According to him, the third part, the neocortex, controls speech and reasoning and is the most recent evolutionary arrival. [41] The concept of the limbic system has since been further expanded and developed by Walle Nauta , Lennart Heimer , and others.
A heuristic model of the neural pathway of the Papez circuit shows the connections between its different parts. Based on Papez's experiment with aggression in rats and other studies, it was initially believed that the circuit was involved with emotion. The circuit connects the hypothalamus and the cortex and acts as the emotional system of the ...
A 3D medical animation still shot showing different parts of the midbrain. The brainstem (or brain stem) is the posterior stalk-like part of the brain that connects the cerebrum with the spinal cord. [1] In the human brain the brainstem is composed of the midbrain, the pons, and the medulla oblongata. [1]
The hippocampus (pl.: hippocampi; via Latin from Greek ἱππόκαμπος, 'seahorse') is a major component of the brain of humans and other vertebrates.The hippocampus is part of the limbic system, and plays important roles in the consolidation of information from short-term memory to long-term memory, and in spatial memory that enables navigation.
Blood to the medulla is supplied by a number of arteries. [3] Anterior spinal artery: This supplies the whole medial part of the medulla oblongata. Posterior inferior cerebellar artery: This is a major branch of the vertebral artery, and supplies the posterolateral part of the medulla, where the main sensory tracts run and synapse. It also ...
Most famous parts of the brain highlighted in different colours The human brain anatomical regions are ordered following standard neuroanatomy hierarchies. Functional , connective , and developmental regions are listed in parentheses where appropriate.
The outer part of the cerebrum is the cerebral cortex, made up of grey matter arranged in layers. It is 2 to 4 millimetres (0.079 to 0.157 in) thick, and deeply folded to give a convoluted appearance. [21] Beneath the cortex is the cerebral white matter. The largest part of the cerebral cortex is the neocortex, which has
The cortical and medial nuclei connect with the olfactory system and hypothalamus. [4] The central nucleus has extentive projections to the brainstem. [4] Anatomically, the amygdala [12] and more particularly, its central and medial nuclei [13] have sometimes been classified as a part of the basal ganglia.
