How the brain processes sensory information from internal organs

Most of us think little of why we feel pleasantly full after eating a big holiday meal, why we start to cough after accidentally inhaling campfire smoke, or why we are hit with sudden nausea after ingesting something toxic. However, such sensations are…

How the brain generates rhythmic behavior

Neuroscientists discovered the mechanism underlying the oscillator circuit that controls the rhythmic extension and retraction of whiskers in mice.

Scientists eavesdrop on communication between fat and brain

Newly discovered sensory neurons send messages from fat tissue to the brain and could eventually be co-opted to treat obesity or metabolic disease.

Drug effects of ketamine in mice can depend on the sex of the human experimenter, study finds

Researchers have shown that mice respond more to the antidepressant effects of the drug ketamine when administered by men and not by women. The group demonstrated that a stress response in a specific region of the mouse brain from handling by a man is …

Researchers visualize alpha-synuclein pathology in living patients with a neurodegenerative disorder

Multiple system atrophy (MSA) is a neurodegenerative disorder characterized by the aggregation of alpha-synuclein in the brain. Now, scientists have developed a radioligand that facilitates the imaging of alpha-synuclein aggregates in patients with MSA…

Brain bubbles: Researchers describe the dynamics of cavitation in soft porous material

A tiny bubble popping within a liquid seems more fanciful than traumatic. But millions of popping vapor bubbles can cause significant damage to rigid structures like boat propellers or bridge supports. Can you imagine the damage such bubbles could do t…

Study reveals fentanyl’s effects on the brain

Fentanyl produces a specific EEG signature distinct from other anesthetic drugs, which could make it possible to monitor its effects to enable safer, more precise, and personalized opioid administration.

Brain activity during sleep differs in young people with genetic risk of psychiatric disorders

Young people living with a genetic alteration that increases the risk of psychiatric disorders have markedly different brain activity during sleep, a new study shows.

Brain’s support cells may hold key to new Huntington’s treatments

A growing body of research suggests that the disease may also flow from defects in glia, important support cells found in the brain. The new study expands our understanding of the underlying mechanisms of the disease, and reinforces the potential of th…

Music helps patients with dementia connect with loved ones

People with dementia often lose their ability to communicate verbally with loved ones. But a new study shows how that gap can be bridged with a new music intervention. Music memories remain in the brain after patients lose language. A live ensemble pla…
