Korsakoff syndrome stems from damage to the mammillary body, the mammillothalamic fasciculus or the thalamus. [ 68 ] [ 69 ] Fatal familial insomnia is a hereditary prion disease in which degeneration of the thalamus occurs, causing the patient to gradually lose their ability to sleep and progressing to a state of total insomnia , which ...
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 ...

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 caudate nuclei are near the center of the brain, sitting astride the thalamus. There is a caudate nucleus in each hemisphere of the brain. Each nucleus is C-shaped, with a wider "head" (caput in Latin) at the front, tapering to a "body" (corpus) and a "tail" (cauda). Sometimes a part of the caudate nucleus is called the "knee" (genu).

A major output goes via the fornix to the lateral septal area and to the mammillary body of the hypothalamus (which the fornix interconnects with the hippocampus). [21] The hippocampus receives modulatory input from the serotonin, norepinephrine, and dopamine systems, and from the nucleus reuniens of the thalamus to field CA1.
The ventral posteromedial nucleus (VPM) is a nucleus within the ventral posterior nucleus of the thalamus and serves an analogous somatosensory relay role for the ascending trigeminothalamic tracts as its lateral neighbour the ventral posterolateral nucleus serves for dorsal column–medial lemniscus pathway 2nd-order neurons.
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 ]
