Anatomical terms of neuroanatomy |
The ventral posterolateral nucleus (VPL) is a nucleus of ventral posterior nucleus of the thalamus. [1] It relays sensory information from the second-order neurons of the neospinothalamic tract and medial lemniscus (of the posterior column-medial lemniscus pathway) which synapse with in the third-order neurons in the nucleus. These then project to the somatosensory cortex in the postcentral gyrus.[ citation needed]
There is uncertainty regarding the location of VMpo, as determined by spinothalamic tract (STT) terminations and staining for calcium-binding proteins, and several authorities do not consider its existence as being proved. [1]
The nucleus ventralis posterior lateralis pars oralis (VPLo) is a subdivision of the ventral posterolateral thalamus which has substantial projections to the motor cortex. [2]
