What is the midbrain? The midbrain (mesencephalon) is a part of the brainstem in the brain. Among other things, it is responsible for the control of coordination. In addition, it plays an important role for hearing and seeing, but also for the sensation of pain. The midbrain consists of different parts: Towards the back (dorsal) … Midbrain (Mesencephalon): Anatomy & Function
What is the blood-brain barrier? The blood-brain barrier is a barrier between the blood and the brain substance. It is formed by the endothelial cells on the inner wall of the blood capillaries in the brain and the astrocytes (a form of glial cells) surrounding the vessels. The endothelial cells in the capillary brain vessels … Blood-Brain Barrier: Structure and Function
What is the brain stem? The brain stem is the developmentally oldest part of the brain. Together with the diencephalon, sometimes also with the cerebellum and parts of the terminal brain, it is often referred to synonymously as the brain stem. However, this is not correct: the brain stem includes all parts of the brain … Brainstem: Function, Structure, Damage
What is the medulla oblongata? The medulla oblongata (myelencephalon, afterbrain) is the lowest and rearmost area of the brain. After transition from the spinal cord, it thickens in an onion shape and ends at the bridge. The myelencephalon contains cranial nerve nuclei and is thus the origin of cranial nerves VII to XII, which emerge … Medulla Oblongata: Structure and Function
What is the hippocampus? The hippocampus is a brain region that belongs to the limbic cortex (limbic system). The name means “seahorse” because this brain region has a similar shape to the small sea creature. It belongs to the allocortex, which is a developmentally very old part of the cerebral cortex. The hippocampus is part … Hippocampus: Function & Anatomy
Where is the thalamus located in the brain? The thalamus is located deep in the center of the brain, in the so-called diencephalon. It consists of two halves, the left and the right thalamus. One part is therefore located in the left hemisphere, the other in the right hemisphere. The halves of the thalamus are … Thalamus: Function, Anatomy, Disorders
What is the cerebrospinal fluid? The cerebrospinal fluid (CSF) is a clear, colorless fluid that is low in protein and cells. An adult has about 130 to 150 milliliters of cerebrospinal fluid. About one-fourth of it is in the cerebral ventricles (ventricles), and three-fourths surrounds the brain and spinal cord as an enveloping mantle of … Cerebrospinal fluid: Composition & function
What is the brain? The brain (encephalon) is the part of the central nervous system that lies within and fills the bony skull. It consists of countless nerve cells that are connected to and control the organism via afferent and efferent nerve pathways. The brain volume (human) is about 20 to 22 grams per kilogram … Brain: Structure and Function
What is the amygdala? The amygdala (corpus amygdaloideum) is a sub-region within the limbic system, consisting of two bean-sized clusters of nerve cells. Through the connection with other brain regions, the meaning of various signals is evaluated here and these are then projected from the amygdala (together with the hippocampus) to the cerebral cortex via … Amygdala: Function and Structure
What is the hypothalamus? The hypothalamus is an area of the diencephalon. It consists of nerve cell clusters (nuclei) that act as switching stations for the pathways leading to and from other parts of the brain: Thus, the hypothalamus receives information from the hippocampus, amygdala, thalamus, striatum (group of basal ganglia), the cortex of the … Hypothalamus: Function, Anatomy, Disorders
