The Synapse shows how the synapse changes information from electrical to chemical and back to electrical signals. Toxins and Synapses shows how different chemicals affect the synapse, discussing how animals and plants utilize toxins for protection.

Science - Biology - Neuroscience. "Over the past several years, scientists have looked deeper into how brains age and confirmed that they continue to develop through and beyond middle age. " "Many longheld views, including the one that 40 percent of brain cells are lost, have been overturned.

What is stuffed into your head may not have vanished but has simply been squirreled away in the folds of your neurons. " "Recently, researchers have found even more positive news. The brain, as it traverses middle age, gets better at recognizing the central idea, the big picture. If kept in good shape, the brain can continue to build pathways that help its owner recognize patterns and, as a consequence, see significance and even solutions much faster than a young person can.

Brain, Brain Information, Facts, News, Photos. Making sense of the brain's mind-boggling complexity isn't easy. What we do know is that it's the organ that makes us human, giving people the capacity for art, language, moral judgments, and rational thought. It's also responsible for each individual's personality, memories, movements, and how we sense the world. All this comes from a jellylike mass of fat and protein weighing about 3 pounds (1.4 kilograms). It is, nevertheless, one of the body's biggest organs, consisting of some 100 billion nerve cells that not only put together thoughts and highly coordinated physical actions but regulate our unconscious body processes, such as digestion and breathing.

The brain's nerve cells are known as neurons, which make up the organ's so-called "gray matter. " The cerebrum is the largest part of the brain, accounting for 85 percent of the organ's weight. The cerebrum has two halves, or hemispheres. Movement and Balance. Public Education & Outreach. Genes to Cognition Online.
