Prior to the new study, scientists suspected involvement of the circuits ultimately implicated, but were stumped by a seeming paradox. A crossroads of convergent circuits in an emotion hub deep [...]

MIT scientists, including one of Indian-origin, have identified two populations of neurons in the amygdala that process positive and negative emotions. These neurons relay the information to [...]

Eating a slice of chocolate cake or spending time with a friend usually stimulates positive feelings, while getting in a car accident or anticipating a difficult exam is more likely to generate a [...]

Brain circuit mechanisms that can explain how positive and negative perceptions occur have been discovered by neuroscientists. The two brain activities found by experts showed the opposing events [...]

Neuroscientists have discovered brain circuitry for encoding positive and negative learned associations in mice. After finding that two circuits showed opposite activity following fear and reward [...]
