This nucleus establishes several neuronal pathways with different regions within the brain: Ventral posterolateral (VPL) Medial lemniscal pathway (afferent) Spinothalamic pathway (afferent) Ventral posteromedial : Trigeminothalaimc pathway (afferent) Overall ventral posterior nucleus 1. Areas 1 and 3b of the primary somatic sensory cortex (efferent) 2. Second somatic sensory cortex (efferent) 3. Insular cortex (efferent) The trigeminothalamic pathway brings temperature and pain sensations from the face, head and neck. In turn, the medial lemniscal and spinothalamic pathways bring sensory information from the skin and joints. Neurons receiving the inputs are organised into curved lamellae, with one lamella usually representing one region of the body. Within one lamella, different regions receive inputs distinguished by the level of sensorial “depth”. For instance, when referring to the hand, the anterodorsal part receives information from deep stimuli such as joint, tendon and muscle movement. These are the deepest source. The ventral part receives more superficial stimuli from tapping, while the neurons located between these two parts receive the most superficial inputs, such as cutaneous touch. The efferent fibers running to the somatosensory cortex pass through the posterior limb of the internal capsule and corona radiata. This illustrates their involvement in relaying sensory sensations for conscious identification. #VentralPosteriorNucleus #thalamusanatomy #usmleanatomy #thalamus #thalamicnuclei #thalamicnucleus #thalamususmle #
