Across
- 2. This layer of the retina is the layer closer to the choroid that contains the photoreceptors
- 3. These photoreceptors are responsible for vision in bright light and provide details about color and acuity
- 6. These cells receive signals from bipolar and other cells like themselves as well as send signals back to the RGCs
- 7. The "what" pathway that passes from V1 to V2 to V4 and then to the inferotemporal cortex
- 12. This layer receives signals from the parasol RGCs and comes from a Latin word meaning great or layers 1-2 of the LGN
- 13. The "where and how" pathway that passes from V1 to V2 to Mt and then to the parietal cortex
- 14. This layer of the retina is between the synaptic layers and is is where the bipolar, horizontal, and amacrine cells are
- 15. This layer is attached to the choroid and contains the "business ends" of the photoreceptors where transduction occurs
- 17. These are the rods and cones that transduce light into neural signals and they are embedded into the pigment epithelium
- 18. The optic ---- is the location where the optic nerves from the two eyes split in half, with half the axons from each eye crossing over to the other hemisphere of the brain.
- 22. These cells receive signals from the photoreceptors and send signals to the amacrine and RGCs
- 23. This is the main interior portion of the eye
- 24. The inner membrane of the eye that contains the photoreceptors
- 27. This layer receives signals from the midget RGC and comes from a Latin word meaning small or layers 3-6 of the LGN
- 29. This structure is where a small section (about 10%) of the axons of the optic tract travel near the top of the brain stem whose principal function is to help control eye movements
- 31. The RGCs that send signals to the parvocellular layers of the LGN
Down
- 1. These cells receive signals from the bipolar and amacrine cells and then send action potentials to the brain via the optic nerve
- 2. This layer of the retina contains the synapses among photoreceptors, bipolar, and horizontal cells
- 4. The cortex that is involved in the dorsal pathway of the visual system and is the are that perceives space and motion and coordinates visual-motor interactions
- 5. From the Greek for grains of sand, these layers receive signals from the bistratified RGCs
- 7. The 2nd layer of the visual cortex part of the pathway from RGCs to the higher visual areas
- 8. The RGCs that send signals to the koniocellular layers of the LGN
- 9. The middle membrane of the eye that lines the interior of the sclera and has most of the blood vessels that supply the inside of the eye with oxygen and nutrients
- 10. The cortex that is involved in the ventral pathway of the visual system and is the are of object recognition
- 11. The RGCs that send signals to the magnocellular layer of the LGN
- 16. This layer of the retina is between the ganglion cell layer and the inner nuclear layer and is where the synapses among bipolar, amacrine, and RGCs occur
- 19. These cells receive and send signals to photoreceptors and other cells like themselves
- 20. Part of the dorsal pathway that processes motion that is in the middle temporal lobe
- 21. The optic ---- is the continuation of the optic nerve past the optic chiasm and the right one consists of axons from the RGCs in the right half of each retina, same for the left
- 23. Part of ventral pathway where shapes/forms are processed that is in the occipital lobe
- 25. This optic ---- is formed by the bundling together of the axons of the RGCs and it exits the eye through the optic disk.
- 26. This cell layer contains the RGS and is the nuclear layer closest to the vitreous chamber
- 28. This is the primary visual cortex in the occipital lobe where signals flow from the LGN
- 30. These photoreceptors are responsible for vision in dim light
