Name the most important part of the human brain

Your cerebral cortex, also called gray matter, is your brain’s outermost layer of nerve cell tissue. It has a wrinkled appearance from its many folds and grooves. Your cerebral cortex plays a key role in memory, thinking, learning, reasoning, problem-solving, emotions, consciousness and functions related to your senses. Anatomy of the cerebral cortex. What is the cerebral cortex? Your cerebral cortex is the outermost layer of your Your cerebral cortex consists of six layers of nerve cells that contain between 14 billion and 16 billion nerve cells. It’s two millimeters (mm) to four mm (0.08 inches to 0.16 inches) thick. Your cortex is divided into four lobes: frontal, parietal, temporal and occipital. Each of these lobes is responsible for processing different types of information. Collectively, your cerebral cortex is responsible for the higher-level processes of the human brain, including language, memory, reasoning, thought, learning, decision-making, emotion, intelligence and personality. Why is the cerebral cortex called gray matter? The gray matter found in the outer layer of your brain consists of nerve cell bodies, including the end portion of nerves called dendrites. Dendrites are the part of a nerve cell that receives the chemical message from another cell. Your cerebral cortex is gray because that section of the nerve lacks the fatty covering material called myelin. White matter in your brain is made up of bundles of axons, the long center section of a nerve cell...

New Delhi: The human brain's cerebellum is more vulnerable to Covid infections than other brain regions, a new study employing an innovated MRI technique has found. The study from Rotman Research Institute and Sunnybrook Hospital in Toronto, Canada, reinforces the idea that Covid can lead to changes in the brain, it said. The new imaging technique, called correlated diffusion imaging (CDI), was developed by Alexander Wong, a systems design engineering professor, University of Waterloo, Canada. A new form of MRI, CDI can better highlight the differences in the way water molecules move in tissue by capturing and mixing MRI signals at different gradient pulse strengths and timings, the study published in the journal Human Brain Mapping said. Wong had previously developed CDI as a better imaging measure for detecting cancer. The CDI imaging of frontal-lobe white matter (in the brain's cerebrum) revealed a less restricted diffusion of water molecules in COVID-19 patients. At the same time, it showed a more restricted diffusion of water molecules in the cerebellum of patients with COVID-19. "Some may think COVID-19 affects just the lungs," Wong said. "What was found is that this new MRI technique that we created is very good at identifying changes to the brain due to COVID-19. COVID-19 changes the white matter in the brain." In addition to being one of the few studies showing COVID-19's effects on the brain, the study said that it is the first to report diffusion abnormalities i...

What is the brain? The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body. Together, the brain and spinal cord that extends from it make up the central nervous system, or CNS. What is the brain made of? Weighing about 3 pounds in the average adult, the brain is about 60% fat. The remaining 40% is a combination of water, protein, carbohydrates and salts. The brain itself is a not a muscle. It contains blood vessels and nerves, including neurons and glial cells. What is the gray matter and white matter? Gray and white matter are two different regions of the central nervous system. In the brain, gray matter refers to the darker, outer portion, while white matter describes the lighter, inner section underneath. In the spinal cord, this order is reversed: The white matter is on the outside, and the gray matter sits within. Gray matter is primarily composed of neuron somas (the round central cell bodies), and white matter is mostly made of axons (the long stems that connects neurons together) wrapped in myelin (a protective coating). The different composition of neuron parts is why the two appear as separate shades on certain scans. Each region serves a different role. Gray matter is primarily responsible for processing and interpreting information, while white matter transmits that information to other parts of the nervous system. How does the brain work? The brai...

Encased in the skull, the brain is the body’s centralized conveyor of all information. Much of its job involves receiving information from the rest of the body, interpreting that information, and then guiding the body’s response to it. Input the brain interprets includes odor, light, sound, and pain, and these are gathered from organs located in the head. Major sensory organs located in the head include: • Ears: The outer, middle, and inner ear are responsible for collecting auditory information. Sound waves travel through the ears and vibrate membranes and tiny bones. Those signals are sent to the brain via the vestibulocochlear nerve. Other than hearing, your inner ears also help you keep your balance. • Eyes: Light rays pass through the eye and refract through the vitreous humor, or liquid part of the eye. This stimulates the optic nerve, which sends the information to the brain. • Tongue: Thanks to taste buds, the food you eat is vibrant with flavor. Whether food is sweet, salty, sour, or bitter, a normal tongue can taste it all. The taste buds collected the tastes, and three nerves (facial, glossopharyngeal, and vagus) send the information to the brain where it is interpreted. The tongue also helps you speak; its movement inside the mouth helps form sounds that become words. • Nose: Olfactory nerves in your upper nasal cavity send messages to your brain to help you distinguish an infinite number of smells. The sense of smell also aids your sense taste. • Nerves: Nerve...

Your brain’s frontal lobe is home to areas that manage thinking, emotions, personality, judgment, self-control, muscle control and movements, memory storage and more. Just as its name indicates, it’s the forward-most area of your brain. Your frontal lobe is a key area of study for both brain-related and mental health-related fields of medicine. Overview The frontal lobe is the front-most part of your brain. It’s responsible for control over many abilities, including the way you think, how you move and how you remember things. It’s also a key part in your social skills, and helps you understand and control how you talk, behave and interact with others. What is the frontal lobe? The frontal lobe is one of five lobes of your Function What does the frontal lobe do? Your frontal lobe handles many abilities, including: • Reasoning: This includes simple and complex processing of information. Logic, reasoning, judgment, decision-making and creativity all fall into this category. • Social understanding: Your frontal lobe controls your understanding of social norms and helps determine what you should and shouldn’t do or say. • Executive functions: Some examples of these include self-control and inhibitions, attention span and working memory. • Voluntary muscle movements: These are intentional movements, such as moving your hand to pick something up or moving your legs to stand up and walk around. Your frontal lobe also contains the brain area that controls the muscles you use for sp...

Share on Pinterest Brain size can vary, depending on age, sex, and overall body mass. In a poem written around 1892, American poet Her verses express a sense of awe, considering the brain’s marvellous capacities of thought and creativity. Musing on how this fascinating organ is able to encompass so much information about the self and the world, she wrote: “The Brain — is wider than the Sky — For — put them side by side — The one the other will contain With ease — and You — beside” The main organ of the human nervous system, the brain manages most of our bodies’ activities and processes information received from both outside and inside the body and is the very seat of our emotions and cognitive abilities, including thought, long- and short-term memory, and decision-making. The first mention of this organ was recorded in an Ancient Egyptian medical treatise known as the “ Since then, our understanding of the brain has expanded immeasurably, although still we contend with many mysteries surrounding this key organ. In this Spotlight, we look at some of the most important facts we have uncovered about the brain — and some aspects that remain to be understood. Brain size varies widely, depending largely on age, sex, and overall body mass. However, studies have suggested that the adult male brain weighs, on average, about In terms of dimensions, the human brain isn’t the largest. Of all mammals, the sperm whale — an underwater denizen weighing an impressive 35–45 tons — is known ...

Cerebrum is the main part of the brain, which helps in thinking, and processing information, and memory, and what-not. It's the center of human intelligence. Hypothalamus has many vital, like so-important-you-can't-live-without-it functions like: • releasing hormones for the pituitary gland to produce growth hormones, • regulating body temperature, • controlling emotions like hunger, thirst, lust etc. Pituitary gland is the master gland of our body. And as the name suggests, it: • regulates the work of all other endocrine glands, and • releases the Growth-Stimulating Hormone (GSH), which results in the height and basically, the overall growth of the body. Hope this helps and if I'm mistaken, I apologize and please let me know. :) Diencephalon consists of pineal gland, thalamus and hypothalamus. Pineal gland is located near the centre of the brain. It releases melatonin which affects the wake and sleep patterns. It also affects reproduction development. Thalamus gland is located above the brain stem which relays sensory and motor signals to the brain (specifically, the cerebral cortex). Hypothalamus is located at the base of the brain near the pituitary gland. It plays an important role in the release of many hormones.For example, when the level of growth hormone is low, the hypothalamus releases growth-hormone-releasing-factor which stimulates the pituitary gland to release the growth hormone. It also regulates body temperature. hope this explanation helped you and if ther...
