El cerebro y la conducta Neuroanatoma para psiclogos Segunda edicin The shape of the gland resembles a pine cone, which gives it its name. In many vertebrates, the habenula is divided into the medial habenula (MHb) and the lateral habenula (LHb). The vertebrate habenulae (Hb) is an evolutionary conserved dorsal diencephalic nuclear complex that relays information from limbic and striatal forebrain regions to the ventral midbrain. The habenula is a complex nucleus composed of lateral and medial subnuclei, which connect between the limbic forebrain and midbrain. 5.7 CEREEBROSPINAL FLUID-Cerebrospinal fluid (CSF) is a clear, colorless liquid that protects the brain and spinal cord from chemical and physical injuries.
