Sensory cortex

Sensory Cortex

The Sensory cortex is a part of the cerebral cortex responsible for processing sensory information within the human brain. It is divided into primary and secondary areas, each dealing with different types of sensory data.

Primary Sensory Cortex

The Primary sensory cortex is the region of the cerebral cortex that first receives sensory input directly from the thalamus. This area includes the primary auditory cortex, primary somatosensory cortex, and primary visual cortex.

Primary Auditory Cortex

The Primary auditory cortex is the part of the sensory cortex that processes auditory information in humans and other vertebrates. It is located in the temporal lobe.

Primary Somatosensory Cortex

The Primary somatosensory cortex is located in the postcentral gyrus, and is part of the sensory cortex that is involved in processing somatic sensations. These sensations arise in 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.

Primary Visual Cortex

The Primary visual cortex (V1) is the most studied visual area in the brain. In mammals, it is located in the posterior pole of the occipital lobe and is the simplest, earliest cortical field of view.

Secondary Sensory Cortex

The Secondary sensory cortex is the region of the sensory cortex that receives direct projections from the primary sensory cortex. These areas include the secondary auditory cortex, secondary somatosensory cortex, and secondary visual cortex.

Secondary Auditory Cortex

The Secondary auditory cortex is one of the main areas of the auditory system, involved in the processing of sound.

Secondary Somatosensory Cortex

The Secondary somatosensory cortex is involved in the processing of somatic sensations, including touch, proprioception, nociception, and temperature.

Secondary Visual Cortex

The Secondary visual cortex (V2) is the second major area in the visual cortex, and the first region within the visual association area. It receives strong feedforward connections from V1 (primary visual cortex).
