anterior nuclear group The anterior nuclei of thalamus (or anterior nuclear group) are a collection of nuclei at the rostral end of the dorsal thalamus. They comprise the anteromedial, anterodorsal, and anteroventral nuclei. Inputs and outputs The anterior nuclei recei ...

magnocellular part The magnocellular red nucleus (mRN or mNR or RNm) is located in the rostral midbrain and is involved in motor coordination. Together with the parvocellular red nucleus, the mRN makes up the red nucleus. Due to the role it plays in motor coordin ...

paratenial nucleus The paratenial nucleus, or parataenial nucleus ( la, nucleus parataenialis), is a component of the midline nuclear group in the thalamus. It is sometimes subdivided into the nucleus parataenialis interstitialis and nucleus parataenialis parvocellu ...
** paraventricular nucleus of thalamus **
reuniens nucleus The nucleus reuniens is a region of the thalamic midline nuclear group. In the human brain, it is located in the interthalamic adhesion (''massa intermedia''). The nucleus reuniens receives afferent input from a large number of structures, main ...

rhomboidal nucleus Traditionally, in two-dimensional geometry, a rhomboid is a parallelogram in which adjacent sides are of unequal lengths and angles are non-right angled. A parallelogram with sides of equal length (equilateral) is a rhombus but not a rhomboid. ...

central medial nucleus In the anatomy of the brain, the centromedian nucleus, also known as the centrum medianum, (CM or Cm-Pf) is a part of the intralaminar thalamic nuclei (ITN) in the thalamus. There are two centromedian nuclei arranged bilaterally. In humans, it c ...
