Leg movement restored in primates using wireless neural interface

An international team of scientists has used a wireless “brain-spinal interface” to bypass spinal cord injuries in a pair of rhesus macaques, restoring intentional walking movement to a temporarily paralyzed leg. The researchers say this is the first t…

Women do have better memories than men, says study

Women have better memories than men throughout life, even though their ability to recall dips at menopause. This study links memory function with hormones.

Full detonation in the hippocampus

Altering synaptic plasticity leads to a computational switch in a hippocampal synapse: the presynaptic neuron turns into “detonator” mode, causing its postsynaptic partner to fire more readily.

Alzheimer’s disease found to be a diabetic disorder of the brain

A promising treatment for Alzheimer’s disease has been found by researchers who noticed a similarity in the way insulin signaling works in the brain and in the pancreas of diabetic patients.

Increasing the activity of the neurotransmitter GABA in the brains of depressed mice has antidepressant effects

Experimentally increasing the activity of a subclass of nerve cells that produce the neurotransmitter gamma-aminobutyric acid (GABA) has antidepressant effects similar to pharmaceutical…

When do speech difficulties in children matter for literacy?

A new study found that speech difficulties are linked with difficulties in learning to read when children first start school, but these effects are no longer apparent at 8 years of age.

Researchers reveal how neurodegenerative diseases spread through the brain

Synapses, the place where brain cells contact one another, play a pivotal role in the transmission of toxic proteins. This allows neurodegenerative diseases such as Alzheimer’s to spread through the brain, scientists conclude. If the spreading of the…

Brains of those with anorexia and bulimia can override urge to eat

Scientists at the University of Colorado Anschutz Medical Campus have discovered the neurological reasons why those with anorexia and bulimia nervosa are able to override the urge to eat.

How brain surgery eliminates seizures in epilepsy patients

Surgery is an option for patients who do not respond to medications and have epileptic scar tissue that can be removed safely. In 60 to 70 percent of surgery patients, seizures are completely eliminated, and the success rate likely will improve as imag…

Autism gene slows down brain cell communication

The researchers discovered an important ‘on’ button in DIXDC1 protein that instructs brain cells to form mature connections called synapses with other brain cells during development.
