Deciding between potential actions involves coordinated activity across various cortical areas such as prefrontal, premotor, parietal, and primary motor cortex as well as interconnected subcortical regions within basal ganglia (BG). In investigating the specific function of each region in this process, the role of BG remains a matter of vigorous debate. While many studies have shown decision-related activity in BG nuclei, this activity appears significantly later than in associated cortical regions, and may not be the primary driver of decisions. Also, while BG stimulation can bias choices, in

The ability to accurately monitor the quality of one’s decisions (i.e., metacognition) is critical for adaptive decision-making. Past research has found that metacognition is enhanced when participants respond under speed pressure, possibly due to elaborated post-decisional evidence processing. Here, we investigated the time-course of evidence processing under different speed pressures using time-resolved analysis of electroencephalographic (EEG) data. Forty participants performed a motion discrimination task under short and long response deadlines. Following the initial response, participants
