Quizplus · Accepted Answer

This is true. The thalamus is responsible for receiving sensory information, and when a potential threat is detected, it sends this information directly to the amygdala. This triggers a rapid, automatic response before the cortex has a chance to fully process the information and evaluate the situation. This is known as the thalamo-amygdala pathway and is part of the brain's "quick and dirty" system for reacting to potential threats.
