Document Summary
This lecture: how somatosensory cortex processes and reconstructs (decodes, need to reconstruct to turn the population of spikes into a representation of the object in the hand or the texture on a surface. Need to make judgement about the outside world why you need to reconstruct: can only do this in the brain not in the outside world. How these groups of neurons provide information about the outside world: deconstruct it into spikes, how the spikes are interpreted in the brain. Cerebral cortex: outside coating of the brain: grey matter that surrounds the brain, highly folded cortex. It is subdivided functional subdivision somatosensory processing pathway. Somatosensory cortex: have a strong representation of somatosensory signals (labelled functionally in that domain: location = behind the central sulcus, critical for conscious appreciation for somatosensory stimuli ; for you to report things about how they feel.
