What Cells Are In The Primary Visual Cortex? The three major groups of so-called feature detectors in visual cortex include simple cells, complex cells, and hypercomplex cells. Simple cells are the most specific, responding to lines of particular width, orientation, angle, and position within visual field. What are simple cells in the primary visual cortex?
What Did Hubel And Wiesel Demonstrate About How Visual Processing Works? Hubel and Wiesel demonstrated that some neurons were only responsive to information that came from a single eye, a phenomenon they referred to as “ocular dominance”. Intriguingly, neurons that are tuned to a particular eye cluster together in anatomical columns in the visual cortex
What Is The Source Of Most Of The Input To The Left LGN? Question 2: What is the source of most of the input to the left LGN? Answer: The left LGN receives retinal information about the right visual field. Left LGN neurons receive synaptic input from the retinal ganglion cells in the nasal half
