If several neurons of the visual cortex all respond best when the retina is exposed to horizontal lines of light, then those neurons are probably in the same ________.
Supreeta N.
11. Retinotopic Mapping a. is explained by all the above. b. is the way things close together in the visual scene get imaged on the retina and get sent to the LGN and area V1. c. is the reason why the retinal gannglion cells send so much more information to the LGN than to the visual cortex. d. takes place in the retina, but some of the information gets shuffled around before it reaches the visual cortex. 12. Cells in the primary visual cortex are activated by a. spots of light on the On-center Off-surround receptive fields. b. curved lines and edges only. c. elongated lines. d. all of the above. 13. All except the following is true about Orientation Selectivity in the cortex. a. How well a cell responds to non-prferred stimuli tells us about its tuning. b. As long as the stimulus line is vertical or tilted and well-tuned, a cortical cell will respond. c. A cortical cell that is oriented to a vertical line will likely also respond to a line that is tilted 10 degrees, or just slightly off vertical, but less strongly. d. For each cell, the line must be of a particular orientation (vertical, tilted, horizontal) - including when tilted to a specific degree to elicit the greatest response. 14. The largest of the visual areas in the occipital lobe, the primary visual cortex, is also called a. LGN b. Superior Colliculus c. The ExtraStriate Area d. V17 15. Hypercomplex Cells in the Primary Visual cortex a. respond more actively - as the length of a bar increases and covers more of the length of its receptive field - than a complex cell respoonds if the length of a bar increases exactly the same amount, covering same length of its receptive field. b. often known as end-stopped cells, result from a number of Complex Cells combining. c. Are often known as end-stopped cells because once the length of the bar reaches past the ends of the receptive field, response becomes very weak. d. respond most actively to the longest bars (even if the bar goes past the end boundary of the receptive field).and optimal orientation.
