Aerobic Exercise: Effects: Cognitive Function Effects "In contrast, arithmetic stimulated brain activity
in both the left and right hemispheres of the frontal lobe" The Observer International: Computer Games Stunt Teen
Brains "[Kawashima] compared brain activity in children
playing Nintendo games with those doing an exercise called the Kraepelin
test, which involves adding single-digit numbers continuously for 30
minutes… Studies confirmed the high
level of brain activity involved in carrying out simple addition and
subtraction and that this activity was particularly pronounced in the frontal
lobe, in both the left and right hemispheres. Though it is often thought
that only the left hemisphere is active for mathematical work and that the
right hemisphere is stimulated by more creative thinking, the professor found
that arithmetic produced a high level of activity in both hemispheres. In subsequent studies,
Kawashima established that arithmetic exercises also stimulate more brain
activity than listening to music or listening to reading." The Observer International: Computer Games Stunt Teen

action.]." Encyclopedia.com: catecholamine ·

norepinephrine [noradrenaline], which are also hormones, are secreted by the adrenal
medulla, and ·

catecholamines include such compounds as ·
Epinephrine,

Topics: Sleep Deprivation: Adrenaline Note: Norepinephrine is also
known as noradrenaline. What is Norepinephrine? "A neurotransmitter in the catecholamine
family that mediates chemical communication in the
sympathetic nervous system [the part of the nervous system that mobilizes the body for
action.], a branch of the
autonomic nervous system [the nervous system that governs involuntary
actions.]." Encyclopedia.com: norepinephrine "Like other neurotransmitters, it is released at
synaptic nerve endings to transmit the signal from a nerve cell to other
cells." Encyclopedia.com: norepinephrine "Norepinephrine is almost identical in structure to
epinephrine [adrenaline], which is released into the bloodstream from the
adrenal medulla under sympathetic activation." Encyclopedia.com: norepinephrine Causes of Norepinephrine Secretion "It is stored in chromaffin granules in the adrenal
medulla, in much smaller amounts than epinephrine [adrenaline], and secreted
in response to hypotension and physical stress;" Stedman's Online Medical Dictionary, 27th Edition:
Noradrenaline Effects Heart Rate, Blood Pressure "The sympathetic nervous system functions in response to
short-term stress; hence norepinephrine and epinephrine increase the heart
rate as well as blood pressure." Encyclopedia.com: norepinephrine Other Effects "Other actions of norepinephrine include ·
Increased glycogenolysis (the conversion
of glycogen to glucose ) in the liver, ·
Increased lipolysis (the conversion
of fats to fatty acids; see fats and oils ) in adipose (fat) tissue, and ·
Relaxation of bronchial smooth
muscle to open up the air passages to the lungs. All of these actions represent a mobilization of the body's
resources in order to meet the stressful challenge—such a response is
often termed the 'flight or fight' syndrome." Encyclopedia.com: norepinephrine "In contrast to epinephrine it has little
effect on ·
Bronchial smooth muscle, ·
Metabolic processes, and ·
Cardiac output, but ·
Has strong vasoconstrictive effects [causes
a narrowing of an opening of a blood vessel, maintains or increases blood
pressure] and is used pharmacologically as a vasopressor [a
medication that raises blood pressure], primarily as the bitartrate salt. Stedman's Online Medical Dictionary, 27th Edition:

Brains Singing or "Stuttering is different from other disorders in
that individuals who stutter can become fluent, for instance, by
singing or reading aloud at the same time with another individual. We
measured their brain activity when they were stuttering and when they
were fluent. We then compared them to normal controls doing the same tasks.
First we had them read out loud--alone and stuttering. Then we had them
reading out loud with another person at the same time. When stutterers read
out loud with another person, they are almost completely fluent. We utilized
this technique [PET imaging] to see what changes [occur] in individuals who
stutter when they are fluent compared to when they are stuttering." Psychiatric Times: Speaking Freely "PT: We understand you traced stuttering to a spot in the
left caudate of the brain? Actually the left striatum, which includes the caudate.
We found that activity in this area tends to be low in individuals who
stutter, whether they are fluent or not. They're also low when they are
stuttering in the Broca's area, the Wernicke's area and associated
areas in the frontal lobe and portions of the cerebellum.
They are able to activate or normalize these areas when they are fluent by
speaking aloud with another person. When fluent, the cortical areas
increase to normal levels, but the striatum remains low. So it looks
like low functioning in the striatum is a trait marker. This suggests that induced fluency through reading aloud
with another person activates an alternate speech pathway.
However, we have to caution that this is just a preliminary study, although
we have built upon our earlier preliminary data with some unpublished
material which does confirm this. What's interesting, too, is that we've
recently completed an F-dopa PET study which measures the levels of
presynaptic dopamine in the brain. We postulate that individuals
who stutter may have high levels of dopamine activity. We know that
individuals with schizophrenia have low function of the striatum that
is increased with antipsychotic medicine. And we know from earlier
studies with haloperidol [Haldol] that stuttering is improved with
medications that block dopamine, but the side effects are just too great for
people to stay on it." Psychiatric Times: Speaking Freely Reading Along with an Audio Book · Look for audio books that are unabridged.

Arithmetical Exercises · "This amino acid
is the building block for the nerve chemicals dopamine, epinephrine
(adrenaline), and norepinephrine (noradrenaline). These three help regulate
levels of arousal and anxiety. · Stress depletes tyrosine
from the blood, which limits the amount available for manufacturing nerve
chemicals. · Supplements of tyrosine might
boost memory, but only when there is a deficit caused by stress or aging.
Whether supplements improve thinking ability in other people is unknown.

[a building block of serotonin], tyrosine is found in protein-rich foods.
Unlike tryptophan, tyrosine levels in the blood and brain rise when a person
consumes pure tyrosine or, to a lesser extent, eats a protein-rich meal. The
same processes that lower tryptophan levels-that is, high levels
of competing amino acids and no insulin-are the very
processes that favor tyrosine. Consequently, tyrosine and tryptophan are at
odds with one another (Page 16)" Book: Somer,
