brain states (release of serotonin and acetylcholine) have direct interaction with

diagnosis, and treatment of biochemical disorders of the brain the identity theory
has a strong case towards becoming reality.
Reductive materialism is known to be the reducing of mental activity into

automatically thinking when we here a sound, “it is waves traveling through air”,

“…the correct account of human-behavior-and-its-causes must reside in the
physical neurosciences” (MR324). Neurosciences and cognitive psychology
have been used together to explain brain states and mental states correlation.
“And those behavior-controlling internal operations are precisely what the

the brain has helped to draw this conclusion. Biochemical changes in the brain
of low levels of the chemical serotonin. Serotonin is a chemical in the brain that
between neurons. This brain state simultaneously affects the mental state or
behavior of a person who shows signs of depression. Such signs are inability to
fall asleep at night, frequent panic attacks, loss of concentration, and thoughts of
suicide or even attempted suicide.
Depression has also been linked with the low chemical release of the
neurotransmitter (chemical messenger) acetylcholine in the brain, which affects
memory capabilities in the mental state. These chemical releases can be
controlled with the aid of medication which alter the releases of these chemicals
serotonin and acetylcholine.
Medication such as Zoloft, Imipramine, Xanax and Clonopin help to alter
the brain states. Once the medication has taken effect and the brain states are
under control, the mental states (thoughts) have been altered as well. It is very
hard to explain without using some doctor’s DSM-IV book but the effects the
brain/neural transmitters have on the mental states of a person are in fact the
same. The thought’s under the mental state are changed solely because of the
Concentration levels have increased and a calmness has overcome the fear and
guilt in the mental states brought on by the brain state’s biochemical releases.
Another form of a brain state-controlling device is an electronic device
known as a transcutaneous electronic nerve stimulator. This is used to control
the mental states of pain. It sends electronic currents to the brain which in turn
send pain-inhibitors affecting the mental states. Once again this shows that “our
behavior appears to have its basic causes in neural activity” (TL325).
mental phenomena into physical phenomena, and vice versa making them the
same. This identity theory holds much ground in the psychological and
physiological forms as well. The example of depression is just one of many
claims that can be taken into consideration for the plausibility of the identity
theory. This brain disorder was used because of the personal involvement that I
have with it. Mental and brain states are one and in the same idea due to the

changing thoughts and behavior.
