2nd BRAIN IN THE HEART

                                           2^nd BRAIN IN THE HEART

Heart is an amazing organ. In an average life time it beats around 2.5 billion times and pumps 2000 gallons of blood per day roughly. It is the universal symbol of love.

Far more than a simple pump, as was once believed, the heart is now recognised by its own functional “BRAIN”.

Heart is the “intelligent force”behind the intuitive thoughts and feelings we all experience. In many cultures throughout history, heart has been considered the source of emotion, passion and wisdom. Also people used to feel that they experienced the feeling or sensation of love and other emotional states in the area of the heart. They used to mention the common quote-:

“My mind tells me to give, but my heart won’t let me”

What does the BIBLE say about the heart?

The word HEART is mentioned about 700 times in the BIBLE. It signifies a person’s will or desires. According to the Bible, a person’s heart reveals his true nature and motivation.

     BHAGAVAD –GITA says-

“I am the supersoul, situated within the heart of all living beings; I am the origin, the middle, and the end of all living beings” (lord Krishna, Bhagavad-Gita 10.20)

According to ISLAM, a clean heart means, “the heart of one that is pious, pure and free of sin, transgressions, hatred and Hasad (jealousy)”.

How & why the heart affects mental activity & emotional balance?

The heart is seen as the connection between the mind and the body, forming a bridge bn the two.

The heart communicates with the brain and the rest of the body in 3 ways.

1) Neurologically (thro’ transmission of nerve impulse)

2) Biochemically (thro’hormones and neurotransmitters)

3) Biophysically (thro’pressure waves)

In addition (4) thro’ electromagnetic field interaction)

NEUROLOGICAL COMMUNICATION

Recently scientists discovered that, the heart has its own independent nervous system-complex system referred to as the brain in the heart.

Dr.J.Andrew Armour in 1991, described the complex circuit in the heart contains around 40,000 neurons, called sensory neurites.information from the heart including feeling sensation is sent to the brain thro’ several afferents. These afferent Ns enter the brain at the area of medulla and into the higher centers of brain where they influence perception, decision making and other cognitive process.

COMMUNICATION VIA HORMONES

In addition to extensive neurological interactions with the brain and body, the heart also communicates with the brain and body biochemically, by way of the hormones it produces.

A hormone ANF(Atrial natriuretic factor) was isolated, in addition a cell type known as ICA-Intrinsic cardiac Adrenergic cell releases Nor epinephrine and dopamine. Heart also secretes oxytocin (love or bonding hormone)-in addition to its function in child birth and lactation, also involved in cognition,tolerance,adaptation,sexual and maternal behaviour, learning social cues.

BIOPHYSICAL INTERACTION

With every beat the heart generates a powerful pressure wave that travels rapidly thro’out the arteries must faster than the actual flow of blood. These waves of pressure create what we feel as pulse. The pressure waves can modulate brain activity and affect vital processes even at the cellular level.

HEART’S MAGNETIC FIELD

Research has also revealed that the heart communicates information to the brain and body via electromagnetic field. The heart’s magnetic component is about 500 times stronger than brain’s magnetic field and can be detected several feet away from the body with sensitive magnetometers. They have also found that one person’s brain waves can synchronize another person’s heart.

Not only a pumping machine.....also has a brain:

There are also new data suggesting that both heart and brain are involved in intuitive perception. Even more surprising was that the heart receives this intuitive information before the brain.

Heart begins to beat even before the brain is formed (in uterus), so it appears that heart truly holds primary status as the initiator of human life.

Is it better to listen to your heart or brain?

Follow your heart when making a decision about love or relationship. (But take your BRAIN with you)

Follow your brain during career planning, education or financial situations.

I WISH MY BRAIN HAD A CIRCUIT TO DIRECT MY HEART!!

Driving tips for learners

DRIVING TIPS FOR LEARNERS

Driving is not a competition;it doesn’t impress anybody if you drive fast in the wrong places.
Follow the rules of the road.drive like you own the car,not the road!
Drive at a safe following distance.do not tail gate.(practice of driving too close to the vehicle in front).
Aggressive driving (speeding,rapid acceleration and braking)can cause wastage of fuel.
Clutch pedal is not your footrest.avoid driving with your foot resting on the clutch pedal.
Distracted driving:
The mental turmoil may be in the form of visual,manual or cognitive.
Visual:taking your eyes off the road
Manual:taking your hands off the road
Cognitive:taking your mind off what you are doing.
Avoid using mobile phones;using hands free device is also not safer,bcz the cognitive workload causes the risk.
Drive safely and in a way that suits your ability and traffic conditions.HAPPY DRIVING!!

Happy New Year 2012

ADAM'S CURSE, IS IT WITH US TODAY?

ADAM’S CURSE, IS IT WITH US TODAY?
Biblical tradition tells the story of creation with man as the 1st sex, and woman the second, created from Adam’s rib.
Biology conveys a different tale for the evolution of sexes, however revealing that man, is the second sex not woman. Recent research evidences suggesting that man not only be the 2nd to arise, but the 1st to disappear.
‘Y’ in trouble
The human Y has lost 1393 of its 1438 original genes over the course of its existence. Researchers have found that, Y is degrading fast; losing genes at rate of 5 per million years and the Y will ‘self destruct’ within the next 10 million years.
Back 300 million years ago, we had no sex chromosomes, only ordinary autosomes.Then suddenly a chance mutation occurred in the ancestral Y, mutating the SOX3 to the SRY gene. The ancestral X retained the unmutated SOX3.And then sex chromosome emerged.
Between 80-300 million years ago, inversion took place in Y and the ultimate result is only 2 distal ends of X and Y remains identical known as pseudoautosomal regions. Men are basically genetically modified women. For males there is curse of the lone X.they have ended up with an array of inherited condition and diseases related to problem on the X chromosome.
What are the reasons for greater mutation in ‘Y’?
The Y chromosome is unique in human genome. It is pathetic little chromosome, gene poor, (few genes interspersed with lots of junk) prone to deletions and loss.
Human Y chromosome is passed exclusively through sperm, which undergo multiple cell division during gametogenesis each cell division provides opportunity for mutation, and sperms are stored in the highly oxidative environment of the testes which encourages further mutation. These are the reasons; put the Y at a risk of mutation greater than the rest of the genomes.
Will we have males?
Scientists have long been suspected that, y is deteriorating and could disappear entirely within the next 10 million years.
Will this be the end of evolution for humans?-if this happens it won’t be the end of males.instead, another gene takes over and new sex genes start evolving.
Will there be new sex chromosome evolution in humans?
May be it will happen in different ways in different population, and we will split in to 2 species.
But what happens if X takes another evolutionary direction and become asexual?
Unisex reproduction by females is one of the options for the survival of humanity .(Female eggs fertilized by nuclear X chromosome of another female and implanted by IVF method.Eventhough several vital genes must come from males for survival, certain Rodent species –male vole of Europe and country rat of Japan are living healthy ,have no Y and no SRY genes.
Hope for Y’s future:
Y chromosome palindromes- y has been secretly creating backup copies of its most important genes. These are stored in the DNA as mirror images or palindromes(which read the same forward and backwards)That means ,many of the genes on ‘Y’do occur as pairs-allowing the genes to repair themselves when they get damaged. Resent comparisons of the human and chimpanzee Y chromosomes show that the human y has not lost any genes since the divergence of humans and chimpanzees between 6-7 million years ago.
Conclusion
It has been predicted that ‘Y’ will continue to decay and lose genes. Before the ‘Y’has a chance to disappear completely, however humans will have already left the earth or perhaps they will have been brought to judgement day by the same god who created Adam in the 1st place.

PHYSIOLOGY TUTORIAL

Human aging can be stopped by adding telomerase: comment
We may think that, human aging can be stopped by adding telomerase but, telomerase causes cells to divide rapidly and uncontrollably. Such an excessive cellular proliferation may leads to cancerous growth. So you can’t expect telomerase to become the elixir of your youth.
At the ends of each chromosome is a non functional strand of DNA called telomere. It has been observed experimentally that telomeres shorten with each successive cell division. Shortened telomeres activate a mechanism that prevents further cell multiplication. When telomeres become too short, the cells die.
In 1965, Leonard Hay flick discovered the Hay flick limit-phenomenon-is a number of times a normal cell divide before the telomere reaches critical length.
Somatic cells can only divide around 30-50 times due to Hay flick effect. On the other hand germcells, stemcells and cancerous cells (considered immortal –in the sense that they can reproduce indefinitely) contain telomerase that prevents Hay flick limit. This enzyme extends the telomere of chromosome and prevents shortening of telomere.
