Brain wave- an electric impulse in the brain
Approximately 12 million children under the age of 18 have mental disorders. |--- WOW ---|
THE BRAINThe brain is an incredibly complex organ.
It makes up only 2 percent of our body weight, but it consumes 20 percent of the oxygen we breathe and 20 percent of the energy we take in.
It controls virtually everything we as humans experience, including movement, sensing our environment, regulating our involuntary body processes such as breathing, and controlling our emotions. Hundreds of thousands of chemical reactions occur every second in the brain; those reactions underlie the thoughts, actions, and behaviors with which we respond to environmental stimuli.
In short, the brain dictates the internal processes and behaviors that allow us to survive.
How does the brain take in all this information, process it, and cause a response? The basic functional unit of the brain is the neuron.
A neuron is a specialized cell that can produce different actions because of its precise connections with other neurons, sensory receptors, and muscle cells.
A typical neuron has four structurally and functionally defined regions: the cell body, dendrites, axons, and the axon terminals.
