The fibers that project to the tectum are known as the spinotectal fibers. [5] The spinotectal tract fibers project to the superior colliculus. Where they synapse onto cells of the deeper superior colliculus they are activated by noxious stimuli. [1]

Functionally, the spinotectal tract conveys sensory input—including nociceptive stimuli—to the superior colliculus, facilitating spinovisual reflexes. For instance, it aids in directing eye movements toward a visual or painful stimulus (via tectobulbar tract) and coordinating neck movements towards the stimulus (via the tectospinal tract ...

2023年7月26日 · It is a sensory tract that transmits information from the skin to the thalamus in the brain. The anterolateral system is composed of: The anterior and lateral spinothalamic tracts. The former helps localize crude touch and pressure, the latter painful or temperature sensation.

2020年3月1日 · This is where the spinotectal tract (also called the spinomesencephalic tract) comes in. It plays an important role in the control and inhibition of pain. It originates in the spinothalamic tract and terminates in the inferior and superior colliculi …

2023年8月16日 · The spinotectal tract (also known as the spinomesencephalic tract) is responsible for spinovisual reflexes, allowing you to turn your head and gaze toward a visual stimulus (e.g., a sudden flash of light). The fibers cross the spinal cord to …

A pain researcher wants to make a lesion to the Spinothalamic tract so that his subjects feel no pain and temperature sensation from the right leg, but leaves pain and temperature sensation rostral to the arm.

2022年9月13日 · Here we have comprehensively reviewed the key literature detailing the general structure, configuration of tracts, the cytoarchitecture of Rexed's laminae, and the neurochemistry at the spinal segmental level.
