The brainstem (or brain stem) is the stalk-like part of the brain that connects the forebrain (the cerebrum and diencephalon) with the spinal cord. [ 1] In the human brain, the brainstem is composed of the midbrain, the pons, and the medulla oblongata. [ 1][ 2] The midbrain is continuous with the thalamus of the diencephalon through the ...
Cortical areas: Limbic lobe. Orbitofrontal cortex: a region in the frontal lobe involved in the process of decision-making. Piriform cortex: part of the olfactory system. Entorhinal cortex: related to memory and associative components. Hippocampus and associated structures: play a central role in the consolidation of new memories.
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.
Medulla oblongata. The medulla oblongata or simply medulla is a long stem-like structure which makes up the lower part of the brainstem. [ 1] It is anterior and partially inferior to the cerebellum. It is a cone-shaped neuronal mass responsible for autonomic (involuntary) functions, ranging from vomiting to sneezing. [ 2]
The cerebrum is the largest part of the brain. Depending upon the position of the animal, it lies either in front or on top of the brainstem. In humans, the cerebrum is the largest and best-developed of the five major divisions of the brain. The cerebrum is made up of the two cerebral hemispheres and their cerebral cortices (the outer layers of ...
Scheme of the roof of the fourth ventricle. The hindbrain, rhombencephalon (shaped like a rhombus) or lower brain [1] is a developmental categorization of portions of the central nervous system in vertebrates. It includes the medulla, pons, and cerebellum. Together they support vital bodily processes.
The cerebral cortex, also known as the cerebral mantle, [ 1] is the outer layer of neural tissue of the cerebrum of the brain in humans and other mammals. It is the largest site of neural integration in the central nervous system, [ 2] and plays a key role in attention, perception, awareness, thought, memory, language, and consciousness.
Neuronal precursor cells proliferate in the ventricular zone of the developing neocortex, where the principal neural stem cell is the radial glial cell. The first postmitotic cells must leave the stem cell niche and migrate outward to form the preplate, which is destined to become Cajal–Retzius cells and subplate neurons. These cells do so by ...
