Researchers use light-activated drugs to map the brain's internal painkillers

Placebo effects, in which patients experience relief without therapeutic treatment, increasingly have been considered as potentially powerful clinical treatments for ailments such as depression and pain. Yet the neurological mechanisms underlying such processes are not fully understood. Now, a multi-institutional team led by the University of California San Diego's Matthew Banghart, an associate professor in the School of Biological Sciences, has pinpointed the brain circuitry responsible for placebo pain relief.

Categorization is fundamental and predictive across all brain processing

Challenging the classic view, two cognitive scientists argue in a new review that categorization is not a late, specialized stage of sensory processing.

Study reveals brain mechanisms behind post-stroke urinary incontinence

A new USC-led study using functional magnetic resonance imaging (fMRI) reveals the neural mechanisms that contribute to urinary incontinence, a common condition affecting stroke survivors that has a significant impact on their quality of life.

Study reveals how tau tangles spread from one brain region to another in Alzheimer's

Alzheimer's disease is a progressive neurodegenerative disorder that slowly impairs memory, affects thinking skills, and eventually interferes with daily functioning.

Brain study reveals sender and receiver roles in default mode network

The default mode network (DMN) is a distributed set of interconnected brain regions that has long been associated with internally oriented cognition such as remembering the past, thinking about the future, or thinking about oneself.

Study questions benefits of fish oil after mild brain injuries

A first-of-its-kind study led by the Medical University of South Carolina raises questions about the value of fish oil supplements for people with repetitive mild traumatic brain injuries.

Calcium channel mutations disrupt early brain development and cause epilepsy

Researchers at Baylor College of Medicine have uncovered a previously unrecognized mechanism by which inherited calcium channel mutations disrupt early brain development and predispose children to epilepsy and related cognitive challenges.

Regulatory T cells may influence inflammation and behavior in autism

Two new studies from the UC Davis MIND Institute examined regulatory T cells (Tregs) and their potential role in neuroinflammation and behavioral changes associated with autism.

Researchers settle 60-year debate on the fundamental mechanisms of visual perception

A scientific dispute spanning six decades about fundamental mechanisms of visual perception in mammals has now been settled. Researchers at TUM have succeeded in observing the visual information flow from neuron to neuron.

New brain circuit discovery offers hope for chronic pain treatment

A new map of a brain circuit specific to chronic pain suggests a promising route to treatment for the roughly 60 million Americans living with persistent pain, according to a study published in Nature.

DNA damage in gray matter neurons linked to MS progression

For decades, multiple sclerosis research has focused on myelin, the insulation around the brain's wiring. Scientists paid less attention to another loss that was happening in parallel: neurons in the cortex, the seat of higher thinking and cognition, were quietly dying.

The brain encodes time and space through common neural sequences

If you develop Alzheimer's disease, you not only lose your sense of time, but you also lose your sense of place. Could time and place be two sides of the same coin?

New optogenetic method precisely controls marmoset brain communication pathways

Understanding how the brain works requires more than studying single regions in isolation. The cerebral cortex depends on long-distance connections that link specialized areas into coordinated networks.

Novel MRI technique reveals sleep-driven brain cleansing mechanisms

Sleep helps the brain to cleanse itself – and now this process can be measured in humans entirely non-invasively.

Excessive RNA editing enzyme alters brain circuit formation in Down syndrome

A collaborative research study co-led by scientists at the Icahn School of Medicine at Mount Sinai and the Liber Institute for Brain Development has for the first time identified a biological process that may help explain how the brain develops differently in people with Down syndrome.

NOX-1 identified as key molecular target to prolong ketamine's antidepressant effects

Treatment-resistant depression affects a large proportion of people with major depressive disorder, and while ketamine offers rapid relief, its antidepressant effects fade within a few weeks.

Scientists discover how brain development programs fuel pediatric tumors

A team of researchers at Baylor College of Medicine, St. Jude Children's Research Hospital, Texas Children's Hospital, and collaborating institutions reveals in the journal Nature a novel mechanism that drives the development of pediatric supratentorial ependymoma (EPN), the third most common pediatric brain tumor. The findings suggest potential new approaches to treat these aggressive and chemo-resistant tumors.

Chronotherapy offers new hope for timing pain relief to match body cycles

Time plays a key role in our perception of pain and administering pain relief and medication for chronic pain-related depression may be more effective at certain times of day, UCL and University of Toronto researchers say.
