Dopamine: Far More Than Just the 'Happy Hormone'

Aug. 31, 2016 — Dopamine is a so-called messenger substance or neurotransmitter that conveys signals between neurons. It not only controls mental and emotional responses but also motor reactions. Dopamine is ... read more

Aug. 30, 2016 — A research team has identified the pain transmission mechanism at the molecular level and presented new solutions for the understanding of pain signals and the development of pain ... read more

Caffeine and Its Analogues Counteract Memory Deficits by Normalizing Stress Responses in the Brain

Aug. 30, 2016 — A new study describes the mechanism by which caffeine counteracts age-related cognitive deficits in animals. The study shows that the abnormal expression of a particular receptor -- adenosine A2A, a ... read more

Aug. 30, 2016 — Our brains have a detailed picture of our hands and fingers, and that persists even decades after an amputation, researchers have found. The finding could have implications for the control of next ... read more

Aug. 30, 2016 — When you try to find your way in a new place, your brain creates a spatial map that represents that environment. Neuroscientists now show that the brain’s ‘navigation system’ is not only active ... read more

People With Alcohol Dependency Lack Important Enzyme

Aug. 30, 2016 — A research group has identified an enzyme whose production is turned off in nerve cells of the frontal lobe when alcohol dependence develops. The deficiency in this enzyme leads to continued use of ... read more

Critical Protein Shows Promise for the Treatment of Alzheimer's

Aug. 30, 2016 — In new research, researchers examine p62 -- a critical protein associated with tell-tale symptoms of Alzheimer's. The study demonstrates for the first time that p62 may have a role in reversing ... read more

Use It or Lose It: Stopping Exercise Decreases Brain Blood Flow

Aug. 29, 2016 — Researchers examined cerebral blood flow in master athletes (ages 50-80 years) before and after a 10-day period during which they stopped all exercise. Using MRI brain imaging techniques, they found ... read more

Alzheimer's: Nicotinic Receptors as a New Therapeutic Target

Aug. 29, 2016 — Studies have indicated that nicotine may be beneficial for memory function. Scientists are set out to shed further light on the properties attributed to nicotine by determining the precise structure ... read more

Aug. 29, 2016 — Scientists report that a specialized drug screen test using lab-grown human cells has revealed two classes of compounds already in the pharmaceutical arsenal that may work against mosquito-borne Zika ... read more

New Window to Understanding the Brain

Aug. 29, 2016 — A team of researchers has demonstrated that syringe-injectable mesh electronics can stably record neural activity in mice for eight months or more, with none of the inflammation produced by ... read more

Single Gene Mutation Causes Severely Debilitating Disease of Brain Blood Vessels

Aug. 29, 2016 — The cause of a disease that targets blood vessels in the brain -- leading to multiple debilitating symptoms and, often, to early death -- has been tracked to a single mutated gene, opening up the ... read more

Ode to Recall: To Remember Events in Order, We Rely on the Brain's 'Symphony'

Aug. 29, 2016 — To remember events in the order they occur, the brain's neurons function in a coordinated way that is akin to a symphony, a team of scientists has found. Their findings offer new insights into ... read more

Patients With Moderate to Severe TBI Twice as Likely to Die from an Unintentional Injury

Aug. 29, 2016 — Research examining adults with moderate to severe TBI who participated in rehabilitation showed that they were twice as likely to die from an unintentional injury that occurred following their TBI. ... read more

The Brain Performs Feats of Math to Make Sense of the World

Aug. 29, 2016 — Researchers have found that the brain is quite good at rapidly and subconsciously calculating the likelihood of various events, and remain flexible enough to account for new information. They traced ... read more

Parkinson's Study Could Pave Way for Early Detection Test

Aug. 29, 2016 — A test that can detect Parkinson's disease in the early stages of the illness has moved a step ... read more

Visual Nudge Can Disrupt Recall of What Things Look Like

Aug. 26, 2016 — Interfering with your vision makes it harder to describe what you know about the appearance of even common objects, according to ... read more

Aug. 26, 2016 — Skin cells derived from autistic donors grew faster than those from control subjects, and activated their genes in distinct patterns, scientists report. Genes related to cell growth were unusually ... read more

Sertraline, Brand Named Zoloft, Improves Functioning in Young Children With Fragile X

Aug. 26, 2016 — Treatment with sertraline may provide nominal but important improvements in cognition and social participation in very young children with fragile X syndrome, the most common genetic cause of ... read more

Mechanism Identified Through Which Lead May Harm Neural Cells, Children's Neurodevelopment

Aug. 26, 2016 — Researchers have identified a potential molecular mechanism through which lead, a pervasive environmental toxin, may harm neural stem cells and neurodevelopment in ... read more
