ventral posterolateral nucleus การใช้

• Most likely, neurons intrinsic to the ventral posterolateral nucleus make at least some of it.
• It corresponds to the caudal part of the ventral posterolateral nucleus, which receives input from the medial afferents.
• More specifically, its fibers convey crude touch information to the VPL ( ventral posterolateral nucleus ) part of the thalamus.
• From the ventral posterolateral nucleus in the thalamus, sensory information is relayed upward to the somatosensory cortex of the postcentral gyrus.
• The concentration of this chemokine is increased in the ventral posterolateral nucleus of the thalamus where secondary nociceptive neurons make connections with other neurons.
• Secondary axons from the medial lemniscus finally terminate in the ventral posterolateral nucleus ( VPL ) of the thalamus, where they synapse with tertiary neurons.
• The medial lemniscus carries axons from most of the body and synapses in the ventral posterolateral nucleus of the thalamus, at the level of the mamillary bodies.
• Second order neospinothalamic tract neurons carry information from A-delta fibers and terminate at the ventral posterolateral nucleus of the thalamus, where they connect with third order neurons of the somatosensory cortex.
• The axons travel up the rest of the brainstem, and synapse at the thalamus ( at the ventral posterolateral nucleus for sensation from the neck, trunk, and extremities, and at the ventral posteromedial nucleus for sensation from the head ).
• Three electrodes are implanted; two in the ventral posterolateral nucleus of the thalamus which conveys facial sensory information from the left and right whiskers, and a third in the medial forebrain bundle which is involved in the reward process of the rat.
• In humans, temperature sensation enters the spinal cord along the axons of Lissauer's tract that synapse on second order neurons in grey matter of the decussate, joining the spinothalamic tract as they ascend to neurons in the ventral posterolateral nucleus of the thalamus.
• In humans, temperature sensation from thermoreceptors enters the spinal cord along the axons of Lissauer's tract that synapse on second order neurons in grey matter of the decussate, joining the spinothalamic tract as they ascend to neurons in the ventral posterolateral nucleus of the thalamus.
• Axons of the second order neurons cross the midline and terminate in the ventral posteromedial nucleus of the thalamus ( as opposed to the ventral posterolateral nucleus as in the dorsal column-medial lemniscus pathway ) to mediate conscious sensation of pain and temperature from the face, head and neck.
