What carry sensory information to the brain?
The dorsal column system (sometimes referred to as the dorsal column–medial lemniscus) and the spinothalamic tract are two major pathways that bring sensory information to the brain (Figure 1).

Which type of nerves carry sensory information from the body to the brain?
Sensory nerve fibers carry sensory information (about body position, light, touch, temperature, and pain) to the brain from other parts of the body. The sensory nerve fibers in each sensory nerve root carry information from a specific area of the body, called a dermatome (see figure Dermatomes.
Where is sensory information processed in the brain?
Sensory areas are the areas of the brain that receive and process sensory information. The cerebral cortex is connected to various subcortical structures such as the thalamus and the basal ganglia. Most sensory information is routed to the cerebral cortex via the thalamus.
Which section of the cerebrum is involved with sensory information?
parietal lobe
The parietal lobe is involved with sensory processes, attention, and language. Damage to the right side of the parietal lobe can result in difficulty navigating spaces, even familiar ones.
What contains only fibers of sensory neurons?
A nerve contains bundles of nerve fibers, either axons or dendrites, surrounded by connective tissue. Sensory nerves contain only afferent fibers, long dendrites of sensory neurons. Motor nerves have only efferent fibers, long axons of motor neurons. Mixed nerves contain both types of fibers.
What is in the sensory system?
A sensory system consists of sensory receptors, neural pathways, and parts of the brain involved in sensory perception. Commonly recognized sensory systems are those for vision, hearing, somatic sensation (touch), taste and olfaction (smell).
What are nerve fibers?
A nerve fiber is a long process of nerve cell (neurone) called the axon. The nerve cell’s body is anatomically situated in the central nervous system or within the ganglia of the peripheral nervous system. Each peripheral nerve consists of parallel bundles of nerve fibers, called nerve fascicles.
What are sensory nerves?
A sensory nerve is really a collection of long dendrites carrying messages to the central nervous system from the periphery.
What part of the cortex processes the information from our eyes?
occipital lobe
The occipital lobe is located at the very back of the brain, and contains the primary visual cortex, which is responsible for interpreting incoming visual information.
What is sensory information processing?
Sensory processing is defined as the organization of sensory information from the body and the external world that allows a person to interact effectively with their physical and social environments (Ayres, 2005; From: Encyclopedia of Infant and Early Childhood Development (Second Edition), 2020.
What do commissural fibers do?
Commissural fibers connect an area in one hemisphere with an area in the opposite hemisphere. The corpus callosum is the largest set of commissural fibers in the brain and is a pathway of crucial importance to speech-language functions (Fig. 2-10, B).

Where are sensory neurons located in the spinal cord?
As the spinal nerve nears the spinal cord, it splits into dorsal and ventral roots. The dorsal root contains only the axons of sensory neurons, whereas the ventral roots contain only the axons of the motor neurons.
Where are sensory cortical areas located in the brain?
Whereas the sensory cortical areas are located in the occipital, temporal, and parietal lobes, motor functions are largely controlled by the frontal lobe. The most anterior regions of the frontal lobe—the prefrontal areas—are important for executive functions, which are those cognitive functions that lead to goal-directed behaviors.
Where do the axons go to receive sensory information?
Other axons go to either the chief sensory nucleus in the pons or the mesencephalic nuclei in the midbrain. These nuclei receive information like that carried by the dorsal column system, such as touch, pressure, vibration, and proprioception.
