All Too Human: The Price We Pay for Our Advanced Brains May Be a Greater Tendency to Disorders

Neuroscience NewsJanuary 22, 2019

Researchers report the neural code of the prefrontal cortex is more efficient than the amygdala in both humans and primates. The lower resistance of the amygdala to errors in humans may play a role in exaggerated survival responses, such as those seen in anxiety and PTSD.... Read More...
