A clue as to why it's so hard to wake up on a cold winter's morning

Do you remember the challenge of waking up on winter's cold, dark days? Neurobiologists have uncovered a clue to what's behind this behavior. In a study of the fruit fly, the researchers have identified a 'thermometer' circuit that relays information[…]

Blood flow recovers faster than brain in micro strokes

Neurobiologists show that increased blood flow to the brain is not an accurate indicator of neuronal recovery after a microscopic stroke.

Brain's 'updating mechanisms' may create false memories

New research is one of the first comprehensive characterizations of poorly formed memories and may offer a framework to explore different therapeutic approaches to fear, memory and anxiety disorders. It may also have implications for accuracy of some witness testimony.

Scientists identify gene linked to thinness that may help resist weight gain

Researchers used a genetic database of more than 47,000 people in Estonia to identify a gene linked to thinness that may play a role in resisting weight gain in metabolically healthy thin people. They show that knocking out this gene[…]

Unconscious: 'Sniff test' predicts recovery of consciousness

If an unconscious person responds to smell through a slight change in their nasal airflow pattern -- they are likely to regain consciousness. This is the conclusion from a new study.

Family environment affects adolescent brain development

Childhood environment and socioeconomic status affect cognitive ability and brain development during adolescence independently of genetic factors, researchers report. The study demonstrates how important the family environment is, not just during early infancy but also throughout adolescence.

Exercise improves memory, boosts blood flow to brain

Scientists have collected plenty of evidence linking exercise to brain health, with some research suggesting fitness may even improve memory. But what happens during exercise to trigger these benefits?

Protein shapes matter in Alzheimer's research

Even a small change may cause long-term consequences. For amyloid beta peptides, a major hallmark of Alzheimer's disease, a common chemical modification at a particular location on the molecule has a butterfly effect that leads to protein misfolding, aggregation and[…]

Observing the freely behaving brain in action

Scientists working at Caesar have developed a small head-mounted microscope that allows access to the inner workings of the brain. The new system enables measurement of activity from neuronal populations located in the deep cortical layer with single-cell resolution, in[…]

Found: Brain structure that controls our behavior

Solving problems, planning one's own actions, controlling emotions -- these executive functions are fundamental processes for controlling our behavior. Despite numerous indications, there has not yet been any clear evidence to support which brain areas process these abilities. A study[…]

Artificial pieces of brain use light to communicate with real neurons

Researchers have created a way for artificial neuronal networks to communicate with biological neuronal networks. The new system converts artificial electrical spiking signals to a visual pattern than is then used to entrain the real neurons via optogenetic stimulation of[…]

Not all multiple sclerosis-like diseases are alike

Scientists say some myelin-damaging disorders have a distinctive pathology that groups them into a unique disease entity.

Brain-to-gut connections traced

Using rabies virus injected into the stomach of rats, researchers trace the nerves back to the brain and find distinct 'fight or flight' and 'rest and digest' circuits. These results explain how mental states can affect the gut, and present[…]

Scientists find brain center that 'profoundly' shuts down pain

A research team has found a small area of the brain in mice that can profoundly control the animals' sense of pain. Somewhat unexpectedly, this brain center turns pain off, not on. It's located in an area where few people[…]

The brain's facial recognition area doesn't differentiate outgroup members

A quirk in how the brain processes faces makes it harder to tell members of a racial outgroup apart, according to new research.

How experiencing traumatic stress leads to aggression

Traumatic stress can cause aggression by strengthening two brain pathways involved in emotion, according to new research. Targeting those pathways via deep brain stimulation may stymie aggression associated with post-traumatic stress disorder.

High five! It's possible to create proximity online

Despite physical distance, it's possible to create proximity between family members located in different places. This is according to a study that has investigated how video calls bring family members together. The results show that proximity in video calls is[…]

Maintaining heart health may protect against cognitive decline

People with a higher risk of developing cardiovascular disease have increased cognitive decline, including an increase in typical markers of Alzheimer's disease, suggesting that monitoring and controlling for heart disease may be key to maintaining and improving cognitive health later[…]
