Updated Budget Projections: 2016 to 2026 March 24, 2016 CBO projects a $534 billion deficit in fiscal year 2016, about $100 billion more than in 2015. If current laws generally remained unchanged, the deficit would increase from 2.9 percent to 4.9 percent of GDP over the next decade.

The neuron (nerve cell) is the fundamental unit of the nervous system. The basic purpose of a neuron is to receive incoming information and, based upon that information, send a signal to other neurons, muscles, or glands. Neurons are designed to rapidly send signals across physiologically long distances. They do this using electrical signals called nerve impulses or action potentials. When a nerve impulse reaches the end of a neuron, it triggers the release of a chemical, or neurotransmitter. The neurotransmitter travels rapidly across the short gap between cells (the synapse) and acts to signal the adjacent cell.
