Study finds an increase in depression symptoms among UK adults aged 50-plus during the pandemic

The mental health of UK adults over the age of 50 has been significantly compromised by the Covid-19 pandemic, with females and those in urban areas affected the most, reveals a new study from the University of Surrey.

New type of algorithm simplifies comparisons between effects of electrical stimulation on the brain

For millions of people with epilepsy and movement disorders such as Parkinson's disease, electrical stimulation of the brain already is widening treatment possibilities. In the future, electrical stimulation may help people with psychiatric illness and direct brain injuries, such as stroke.

Neuroscientists visualize ultrastructural changes to dendritic spines during structural plasticity

Researchers at the Max Planck Florida Institute for Neuroscience have developed a new imaging technique capable of visualizing the dynamically changing structure of dendritic spines with unprecedented resolution.

Using an internal cognitive map to solve abstract problems

How do we make decisions about a situation we have not encountered before? New work from the Center for Mind and Brain at the University of California, Davis, shows that we can solve abstract problems in the same way that we can find a novel route between two known locations - by using an internal cognitive map.

Researchers develop statistical model to characterize how ketamine anesthesia affects the brain

By developing the first statistical model to finely characterize how ketamine anesthesia affects the brain, a team of researchers at MIT's Picower Institute for Learning and Memory and Massachusetts General Hospital have laid new groundwork for three advances: understanding how ketamine induces anesthesia; monitoring the unconsciousness of patients in surgery; and applying a new method of analyzing brain activity.

NIH awards $18.15 million to seven projects focused on interoception

The National Institutes of Health is awarding seven projects a total of $18.15 million over five years to a new effort focused on interoception—the ways in which organisms sense and regulate signals within their bodies.

Study: Epilepsy brain implant does not induce changes to patients' personalities or self-perceptions

A next-generation brain implant currently in clinical use for treating refractory epilepsy – to help prevent symptoms including seizures – does not induce changes to patients' personalities or self-perceptions, a new study of patient experiences shows.

People with MS and depression have an increased risk of death, study shows

Depression is common in people with multiple sclerosis (MS), and a new study shows that people with both conditions may be more likely to die over the next decade than people with just one or neither condition.

Researchers find new reward circuitry beyond dopamine

The key to overcoming addictions and psychiatric disorders lives deep inside the netherworld of our brains and the circuitry that causes us to feel good.

How rape affects memory, and why police need to know about that brain science

Annie Walker woke up one morning in 2019 with little recollection of the night before. She had bruises on her arms, legs, wrist and lower abdomen.

Study uses novel technology to map the brain circuitry of spirituality

Scientists have long suspected that religiosity and spirituality could be mapped to specific brain circuits, but the location of those circuits remains unknown. Now, a new study using novel technology and the human connectome, a map of neural connections, has identified a brain circuit that seems to mediate that aspect of our personality. The work appears in Biological Psychiatry, published by Elsevier.

Neurons in visual cortex of the brain change their responses over time, research reveals

New research from Washington University in St. Louis reveals that neurons in the visual cortex - the part of the brain that processes visual stimuli - change their responses to the same stimulus over time.

Large analysis identifies 579 genetic locations linked to anti-social behavior and addiction

An analysis of data from 1.5 million people has identified 579 locations in the genome associated with a predisposition to different behaviors and disorders related to self-regulation, including addiction and child behavioral problems.

Higher intake of specific nutrients linked to lower brain iron and better cognition in older adults

Research conducted at the University of Kentucky College of Medicine suggests that higher intake of specific nutrients is associated with lower brain iron concentration and better cognitive performance in older adults.

Study identifies 579 genomic regions associated with predisposition to self-regulating behaviors

Researchers have identified 579 locations in the human genome associated with a predisposition to self-regulation-related behaviors, including addiction and child behavioral problems. With data from 1.5 million people of European descent, the effort is considered to be one of the largest genome-wide association studies to date.

Review highlights similarities between long COVID and chronic fatigue syndrome

A team of researchers, including two from Johns Hopkins Medicine, have published a review article highlighting similarities between certain lingering symptoms following COVID-19 illness — a condition called "long COVID" — and myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), a debilitating, complex disorder previously known as chronic fatigue syndrome.

Athletes with history of concussions may show subtle and chronic brain changes

A new study suggests athletes with a history of concussion may show more brain injury from a later concussion, particularly in middle regions of the brain that are more susceptible to damage, when compared to athletes with no history of concussion.
