The ventral spinothalamic tract carries "light touch" sensation. There are three neurons that carry the information to the brain. From the cutaneous nerve(s) in the skin to the dorsal root ganglia, then to the dorsal horn in spinal cord, crossing over to the other side and traveling up to the thalamus, and finally from the thalamus to post-central gyrus.
Because the axons of the neuron cross over to the other side of the spinal cord almost immediately, a spinal cord lesion will produce loss of this sensation on the opposite side of the body below where the lesion occurs.
According to one of my medical books, however, light touch can ALSO be carried via the medial lemniscus tract, which doesn't cross until it reaches the brain stem. That being true, light touch could be spared even if there is damage to the ventral spinothalamic tract.
I hope that helps!
Compliments of your friendly MSI :)
What else can I help you with?
The white matter tract in the ventral portion of the mid-brain?
The white matter tract in the ventral portion of the mid-brain is likely referring to the cerebral peduncles. These structures contain fibers connecting the cortex to the brainstem and spinal cord. They are involved in motor coordination and control.
Does paralyzis happen when the spinothalamic tract is severed?
Paralysis does not typically result from severing the spinothalamic tract, as this tract carries sensory information related to pain and temperature. Motor paralysis, which involves voluntary muscle movement, is usually associated with damage to the corticospinal tract, which is responsible for transmitting motor signals from the brain to the spinal cord.
What functional problems in lateral spinothalamic if cut?
If the lateral spinothalamic tract is cut, there will likely be deficits in pain and temperature sensation on the opposite side of the body below the level of the cut. This is because the lateral spinothalamic tract carries pain and temperature information from the body to the brain for processing.
What is related to the spinothalamic tract Thalamus and nociceptors?
The spinothalamic tract is a neural pathway that transmits pain and temperature sensations from the body to the thalamus in the brain. Nociceptors, which are specialized sensory receptors, detect painful stimuli and send signals through peripheral nerves to the spinal cord, where they then ascend via the spinothalamic tract. Once the signals reach the thalamus, they are relayed to higher brain regions for processing and perception of pain. Thus, the spinothalamic tract serves as a crucial conduit linking nociceptive input to thalamic processing.
What does spinothalamic tract do?
The lateral spinothalamic tract is a bundle of sensory axons ascending through the white matter of the spinal cord, carrying sensory information to thebrain. It carries pain and temperature sensory information to the thalamus of the brain

What is the difference between lateral spinothalamic and anterior spinothalamic tracts?
Lateral spinothalamic tract = carry pain and temperature sensationsAnterior spinothalamic tract = carry crude touch and light pressure

What tract conducts impulse from the spinal cord to the thalamus?
to the spinothalamic tract
What tract conveys nerve impulses for crude touch and pressure?
spinothalamic, it is a somatosensory pathway
What tract might be damaged if there is diminished pain perception?
The spinothalamic tract is damaged.
What is the function of lateral spinothalamic tract?
The function of this tract is to detect pain.
What are the origins for lateral spinothalamic and anterior spinothalamic tracts?
Lateral reticulospinal tract : It arises from the nuclei of reticular formation of the brain stem (mainly medulla)Medial reticulspinal tract : It arises from the nuclei of reticular formation of the brain stem (mainly pons)

What are nueral tracts that convey life saving information to the brain concerning burning pain?
The spinothalamic tract carries information about burning pain to the brain. This tract is responsible for transmitting sensory information related to temperature, pain, and crude touch from the body to the brain. If there is a burning pain sensation, signals travel along this pathway to alert the brain quickly for appropriate responses.
Does the spinothalamic tract have somatotopic organisation?
yes the spinothalamic tract is highly organised somatotopically. In the cervical segments (which contain fibres from all levels of the body), fibres from lower levels of the cord (conveying info from legs) are found laterally within the tract; fibres from higher levels (conveying info from arms) are found medially within the tract. i.e ARMS = MEDIAL LEGS = LATERAL Hope that helps =)
