Hindbrain (rhombencephalon)

Embryonic vertebrate subdivisions of the developing human brain
hindbrain or rhombencephalon is a developmental categorization of portions of the central nervous system in vertebrates. It includes the medulla, pons, and cerebellum.

Limbic system

The limbic system, also known as the paleomammalian cortex, is a set of brain structures located on both sides of the thalamus, immediately beneath the medial temporal lobe of the cerebrum primarily in the midbrain.[1] The classification of structures as part of the limbic system is historical and originates from the position of the structures at the boundary between two functionally distinct components (hence, the name limbus, meaning border) and the structures' shared roles in emotional processes (see limbic system for more details). Hence, there is overlap of structures in the limbic system and in other classifications of brain structures. The following areas have been considered part of the limbic system.[2][3]

  • Cortical areas:
  • Subcortical areas:
    • Septal nuclei: a set of structures that lie in front of the lamina terminalis, considered a pleasure zone
    • Amygdala: located deep within the temporal lobes and related with a number of emotional processes
    • Nucleus accumbens: involved in reward, pleasure, and addiction
  • Diencephalic structures:
    • Hypothalamus: a center for the limbic system, connected with the frontal lobes, septal nuclei, and the brain stem reticular formation via the medial forebrain bundle, with the hippocampus via the fornix, and with the thalamus via the mammillothalamic fasciculus; regulates many autonomic processes
    • Mammillary bodies: part of the hypothalamus that receives signals from the hippocampus via the fornix and projects them to the thalamus
    • Anterior nuclei of thalamus: receive input from the mammillary bodies and involved in memory processing

Other areas that have been included in the limbic system include the:
