Which part of the brain prevents the brain from over stimulation?

The part of the brain that helps prevent overstimulation is the prefrontal cortex. This region is involved in executive functions such as decision-making, impulse control, and regulating emotions, which help manage and modulate responses to stimuli. Additionally, the amygdala plays a role in processing emotions and can influence how the brain reacts to stress or overwhelming situations. Together, these areas work to maintain balance and prevent sensory overload.
