Brain and Behavior David Eagleman Jonathan Downar Chapter Outline The Cells of the Brain Synaptic Transmission Chemical Signaling in the Brain Spikes Electrical Signaling in the Brain What Do Spikes Mean The Neural Code. A new approach to Artificial Intelligence. Why is creating an . Artifical. Bran difficult?. There are HUGE differences between brain architecture and computer architecture. The difficulty to emulate one system on another system increases linear with the number of differences in architecture between the two systems.. Understanding:. Neurons transmit electrical impulses. The myelination of nerve fibers allows for salutatory conduction. Neurons pump sodium and potassium ions across their membranes to generate a resting potential . Neurons . do. not . undergo mitosis!. The . Nervous System can transmit impulses as fast as 100 meters per . second!. If . we lined up all the neurons in our body it would be around 600 miles . long!. What a lot of nerve!. There are about 100,000,000,000 neurons in an adult human.. These form 10,000,000,000,000 synapses, or connections. They represent 2. % . of the body’s weight. , 0.04-0.07% . cells and .

The nervous system enables the body to respond to continuous changes in its external and internal environment. It controls and integrates the functional activities of the organs and organ systems. . Ms. . Carmelitano. Introduction. Neurons are the building blocks of behavior. The 10 to 100 billion neurons make about 13 trillion connections with each other over the synapses. Essential Question: How do messages cross the synapses?. Section 1 – Functions & Divisions of the Nervous System (pp. 386-387). This is your brain…. The Nervous System.
