Definitions

1. The diencephalon is a part of the forebrain that contains such important structures as the thalamus, hypothalamus, and gland.
2. The diencephalon is a subcortical structure that is made up of the thalamus and the hypothalamus.
3. The diencephalon is a difficult area to observe because it is dorsal and anterior to the midbrain, and lies ventral to the cerebrum.
4. Diencephalon: A region of the brainstem derived from the prosencephalon.
5. Diencephalon : The paired caudal parts of the prosencephalon from which the THALAMUS; HYPOTHALAMUS; EPITHALAMUS; and SUBTHALAMUS are derived.

Diencephalon

1. BrainMaps at UCDavis diencephalon  This neuroanatomy article is a stub.
2. Under the diencephalon forming the cerebral peduncles.
3. The roof-plate of the telencephalon remains thin, and is continuous in front with the lamina terminalis and behind with the roof-plate of the diencephalon.
4. Keyser A (1972) The development of the diencephalon of the Chinese hamster.
5. Ventral diencephalon also reveals cells from the Ptf1a lineage (inset).

Midbrain

1. The diencephalon is located between the cerebrum and the midbrain.
2. This nucleus is part of the thalamic relay system, even though it is located in the rostral midbrain and not the diencephalon (1).
3. The brainstem includes the diencephalon, midbrain, pons, and medulla oblongata.
4. The Basal Ganglia are a group of functionally related Nuclei located bilaterally in the Inferior Cerebrum, DienCephalon and MidBrain.
5. Interpeduncular Nucleus: in caudal midbrain receives input from habenular nuclei of diencephalon.

Structures

1. The diencephalon interconnects with a larger, surrounding array of structures called the limbic system, which is the seat of emotions and memory.
2. Several structures within the diencephalon that we will review include the thalamus, epithalamus, hypothalamus, and pituitary.

Ventricle

1. The diencephalon comprises: (1) the thalamencephalon; (2) the pars mamillaris hypothalami; and (3) the posterior part of the third ventricle.
2. The lateral ventricles communicate with the narrow, slit-shaped third ventricle of the diencephalon.
3. The diencephalon borders on the cerebral cortex, the latreral ventricles and the efibers of the corpus collosum superiorly.
4. Within the diencephalon, the sides of the third ventricle are attached together by an intermediate mass of grey matter.

Mesencephalon

1. The mesencephalon caudally adjoins the pons and rostrally adjoins the diencephalon.
2. Below the diencephalon are the midbrain (or mesencephalon) and the hindbrain (or rhombencephalon).
3. The terms telencephalon, diencephalon, mesencephalon, metencephalon, and myelencephalon denote five distinct embryonic subdivisions.
4. Ventricular system is developed from contributions from the prosencephalon, diencephalon, mesencephalon and rhombencephalon.

Hemispheres

1. Each of these communicates through a small pore with a slitlike third ventricle between the two hemispheres, surrounded by the diencephalon.
2. The major divisions of the human brain are the brainstem, cerebellum, diencephalon, and cerebral hemispheres.
3. The brain has four major parts: the brainstem, the cerebellum, the diencephalon, and the cerebral hemispheres.

Roof

1. The next cavity caudad is the diencephalon the roof of the diencephalon outpockets to sexual an functions (fsh, lh) the adrenal cortex secretions.
2. The floor of the fissure is the roof of the third ventricle and a small part of the dorsal diencephalon.

Geniculate

1. The inferior colliculus, involved in the special sense of hearing sends its inferior brachium to the medial geniculate body of the diencephalon.
2. It is involved in the special sense of vision and sends its superior brachium to the lateral geniculate body of the diencephalon.

Brain Stem

1. The diencephalon is located at the midline of the brain, above the mesencephalon of the brain stem.
2. The diencephalon connects the cerebrum to the brain stem.
3. The brain stem connects the diencephalon to the spinal cord.

Limbic System

1. The limbic system is the ring of cerebral cortex on the medial surface of the hemisphere that encircles the diencephalon.
2. Limbic system: limbic lobe, hippocampal formation, and portions of the diencephalon, especially the mamillary body and anterior thalamic nuclei.

Gland

1. In addition to the pineal gland the diencephalon includes the thalamus, hypothalamus, and mammillary bodies.
2. Induced expression of c-fos in the diencephalon and pituitary gland of goats following transportation -- Maejima et al.

Forebrain

1. Also recognized as the forebrain, the prosencephalon gives rise to the diencephalon and the telencephalon.
2. The forebrain consists of the diencephalon and cerebrum.
3. Last check: 2007-10-10) The section is located in the forebrain, which consists of the telencephalon and diencephalon.

Extends

1. A small part of the diencephalon, the epithalamus, extends rearward from, and slightly higher than, the thalamus.
2. The body is attached to the diencephalon by the pineal stalk, into which te 3rd ventricle extends as the pineal recess.

Walls

1. The diencephalon comprises most of the walls of the third ventricle.
2. The early prosencephalon develops an ocular cup from its ventrolateral walls in the position of the future diencephalon.
3. Early in development, the diencephalon develops 2 pairs of prominent swellings in the walls of the 3rd ventricle.

Hypothalamus

1. The diencephalon lies above the brain stem and embodies the thalamus and hypothalamus.
2. The thalamus, which forms the major part of the diencephalon, receives incoming sensory impulses and routes them to the appropriate higher centers.
3. The hypothalamus is a part of the diencephalon lying next to the thalamus.
4. The thalamus and hypothalamus are parts of the diencephalon, while the amygdala and hippocampus are parts of the cerebral hemispheres.
5. Diencephalon thalamus hypothalamus a functions.

Gray Matter

1. The thalamus is a large body of gray matter at the top of the diencephalon, positioned deep within the forebrain.
2. The upper part of the diencephalon, making up about 80% of its mass, is the thalamus, a small pillow of neural gray matter divided into two egg-shaped lobes.

Thalamus

1. The diencephalon contains the zona limitans intrathalamica as morphological boundary and signalling centre between the prethalamus and the thalamus.
2. The subthalamus, or prethalamus (formerly described as ventral thalamus), is part of the diencephalon.
