New insights into the opposing actions of serotonin-producing nerve fibers in mice could lead to drugs for treating addiction and major depression. Scientists in Japan have identified a nerve pathway ...

Activating a circuit between the amygdala and brainstem relieves pain and reduces defensive behaviors in rats, according to research recently published in JNeurosci. People with pain often experience ...

A summary of brainstem regions in which signal intensity changes are significantly correlated to placebo- or nocebo abilities reveals that the midbrain periaqueductal gray (PAG) – rostroventromedial ...

Researchers at the Salk Institute have discovered a brain pathway that connects the frontal cortex to the brainstem, offering potential therapeutic targets for ...

New research suggests spinal cord and brainstem are essential for processing touch signals as they travel to the brain The sense of touch is essential to almost everything we do, from routine tasks at ...

The signals that drive many of the brain and body's most essential functions—consciousness, sleep, breathing, heart rate and motion—course through bundles of "white matter" fibers in the brainstem, ...

Researchers at the Sainsbury Wellcome Center (SWC) at University College London have uncovered a neural mechanism in the brains of mice that enables the animals to overcome instinctive fears. The ...

Our survival depends on our reactions to threats. It is well known that the amygdala is central in regulating fear. But little is known about how or even if cues from our five sense organs are ...
