Wernicke's area is a part of the human brain that forms part of the cortex, on the left posterior section of the superior temporal gyrus, posterior to the primary auditory cortex, on the temporo-parietal junction (part of the brain where the temporal lobe and parietal lobe meet).

The brain tissue surrounding the ventricles is far from homogeneous, but can be separated into a number of connected but distinct parts. It is dominated by the massive cerebrum, or forebrain, divided neatly down its mid-line into two almost mirror-image halves, linked by a massive band of nerves, the corpus callosum. Below the cerebral hemispheres lie the mid- and hind-brains. For the first 3-4 mm below the wrinkled surface of the cerebrum the tissue is coloured pinkish grey, forming the cortex (meaning “bark”); below that, it is yellowish white. The colour of the cortex is due to its extremely rich blood supply—fully 20 per cent of circulating blood goes to supply the brain. By contrast the “white matter” is so because of the fatty sheaths, composed largely of myelin, which insulate the nerves packed inside. The geography of the cerebral cortex, defined by its ridges and clefts (sulci and gyri) provides a distinction between left and right, frontal and occipital lobes. The regions towards the mid-line are medial, towards the sides temporal, the top, dorsal, and the bottom, ventral.\n\nBehind the cerebrum lies the even more wrinkled and folded cerebellum (“little brain”) covered with its own cortex. Visible as the brain is dissected are a number of distinct structures named by the anatomists after their fancied resemblance to other natural forms—the hippocampus (seahorse), amygdala (almond), pons (bridge), medulla, and many more. Running down from the medulla and through the spine is the spinal cord, carrying nerves to (afferent) and from (efferent) the brain itself. Nerves to and from the eyes (optic), nose (olfactory), and also cranial nerves to other regions of the head run directly into the brain, not via the spinal cord. Together, brain and spinal cord form the central nervous system (CNS), to distinguish them from the nerves that connect the brain and cord with the rest of the body, called the peripheral nervous system. Because of the bilateral symmetry of the brain, each of the structures within it seemed to the early anatomists to be duplicated, one to the left and one to the right. The exception seemed to be the pineal gland, located in the centre of the brain, and it was in part because of this that Descartes, whose dualist philosophy firmly separated the human soul from the mere clockwork processes that ran the rest of the body, decided that the pineal must be the site at which the soul or mind interacted with and drove the body forward. Non-human animals, which were believed not to possess souls, he saw as entirely machine-like.\nThe current view of the brain is of an organ composed of a large number of substructures, each densely packed with neurons and their surrounding glia. Within each nucleus, and within the cerebral and cerebellar cortices, neurons are of three general types: some receive inputs from either sense organs or other brain regions; others (projection or pyramidal neurons) transmit signals out of the region, down long axons to other brain regions or, via the spinal cord or cranial nerves to the periphery. The third and much the most numerous class are the spiny or stellate interneurons, which communicate only within a particular nucleus or cortex, either with one another or with the afferent and efferent neurons.\n\nFor modern localizers, these different substructures are regarded as “centres” for particular brain functions. Of particular importance are a group of connected nuclei including the hypothalamus, hippocampus, some nuclei of the thalamus, and the amygdala, sometimes grouped together as the limbic system. These centres are particularly relevant in the context of emotion, sexual drive, hunger, and thirst, and damage to them can have profound effects. The hypothalamus also has direct neural connections with the pituitary gland at the base of the brain, the source for many important regulatory hormones, and hypothalamic-pituitary feedback processes provide a key site for

I know about the God spots in the brain. At first they thought it was only in the temporal lobe, but  now they found a few other spots in the brain. \n\n     I will have to do some research on the God gene. \n\n A group of neuroscientists at the University of California at San Diego has identified a region of the human brain that appears to be linked to thoughts of spiritual matters and prayer. Their findings tentatively suggest that we as a species are genetically programmed to believe in God.\n\nThe researchers came upon these cerebral revelations in the course of studying the brain patterns of certain people with epilepsy. Epileptics who suffer a particular type of seizure are often intensely religious, and are known to report an unusual number of spiritually-oriented visions and obsessions. Measurements of electrical activity in the brains of test subjects indicated a specific neural center in the temporal lobe that flared up at times when the subjects thought about God. This same area was also a common focal point overloaded with electrical discharges during their epileptic seizures.\n\nCould this heretofore unidentified part of the brain -- nicknamed the "God module" -- actually be some sort of physiological seat of religious belief? The scientists who discovered it believe it might be. They have performed a further study comparing epileptic subjects with different groups of non-epileptics -- a random group of average people, as well as individuals who characterized themselves as extremely religious. The electrical brain activity of the subjects was recorded while they were shown a series of words, and the God module zones of the epileptics and the religious group exhibited similar responses to words involving God and faith. No word yet on whether the brains of atheists and agnostics might flatline the monitors, but the parallel results among the strong believers are considered impressive.

Brain is the portion of the vertebrate central nervous system that is enclosed within the cranium, continuous with the spinal cord, and composed of gray matter and white matter. It is the primary center for the regulation and control of bodily activities, receiving and interpreting sensory impulses, and transmitting information to the muscles and body organs. It is also the seat of consciousness, thought, memory, and emotion. \nA functionally similar portion of the invertebrate nervous system. \n\nIntellectual ability; mind: a dull brain; a quick brain. \n\nMind the capacity of thinking, reasoning, and acquiring and applying knowledge. Mind refers broadly to the capacities for thought, perception, memory, and decision: “No passion so effectually robs the mind of all its powers of acting and reasoning as fear” (Edmund Burke). Intellect stresses knowing, thinking, and understanding: “Opinion is ultimately determined by the feelings, and not by the intellect” (Herbert Spencer). Intelligence implies solving problems, learning from experience, and reasoning abstractly: “The world of the future will be an ever more demanding struggle against the limitations of our intelligence” (Norbert Wiener). Brain suggests strength of intellect: We racked our brains to find a solution. Wit stresses quickness of intelligence or facility of comprehension: “There is no such whetstone, to sharpen a good wit and encourage a will to learning, as is praise” (Roger Ascham). Reason, the capacity for logical, rational, and analytic thought, embraces comprehending, evaluating, and drawing conclusions: “Since I have had the full use of my reason, nobody has ever heard me laugh” (Earl of Chesterfield). The human consciousness that originates in the brain and is manifested especially in thought, perception, emotion, will, memory, and imagination. \nThe collective conscious and unconscious processes in a sentient organism that direct and influence mental and physical behavior. \nThe principle of intelligence; the spirit of consciousness regarded as an aspect of reality. \nThe faculty of thinking, reasoning, and applying knowledge

The human brain. Look at everything around you, it was created by the human brain. Cars, buildings, nuclear weapons, etc. were created by the human brain. Everything that you feel emotionally, all of your passion, motivation, and "spirit" is the direct result of your brain.

Human brain - our capability to think, problem solve and communicate.\n\nIf you compare human brain volume with other animals, we have the biggest (and most complex/developed) brain in relation to the body mass.  \n\nIt is our brain that gave us a distinct advantage to survive natural selection.  We have never been the strongest animal, but we're the smartest and most resourceful by far.  If not for our ability to adapt and invent, we’d have been hunt to extinction by other stronger carnivores.

We have absolutely no idea what the biological mechanism is, where the seat of conciousness is, not what other animals may or may not possess it. If anyone tells you otherwise, they are lying-We don't even understand the biological basis of simple learning and behaviour, and cannot, from a complete three dimensional diagram of a 1000-neuron worm brain, tell you anything about it's behaviour. We are as close to understanding the most profound and complex functions of the brain as a monkey is to learning computer programming. I both teach and research in this area, and I guarantee you that we are still at the most basic level of understanding brain function.

Function\nThe superior temporal gyrus includes an area (within the Sylvian fissure) where auditory signals from the cochlea (relayed via several subcortical nuclei) first reach the cerebral cortex. This part of the cortex (primary auditory cortex) is involved in hearing. Adjacent areas in the superior, posterior and lateral parts of the temporal lobes are involved in high-level auditory processing. In humans this includes speech, for which the left temporal lobe in particular seems to be specialized. Wernicke's area which spans the region between temporal and parietal lobes plays a key role (in tandem with Broca's area, which is in the frontal lobe). The functions of the left temporal lobe are not limited to low-level perception but extend to comprehension, naming, verbal memory and other language functions.\n\nThe underside (ventral) part of the temporal cortices appear to be involved in high-level visual processing of complex stimuli such as faces (fusiform gyrus) and scenes (parahippocampal gyrus). Anterior parts of this ventral stream for visual processing are involved in object perception and recognition.\n\nThe medial temporal lobes (near the sagittal plane that divides left and right cerebral hemispheres) are thought to be involved in episodic/declarative memory. Deep inside the medial temporal lobes, the hippocampi seem to be particularly important for memory function, and they also seem to play a part in controlling spatial behavior

The cerebellum (Latin: "little brain") is a region of the brain that plays an important role in the integration of sensory perception and motor output. Many neural pathways link the cerebellum with the motor cortex—which sends information to the muscles causing them to move—and the spinocerebellar tract—which provides feedback on the position of the body in space (proprioception). The cerebellum integrates these two functions, using the constant feedback on body position to fine-tune motor movements.\n\nIts location is shown here:\nhttp://en.wikipedia.org/wiki/Cerebellum
