Foundational Work on “Emotions” in Fruit Flies

SUMMARY The neural circuit mechanisms underlying emotion states remain poorly understood. Drosophila offers powerful genetic approaches for dissecting neural circuit function, but whether flies exhibit emotion like behaviors has not been clear. We recently proposed that model organisms may express internal states displaying ‘‘emotion primitives,’’ which are general characteristics common to different emotions, rather than […]

“Researchers at Northwestern University have determined that Wernicke’s area, a hotdog-shape region in the temporal lobe of the left hemisphere, may not be the seat of language comprehension, as has been scientific dogma for the past 140 years. Instead, the team suggests in a study published today (June 25) in the neurology journal Brain, understanding the meaning of words happens in the left anterior temporal lobe, while sentence comprehension is handled by a complex network of brain areas.”
