Congratulations to Drs. Sahib Khalsa and Justin Feinstein on their intriguing Journal of Neuroscience article featured by the editors in the current issue!
"In a pair of twin sisters, a rare disease had damaged the brain’s structures believed necessary to feel fear. But an injection of a drug [isoproterenol] could nevertheless make them anxious." The results suggest that the amygdala isn’t the only part of the brain involved in fear and anxiety. Determining the additional systems involved could provide key neural targets for future anxiety treatments.
