The human brain contains between 10pow(10) to 10pow(11) neural cells or neurons. These are about 100 different sorts, and half of them are located in the brain's most evolved part, the cerebral cortex. We lose many of the neurons or nerve cells as we go through life. But we grow new neural connections throughout our lives that lead to mature decisions based on life-long experience.

The cerebral cortex has 200 millions of fibers in the corpus coliseum, innumerable associations amongst 10,000 billions of neurons in 4 millions of cortical nodules, and spread over an area of 2500 sq cm with a huge synaptic density. The corpus coliseum inside brain with about 200 million axons connects the right and left hemispheres of the brain.

Each brain cell has the atoms of hydrogen, carbon, oxygen and the other particles.

Brain is a hologram. Information is spread all through the brain. Neuronal activity is widely distributed in brain.

The brain or the spinal cord in return tell the sense organs what they feel and see. Brain is mainly divided into three parts, first cerebrum thinking part, second cerebellum controlling balance and move around, and third medulla top of spinal cord cares breathing, digestion, heart beat. Spinal cord is made up of nerve fiber. Through this the brain sends messages and receives information from the rest of your body. Automatic actions (reflex actions) are controlled by the spinal cord. The brain has around one hundred billion neurons, which can generate and do generate electromagnetic fields for transmission or local interaction between the neurons through various electrical and chemical processes within the brain when inspired by thoughts. In the field of consciousness within and outside the brain. There is constant transmission and communication of energy within  the brain.

The brain is divided, more or less, symmetrically about the front-to-back centerline. The Corpus Callosum, shown in the diagram is a band of thousands of nerve fibres, which connects the two halves of the cortex. Although it is usual to write to the hypothalamus, the amygdala and so on, most of the other parts of the brain are similarly divided, being connected by bundles of fibers called commissures.

The cerebellum is concerned with fine motor behavior, the co-ordination of automatic processes like walking and running. After much practice, learned complex behaviors like riding a bicycle are thought to become controlled by the cerebellum.

At the base of the brain is the brain stem, the medulla, previously mentioned, the pones and an area called the reticular activating system. These form the upper end of the spinal column. There are many nerve junctions (synapses) here and it is where many of the nerves cross over, since in general the left side of the brain controls and senses the right side of the body, and vice versa. The main feature below the cortex is the Limbic System, with a variety of different features. Within the limbic system is the amygdala (not shown in the diagram), the thalamus and the hypothalamus. Just below the last-named is the pituitary gland.

The forebrain has evolved from organs concerned with smell and also taste, the mid-brain with vision, while the hindbrain vibration, sound, and balance. In the diagram the cerebral cortex can be seen almost covers  all the other component parts.  An important reason for relating behavior to the hormone environment is the close coupling of the pituitary gland with the hypothalamus. They are very much the control center for the body, regulating body chemicals, eating, drinking, breathing, body temperature, heart rate and sexual functioning.

In front of the hypothalamus is the optic chiasm, where the nerves from the eyes cross over on their way to the visual cortex at the rear of the brain. There are connections to the suprachiasmatic nucleus in the hypothalamus, to provide information about night and day, working in conjunction with pineal gland, generating circadian rhythms.

In humans the olfactory bulbs have virtually disappeared. They are part of the septum, which connects to the amygdala. Hearing is connected via various nuclei to the auditory cortex.

The hypothalamus is a small organ, but one that affects practically every process in the body.

Amygdala: Towards the rear are two prominences, called the mammilla bodies. In front of these is a bulge, called the median eminence.

The brain can sense the environment, categorize patterns out of multiplicity of signals, select the relevant information from the noise, store it in memory, retrieve this knowledge when required, formulate and execute voluntary response, be it muscular, verbal or emotional. The repeated demonstration of a consistent pattern of local brain activation during such higher mental processes like attention, thought, judgment, pleasure and grief, implies brain's participation is functions other than simply acting as a sensor of the environment. Neuroscience can reveal the physical mechanisms sub serving psychological functions... that awareness is some pattern of activity in neurons.

There is a 'close analogy between quantum processes and our own inner experiences and thought processes'. Most of the modern theories have concentrated on looking for quantum unity (or quantum coherence) somewhere in neural structures. The holographic picture of brain, discovered has established that brain is a hologram- that information is spread all through the brain. Coherence relevant to consciousness is coherence between many different neurons. What brings the unitive or holistic coherence in the whole brain? Vedanta says, such a unity does exist. When anindividual says. 'I' it is in the unity and the unifying force behind the thousand fold-movement of neurons in the brain or the body-mind complex of the individual.

Mind can to some extent be said to be a function of brain, but only if brain is understood not as the detectable macroscopic object, but as the quantum reality underlying both this object and the mental events of consciousness. Mind and brain are manifestations of and viewpoints towards a "single reality", but with important differences. Within the constraints of the hard facts of science, a scientifically describable brain might be able to make use of subtle and largely unknown physical principles in order to perform the needed non-computational actions. Whereas neuron signals may well behave as classically determinate events, the synaptic connections between neurons are controlled at a deeper level, where it is to be expected that there is important physical activity at the quantum-classical borderline. There requires that there be a large-scale quantum-coherent behavior occurring within the microtubules in the cytoskeletons of neurons.

There is an electrostatic field, magnetic field and longitudinal flow of charge carriers in neurons. Electromagnetic field interacts with neuron fields.

Our brain generates and uses electromagnetic waves in the lower microwave frequency region as an integral part of the functioning of the central and peripheral nervous systems.

Experimentally determined electromagnetic properties at mammalian brain tissue indicate the physical necessity for the existence of electromagnetic standing waves called modes in the living mammalian brain. The made characteristics may be determined by two geometric properties at the brain: these are the cephalic index at the brain (its shape in prolate spheroidal coordinates) and the semi-focal distance of the brain (a measure of its size). It was concluded that estimation of brain cephalic index and semi-focal distance using external skull measurements on subjects permits estimation of the subject's characteristic mode frequencies, which in turn will permit a mode-by-mode treatment at the data to simulate hearing

There is the potential energy of an integral protein in the neural membrane. The brain senses the environment, categorizes patterns out of multiplicity of signals, selects  the relevant information from the noise, stores it in memory, retrieves this knowledge when  required, formulates and executes voluntary response, be it muscular, verbal or emotional. The  repeated demonstration of a consistent pattern of local brain activation during such higher  mental processes like attention, thought, judgment, pleasure and grief, implies brain's  participation is functions other than simply acting as a sensor of the environment.

When the light passes through lens and falls on the retina. Immediately a tiny wisp of  electricity is produced. This passes to brain through optic nerve. Similarly rest of the  sensations to hear, smell, taste, skin sense all produce a tiny wisp of electricity, which is  passes to brain through various nerves. The brain receives these signals and understands them.

The brain's electromagnetic field is generated by neuronal electrical activity. The  functioning of the neurons within the brain is itself controlled by the electromagnetic field  generated by thoughts and emotions.

When an individual says 'I' it is in the unity and the unifying force behind the thousand fold-movement of neurons in the brain or the body-mind complex of the individual. In a Similar way our each thought has the unifying force behind the thousand fold-movement of neurons.

An experiment for the first time showed the presence of consciousness in the brain is associated with the presence of 40Hz  (40 oscillations per second) neural oscillatory activity. The same 40Hz continues even in the dream state when our brain is dissociated form external muscular activity, rational thinking and ego. And the same 40 Hz continues even while we use microwave or distant sense other person.
