formerly denoting specifically the somatic sensory cortex, but now used to refer collectively to the somatic sensory, auditory, visual, and olfactory regions of the cerebral cortex.

Formerly denoting specifically the somatic sensory cortex, but now used to refer collectively to the somatic sensory, auditory, visual, and olfactory regions of the cerebral cortex.

sensory cortex

An area on the outer layer (cortex) of the CEREBRUM through the stimulation of which consciousness of sensation is mediated. The sensory cortex for pressure, pain, taste and temperature lies immediately behind the motor cortex on the side of each cerebral hemisphere, about half way back. The cortex for visual sensation is at the back, and that for sound is in the temporal lobes on either side.

Sensory afferents influence M1 either directly through the intracortical connections between the primary sensory cortex (S1) and M1 or through thalamocortical pathways that reach M1 (14,15).
For our purpose, the observation that ILI is required to register information in experience is vital, first because it means that the form of information in the sensory cortex, digital information, is not the form of information in experience, and second because just such a linear transformation would be required to convert the digital information in a sensory cortex into the kind of information, by which a critical instability on the cortex could represent it in experience.
When Copeland was 27, UPMC researchers implanted four tiny, grain-sized electrodes in his brain, two in the motor cortex and the other two in the sensory cortex.
Nearly ten years following his accident, after agreeing to participate in clinical trials, Nathan underwent surgery to have four microelectrode arrayseach about half the size of a shirt buttonplaced in his brain, two in the motor cortex and two in the sensory cortex regions that correspond to feeling in his fingers and palm.
1] This system comprises the brain and the areas in the brain that are intricately involved with our sensory experience of our surroundings--the thalamus and its nuclei that act as major relay centres for the information transferred to the sensory cortex from all the receptive organs in our bodies.
The brain is, in fact, a heterogeneous machine, he said, consisting of structures such as the frontal lobe, cerebellum, motor cortex, sensory cortex, temporal lobe, and occipital lobe; further, the left brain deals with logic, math, and science while the right brain handles feelings, art, and philosophy.

When processing facts, only two areas of the brain are activated (Broca's and Wernicke's) whereas a story will engage greater areas of the brain including the motor cortex, sensory cortex and frontal cortex.
Recently, Bogdanov, Smith, and Frey (2012) used imaging studies to demonstrate that hand amputation induces substantial reorganization of the primary sensory cortex (S1), and the effects of deafferentation increase with time.
The secondary cortical area (or associated area) is tasked with interpreting the signals delivered to the primary sensory cortex or, in the case of motor cortex, selecting the voluntary movements to execute.
In Pittsburgh, Schwartz's team is about to test another approach -- a brain-controlled robotic hand for the paralyzed that would ''feel'' through electrodes implanted in a brain region known as the sensory cortex.
