Where does this come from, and can I check it?

A short subcortical pathway reaches it in milliseconds, ahead of conscious appraisal. The figure is taken from NIMH, which is linked in full on this page. Every fact on Mondo Knows names its source rather than repeating an unsourced claim.

Is this really a human body fact?

Yes. It sits on the Human Body shelf, one of 2,600 sourced facts grouped into space, animals, the human body, history, science and more. Category pages collect every fact in the same field.

What else can I read about it?

Mondo Knows Facts

The amygdala reacts to threats before the cortex

A short subcortical pathway reaches it in milliseconds, ahead of conscious appraisal Sensory input can travel from the thalamus straight to the amygdala, skipping the cortex. That fast route produces a startle or a rush of arousal before the situation is understood. The cortex then provides a slower, more accurate assessment that can override the first reaction. It sits in Mondo's human body collection, one of 200 facts that each trace back to the reference below.
