Using optogenetics to 'switch off' the insular cortex in mice experiencing a painful event resulted in a less fearful reaction to pain. The ability of the mice to learn avoidance from the pain event was also reduced.
Functional olfactory receptors have been identified in human taste cells. The findings suggest olfactory receptors play a role in the taste system by interacting with taste receptors on the tongue. The brain, researchers say, combines input from taste, smell and other senses to create a multi-modal sensation of flavor.
Researchers say those who use both cannabis and nicotine have greater brain connectivity that those who take one or the other. The networks of those who used both substances closely resembled those who people who took neither drug.

In order to reduce anxiety, the human brain suppresses the sensory effects of the heartbeat, a new study reports.
A neuroimaging study links the different symptoms of schizophrenia to neurological disruption in multiple brain areas.
Researchers discover a functional link between an area of the brain associated with taste memory and an area associated with encoding the time and place the memory occurred.
Part of the brain associated with empathy showed stronger activation when study participants watched the suffering of hateful people, as opposed to those who were more likable, researchers discover.
