Across 1. A LSD flashback might tigger this mixing of the senses 7. Human LGN cells are different than feline LGN cells because they are... 8. Poor fixation expected to reduce acuity (or because of reduced acuity) in ocular albinism 10. Type of correspondence in non-suppressiing, non-diplopic strabismics 12. These LGN cells are blue-yellow opponent in all six layers 14. Brain structure that looks like a salmon steak when you slice it 16. These LGN cells see lower spatial frequency better 17. Brain structure that controls circadian rhythms, mood and behavior

Down 1. The equivalent of the optic tectum in frogs, controls reflex foveation 2. Midbrain structure that controls the vestibular-ocular reflex 3. Four-fifths of inputs to the LGN are this type 4. Describes ennervation to layers 1, 4, and 6 of the LGN 5. These LGN cells have lower sensitivity to flicker 6. Describes ennervation to layers 2, 3, and 5 of the LGN 9. This part of the thalamus is a valve for hearing (audition) 11. In humans, midbrain structure used to control optokinetic eye movements 13. The common result of long-term suppression of an amblyopic eye 15. Brain structure that integrates spatial coding and feature binding

The look has changed! Some of the puzzles that people list for the public get indexed by the search engines (like Google). Some people find those puzzles and cannot figure out how to make a puzzle of their own. So this page now has the navigation sidebar.

Use the "Printable HTML" button to get a clean page, in either HTML or PDF, that you can use your browser's print button to print. This page won't have buttons or ads, just your puzzle. The PDF format allows the web site to know how large a printer page is, and the fonts are scaled to fill the page. The PDF takes awhile to generate. Don't panic!
