Researchers have observed what happens in the brains of mice whose forepaws perceive vibrations. They discovered that neurons in the somatosensory cortex are activated in a manner similar to those in the sound-reactive auditory cortex. These results suggest that feeling a phone vibrate or hearing it ring is ultimately based on the same brain codes.

Scientists at Scripps Research have found that they can reverse the desire to drink in alcohol-dependent rats—with the flip of a switch. The researchers were able to use lasers to temporarily inactivate a specific neuronal population, reversing alcohol-seeking behavior and even reducing the physical symptoms of withdrawal.

Researchers have identified changes in brain connectivity and brain activity during rest and reward anticipation in children with anhedonia, a condition where people lose interest and pleasure in activities they used to enjoy.

Researchers have outlined a way to classify neurons based not only on how they look, but on with which other neurons they are capable of communicating.
