The key questions here are to identify which parts of the brain are involved in sleep onset and what their mechanisms of action are. [92] In humans and most animals sleep and wakefulness seems to follow an electronic flip-flop model i.e. both states are stable, but the intermediate states are not.
The epithalamus also serves as a connecting point for the dorsal diencephalic conduction system, which is responsible for carrying information from the limbic forebrain to limbic midbrain structures. [ 4 ] [ 5 ] Some functions of its components include the secretion of melatonin from the pineal gland ( circadian rhythms ), regulation of motor ...
Embryonic vertebrate subdivisions of the developing human brain hindbrain or rhombencephalon is a developmental categorization of portions of the central nervous system in vertebrates. It includes the medulla , pons , and cerebellum .
Paul D. MacLean, as part of his triune brain theory (which is now considered outdated [citation needed] [30] [31]), hypothesized that the limbic system is older than other parts of the forebrain, and that it developed to manage circuitry attributed to the fight or flight first identified by Hans Selye [32] in his report of the General ...
The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system. The brain integrates the instructions sent to the rest of the body. The cerebrum, the largest part of the human brain, consists of two cerebral hemispheres.
Human brain in the coronal orientation. Amygdalae are shown in dark red. The amygdala (/ ə ˈ m ɪ ɡ d ə l ə /; pl.: amygdalae / ə ˈ m ɪ ɡ d ə l i,-l aɪ / or amygdalas; also corpus amygdaloideum; Latin from Greek, ἀμυγδαλή, amygdalē, 'almond', 'tonsil' [1]) is a paired nuclear complex present in the cerebral hemispheres of vertebrates.
The olfactory system is the pathway between the nose and the brain. The system detects smell by processing the tiny odor molecules that waft off of various objects, such as baking bread or a ...
The hippocampus is a structure in the brain that has been associated with various memory functions. It is part of the limbic system, and lies next to the medial temporal lobe. It is made up of two structures, the Ammon's Horn, and the Dentate gyrus, each containing different types of cells. [1]
