The dorsal longitudinal fasciculus (DLF) is a distinctive nerve tract in the midbrain.It extends from the hypothalamus rostrally to the spinal cord caudally, and contains both descending and ascending fibers.
The diencephalon encloses a cavity called the third ventricle. The thalamus serves as a relay centre for sensory and motor impulses between the spinal cord and medulla oblongata, and the cerebrum. It recognizes sensory impulses of heat, cold, pain, pressure etc. The floor of the third ventricle is called the hypothalamus.
The epithalamus (pl.: epithalami) is a posterior segment of the diencephalon. [3] The epithalamus includes the habenular nuclei, the stria medullaris, the anterior and posterior paraventricular nuclei, the posterior commissure, and the pineal gland. [2]

The forebrain separates into two vesicles – an anterior telencephalon and a posterior diencephalon. The telencephalon gives rise to the cerebral cortex, basal ganglia, and related structures. The diencephalon gives rise to the thalamus and hypothalamus. The hindbrain also splits into two areas – the metencephalon and the myelencephalon. The ...
Its inferior brachium (arm-like process) reaches to the medial geniculate nucleus of the diencephalon. The superior colliculus is positioned above the inferior colliculus, and marks the rostral midbrain. It is involved in the special sense of vision and sends its superior brachium to the lateral geniculate body of the diencephalon.
The fields of Forel is a complex region in the posterior subthalamus, consisting of a concentrated collection of bundles of fibers. [1] The tracts formed include the thalamic fasciculus that includes the ansa lenticularis and lenticular fasciculus, cerebellothalamic tracts, and pallidothalamic tracts.
In neuroanatomy, topographic map is the ordered projection of a sensory surface (like the retina or the skin) or an effector system (like the musculature) to one or more structures of the central nervous system. Topographic maps can be found in all sensory systems and in many motor systems.
