Cerebrum

The cerebrum is the top part of the brain. It receives and gives meaning to information from the sense organs and controls the body. It is also essential for memory, reasoning, communication, emotions, and many other functions. The cerebrum contains two hemispheres split by a central fissure and contains the major lobes of the brain. It does not make up the entire brain, however. The cerebellum and brainstem sit below the cerebrum and work alongside it to control the voluntary actions in the body. Keep reading to learn more about the cerebrum, including its various elements and how they work together. The cerebrum, or telencephalon, is the large upper part of the brain. It is divided into The cerebrum itself has a few divisions, which neuroscientists generally use to classify the functions of the different areas. The sections below will describe these divisions in more detail. Cerebral cortex The cerebral cortex is the outermost layer of the cerebrum, or its gray matter. In humans, this gray matter has an uneven surface with many folds. Ridges called gyri and valleys, or folds, called sulci help increase the surface area of the cerebral cortex. The cerebral cortex also houses the • the frontal lobe • the parietal lobe • the occipital lobe • the temporal lobe These lobes each have two sections, divided by the central fissure in the brain. As there are no other distinct separations in the brain, neuroscientists divide the lobes roughly based on the major folds in the area. M...

The cerebrum is the largest part of your brain and is responsible for many critical everyday functions. This article will give you greater insight into the cerebrum and its vital functions. What Is the Cerebrum? The cerebrum is the single largest part of your brain, divided into two halves called hemispheres. The cerebrum contains different regions that carry out critical functions. Some interesting facts about the cerebrum: • The activity done by one side of your body is typically controlled by the other side of your brain. For example, a stroke on the right side of your brain would affect your left side functions. • The cerebrum makes up roughly 80% of the brain’s volume in an average adult. • To give you an idea of the cerebrum’s size, it’s around three times the size of a baseball and weighs between 2 and 2.5 pounds. • Your brain tissues consist primarily of water, which amounts to 77% of the brain mass. In addition, it also contains lipids (11%) and proteins (8%), while other substances make up the remaining 4%. • Although different parts of your brain carry out different functions, the notion of a “left-brained” or “right-brained” individual is considered something of a myth without any scientific proof. Cerebrum Location The cerebrum is located in your skull. It’s positioned at the top and front side of your brain. Cerebrum Anatomy The external layer of your cerebrum is called the cerebral cortex, mostly made up of smooth, folded tissue that looks similar to a walnu...

Synonyms: Forebrain, Endbrain , The brain, along with the spinal cord, is the main organ of the central nervous system. It is the most complex organ of the body, with many layers and components that play their roles in almost every function performed by the body. The brain is composed of the cerebrum is the largest part of the brain, and is divided into a left and right hemisphere. Although the cerebrum appears to be a uniform structure, it can actually be broken down into separate regions based on their Each hemisphere of the cerebrum is composed of the The cerebral cortex is divided into six lobes: the This article will discuss the Key facts about the lobes of the brain Frontal lobe Location: Corresponds to the frontal bone; Anterior to the parietal lobe (separated by central sulcus) and superior and anterior to the temporal lobe (separated by lateral sulcus - Sylvian fissure) Gyri: Superior, middle and inferior frontal gyri, precentral gyrus Function: Control of voluntary movement, involved in attention, short term memory tasks, motivation, planning, speech Parietal lobe Location: Corresponds to the parietal bone; Superior to the occipital lobe (separated by parietooccipital sulcus) and posterior to the frontal lobe (separated by central sulcus) Gyri: Postcentral gyrus, superior and inferior parietal lobules Function: Integrates proprioceptive and mechanoceptive stimuli, involved in language processing Temporal lobe Location: Corresponds to the temporal bone; Inferior ...

• Gray matter, which is named for its gray-brown color, forms the outer surface of the brain and consists of the neurons' cell bodies. This outer layer of gray matter is the cerebral cortex and it is associated with most information processing, including language, perception, and thought. • White matter is an inner core of brain tissue that's mostly composed of axons, or nerve fibers, that are covered by myelin (a type of fat). The myelin gives white matter its white color. The wrinkly outer layer of the cerebrum is called the cerebral cortex and it's all gray matter. The gray matter consists of the central part of nerve cells. The rest of the cerebrum is mostly white matter, which has branches of nerve fibers for sending messages between nerve cells. Lobes The gray matter of the cerebral cortex is divided lengthwise into two halves, separated by a deep crease called the longitudinal fissure. • Frontal lobes reside at the very front of the brain behind the forehead and are responsible for many key functions, such as attention, learning, and speech. The prefrontal cortex (PFC), a forward-facing region of each frontal lobe, allows for planning and complex decision making and is said to house your personality. A rear-facing region is involved in voluntary movements. • Parietal lobes are located near the middle of the brain behind the frontal lobes and are sensory areas that process pain, taste, temperature, and textures along with spatial relationships (such as the distance b...

Table of Contents • • • • • • • • • • • The cerebrum makes up a large portion of the brain. It is what people refer to when they describe someone as left- or right-brained. The cerebrum is home to many smaller structures that regulate numerous core functions in the entirety of the human body. Functions controlled by minor structures of the cerebrum are the interpretation of sensory information, emotions, learning, problem-solving, motor control, and much more. The outer layer of the cerebrum, the cerebral cortex, is referred to as “the hub of thought” and is integral to cognitive function. Two hemispheres make up the whole of the cerebrum, the left, and right hemisphere. They control the symmetrical divisions of the body opposite to them: the left hemisphere controls the muscles on the right side of the body, and the right hemisphere controls the left muscles. The two regions are connected by the corpus callosum and together compose what is considered to be a part of key characteristics setting humans apart from non-human animals. The Left and Right Hemispheres Although the left and right hemispheres do not function independently of one another, there are certain functions for which one hemisphere excels over the other. A Left Hemisphere Right Hemisphere Analytical skills/Problem solving Creativity Logic Imagination Reasoning Spatiotemporal awareness Language Reflective, conscious thought Calculations; Mathematics Music interpretation Visual imagery Muscles of the right si...
