Diencephalic syndrome, or Russell's syndrome, is a rare neurological disorder seen in infants and children and characterised by failure to thrive and severe emaciation despite normal or slightly decreased caloric intake.
The optic nerve (CNII) attaches to the diencephalon. The optic nerve is a sensory (afferent) nerve responsible for vision and sight; it runs from the eye through the optic canal in the skull and attaches to the diencephalon.
The epithalamus also serves as a connecting point for the dorsal diencephalic conduction system, which is responsible for carrying information from the limbic forebrain to limbic midbrain structures. [ 4 ] [ 5 ] Some functions of its components include the secretion of melatonin from the pineal gland ( circadian rhythms ), regulation of motor ...
The stria medullaris (SM), (Latin, furrow and pith or marrow) is a part of the epithalamus and forms a bilateral white matter tract of the initial segment of the dorsal diencephalic conduction system (DDCS). It contains afferent fibers from the septal nuclei, lateral preoptico-hypothalamic region, and anterior thalamic nuclei to the habenula.
At the interface between the expression domains of Fez and Otx, the mid-diencephalic organizer (MDO, also called the ZLI organiser) is induced within the thalamic anlage. The MDO is the central signalling organizer in the thalamus. A lack of the organizer leads to the absence of the thalamus.
Due to humans having an upright posture, however, our nervous system is considered to bend about 90°. This is considered to occur at the junction of the midbrain and diencephalon (the midbrain-diencephalic junction). Thus, the terminology changes at either side of the midbrain-diencephalic junction.

Like other areas of the thalamus, particularly other relay nuclei, the LGN likely helps the visual system focus its attention on the most important information. That is, if you hear a sound slightly to your left, the auditory system likely "tells" the visual system , through the LGN via its surrounding peri-reticular nucleus, to direct visual ...
