Researchers regrow damaged nerves with polymer and protein

Researchers have created a biodegradable nerve guide — a polymer tube — filled with growth-promoting protein that can regenerate long sections of damaged nerves, without the need for transplanting stem cells or a donor nerve.

Cyberbullying Linked to Increased Depression and PTSD

Cyberbullying had the impact of amplifying symptoms of depression and post-traumatic stress disorder in young people who were inpatients at an adolescent psychiatric hospital, according to a new study. The study addressed both the prevalence and factor…

Blue light triggers memory and emphatic fear in mice via a non-invasive approach

Researchers have engineered an improved biological tool that controls calcium (Ca2+) levels in the brain via blue light. This monster-OptoSTIM1 causes a change in mice’s fear learning behavior without the need of optic fiber implants in the brain.

Glutamate in the brain has unexpected qualities, researchers show with new analysis method

Researchers have achieved something long thought almost impossible — counting the molecules of the neurotransmitter glutamate released when a signal is transferred between two brain cells. With a new analysis method, they showed that the brain regulat…

Treatment for depression must also restore proper functioning of the blood-brain barrier

To better treat people with depression, not only must we treat the neurons affected by the disease, but we must also restore the integrity of the barrier that regulates exchanges between blood circulation and the brain.

Human exposure to aluminum linked to familial Alzheimer’s disease

A new study supports a growing body of research that links human exposure to aluminum with Alzheimer’s disease (AD). Researchers found significant amounts of aluminum content in brain tissue from donors with familial AD. The study also found a high deg…

Rich rewards: Scientists reveal ADHD medication’s effect on the brain

Researchers have identified how certain areas of the human brain respond to methylphenidate — a stimulant drug which is used to treat symptoms of ADHD. The work may help researchers understand the precise mechanism of the drug and ultimately develop m…

America’s most widely consumed oil causes genetic changes in the brain

New research shows soybean oil not only leads to obesity and diabetes, but could also affect neurological conditions like autism, Alzheimer’s disease, anxiety, and depression.

Mix of stress and air pollution may lead to cognitive difficulties in children

Children with elevated exposure to early life stress in the home and elevated prenatal exposure to air pollution exhibited heightened symptoms of attention and thought problems, according to researchers. Early life stress is common in youth from disadv…

How decisions unfold in a zebrafish brain

Researchers were able to track the activity of each neuron in the entire brain of zebrafish larvae and reconstruct the unfolding of neuronal events as the animals repeatedly made ‘left or right’ choices in a behavioral experiment. The resulting frame-b…
