New AI technology estimates brain age using low-cost EEG device
As people age, their brains do, too. But if a brain ages prematurely, there is potential for age-related diseases such as mild cognitive impairment, dementia, or Parkinson's disease. If "brain age" could be easily calculated, ...

Alteration of brain network condition could predict painful vaso-occlusive crisis in patients with sickle cell disease
A new study led by Indiana University School of Medicine researchers has found that a brain network condition called "explosive synchronization" could be the cause of extreme pain crises in people with sickle cell disease.

After spinal cord injury, neurons wreak havoc on metabolism: Study finds common drug may prevent some of the effects
Conditions such as diabetes, heart attack, and vascular diseases commonly diagnosed in people with spinal cord injuries can be traced to abnormal post-injury neuronal activity that causes abdominal fat tissue compounds to ...

New study reveals key role vision plays in sculpting brain development
Scientists have long known that our brains are organized into specialized areas, each responsible for distinct tasks. The visual cortex processes what we see, for instance, while the motor cortex governs movement. But how ...

Researchers map the spatio-temporal human brain dynamics of a visual image being recognized
For nearly a decade, a team of MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) researchers have been seeking to uncover why certain images persist in people's minds, while many others fade. To do this, ...

Researchers uncover interrelation between recency and central tendency biases in working memory
Neuroscientists have revealed that recency bias in working memory naturally leads to central tendency bias, the phenomenon where people's (and animals') judgements are biased towards the average of previous observations. ...

Brain neurons re-entering the cell cycle age quickly and shift to senescence, particularly in neurodegenerative disease
Post-mitotic neurons in the brain that re-enter the cell cycle quickly succumb to senescence, and this re-entry is more common in Alzheimer's disease, according to a new study published April 9 in the open-access journal ...

Consumption of contaminated venison suspected in cases of deer hunters with prion disease
A small team of medical workers and researchers in the U.S. has published a case study of two men, both deer hunters, who developed a rare prion disease. In their study, published in the journal Neurology, the group describes ...
Image viewing experiments challenge theory of universal internal clock
A trio of psychologists at George Mason University in the U.S. has found evidence that contradicts the theory of the universal internal clock. In their study, published in the journal Nature Human Behavior, Alex Ma, Ayana ...
New insights into the molecular mechanisms behind the action of secretagogin
An international research team, led by Tibor Harkany and Robert Schnell at Karolinska Institutet and MedUni Vienna's Center for Brain Research, set out to find ways of influencing hormone release to reduce stress reactions ...
