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, 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.

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.
