Biologist leads pioneering study on stress

A biologist conducted a pioneering research study that could help us to better understand the role of dopamine in stress resilience in humans through analyzing wild songbirds. This study could lead to increased prevention and treatment of stress-related disorders.

Newly discovered neural pathway processes acute light to affect sleep

Either to check the time or waste time, people often look at their smartphones after waking in the middle of the night. While this acute burst of light does make it more difficult to fall back to sleep, a new[…]

Boosting the discovery of new drugs to treat spinal cord injuries using zebrafish

A research team led by Leonor Saúde, Principal Investigator at Instituto de Medicina Molecular, in partnership with the company Technophage, SA, has designed a simple and efficient platform that uses zebrafish to discover and identify new drugs to treat spinal[…]

Alzheimer's gene may impact cognitive health before adulthood

A psychologist asserts that those carrying the APOE4 gene score lower on IQ tests during childhood and adolescence. And the effect was stronger in girls than in boys. APOE4 carriers are up to three times more likely to develop late-onset[…]

Scientists stimulate neurons to induce particular perceptions in mice's minds

Hallucinations are spooky and, fortunately, fairly rare. But, a new study suggests, the real question isn't so much why some people occasionally experience them. It's why all of us aren't hallucinating all the time.

Physicists use mathematics to trace neuro transitions

Unique in its application of a mathematical model to understand how the brain transitions from consciousness to unconscious behavior, a study may have just advanced neuroscience appreciably. The findings, surprisingly by physicists, suggest that the subliminal state is the most[…]

New pathways for sensory learning in the brain

Researchers have developed an automated, robotic training device that allows mice to learn at their leisure. The technology stands to further neuroscience research by allowing researchers to train animals under more natural conditions and identify mechanisms of circuit rewiring that[…]

Biomaterial-delivered chemotherapy leads to long-term survival in brain cancer

A combination of chemotherapy drugs during brain cancer surgery using a biodegradable paste, leads to long-term survival, researchers have discovered.

How mammals' brains evolved to distinguish odors is nothing to sniff at

Neuroscientists have discovered that at least six types of mammals -- from mice to cats -- distinguish odors in roughly the same way, using circuitry in the brain that's evolutionarily preserved across species.

Neuroscientists discover neuron type that acts as brain's metronome

By measuring the fast electrical spikes of individual neurons in the touch region of the brain, neuroscientists have discovered a new type of cell that keeps time so regularly that it may serve as the brain's long-hypothesized clock or metronome.

Should obesity be recognized as a disease?

With obesity now affecting almost a third (29%) of the population in England, and expected to rise to 35% by 2030, should we now recognize it as a disease? Experts debate the issue.

Can gut infection trigger Parkinson's disease?

Results suggest some forms of Parkinson's disease are an autoimmune disease triggered years before noticeable symptoms.

Cell types affected in brains of multiple sclerosis patients pinpointed

Scientists have discovered that a specific brain cell known as a 'projection neuron' has a central role to play in the brain changes seen in multiple sclerosis (MS). The research shows that projection neurons are damaged by the body's own[…]

Parkinson's: New study associates oxidative stress with the spreading of aberrant proteins

Oxidative stress could be a driving force in the spreading of aberrant proteins involved in Parkinson's disease.

How the brain distinguishes between voice and sound

Is the brain capable of distinguishing a voice from phonemes? Researchers devised pseudo-words spoken by three voices. Their aim? To observe how the brain processes this information when it focuses either on the voice or phonemes. The scientists discovered that[…]

Older adults: Daunted by a new task? Learn 3 instead

Learning several new things at once increases cognitive abilities in older adults, according to new research. After just 1.5 months learning multiple tasks in a new study, participants increased their cognitive abilities to levels similar to those of middle-aged adults,[…]

Exercise offers protection against Alzheimer's

Higher levels of daily physical activity may protect against the cognitive decline and neurodegeneration (brain tissue loss) from Alzheimer's disease.

Novel therapy administered after TBI prevents brain damage

Could a therapy administered 30 minutes after a traumatic brain injury prevent damage that leads to seizures and other harmful effects? Researchers think so.

Risk and progression of Alzheimer's disease differs by sex

The abnormal accumulation of proteins in the brain is a biological marker for Alzheimer's disease, but the ways in which these proteins spread may help explain why the prevalence of Alzheimer's is higher in women than in men.
