Do you see any relation between the three terms
Lets go back to heart again
Heart is full of
blood also it is full of feelings. Blood as we know the elixir of life after
water . It ischemical( biological) substance , and there are a lot of chemical
reactions to purify blood
Can we say that feelings are the same? for physical feelings like touch , this
is controlled throughnervous system. There are chemical materials in nerve
endings which control these feelings.But emotional feelings like fear,
anger , love ,etc
Look..!
If I tell you now that there a snake under
your table
I
can hear your heart beats very loud .! This is a normal
physiological reaction which controlled
through
some chemical
materials like adrenaline which increases heart rate
But if you always checking bed before sleep for snakes many times in one night , this is may be a
pathological one , looks like some kind of obsession. May
be you are in need to see your

It is a normal part of life . It is also emotional response to failure to achieve or maintain values Depression is due to imbalance of certain neurotransmitters which are chemicals in brain that transmit messages between nerve cells like serotonin and norepiephrine.Recently I attend psychiatry conference one of speaker was Prof. Ahmed Okasha The famous psychiatrist in The Middle East ,He said that Depression disorders of the human race. Ancient Egyptians six thousands years ago recognized depression and is one of the most ancient and common located it in the heart as shown in Eber's papyrus. WHO report year 2000 showed that every year there is one million suicides and 70% are suffering from depression . untreated major depression is a risk factor in developing coronary artery disease through the influence of stress and subsequent increased sympathetic tone

tell us about subjective feelings

The Emotional Brain
you are walking through the woods,and you see a coiled shape lying across you path.Instantly--before
you even think ''a snake!' --you brain begins to respond fearfully.Fear is an ancient emotionthat is involved in a number of mental disorders, say neuroscientist Joseph leDoux,Ph.D.,of New York University. His research and that of other scientist ,reported at the 24th Mathilde Solowey lecture in the Neurosciences at the National Institutes of Health on May 8,1997,has shown that the fear response has been tightly conserved in evolution , and probably follows much the same pattern in humans and other vertebrates
According to LeDoux,he and others are making progress in tracing the brain circuitry underlying the fear response.Research attention is now focused on the amygdala, a small almond-shaped structure deep inside the brain. A portion of the amygdala known as the lateral nucleus appears to play a key a role in fear conditioning -- an experimental procedure in which an animal--is taught to fear a harmless stimulus such as a sound tone. The conditioning is accomplished by pairing the tone with a mild electrical shock to the animal's foot .After a few times 'the animal comes to exhibit defensive responses whenever it hears the tone. These response include freezing(remainig motionless)and elevation of blood pressure
Can
we control our feelings
