What is the brain model of the athlete's way?
While writing the manuscript for The Athlete’s Way: Sweat and the Biology of Bliss, I spoke with my father every day. Together, we created the “Bergland Split-Brain Model” which we referred to as ‘up brain-down brain.’ The ‘up’ brain included both hemispheres of the cerebrum, and the 'down' brain included both hemispheres of the cerebellum. This was a direct and cogent attempt to shift the focus from east-west across the corpus callosum to north-south across the midbrain. I realize now, that as part of my system of belief and creating a new paradigm, the 'up brain-down brain' framework was an important stepping stone, but not completely accurate.

What is the surface of the cerebrum?
The surface of the cerebrum is known as the cortex. It is about two-millimeter-thick and has many folds forming ridges (gyri) and grooves (sulci). A fissure is a deeper grove and is often used interchangeably with sulcus. The cerebrum is divided into a left and right hemisphere by a longitudinal fissure that goes by many different names: longitudinal fissure, cerebral fissure, median longitudinal fissure, interhemispheric fissure. Each cerebral hemisphere divides into four separate lobes by a central sulcus, parieto-occipital sulcus, and lateral fissure. The central sulcus runs posterior-medial to anterior-lateral and separates the frontal lobe from the parietal lobe. The parieto-occipital sulcus separates the parietal lobe from the occipital lobe. The lateral fissure (Sylvian fissure) is a laterally located horizontal fissure and separates the temporal lobe from the frontal and parietal lobe.
Which lobe of the brain controls touch?
The parietal lobe is posterior to the central sulcus and anterior to the parieto-occipital sulcus. This lobe controls perception and sensation. The primary somatosensory cortex is in the postcentral gyrus and is positioned immediately posterior to the central sulcus. The primary somatosensory cortex controls the sense of touch, temperature, and pain of the contralateral body. Mirroring the primary motor cortex, the medial region senses the lower extremity, superior-lateral region sense the upper extremity and hand, and the lateral region senses the face. Similar to the primary motor area, the hands, face, and lips take up the majority of the somatosensory area and are also well presented by the homunculus model. Damage to the parietal lobe can present with a lack of these sensations as well as other symptoms depending on whether the dominant or nondominant hemisphere is farther damage. Damage to the dominant parietal lobe, usually the left hemisphere, present with agraphia, acalculia, finger agnosia, and left-right disorientation. The presentation of these symptoms is characteristic of Gerstmann Syndrome.[2] Damage to the nondominant parietal lobe, usually the right hemisphere, present with agnosia of the contralateral side of the world - this is also called hemispatial neglect syndrome.
Which lobe of the brain controls judgment, problem solving, planning, behavior, personality, speech, writing, speaking?
The primary motor cortex is present in the precentral gyrus of the frontal lobe and is positioned immediately anterior to the central sulcus.
Which lobe of the brain controls the executive and motor functions?
Frontal Lobe. The frontal lobe is anterior to the central sulcus and superior to the lateral fissure. The frontal lobe further divides into a superior, middle, and inferior frontal gyrus, primary motor cortex, and orbital area. These areas combine to controls our executive and motor functions.
What are the nerves that travel to and from the brain?
Nerves that travel to and from the brain consist of dendrites, a cell body, axon, and axon terminal. Grey matter is commonly used interchangeably with the cortex. However, the grey matter implies that axons that are not myelinated appear grey. Grey matter can be found in deep structures, as well.
Which lobe of the brain is responsible for memory?
Limbic system: The temporal lobe is an important component of the limbic system, which is responsible for learning, emotions (love, envy, etc.) and memory. It helps form conscious long-term memory. Due to the presence of the limbic system, the temporal lobe contributes to a variety of autonomic states and physiological processes, such as sexual arousal, anxiety levels, and hunger.
What is the cerebrum?
The cerebrum contains grey matter and billions of unmyelinated neurons (brain cells) called the cerebral cortex. Deeper parts of the cerebrum contain white matter, which is the collection of myelinated nerve fibers that connect different regions of the central nervous system (CNS) and spinal cord. Myelin sheath insulates and covers the neurons intermittently, helping to speed up nerve signals.
What are the folds of the cerebral cortex?
The cerebral cortex that is present superficially to the cerebrum is arranged in a folded manner and is only 2-4 millimeters thick. The folds on the cerebral cortex are called gyri, which are divided by grooves. The smaller grooves are called sulci and larger groves are called fissures. The fold of the sulci conceals about 66% of the brain's surface, with a total surface area of approximately 16 square feet. The cerebral cortex folds are the reason for the distinctive look of the brain.
How many lobes does the cerebrum have?
The cerebrum is divided into four major lobes, each lobe with two halves, right and left. All four right halves come into the right hemisphere of the cerebrum and all four left halves come into the left hemisphere.
Where is the occipital lobe?
Occipital lobe: Occipital lobe is in the backside of the upper brain below the occipital bone of the skull, behind the parietal and temporal lobes, and above the cerebellum. The central cerebral fissure divides the two occipital lobes, and a membrane called tentorium cerebelli separates it from the cerebellum. The occipital lobe is identified by the folds sulci and gyri. The occipital lobe is divided into four parts, each of which is responsible for a separate set of visual functions. Damage to the occipital lobe may lead to problems with vision.
Where is the parietal lobe located?
Parietal lobe: Parietal lobe is located behind the frontal lobe and above the temporal lobe, toward the upper area of the skull. The two parietal lobes are separated by the central sulcus. Temporal and parietal lobes are separated by the lateral sulcus, also called Sylvian fissure. The parietal lobe is a primary sensory area that interprets higher functions. It can perceive sensory information from outside the body, such as touch, pressure, pain, taste, and temperature. It helps the brain understand symbols, written and spoken linguistic issues, mathematical problems, codes, and riddles.

Anatomy of The Cerebrum
Function
- The role of the cerebrum is to coordinate and process sensory and motor functions required by the body, as well as to provide reasoning functions, process emotions, and contribute the unique personality traits that make each human being an individual. The cerebrum performs these functions using communication between nerve cells. Some of these proce...
Associated Conditions
- Traumatic injury and an array of medical conditions can affect the cerebrum. Each can lead to many different types of problems with brain function depending on which regions of the cerebrum are affected or have the most damage. Conditions that affect the cerebrum may include: 1. Brain trauma occurs if a high-force accident shakes the brain inside the skull or if a projectile penetrat…
Tests
- Some brain conditionsare not diagnosed primarily through medical testing. For example, diagnosing Alzheimer's disease may rely on a person's individual and family medical histories and cognitive function testing. Other cerebral conditions may be diagnosed through different types of medical testing—alone, or in combination. Common types include: 1. Lumbar puncture (spinal ta…
Summary
- The cerebrum is a major part of the brain and its upper layer called the cerebral cortex is responsible for a range of complex functions. The cerebrum is the source of intellect and personality. It helps you move and understand what you see, hear, touch, and smell. Due to the cerebrum's many important roles, damage to any of its lobes from injuries, illnesses, or chronic c…
