Every time you eat, your body goes through a complex process to decide when you’ve had enough. The sensation of fullness, ...

Researchers have revealed neural circuits in the brainstem that are crucially involved in implementing decisions by controlling three fundamental behavioral states or strategies: perseverance, ...

In the animals, we found that at the time of the sudden apnea, similar hyperexcitable conditions occurred in the brainstem. These conditions lead to a sudden wave of neuronal firing that was ...

Recent research reveals how spinal health may influence the gut-brain connection, offering new perspectives on managing ...

Columbia scientists have identified specialized brainstem neurons that tell mice when to stop eating. These cells integrate sensory and hormonal signals to regulate meal size and respond to ...

Toward the bottom of the brain are more primitive structures, including the cerebellum and brain stem. These also fulfill critical functions. Running through parts of the brain are a dozen pairs ...

For the first time, researchers have been able to observe how the pupils react during sleep over a period of several hours. A ...

Functional magnetic resonance imaging (fMRI) of the whole brain with cardiac triggering allowed simultaneous observation of activity in the brainstem, thalamus and cerebrum. This work shows that ...

For the first time, researchers have been able to observe how the pupils react during sleep over a period of several hours. A look under the eyelids showed them that more happens in the brain during ...
