Apr 18th 2024, 16:51

Contrary to previous assumptions, nerve cells in the human neocortex are wired differently than in mice. The study found that human neurons communicate in one direction, while in mice, signals tend to flow in loops. This increases the efficiency and capacity of the human brain to process information. These discoveries could further the development of artificial neural networks.

Apr 18th 2024, 16:51

Researchers have uncovered a mechanism in the brain that allows cocaine and morphine to take over natural reward processing systems.

Apr 18th 2024, 13:26

Twin studies have proven invaluable for teasing out the effects of both genetics and the environment on human biology. Researchers studied pairs of twins to look at how the interplay of genetics and environment affect cognitive processing -- the way that people think. They found that some cognitive abilities appear to be regulated more by environmental factors than by genetics.

Apr 18th 2024, 11:18

Superior decision-making in sports such as soccer could come down to the process of inhibiting a motor response, according to a new study.

Apr 18th 2024, 11:18

A sensitive perception of the environment is crucial for guiding our behavior. However, an overly sensitive response of the brain's neural circuits to stimuli can lead to neurodevelopmental disorders such as epilepsy. Researchers now report how neuronal networks in the mouse brain are fine-tuned.

Apr 18th 2024, 11:18

In posttraumatic stress disorder (PTSD), intrusive thoughts, changes in mood, and other symptoms after exposure to trauma can greatly impact a person's quality of life. About 6 percent of people who experience trauma develop the disorder, but scientists don't yet understand the neurobiology underlying PTSD. Now, a new genetic study of more than 1.2 million people has pinpointed 95 loci, or locations in the genome, that are associated with risk of developing PTSD, including 80 that had not been previously identified.

Apr 18th 2024, 11:17

Monitoring and treating a case of multiple sclerosis requires reliable and long-term data on how the disease is progressing in the person in question. Fitness trackers and smartphones can supply this data, as a research team has now shown.

Apr 15th 2024, 16:37

Using adaptive optics, scientists have identified elusive retinal ganglion cells in the eye's fovea that could explain how humans see red, green, blue, and yellow.

Apr 15th 2024, 16:37

A study has shown that traumatic experiences during childhood may get 'under the skin' later in life, impairing the muscle function of people as they age.

Apr 12th 2024, 15:49

Engineers have developed the smallest implantable brain stimulator demonstrated in a human patient that could revolutionize treatment for drug-resistant depression and other psychiatric or neurological disorders.
