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.
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.
The brain sends and receives chemical and electrical signals throughout the body. Different signals control different processes, and your brain interprets each. Some make you feel tired, for example, while others make you feel pain. Some messages are kept within the brain, while others are relayed through the spine and across the body’s vast networ...
Each brain hemisphere (parts of the cerebrum) has four sections, called lobes: frontal, parietal, temporal and occipital. Each lobe controls specific functions. 1. Frontal lobe.The largest lobe of the brain, located in the front of the head, the frontal lobe is involved in personality characteristics, decision-making and movement. Recognition of sm...
Pituitary Gland
Sometimes called the “master gland,” the pituitary gland is a pea-sized structure found deep in the brain behind the bridge of the nose. The pituitary gland governs the function of other glands in the body, regulating the flow of hormones from the thyroid, adrenals, ovaries and testicles. It receives chemical signals from the hypothalamus through its stalk and blood supply.
Hypothalamus
The hypothalamus is located above the pituitary gland and sends it chemical messages that control its function. It regulates body temperature, synchronizes sleep patterns, controls hunger and thirst and also plays a role in some aspects of memory and emotion.
Amygdala
Small, almond-shaped structures, an amygdala is located under each half (hemisphere) of the brain. Included in the limbic system, the amygdalae regulate emotion and memory and are associated with the brain’s reward system, stress, and the “fight or flight” response when someone perceives a threat.
Two sets of blood vessels supply blood and oxygen to the brain: the vertebral arteries and the carotid arteries. The external carotid arteries extend up the sides of your neck, and are where you can feel your pulse when you touch the area with your fingertips. The internal carotid arteries branch into the skull and circulate blood to the front part...
Inside the cranium (the dome of the skull), there are 12 nerves, called cranial nerves: 1. Cranial nerve 1: The first is the olfactory nerve, which allows for your sense of smell. 2. Cranial nerve 2: The optic nervegoverns eyesight. 3. Cranial nerve 3: The oculomotor nervecontrols pupil response and other motions of the eye, and branches out from t...
Learn about the main parts of the brain, their functions and how they communicate with each other. The brain is divided into the cerebrum, brainstem and cerebellum, each with different regions and lobes that control various processes.
21. Okt. 2020 · Synonym: Brodmann-Area. Abk.: BA. Definition. Die Brodmann-Areale sind eine Einteilung der Großhirnrinde in Felder, die sich aufgrund ihrer unterschiedlichen Funktionen in Aufbau und Zytoarchitektur ihrer Schichten unterscheiden. Hintergrund.

The brain consists of the cerebrum, the brainstem and the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making decisions as to the instructions sent to the rest of the body.
The Julich Brain Atlas contributes to one of the greatest challenges in science of the 21st century: to understand the human brain and to develop treatments for patients suffering from brain diseases.
