When epileptic patients suffer seizures, their brain is undergoing repetitive and excessive neuronal firing. But what triggers this has stumped scientists for years. Now, researchers have used fluorescence calcium sensors to track astrocytes’ role in e…

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 ca…

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 neurona…

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 scientist…

Thought emerges and is controlled in the brain via the rhythmically and spatially coordinated activity of millions of neurons, scientists argue in a new article. Understanding cognition and its disorders requires studying it at that level.

Scientists created four cannabis-derived CBN analogs (chemical look-a-likes) with enhanced neuroprotective properties and potential for therapeutic application in neurological disorders like Alzheimer’s, Parkinson’s, and traumatic brain injury. Their f…

Investigators have discovered how brain cells responsible for working memory — the type required to remember a phone number long enough to dial it — coordinate intentional focus and short-term storage of information.

A growing body of research shows that exposure to air pollution, especially during pregnancy and childhood, may have a negative impact on brain development. Now a study has found that exposure to nitrogen dioxide (NO2) during the first two years of lif…

Researchers have advanced the understanding of how the cerebral cortex develops by tracing the lineage of certain brain cells.

A research team reports that social stress during adolescence in female mice later results in prolonged elevation of the hormone cortisol after they give birth.
