A team of New Jersey researchers has shown that changes in perceptual certainty and response bias, two central metrics of signal detection theory (SDT), correlate with changes in cognitive fatigue. They also show that SDT measures change as a function of changes in brain activation. This finding was reported in Frontiers in Psychology on January
Bipolar disorder affects millions of Americans, causing dramatic swings in mood and, in some people, additional effects such as memory problems. While bipolar disorder is linked to many genes, each one making small contributions to the disease, scientists don’t know just how those genes ultimately give rise to the disorder’s effects. However, in new research,

Anabolic-androgenic steroids (AAS), a synthetic version of the male sex hormone testosterone, are sometimes used as a medical treatment for hormone imbalance. But the vast majority of AAS is used to enhance athletic performance or build muscle because when paired with strength training. AAS use increases muscle mass and strength, and its use is known
Dental cavities could significantly increase the risk of a life-threatening stroke from bleeding in the brain, according to new research. Past studies have shown a link between gum infection and stroke, but few studies have looked into what role dental cavities might play. In the new study, researchers looked specifically at cavities and intracerebral stroke,
Music-based interventions have become a core ingredient of effective neurorehabilitation in the past 20 years thanks to the growing body of knowledge. In this theme issue of Neurorehabilitation, experts in the field highlight some of the current critical gaps in clinical applications that have been less thoroughly investigated, such as post-stroke cognition, traumatic brain injury,
What: The Brain Prize has been awarded to Michael A. Moskowitz, M.D., a professor of neurology at Harvard Medical School at the Massachusetts General Hospital, Charlestown, who also is supported by an NIH grant. The Brain Prize is "the world's most prestigious award for brain research" and is awarded by the Lundbeck Foundation, Denmark. Dr.
Using genetic engineering, researchers at UT Southwestern and Indiana University have reprogrammed scar-forming cells in mouse spinal cords to create new nerve cells, spurring recovery after spinal cord injury. The findings, published online today in Cell Stem Cell, could offer hope for the hundreds of thousands of people worldwide who suffer a spinal cord injury
Research from the University of Kent has led to the development of the MeshCODE theory, a revolutionary new theory for understanding brain and memory function. This discovery may be the beginning of a new understanding of brain function and in treating brain diseases such as Alzheimer’s. In a paper published by Frontiers in Molecular Neuroscience,
The coronavirus disease 2019 (COVID-19) pandemic has claimed well over 2.4 million lives, but its long-term sequelae are still being identified. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) produces an infection that may be associated with a wide spectrum of disease, from asymptomatic to critical or terminal respiratory failure or multi-organ dysfunction. A new
How come we don't hear everything twice: After all, our ears sit on opposite sides of our head and most sounds do not reach both our ears at exactly the same time. While this helps us determine which direction sounds are coming from, it also means that our brain has to combine the information from
Amyloid plaques are aggregates of misfolded proteins that form in the spaces between nerve cells. These abnormally configured proteins are thought to play a central role in Alzheimer's disease. The amyloid plaques first develop in the areas of the brain concerned with memory and other cognitive functions. The amyloid hypothesis Amyloid plaques form when pieces
Amnesia or memory loss is associated with stress, anxiety and frustration and is often very distressing for the patient as well as for his or her family and friends. Types of treatment for amnesia Treatment of amnesia and memory loss include (1-4): Cognitive therapy using speech or language therapist can be of help in patients

The definition of vision impairment by the Centers for Disease Control and Prevention (CDC) says a visually impaired person’s eyesight cannot be corrected to a “normal level”. It may be said that visual impairment is the functional limitation of the eye or eyes or the vision system. This leads to (1-5) – Loss of visual
It is important to remember that no two persons with brain cancer tend to show same symptoms or signs. In addition, brain tumors and cancers may be sometimes difficult to diagnose as most of their symptoms and signs are commonplace and sometimes overlap with other ailments. That said, the severity and extent of symptoms caused
Anxiety is an adaptive response that is of great benefit to all life forms. It triggers fear learning, i.e., survival instincts that alert an organism to its surroundings and the dangers that prevail in it. However, extreme anxiety that is inappropriate to a circumstance and is prolonged is a negative emotion, labeled as a social
As a society, Westernized people are increasingly conscious of the types of food we consume and the effect they have on weight and health. More and more people are following diet plans to manage their weight. The ketogenic or keto diet is one commonly followed plan which shares some features with other well-known diets such
Patients in a coma are described as being in a state of unconsciousness from which they cannot be woken and are unresponsive. Typical causes of coma include stroke, seizures, severe head injury, infection of the brain such as encephalitis, or alcohol poisoning. Those with diabetes pose an additional risk of falling into a coma if
Skip to: A Promise for PTSD Patients Warm Acupuncture for A Restful Night’s Sleep Scalp Acupuncture to Stimulate Brain Activation in the Elderly The exact means by which acupuncture affects the central nervous system is unclear. The practice of acupuncture is widespread – both in the world, and across the body. It can be applied
