What is the function of the somatic sensory area?

The somatosensory cortex is a region of the brain which is responsible for receiving and processing sensory information from across the body, such as touch, temperature, and pain.

What does somatic sensory area do?

The primary somatosensory cortex is responsible for processing somatic sensations. These sensations arise from receptors positioned throughout the body that are responsible for detecting touch, proprioception (i.e. the position of the body in space), nociception (i.e. pain), and temperature.

What is the function of the somatic sensory area what lobe is it located in?

Parietal Love: Primary Somatosensory Area

The primary somatosensory area in the human cortex is located in the postcentral gyrus of the parietal lobe. This is the main sensory receptive area for the sense of touch. Like other sensory areas, there is a map of sensory space called a homunculus at this location.

What is the function of the motor cortex?

The primary function of the motor cortex is to generate signals to direct the movement of the body. It is part of the frontal lobe and is anterior to the central sulcus. It consists of the primary motor cortex, premotor cortex, and the supplementary motor area.

What is the function of the secondary somatosensory cortex?

The secondary somatosensory cortex is believed to be involved in tactile object recognition and memory. It is suggested that whilst the primary area receives peripheral sensory information, it requires the secondary area to store, process, and retain this information.

What are the somatic sensory areas of the parietal lobe?

The somatic sensory cortex in humans, which is located in the parietal lobe, comprises four distinct regions, or fields, known as Brodmann’s areas 3a, 3b, 1, and 2. Although area 3b is generally known as the primary somatic sensory cortex (also called SI), all four areas are involved in processing tactile information.

What are the three major somatic sensory pathways?

Structure. A somatosensory pathway will typically consist of three neurons: primary, secondary, and tertiary.

What lobe is the primary somatic motor cortex?

The motor cortex comprises three different areas of the frontal lobe, immediately anterior to the central sulcus. These areas are the primary motor cortex (Brodmann’s area 4), the premotor cortex, and the supplementary motor area (Figure 3.1).

Where is brain motor function?

The cerebellum is located behind the brain stem. While the frontal lobe controls movement, the cerebellum “fine-tunes” this movement. This area of the brain is responsible for fine motor movement, balance, and the brain’s ability to determine limb position.

What are the functions of the three motor cortex within the cerebrum?

The motor cortex is an area within the cerebral cortex of the brain that is involved in the planning, control, and execution of voluntary movements.

What is the function of the primary auditory cortex?

The primary auditory cortex is involved with integrating and processing complex auditory signals, which includes language comprehension. The auditory association cortex is located lateral to the primary auditory cortex and is part of a language reception area known as theWernicke area.

What is the difference between primary and secondary somatosensory cortex?

The primary somatosensory cortex is responsible for receiving the bulk of somatosensory inputs, including touch, temperature, vibration, pressure, and pain, etc. Whereas, the secondary somatosensory cortex is associated with spatial and tactile memory associated with sensory experiences.

What is the sensory association area?

sensory association area an association area around the borders of a primary receiving area, where sensory stimuli are interpreted.

Where is the secondary sensory cortex?

The secondary somatosensory cortex, SII, is located inferiorly – in the pars opercularis of the parietal lobe, which forms part of upper lip of the lateral sulcus (Figure 5.4 & Figure 5.5). SII neurons send their axons to SI, association cortex, motor cortex, and insula (Figure 5.6).
