Cause of sleep disturbance in cardiac disease identified: Ganglia play previously unrecognized role

Around one third of people with heart disease suffer from sleep problems. A team now shows that heart diseases affect the production of the sleep hormone melatonin in the pineal gland. The link between the two organs is a ganglion in the neck region. T…

Volunteering in late life may protect the brain against cognitive decline and dementia

Volunteering in late life is associated with better cognitive function — specifically, better executive function and episodic memory.

Treatment at the first signs of MS could mean lower risk of disability later

People who start taking medication soon after the first signs of multiple sclerosis (MS) may have a lower risk of disability later, according to a new study.

Understanding brain network connecting temperature sensation and emotion may help prevent heatstroke

Researchers have uncovered remarkable new insights into the neural pathways of the brain that allow people to act to regulate their body temperature in response to changes in the environment. Their study has revealed two previously unidentified distinc…

Scientists ID cells involved in correcting errors during spatial navigation

Neurons become active when mice exploring a maze correct after making a wrong turn.

Study sheds light on where conscious experience resides in brain

The brain registers what we see even if we are not consciously aware of it. We even react emotionally to the content. How is this possible? A new experiment reveals that, while various regions of the brain register brief activity when a new image is vi…

AI-guided brain stimulation aids memory in traumatic brain injury

AI-guided electrical stimulation in the brains of patients with traumatic brain injury improved memory, a collaborative new study shows. This builds on previous research involving epilepsy patients without traumatic brain injury. Brain injuries can res…

Lewy body disease can be detected before symptoms

Lewy body disease is the second most common neurodegenerative disease after Alzheimer’s disease. A research group has now shown that the disease can be detected before symptoms appear, using a spinal fluid test. Researchers also demonstrate that reduce…

Fear is in the eye of the beholder

Averting our eyes from things that scare us may be due to a specific cluster of neurons in a visual region of the brain, according to new research. Researchers found that in fruit fly brains, these neurons release a chemical called tachykinin which app…

Boosting certain brain cells diminished hypersensitivity in Fragile X mice

Study suggests modulating the activity of certain neurons could be an effective approach to restoring circuit function.
