how does excitatory neurotransmitters impact the behavior of the individual?
Weegy: Neurotransmitters are chemicals located and released in the brain to allow an impulse from one nerve cell to pass to another nerve cell. [ Some common neurotransmitters are acetylcholine, norepinephrine, dopamine, serotonin and gamma aminobutyric acid (GABA). Acetylcholine and norepinephrine are excitatory neurotransmitters while dopamine, serotonin, and GABA are inhibitory neurotransmitters. Each neurotransmitter can directly or indirectly influence neurons in a specific portion of the brain, thereby affecting behavior. Any abnormal level in neurotransmitters can lead to mental disorders. Serotonin is known contributor to feeling and well being, these include the regulation of mood, appetite, sleep, as well as muscle contraction and some functions including in memory and learning. Norepinephrine is found in parts of the brain called amygdala, where attention and responses are controlled. Any imbalance in serotonin and norepinephrine activity can lead to depression symptoms as well as anxiety disorders. Impairment of dopamine containing neurons can lead to schizophrenia, Attention-deficit and hyperactivity disorder. Each neurotransmitter is found in specific parts of the brain and their job is to transmit messages from one nerve cell to another. If their normal activity level is changed by drugs such as alcohol, cocaine or marijuana, this can affect mood and behavior of a person. ] (More)

What neurotransmitter(s) is believed to function abnormally in seizures, and how this impacts on the behavior of a person?
Weegy: Neurotransmitters are essential chemical messengers used by neurons in the brain to send and receive electro-chemical signals within the brain and facilitate communication with all the other organ systems in the body. [ [ These powerful neurochemicals are responsible for regulating practically all functions in life, such as cognitive, physical and mental performance, sleep cycle, weight, pain perception and response and our emotional states. Essentially they are the communication system of the mind, body and nervous system. To get a good picture in your head of what this means, you can think of your telephone service. A complex web of interconnections that allows communication to take place. Neurotransmitters literally govern every system in the body either directly or indirectly. ] ] (More)
