	Trigeminal nerve - Wikipedia, the free encyclopedia
		Touch/position information from the body is carried to the thalamus by the medial lemniscus; touch/position information from the face is carried to the thalamus by the trigeminal lemniscus.
		The main nucleus is analogous to the dorsal column nuclei (the gracile and cuneate nuclei) of the spinal cord, which contain a touch/position map of the rest of the body.
		From the main trigeminal nucleus, secondary fibers cross the midline and ascend in the trigeminal leminiscus to the contralateral thalamus.

		A. The inferior colliculus is enveloped by fibers of the lateral leminiscus.
		Excitation of the medial rectus muscle in convergence is most often ipsilaterally controlled by the occulomotor while it is contralaterally controlled by horizontal gaze.
		E. It is excitatory to contralateral flexors and inhibitory to contralateral extensors and is responsible for the swing phase of locomotion.

		Internal arcuate fibers  crosses to the opposite side and enter medial lemniscuses and pass through mid brain and ends in ventral posterolateral nucleus of the thalamus, second relay  third order neuron  axons pass through the posterior limb of internal capsule and ends in post central gyrus.
		Spinal leminiscus then ascends up to join the medial leminiscus in the upper part of medulla oblongata and finally terminate in the ventral posterolateral nucleus of the thalamus.
		At the upper border of pons and mid brain this tract along with lateral spinothalamic tract and internal arcuate fibres run in the medial leminiscus and terminate in the ventral posterolateral nucleus of the thalamus.

		Areas of hyperintense signal in gray and white matter were imaged in 55% of subjects who rated their daily fatigue as moderate or higher but were not imaged in any of the subjects reporting mild daily fatigue (Figure 2).
		Small discrete areas of HS were imaged in the putamen, the rostral reticular formation and in the right medial leminiscus.
		Multiple punctate areas of HS were imaged in the periventricular and deep white matter and discrete areas of HS were seen in the centrum semiovale that were 5.0 mm2 to 24.0 mm2 in area (Figure 3).

		Axons from these nuclei form the medial leminiscus which terminates in the thalamus.
		The medial leminiscus is connected, via the anterior pretectal nucleus, to the periaqueductal grey area in the midbrain at the upper end of the opioid peptide mediated serotinergic descending inhibitory system (Baldry 1993).
		Neurogenic pain is much less responsive than nocigenic pain to the electroanalgesia techniques of evoking activity in endogenous opioid peptide and non-opioid peptide mediated pain modulating mechanisms.

		The “alerting” information from your medial leminiscus to the thalamus carries one version of what’s happening to your body, one version of why you’re falling.
		If your leminiscus, thalamus, vestibular system, cerebellum, pyramidal tract, or basal ganglia are affected by disease, the information your cortex receives will be flawed, and its response will be flawed—you will find yourself on the floor.
		The medial leminiscus is affected in pernicious anemia, resulting from a deficiency of vitamin B-12 and/ or folate.

		Department of Physiology, University College London, UK Neurons in the medial superior olive (MSO) receive inputs from both the ipsilateral and contralateral cochlear nuclei and are thought to act as coincidence detectors, firing maximally when ipsilateral and contralateral inputs arrive synchronously.
		Recently however, both of these theories have been challenged by the finding that the internal delay appears to be determined by glycinergic input to the MSO (Brand et al., 2002).
		Responses of delay sensitive cells in the inferior colliculus (IC) and dorsal nucleus of the lateral leminiscus (DNLL) were obtained from anaesthetised guinea pigs using a noise stimulus subjected to both interaural time and interaural phase delays (Yin et al., 1987).

		Therefore, the bass clef [low frequency] is closer to the ear, and the treble clef [high frequency] is more medial.

		Small discrete or multiple punctuate areas of hyper intense signal (HS) in the reticular formation, putamen, medial leminiscus or white matter tracts were imaged in 55% of the subjects reporting high fatigue and in none those reporting low fatigue.
		The presence of HS significantly correlated with fatigue severity and subjective problems in attention, concentration, staying awake, recent memory and thinking clearly.
		A single discrete area of HS was imaged in the rostral reticular formation in one subject and in the right medial leminiscus in another.

		Anesthesia should not cause assymetric loss of near-field, cortical signals.
		The initial marked attenuation without change in latency of cortical signals following L. median stim with intact P14 and N18 far-field cerebral responses (thought to arise from the medial leminiscus and meso-thallamic junction, respectively) is consistent with difficulty rostral to this point.
		Far field signals look stable on the last trace but both corticals with marked attenuation.
