The thalamus is connected to the cerebral cortex via the thalamocortical radiations. [28] The spinothalamic tract is a sensory pathway originating in the spinal cord. It transmits information to the thalamus about pain, temperature, itch and crude touch.

This tract was historically considered a cephalic division of the medial lemniscus due to the close proximity of the two ascending tracts. [2] Like the medial lemniscus in the dorsal column-medial lemniscus pathway (DCML), that carries mechanosensory information from part of the head and the rest of the body, the trigeminal lemniscus carries ...
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 ...
Sometimes, it is in two parts – and 20% of the time, it is absent. [2] In other mammals, it is larger. In 1889, a Portuguese anatomist by the name of Macedo examined 215 brains, showing that male humans are approximately twice as likely to lack an interthalamic adhesion as are female humans.
The following diagram is provided as an overview of and topical guide to the human nervous system: Human nervous system. Human nervous system – the part of the human body that coordinates a person's voluntary and involuntary actions and transmits signals between different parts of the body.
[2] [3] It overlies the paraventricular nucleus of hypothalamus, [4] and is involved in the secretion of vasopressin. [2] The VOLT monitors the presence of peptides and macromolecules in the bloodstream, and conveys the information to the hypothalamus. [3] It is one of the three sensory circumventricular organs of the brain. [5] The other four ...
Mammillary bodies, and their projections to the anterior thalamus via the mammillothalamic tract, are important for recollective memory. [7] According to studies of rats with mammillary body lesions, damage to the medial mammillary nucleus lead to spatial memory deficits.
