For a neuron to be polarized‚ it is by maintaining excess of sodium ions on the outside of the cell and excess potassium ions on the inner part of the cell. A volume of sodium ions and potassium ions usually leaks through its channel but the sodium ions and potassium ions pumps on the membrane that restores the (k+) back inside and Na+ back outside.

Exceeding the threshold depolarization at the trigger zone DECREASES the likelihood of generation of action potential. 2. Action potential amplitude: DOES NOT CHANGE with distance 3. Increasing frequency of stimulation to the trigger zone: DOES NOT increase the production of action potentials.

Neurotransmitters are brain chemicals that transmit information throughout our brain and body. They transmit nerve signals electrically and chemically between neurons. Neurotransmitters can affect mood‚ sleep‚ concentration and weight. The two kinds of neurotransmitters are: inhibitory and excitatory which‚ respectively‚ calm and stimulate the brain. Dopamine is an inhibitory neurotransmitter so when dopamine reaches the receptor sites‚ it blocks the neuron from firing. Dopamine is produced in multiple

Neurotransmitters Dr. C. George Boeree Neurotransmitters are the chemicals which allow the transmission of signals from one neuron to the next across synapses. They are also found at the axon endings of motor neurons‚ where they stimulate the muscle fibers. And they and their close relatives are produced by some glands such as the pituitary and the adrenal glands. In this chapter‚ we will review some of the most significant neurotransmitters.
