  2. Nucleus (neuroanatomy) - Wikipedia

    en.wikipedia.org/wiki/Nucleus_(neuroanatomy)

    In neuroanatomy, a nucleus (pl.: nuclei) is a cluster of neurons in the central nervous system, [1] located deep within the cerebral hemispheres and brainstem. [2] The neurons in one nucleus usually have roughly similar connections and functions. [ 3 ]

  3. Caudal pontine reticular nucleus - Wikipedia

    en.wikipedia.org/wiki/Caudal_pontine_reticular...

    The caudal pontine reticular nucleus or nucleus reticularis pontis caudalis is a portion of the reticular formation, composed of gigantocellular neurons. In rabbits and cats it is exclusively giant cells, however in humans there are normally sized cells as well. In rodents, it has been shown to play a role in the acoustic startle response.

  4. Dorsal column nuclei - Wikipedia

    en.wikipedia.org/wiki/Dorsal_column_nuclei

    The gracile nucleus is medial to the cuneate nucleus. [5] Its neurons receive afferent input from dorsal root ganglia sensory neurons of the lower torso and the lower limbs . [ 5 ] The gracile nucleus and gracile fasciculus carry epicritic , kinesthetic , and conscious proprioceptive information from the lower part of the body (below the level ...

  5. Thalamic reticular nucleus - Wikipedia

    en.wikipedia.org/wiki/Thalamic_reticular_nucleus

    Its function is modulatory on signals going through the thalamus (and the reticular nucleus). The thalamic reticular nucleus receives massive projections from the external segment of the globus pallidus, thought to play a part in disinhibition of thalamic cells, which is essential for initiation of movement (Parent and Hazrati, 1995). [9]

  6. Suprachiasmatic nucleus - Wikipedia

    en.wikipedia.org/wiki/Suprachiasmatic_nucleus

    [1] [3] The neuronal and hormonal activities it generates regulate many different body functions in an approximately 24-hour cycle. The SCN also interacts with many other regions of the brain. It contains several cell types, neurotransmitters and peptides , including vasopressin and vasoactive intestinal peptide .

  7. Raphe nuclei - Wikipedia

    en.wikipedia.org/wiki/Raphe_nuclei

    In order from caudal to rostral, the raphe nuclei are known as the nucleus raphe obscurus, the nucleus raphe pallidus, the nucleus raphe magnus, the nucleus raphe pontis, the median raphe nucleus, dorsal raphe nucleus, caudal linear nucleus. [4] In the first systematic examination of the raphe nuclei, Taber et al..

  8. HVC (avian brain region) - Wikipedia

    en.wikipedia.org/wiki/HVC_(avian_brain_region)

    HVC is located in the caudal nidopallium.It projects to the song motor pathway via the robust nucleus of the arcopallium (RA) and to the Anterior Forebrain Pathway via the basal ganglia nucleus Area X. [1] It receives recurrent motor activity through the thalamic nucleus Uvaformis (Uva) and input from the auditory system through projections from the caudalateral mesopallium (CMM) and through ...

  9. Caudate nucleus - Wikipedia

    en.wikipedia.org/wiki/Caudate_nucleus

    The caudate nucleus is one of the structures that make up the corpus striatum, which is part of the basal ganglia in the human brain. [1] Although the caudate nucleus has long been associated with motor processes because of its role in Parkinson's disease, [2] [clarification needed] [3] it also plays important roles in nonmotor functions, such as procedural learning, [4] associative learning ...
