A new study provides the first evidence for the existence of flexible neuron modules in the brain, particularly in the prefrontal cortex. These clusters of neurons can perform the same computations across varied tasks, allowing the brain to store different types of information, such as sensory input or action plans, with remarkable adaptability. This discovery suggests that reusable circuits enable the brain to generate a wide range of behaviours efficiently.
A new study has identified a region in the brainstem, the structure connecting the brain to the spinal cord, that plays a crucial role in cognitive flexibility and the ability to adapt to changing conditions. Researchers found that the 'locus coeruleus' in the brainstem is central to how the brain switches between behavioural rules, impacting disorders like ADHD, depression, and OCD.
A new study in mice reveals that psychological stress can significantly alter the gut microbiome, leading to changes in blood-forming stem cells and increasing the risk of conditions like heart disease and diabetes. Researchers found that stress impacts specific brain regions, which in turn affect intestinal microbiota balance and hematopoietic stem cell function.
This is what the new Spanish study reveals about a woman's brain after sexual assault.
