In that study, the functioning of the dorsal column-medial lemniscal pathway was assessed using vibration, joint position, and touch and the functioning of the spinothalamic pathway using pain and temperature [12].
reported that "Pathophysiologically, a disinhibition of the phylogenetically old pain pathway that passes through the intralaminar thalamic nuclei and projects to the anterior cingulate cortex and an imbalance of the putative modulatory action of the lemniscal system on the pain pathways have been postulated." It has also been proposed that the hyperactivity of the differentiated parietal neurons as a result of their disconnection leads to spontaneous painful sensations [8].
Neural inputs evoked by SMT stimuli via various receptors in muscles, tendons, and joints may ascend to the somatosensory areas of the brain through the medial lemniscal system.
At least three parallel pathways carry ascending tactile information to the cortex: the lemniscal, extralemniscal and paralemniscal pathways, which are relayed by distinct regions in the thalamus, the ventral posteromedial nucleus in the lemniscal pathway and the posterior medial nucleus in the extralemniscal and paralemniscal pathway, respectively (3,4).
(2009) Septal neurons in barrel cortex derive their receptive field input from the lemniscal pathway.
(6) This pathway consists of the dorsal column--medial lemniscal, and thalamo--cortical sensory systems.
In the second stage of plastic reorganization the new auditory cortex neuronal restyling is punctuated and limited in function and extension by brain network gating systems; in case of a lack of gating system or in case of the presence of facilitating factors, the neuronal restyling affects several auditory (lemniscal and extralemniscal) and nonauditory pathways, leading to modifications in the location and crossmodal interplay of specific information processes.
The classical signs of MMI consist of contralateral hemiparesis, lemniscal sensory loss, ipsilateral lingual palsy1 and contralateral pharyngeal palsy.2 Patients with bilateral MMI syndrome often present with tetraparesis, bilateral loss of deep sensation, dysphagia and speech difficulties.
Patients present with eye movement disturbances, lemniscal and spinothalamic sensory deficits, and ipsilateral palsies of cranial nerves V, VI, and VII.
'Thumb localizing test' for detecting a lesion in the posterior column-medial lemniscal system.
Las citoquinas y los mediadores de la inflamacion activan receptores perifericos del dolor, sus axones se proyectan al asta dorsal de la medula, donde hacen sinapsis con el tracto lemniscal, el cual lleva senales de dolor al talamo y la corteza somatosensorial.
(11) Cases were identified in which the pyramidal tract did not extend into the spinal cord and the medial lemniscal tracts did not separate.
