Turn-ons and turn-offs for neurons reported
July 6th, 2007
Our brain consists of billions of nerve cells enabling to learn, remember and reason. Every time we think and experience, touch, smell or fear, millions of neurons in our brain becomes active. These nerve cells communicate with each other by chemical and electrical impulses to compute incoming sensory information and integrate it via distinct brain regions. With 20,000 - 25,000 genes in our genome, most also expressed in neurons, there is now little doubt that neurons respond to challenging environments by adjusting the expression of genes for appropriate brain functions. Stress, addiction, learning and disease are all believed to change neuronal gene expression by...
