First direct evidence for ultra-fast responses in human amygdala to fear

For the first time, an international team of scientists has shown that the amygdala in the human brain is able to detect possible threats in the visual environment at ultra-fast time scales. By measuring the electrical activity in the amygdala of patients that had been implanted with electrodes in order to better diagnose their epilepsy, the researchers provide new data on how information travels between the visual and emotional networks.
