The localizationist model attempts to classify the aphasia by major characteristics and then link these to areas of the brain in which the damage has been caused.

It has been claimed that in reading Arabic, the human brain processes Arabic script differently than alphabets, using mainly the left hemisphere, not both.

Captopril is also the only ACE inhibitor which is capable of passing through the blood – brain barrier, although the significance of this characteristic has not been shown to have any positive clinical effects.

" Continuous use of neuroleptics has been shown to decrease the total brain volume by 10 % in macaque monkeys.

For example, one meta-analysis reviewing human brain lesions has shown a left hemisphere bias during tool usage.

Some scientists believe it has to do with a kind of neural map that the brain has of the body, which sends information to the rest of the brain about limbs regardless of their existence.

It has been hypothesized that the portion of the brain responsible for processing stimulation from amputated limbs, being deprived of input, expands into the surrounding brain, ( Phantoms in the Brain: V. S. Ramachandran and Sandra Blakeslee ) such that an individual who has had an arm amputated will experience unexplained pressure or movement on his face or head.

The operations of individual brain cells are now understood in considerable detail, but the way they cooperate in ensembles of millions has been very difficult to decipher.

The human brain has been estimated to contain approximately 100 trillion synapses ; even the brain of a fruit fly contains several million.

It has not been definitively established whether the existence of these brainless species indicates that the earliest bilaterians lacked a brain, or whether their ancestors evolved in a way that led to the disappearance of a previously existing brain structure.

The relationship between brain size, body size and other variables has been studied across a wide range of vertebrate species.

The brain of a shark shows the basic components in a straightforward way, but in teleost fishes ( the great majority of existing fish species ), the forebrain has become " everted ", like a sock turned inside out.

On average, a mammal has a brain roughly twice as large as that of a bird of the same body size, and ten times as large as that of a reptile of the same body size.

Research has suggested that the sensations are genital orgasms caused by nipple stimulation, and may also be directly linked to " the genital area of the brain ".

It has made progress in understanding how damage to particular areas of the brain affect cognition, and it has helped to uncover the root causes and results of specific dysfunction, such as dyslexia, anopia, and hemispatial neglect.

Searle himself was vague about what extra ingredients it would take to make a machine conscious: all he proposed was that what was needed was " causal powers " of the sort that the brain has and that computers lack.

He suggested that the interaction between these two domains occurs inside the brain, perhaps in a small midline structure called the pineal gland.

The point of interaction between the two are at the pineal gland in the brain.

Many formulations have forms of fluoride attached to assist in permeating the blood – brain barrier, which is suspected as a factor in pineal gland effects.

First, the soul is unitary, and unlike many areas of the brain the pineal gland appeared to be unitary ( though subsequent microscopic inspection has revealed it is formed of two hemispheres ).

They are created by an abnormal and uncontrolled cell division, usually in the brain itself, but also in lymphatic tissue, in blood vessels, in the cranial nerves, in the brain envelopes ( meninges ), skull, pituitary gland, or pineal gland.

The pineal gland secretes the hormone melatonin " directly into the systemic circulation ", thus melatonin is not affected by the blood – brain barrier.

Technically, Kundalini energy is understood as being sparked during yogic breathing when prana and apana blends at the 3rd chakra ( naval center ) at which point it initially drops down to the 1st and 2nd chakras before traveling up to the spine to the higher centers of the brain to activate the golden cord-the connection between the pituitary and pineal glands-and penetrate the 7 chakras.

In his letter to Elisabeth of Bohemia, Princess Palatine, he suggested that animal spirits interacted with the body through the pineal gland, a small gland in the centre of the brain, between the two hemispheres.

Blavatsky and Rick Strassman, have suggested that the third eye is in fact the partially dormant pineal gland, which resides between the two hemispheres of the brain.

The pineal gland ( also called the pineal body, epiphysis cerebri, epiphysis, conarium or the " third eye ") is a small endocrine gland in the vertebrate brain.

Melatonin is secreted into the blood by the pineal gland in the brain.

Melatonin, produced in the pineal gland which is outside of the blood – brain barrier, acts as an endocrine hormone since it is released into the blood.

In humans, melatonin is produced by the pineal gland, a small endocrine gland located in the center of the brain but outside the blood – brain barrier.

Descartes focused much of his anatomical experimentation on the brain, paying specific attention to the pineal gland – which he argued was the actual “ seat of the soul ”.

Descartes, for example, suggested that the pineal gland, a midline unpaired structure in the brain of many organisms, was the point of contact between mind and body.

This is also true of most brain abnormalities, though there are exceptions such as a calcified tumour ( e. g. meningioma, craniopharyngioma, some types of glioma ); whilst calcification in such normal structures as the pineal body, the choroid plexuses, or large brain arteries may indirectly give important clues to the presence of structural disease in the brain itself.

In non-mammalian vertebrates, melanopsin is found in a wider subset of retinal cells, as well as in photosensitive structures outside the retina such as the iris muscle of the eye, deep brain regions, the pineal gland, and the skin.

The epithalamus is a ( dorsal ) posterior segment of the diencephalon ( a segment in the middle of the brain also containing the hypothalamus and the thalamus ) which includes the habenula and their interconnecting fibers the habenular commissure, the stria medullaris and the pineal body.

Dr Strassman's studies aimed to investigate the effects of N, N-dimethyltryptamine ( DMT ), a powerful entheogen, or psychedelic, that he hypothesizes is produced by the human brain in the pineal gland.

The brain structure that is the center of most neurobiological events associated with fear is the amygdala, located behind the pituitary gland.

A low TSH level typically indicates that the pituitary gland is being inhibited or " instructed " by the brain to cut back on stimulating the thyroid gland, having sensed increased levels of T < sub > 4 </ sub > and / or T < sub > 3 </ sub > in the blood.

TSH is a hormone made by the pituitary gland in the brain that tells the thyroid gland how much hormone to make.

* Brain: A small outgrowth of the ventral wall of the embryo brain from which the pars nervosa ( the posterior lobe ) of the pituitary gland develops is also called the infundibulum.

Descartes believed inputs are passed on by the sensory organs to the Pineal gland | epiphysis in the brain and from there to the immaterial spirit.

Malpighi also studied the anatomy of the brain and concluded that this organ is a gland.

Phobias are more often than not linked to the amygdala, an area of the brain located behind the pituitary gland in the limbic lobe.

An endocrine gland is attached to the ventral posterior surface of the brain, and appears to be involved in reproductive activity.

Thus, the endocrine system is a critical focus of psychopharmacology because 1 ) drugs can alter the secretion of many hormones ; 2 ) hormones may alter the behavioral responses to drugs ; 3 ) hormones themselves sometimes have psychoactive properties ; and 4 ) the secretion of some hormones, especially those dependent on the pituitary gland, is controlled by neurotransmitter systems in the brain.

In the brain, tissues with melanin include the medulla and zona reticularis of the adrenal gland, and pigment-bearing neurons within areas of the brainstem, such as the locus coeruleus and the substantia nigra.

* Pituitary gland – an endocrine gland at the base of the brain.

The pituitary fossa, in which the pituitary gland sits, is situated in the sphenoid bone in the middle cranial fossa at the base of the brain.
