A lesion localized to a ventral posterolateral in the thalamus will lead to an initial loss of all sensations from the contralateral side of the body, including ...

This is known as Brown–Sequard syndrome or sensory dissociation. Below such a lesion, there is loss of two-point discrimination and proprioception ipsilaterally ...

The finest afferent fibres divide in Lissauer's tract; the larger fibres divide in the dorsal columns. All neurones of the spinothalamic complex receive an ...

The posterolateral tract is a small strand situated in relation to the tip of the posterior column close to the entrance of the posterior nerve roots.

It is responsible for the transmission of pain, temperature, and crude touch to the somatosensory region of the thalamus.

This lesion produces analgesia by interrupting the spinothalamic tract, which is the principal pathway that carries nociceptive information from the spinal ...

Posterolateral tract of Lissauer refers to those segments of the axons of first order neurons in the spinothalamic neuronal pathway.

Lissauer's tract is a pathway formed from the proximal end of small unmyelinated and poorly myelinated fibers in peripheral nerves, which enter at the lateral ...
