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]
Anatomy
[edit]Subdivisions
[edit]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]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
