A team of biologists has isolated genes that regulate the sleep-feeding conflict. The study offers new insights into how the brain chooses between behaviors that are critical for survival.
Genes and brain centers that regulate meal size in flies identified Biologists have identified two genes, the leucokinin neuropeptide and the leucokinin receptor, that appear to regulate meal sizes and frequency in fruit flies. Both genes have mammalian counterparts that seem to play a similar role in food intake, indicating that the steps that control meal size and meal frequency are not just behaviorally similar but are controlled by the same genes throughout t
Autism Genes Discovered; Help Shape Connections Among Brain Cells Scientists have connected more of the intricate pieces of the autism puzzle, with two studies that identify genes with important contributions to the disorder. One study pinpoints a gene region that may account for as many as 15 percent of autism cases, while another study identifies missing or duplicated stretches of DNA along two crucial gene pathways. Significantly, both studies detected genes
Fussy Baby? Linking Genes, Brain And Behavior In Children It comes as no surprise that some babies are more difficult to soothe than others but frustrated parents may be relieved to know that this is not necessarily an indication of their parenting skills. According to a new report in Psychological Science children's temperament may be due in part to a combination of a certain gene and a specific pattern of brain activity.
Active Genes Discovered In The Developing Mammal Brain New information about the genes involved in a mammal's early brain development, including those that contribute to neurological disorders such as autism and mental retardation, has been discovered. The study is the first to use high-throughput sequencing to uncover active genes in developing brains, and it may be the best evidence yet for the activity in the brain of a large number of genes.
Neuroscientists reveal new links that regulate brain electrical activity Researchers have made a major breakthrough in our understanding of nerve impulse generation within the brain. Brain cells communicate with each other by firing electrical impulses, which in turn rely upon special ion channels that are positioned at strategic locations in their membranes.
