Largely unconscious drives.

The drive channel initially learned by recording context. That was when you first learned to drive a car. Asrepparttar mind learned, combinations of contextual memories were encoded intorepparttar 140663 memories of drive channel neurons. Overrepparttar 140664 years, millions more contexts would be added. Shortcuts, early lane changes, responses to traffic snarls. Becauserepparttar 140665 channel neurons remembered, it was no longer necessary to highlight a landmark through attention. Increased firing was not needed to indicate context. Normal perceptions were adequate. The channel remembered and managed habitual activities. The studies supportedrepparttar 140666 view of a drive channel which acted through learned memories. But those memories had inherited components also. Those components also responded to feelings and emotions.

The historic basis of drives.

Purposeful drives had antecedents fromrepparttar 140667 beginnings of life. The Hydra was a primeval example of such a mechanism. It was a branched tubular animal. A netlike arrangement of neurons was interposed between its outside and its internal digestive cavity. A stimulus applied to any part of its body resulted in contraction or bending of its tubular body and its tentacles. The Hydra moved about with this simple nerve net, varied its length and used its tentacles to push food particles into its mouth. Occasional strong contractions ofrepparttar 140668 whole animal served to expel indigestible material fromrepparttar 140669 same orifice. Fromrepparttar 140670 beginnings of history, nature had devised ongoing drives, which enabled essential activities - to move about, swallow, or expel food. Across millions of years, more sophisticated feelings and emotions developed. Inherited memories generated a far wider range of drives to meetrepparttar 140671 needs of these emotions. Drives to teachrepparttar 140672 young, to lie inrepparttar 140673 grass, or to play onrepparttar 140674 field. Butrepparttar 140675 essentials remained. Drives to seek out and accept, or to avoid and escape.

The agreeable and disagreeable quality.

Medical texts reported thatrepparttar 140676 pleasure emotion was triggered fromrepparttar 140677 septal areas ofrepparttar 140678 brain for rats. The animals were observed when they were able to self stimulate themselves, by pressing a lever, through electrodes implanted inrepparttar 140679 septal area. They continued pressingrepparttar 140680 lever till they were exhausted, preferringrepparttar 140681 effect of stimulation to normally pleasurable activities such as consuming food. The pleasure emotion impelledrepparttar 140682 animal to repeatedly seek that stimulus. Onrepparttar 140683 other hand, pain was felt in two waves, separated by an interval of a few tenths of a second. The first was sharp and localized. The second wave was diffuse and still more disagreeable. So, also, after an operation called lobotomy,repparttar 140684 presence of pain was no longer distressing torepparttar 140685 patient who would say thatrepparttar 140686 pain was still there, but it did not “hurt.” Pain was divided into a sensation and a disagreeable element. That element was, in reality, a drive to avoidrepparttar 140687 stimulus.

Pleasant and unpleasant drives.

The primitive Hydra, moved about, swallowed, or spewed out food. Its drives worked to approach, accept, reject, or escape. Millenniums later,repparttar 140688 control systems were more sophisticated. But, humans traveledrepparttar 140689 seas, enjoyed delicious meals and occasionally became sea sick. Pleasant emotions generated a drive to approach and accept. The rat kept pressingrepparttar 140690 lever. Such emotions made you feel good. Unpleasant emotions generated a drive to escape, or rejectrepparttar 140691 stimulus. The second wave of pain was a drive triggered by cortical recognition of pain. That feeling triggered a drive to escape. That drive was disagreeable. It made you want to run away. Whenrepparttar 140692 drive was disconnected in lobotomy, pain became just a sensation. Drives affected peace of mind. The IA concept of a drive channel explains those subtle attributes of pain and pleasure.

Abraham Thomas is the author of The Intuitive Algorithm, a book, which suggests that intuition is a pattern recognition algorithm. The ebook version is available at www.intuition.co.in. The book may be purchased only in India. The website, provides a free movie and a walk through to explain the ideas.
