LeDoux's model of emotion, specifically fear processing, suggests that sensory input is first received by the thalamus, which then splits the signal. One part of the signal is sent directly to the amygdala for a quick, albeit less precise, response. The other part is sent to the cortex for a more detailed analysis before it reaches the amygdala. This dual pathway allows for both rapid and more thoughtful responses to stimuli.
