When It Comes to Feeling Pain, Touch or an Itch, Location Matters

When you touch a hot stove, your hand reflexively pulls away; if you miss a rung on a ladder, you instinctively catch yourself. Both motions take a fraction of a second and require no forethought. ...

Damage to Brain Cells Reverberates to 'Bystander' Cells

Injury or disease that afflicts a relatively small number of brain cells causes a chain reaction that stops activity across a vast network of neural circuits, according to new research. The study may ...

Novel Form of Alzheimer's Protein Found in Spinal Fluid Indicates Stage of the Disease

Researchers have found a novel form of the Alzheimer's protein tau in the fluid surrounding the brain and spinal cord. This form of tau -- known as ...

Drinking Blocks a Chemical That Promotes Attention

Scientists studied the cascade of events that begins when alcohol diminishes norepinephrine release in a brain structure called the locus ...

How Neurons Form Long-Term Memories

Neuroscientists have identified genes that memory neurons use to rewire connections after new experiences. The findings shed light on the biology of long-term memory, with implications for future ...

Five-Minute EEG Recordings: A Key to the Symptoms of Parkinson's

Pathological changes related to the disability of Parkinson's patients can already be detected in signals from the scalp without the need to open the ...

Hidden Network of Enzymes Accounts for Loss of Brain Synapses in Alzheimer's

A new study on Alzheimer's disease has revealed a previously unknown biochemical cascade in the brain that leads to the destruction of synapses, the connections between nerve cells that are ...

Researchers Find How Stress and the Circadian Clock Affect Sleep

Researchers have found a new neural pathway that links the circadian clock, stress, and wakefulness in mammals. They identified a neuron that becomes excessively active when the mammal is under ...

New Mechanism of Pain Control Revealed

Researchers have identified a unique population of astrocytes in the dorsal horn of the spinal cord of mice that produces pain hypersensitivity when activated by neurons carrying signals down from ...

How the Brain 'Re-Wires' After Disease

Researchers are studying how the brain re-wires itself in neurological disease. The team is building treatments for today's more common global conditions like Motor Neuron Disease (MND/ALS) and ...

World's First: Drug Guides Stem Cells to Desired Location, Improving Their Ability to Heal

Scientists have created a drug that can lure stem cells to damaged tissue and improve treatment efficacy -- a scientific first and major advance for the field of regenerative ...

Brain Waves Guide Us in Spotlighting Surprises

Neuroscientists have found that the dynamic interplay of different brain wave frequencies, rather than dedicated circuitry, appears to govern the brain's knack for highlighting what's ...

Newfound Ability to Change Baby Brain Activity Could Lead to Rehabilitation for Injured Brains

Researchers have identified the brain activity for the first time in a newborn baby when they are learning an association between different types of sensory experiences. Using advanced MRI scanning ...

Proteins in Motion

Membrane proteins are more efficient at reaching distal dendrites than soluble ...

Taking out the Trash Is Essential for Brain Health

Researchers have identified a protein called Wipi3 that is essential for cellular waste disposal via the alternative autophagy system. Deletion of Wipi3 in the brains of mice causes growth and motor ...

Cellular Pathway of Genetic Heart Disease Similar to Neurodegenerative Disease

Research on a genetic heart disease has uncovered a new and unexpected mechanism for heart failure. This landmark discovery found a correlation between the clumping of RNA-binding proteins long ...

Early Details of Brain Damage in COVID-19 Patients

Looking at six patients using a specialized magnetic resonance technique, researchers found that COVID-19 patients with neurological symptoms show some of the same metabolic disturbances in the brain ...

Technology Lets Clinicians Objectively Detect Tinnitus for First Time

A technology called functional near-infrared spectroscopy (fNIRS) can be used to objectively measure tinnitus, or ringing in the ears, according to a new ...

Researchers Improve Neuronal Reprogramming by Manipulating Mitochondria

Researchers have identified a hurdle towards an efficient conversion: the cell metabolism. By expressing neuron-enriched mitochondrial proteins at an early stage of the direct reprogramming process, ...

Scientists Discover New Mechanism Controlling Brain Size

International research has led to the discovery of a new mechanism that controls the size of our brains. The finding, which is based on studies on a rare congenital brain disease, delivers an ...

Promising MS Drug May Worsen Disease

The drug has not yet made it to human trials for multiple sclerosis, but scientists are urging their colleagues to move ...

Compounds Block Stress-Enhanced Nicotine Intake in Rats

Researchers have discovered that compounds that activate GABA receptors in the brain can keep rats from self-administering increased levels of nicotine during stressful conditions in an animal model ...

DNA Repair Supports Brain Cognitive Development

Researchers showed that na enzyme functions in genome maintenance by preventing double-stranded breaks in DNA during brain development in mice. In mice lacking this enzyme, these breaks occurred ...

A 'molecular volume knob' regulating electrical signals in the brain helps with learning and memory, according to a new study. The finding could help researchers in their search for ways to ...
