2023年11月9日 · The diencephalon is the central portion of the brain located around the third ventricle, superior to the brainstem (medulla, pons and midbrain), and inferior to the corpus callosum and cerebral cortex.

The diencephalon is the region of the embryonic vertebrate neural tube that gives rise to anterior forebrain structures including the thalamus, hypothalamus, posterior portion of the pituitary gland, and the pineal gland. The diencephalon encloses a cavity called the third ventricle.

2025年1月22日 · The diencephalon is an integral part of the brain that serves as a relay center for sensory and motor information and regulates autonomic and endocrine functions. It plays a critical role in maintaining homeostasis, processing sensory inputs, controlling emotions, and coordinating motor functions.

2024年9月26日 · It is divided into four main structures—the thalamus, hypothalamus, epithalamus, and subthalamus. The diencephalon is involved in many crucial bodily functions including coordinating with the endocrine system to release hormones, relaying sensory and motor signals to the cerebral cortex, and regulating circadian rhythms (the sleep wake cycle).

The diencephalon is deep beneath the cerebrum and constitutes the walls of the third ventricle. The three major regions of the diencephalon are the thalamus, the hypothalamus, and the epithalamus (Figure 1).

The diencephalon, which gives rise to the optic nerve, can be divided into four regions: thalamus, hypothalamus, subthalamus and epithalamus. A drawing of a median view of the rostral brainstem is shown below. Components of the diencephalon are labeled in bold.

2024年9月24日 · The diencephalon is connected above and in front of the cerebral hemispheres behind the mid-brain. Its upper surface is concealed by the corpus callosum and is covered by a fold of pia mater, named the tela choroidea of the third ventricle. Inferiorly, it reaches the base of the brain. It comprises:
