How To Use Your Right Brain More – The vertebrate brain (cerebrum) consists of two cerebral hemispheres separated by a canal and a longitudinal fissure. Therefore, the brain can be described as divided into left and right cerebral hemispheres. Each of these hemispheres has an outer layer of gray matter, the cerebral cortex, supported by an inner layer of white matter. In eutherian (milk-bearing) mammals, the hemispheres are connected by the corpus callosum, a group of very large nerve fibers. Smaller commissures, including the anterior, posterior, and fornix, also connect to the hemispheres, and these are also present in other vertebrates. These commissures transmit information between the two hemispheres to coordinate local functions.
Three poles of the cerebral hemispheres are known: the occipital, frontal, and temporal poles.

The sulcus is a prominent fissure that separates the parietal from the frontal lobes and the primary motor cortex from the primary somatosensory cortex.

Macroscopically, the two hemispheres are more or less mirror images of each other, with only subtle differences, such as the Yakovlev moment in the human brain, which is a slight right-hand bend that makes it go from left to right. At the microscopic level, the cellularity of the cerebral cortex reveals abundance of cellular function, neurotransmitter levels, and receptor subtypes that are markedly asymmetric between hemispheres.
However, while some of these hemispheric distribution differences are caused by humans or certain species, many observable distribution differences vary from species to species within a given species.
Each cerebral hemisphere has the outer layer of the cerebral cortex, known as gray matter, and the inner layer of white matter, or core, called the semiovale, inside the hemisphere.
The interior of the cerebral hemispheres includes the lateral ventricles, basal ganglia, and white matter.

The brain has three poles, the occipital, frontal and temporal poles. The occipital pole is the posterior d of each occipital lobe in each hemisphere. It is more pointed than the round front pillar. The frontal pole is located at the most anterior portion of the frontal lobes of each hemisphere and is more rounded than the occipital pole. The temporal pole is located between the frontal and occipital poles, anterior to the middle cranial fossa of each temporal lobe.
If the upper portion of either hemisphere is removed, at a level approximately 1.25 cm above the corpus callosum, the central white matter is exposed as an oval area, the semioval, surrounded by a narrow border around the gray matter. And filled with many small red spots (vascular spots), which are caused by blood leaking from broken blood vessels.
If the rest of the hemispheres are separated slightly, a broad band of white matter, the corpus callosum, will be seen joining them at the base of the interhemispheric fissure; the edge of the hemisphere that coincides with the corpus callosum is called the labia cerebrum.
Each labia is part of the cingulate gyrus already described; the duct between it and the upper surface of the corpus callosum is called the groove of the corpus callosum.

If the hemisphere is flush with the upper surface of the corpus callosum, the white matter of this structure connects the two hemispheres.
Much of the now exposed medulla is surrounded by a convoluted border of gray matter, called the semiovale. The blood supply to the semiovale comes from the superficial middle cerebral artery.
The cerebral hemispheres originate from the telencephalon. They appear five weeks after conception and appear as bilateral intussusceptions. The hemisphere grows in a C shape and grows backward, pulling on any structures within the hemisphere (such as the ventricular canal). The intraventricular foramen (also known as the foramen of Monro) allow communication with the lateral ventricles. The choroid plexus is composed of epithelial cells and vascular stroma.
In pop psychology, there are often broad generalizations about certain functions (e.g., logic, creativity) that are lateralized, i.e. located on the right or left side of the brain. These statements are often inaccurate because most brain functions are actually distributed between the two hemispheres. Most of the scientific evidence for asymmetry has to do with low-level perceptual functions rather than the commonly discussed higher-level functions (e.g., subconscious processing of grammar, rather than “logical thinking” in general).

In addition to this lateralization of certain functions, low-level inhibition should also inhibit the contralateral side of the body.
The best example of established lateralization is Broca’s area and Wernicke’s area (language), which are usually only found in the left hemisphere. However, these regions usually correspond to the dominant hand, which means that the localization of these regions is usually in the opposite hemisphere to the dominant hand. Lateralization of functions such as semantics, intonation, activation and prosody has been challenged and largely found to have a neuronal basis in both hemispheres.
Perceptual information is processed in both hemispheres, but distributed laterally: information from each side of the body is sent to the opposite hemisphere (visual information is distributed slightly differently, but still laterally). Likewise, the motor control signals sent to the body also come from the opposite hemisphere. Hand preference (which hand someone prefers to use) has also been linked to hemispheric lateralization.
In some respects, the hemispheres are asymmetrical; the right side is slightly larger. On the right are higher levels of the neurotransmitter norepinephrine and on the left are higher levels of dopamine. There is more white matter (longer axons) on the right and more gray matter (cell bodies) on the left.

Linear reasoning functions of language, such as grammar and word formation, are generally biased towards the left hemisphere of the brain. In contrast, overall verbal reasoning functions such as intonation and stress are generally biased towards the right hemisphere of the brain. Other integrated functions, such as intuitive or heuristic algorithms, binaural sound localization, etc., appear to be more bilaterally driven.
In the treatment of epilepsy, the corpus callosum may be severed to sever the main connection between the brain hemispheres, a procedure known as a corpus callosotomy.
A hemispherectomy is the removal or disabling of one of the brain’s hemispheres. This is a rare procedure used in certain cases of extreme seizures that do not respond to other treatments. Scientists and experts have long studied the human brain and discovered cognitive differences between the left and right hemispheres. Each page serves a different purpose and has different options and functions.
Even though we use each equally, sometimes one seems more powerful than the other. However, this theory of “mind domination” has been proven wrong. People can’t be “left-brained” or “right-brained” — each hemisphere is equally important. The right brain is responsible for imagination, visualization, and creativity, as well as artistic expression such as singing, painting, and dancing. The left brain is responsible for language, writing, reading and calculations – it helps us analyze and reason.

If one side of your brain seems stronger than the other, it’s only developed through practice. There are a few things you can do to train each hemisphere. You can exercise your left brain by doing puzzles, writing, practicing math, coding and programming. For an extra boost to your right side, try dancing, singing, drawing, meditating, or exercising.

The Brain Is A Very Complex Organ And It Plays A Crucial Role Not Only In Thinking But All Bodily Functions. It Divided into two halves, the right brain and the left brain. Specific areas are responsible for different functions, but the brain functions as a whole.
The human brain is a complex organ. It weighs about 3 pounds and contains about 100 billion neurons and 100 trillion connections. The mind is the control center of everything you think, feel and do.

Both sides of the brain are very similar, but the way they process information is very different. Despite their distinct styles, the two halves of the brain don’t work independently of each other.
Nerve fibers connect different parts of the brain. If a brain injury disrupts the connection between the two sides, you can still function normally. But the lack of integration does some damage.
The human mind is constantly reorganizing itself. It can adapt to change, both physically and through life experiences. It is specially made for learning.
As scientists continue to map the brain, we are gaining a better understanding of which parts control basic functions. This information is critical to advancing research and rehabilitation from brain diseases and injuries.
