, we observed task-specific neural activity encompassing visual and motor areas in the go/no-go task, the dorsal part of the anterior cingulate cortex in the stop-signal task, and its ventral part in the flanker task. These findings suggest that error monitoring involves a collection of interconnected cognitive processes, rather than a uniform mechanism across tasks.
