8.611 light years away at the speed of light. You just answered your own question. A light year is a measurement of distance not time. If something is 8.611 light years away it means it will take light 8.611 years to reach Sirius. So the answer is 8.611.

Somatic motor cortex is in Frontal lobe , somatic sensory cortex is in Parietal lobe, auditory cortex is in temporal lobe and visual cortex is in Occipital lobe. Was this helpful?

Primary somatosensory cortex (SI; areas 3,1,2) is located in the post central gyrus. This receives somatotopic input from the VPL and VPM of the thalamus. Histologically, this area would consist of granular cortex.ssociation and Commissural Fibers. Finally, regions of the cerebral cortex are tied together by bundles of white matter fibers. There are association bundles that connect one part of the cortex to another. These association fibers typically arise from layer III and terminate in layers I and II.
