Neurotransmitters- are chemical messengers that allow signals to cross synapses to
transmit information from a nerve cell or neuron to a target cell. Nerve transmitters
coordinate behavor by stiulating an action or inhibiting an impulse. Example of
neurotransmitters: dopamine. Used by the brain to help regulate breathing,
heartbeat, and digestion. It can also affect concentration, sleep, and mood.
Neurons- have many sizes, lengths, and shapes that determine their function based
on where they are in the brain; and are the cells of chemical communication in the
brain. Human brains are comprised of tens of billions of neurons, and each is linked
to thousands of other neurons. Thus, the brain has trillions of specialized
connections known as synapses. * The anatomically addressed brain is thus a
complex wiring diagram, ferrying electrical impulses to wherever the “wire” is
plugged in (synapses). **When neurons malfunction behavioral symptoms may
occur. When drugs alter neuronal function, behavioral symptoms may be relieved,
worsened, or produced. Neurons are some of the longest-lived cells in your body;
neurons are irreplaceable, and neurons have huge appetites (glucose and appetites).
Neurons transit signals when stimulated by sensory input or triggered by
neighboring neurons.
