Ventral Nuclear Group

The ventral nuclear group is a collection of nuclei on the ventral side of the thalamus. According to MeSH, it consists of the following:

  • ventral anterior nucleus
  • ventral lateral nucleus
  • ventral posterior nucleus
Human brain: diencephalon (TA A14.1.08, GA 9.807)
Epithalamus
Surface
  • Pineal body
  • Habenula
  • Habenular trigone
  • Habenular commissure
Grey matter
  • Pretectal area
  • Habenular nuclei
  • Subcommissural organ
Thalamus
Surface
  • Stria medullaris of thalamus
  • Thalamic reticular nucleus
  • Taenia thalami

  • Ventromedial
  • Dorsomedial
White matter
  • afferent
    • SN → Medial forebrain bundle
  • efferent
    • Mammillothalamic fasciculus → AN, Stria terminalis → Amygdala, Dorsal longitudinal fasciculus → SC
Pituitary
  • Posterior is diencephalon, but anterior is glandular

Famous quotes containing the words nuclear and/or group:

    “The reduction of nuclear arsenals and the removal of the threat of worldwide nuclear destruction is a measure, in my judgment, of the power and strength of a great nation.”
    —Jimmy Carter (James Earl Carter, Jr.)

    “No group and no government can properly prescribe precisely what should constitute the body of knowledge with which true education is concerned.”
    —Franklin D. Roosevelt (1882–1945)
