The principal subdivision of the thalamus into nucleus groups is the trisection of each thalamus (left and right) by a Y-shaped internal medullary lamina. This trisection divides each thalamus into anterior, medial and lateral groups of nuclei. [8] The medial group is subdivided into the medial dorsal nucleus and midline group.
In neuroanatomy, the lateral geniculate nucleus (LGN; also called the lateral geniculate body or lateral geniculate complex) is a structure in the thalamus and a key component of the mammalian visual pathway. It is a small, ovoid, ventral projection of the thalamus where the thalamus connects with the optic nerve. There are two LGNs, one on the ...
Olivary body. Inferior olivary nucleus; Rostral ventrolateral medulla; Caudal ventrolateral medulla; Solitary nucleus (Nucleus of the solitary tract) Respiratory center-Respiratory groups. Dorsal respiratory group; Ventral respiratory group or Apneustic centre. Pre-Bötzinger complex; Botzinger complex; Retrotrapezoid nucleus; Nucleus ...
The limbic system, also known as the paleomammalian cortex, is a set of brain structures located on both sides of the thalamus, immediately beneath the medial temporal lobe of the cerebrum primarily in the forebrain. [1] Its various components support a variety of functions including emotion, behavior, long-term memory, and olfaction. [2]
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.
The interthalamic adhesion (also known as the massa intermedia, intermediate mass or middle commissure) is a flattened band of tissue that connects both parts of the thalamus at their medial surfaces. The medial surfaces form the upper part of the lateral wall to the third ventricle.
Thalamic nuclei: (left thalamus, left view) MNG = Midline nuclear group AN = Anterior nuclear group MD = Medial dorsal nucleus VNG = Ventral nuclear group VA = Ventral anterior nucleus VL = Ventral lateral nucleus VPL = Ventral posterolateral nucleus VPM = Ventral posteromedial nucleus LNG = Lateral nuclear group PUL = Pulvinar MTh = Metathalamus
Although the human brain represents only 2% of the body weight, it receives 15% of the cardiac output, 20% of total body oxygen consumption, and 25% of total body glucose utilization. [138] The brain mostly uses glucose for energy, and deprivation of glucose, as can happen in hypoglycemia , can result in loss of consciousness. [ 139 ]
