Biofeedback

order to control or altar behavior, a person must have information that is
available through the senses.
In biofeedback, the client obtains information about his
biological state from feedback from the sensors. Margolin and Kubic (1944)
conducted an early example of this kind of feedback. They used a subject's
amplified respiration and heart beat to induce a hypnotic induction. Even
though the subjects were not told to adjust these physiological functions,
the feedback of thei .....

leans more to the creative, the intuitive. It is concerned more with the
visual and emotional side of life.
Most people, if they thought about it, would identify more with
their left brain. In fact, many of us think we are our left brains. All
of that non-stop verbalization that goes on in our heads is the dominant
left brain talking to itself. Our culture- particularly our school system

The Human Immunodeficiency Virus And Mutations
.... of viruses in general, and how HIV infects the body.
Definition
HIV is the virus that causes AIDS. HIV is classified as a RNA
Retrovirus. A retrovirus uses RNA templates to produce DNA. For example,
within the core of HIV is a double molecule of ribonucleic acid, RNA.
When the virus invades a cell, this genetic material is replicated in the
form of DNA . But, in order to do so, HIV must first be able to produce a
particular enzyme that can construct a DNA molecule using an RNA templa .....

Prolonged Preservation Of The Heart Prior To Transplantation
.... the donor heart is ultimately
given to someone whose tissues do not match up as well, so there is a
greatly increased chance for rejection of the organ by the recipient. As
far as the man in Oregon goes, he will probably not receive a donor heart
before his own expires.
Currently, when a heart is being prepared for transplantation, it
is simply submerged in an isotonic saline ice bath in an attempt to stop
all metabolic activity of that heart. This cold submersion technique is
adequate for on .....

who may try to kill themselves. Child and adolescent psychiatrists
recommend that if one or more of these signs occurs, parents need to talk
to their child about their concerns and seek professional help when the

The local midwife called the daya, would show up to perform the operation.
In most cases two women members of the family would hold the girl by her
thighs to expose her genitals and to prevent struggling. Then the daya

Chicken. These foods can be obtained by driving up to a window to order

because the apple or corn is easily recognized and doe .....

behavior. The major purpose for this research was the adoption studies
