The mammillotegmental fasciculus (mammillotegmental tract, or mammillotegmental bundle of Gudden) is a small bundle of efferent fibers from the hypothalamus running from the mammillary body to the tegmentum. [1]
Axons divide within the gray matter; the thicker fibres form the MTT while the finer branches descend as the mammillotegmental fasciculus. [3] The MTT spreads fan-like as it terminates in the medial dorsal nucleus. [3] The axons from these nuclei form part of the thalamocortical radiations. [6]

The axons from the first-order neurons form the ascending tracts of the gracile fasciculus, and the cuneate fasciculus (the dorsal columns) which synapse on the second-order neurons in the gracile nucleus and the cuneate nucleus known together as the dorsal column nuclei; axons from these neurons ascend as the internal arcuate fibers; the ...
The gracile nucleus and gracile fasciculus carry epicritic, kinesthetic, and conscious proprioceptive information from the lower part of the body (below the level of T6 in the spinal cord). Because of the large population of neurons in the gracile nucleus they give rise to a raised area called the gracile tubercle on the posterior side of the ...
Association fibers are axons (nerve fibers) that connect cortical areas within the same cerebral hemisphere. [1]In human neuroanatomy, axons within the brain, can be categorized on the basis of their course and connections as association fibers, projection fibers, and commissural fibers. [1]
White matter tracts within a human brain, as visualized by MRI tractography. A nerve tract is a bundle of nerve fibers connecting nuclei of the central nervous system. [1] [2] [3] In the peripheral nervous system, this is known as a nerve fascicle, and has associated connective tissue.
