Study Notes
Somatosensory Area (SI)
- Located in the postcentral gyrus of the parietal lobe in the brain.
- Responsible for processing tactile information, including touch, pain, and temperature.
Somatosensory Association Cortex
- Involved in further processing sensory input from the primary somatosensory area.
- Integrates sensory information to help understand spatial relationships, object recognition, and interpreting sensory experiences.
Primary Auditory Area (A1)
- Situated in the superior temporal gyrus of the temporal lobe.
- Functions as the main hub for processing sound information, including pitch and volume.
Secondary Auditory (Association) Area (A11)
- Located adjacent to the primary auditory area in the temporal lobe.
- Responsible for more complex processing of auditory information, such as the recognition of sounds, understanding language, and music perception.
Perception of Cutaneous and Proprioceptive Sensations
- The primary somatosensory area perceives sensations from the opposite half of the body.
- This means that sensations on the right side of the body are processed in the left hemisphere and vice versa.
