Sensory information is transported to a specific area of ​​the brain such as the visual cortex (located in the occipital lobe), the auditory cortex (located in the temporal lobe), and the somatosensory cortex (located in the parietal lobe). The somatosensory system leads to the primary somatosensory cortex, located in the postcentral gyrus, where touch, pressure, pain, sensation of movement, and proprioception are experienced. Electrical impulses traveling through the spinal cord travel along ascending sensory tracts called the dorsal column tract and spinothalamic tract. The spinothalamic tract is a sensory pathway from the skin consisting of two pathways: lateral spinothalamic and anterior spinothalamic. The lateral spinothalamic tract carries sensory information for pain (nociception) and temperature while the anterior spinothalamic tract carries sensory information for rough, nondiscriminatory touch to the brain. The dorsal column section, on the other hand, is responsible for proprioception, fine touch, two point discrimination and vibrations coming from the skin and mechanoreceptors. The ascending sensory tracts in the spinal cord use three different neurons to transmit information from the receptor to the brain through the spinal cord: primary afferent neurons, second-order neurons, and thalamic neurons. Primary afferent neurons detect the stimulus, for example mechanoreceptors in the skin are sensitive to changes in pressure and fire an action potential. Primary afferent neurons have their cell bodies in the dorsal root ganglion and in an axon that projects to the spinal cord. The dorsal root ganglion contains many sensory cell bodies for different sensory modalities. The action potential reaches the cell body in the dorsal root ganglion and then the second-order neurons. Second-order neurons originating from the nuclei transmit information to the thalamus and their axons pass through the medulla oblongata: this is known as decussation. Thalamic neurons travel upward to the somatosensory cortex where axons form a synapse with the primary somatosensory cortex and sensory information is sent to the cortex via the thalamus. The ascending tracts of the spinal cord have different paths. The dorsal column pathway has sections that travel through the medial lemniscus. While the spinothalamic tract has its own ascending path. Both ascending sensory tracts transmit their information to the cerebral cortex via the axons of the thalamus. The somatosensory cortex is part of the cerebral cortex"
