Vertical stripes presented in front of animals injected with radioactive 2-deoxy-glucose led to columns of radioactivity in the primary visual cortex that were the same width as the non- radioactive spaces between them. What does this tell us about the way the visual cortex is organized? 2. Know the details of the optic tract projections through the optic chiasm to the thalamus. 3. How are rods distributed in the retina? 4. If a persons optic chiasm were cut down the midline, in what regions of the retina would the individual be blind? 5. Where is the receptive field of a visual neuron found? 6. Which type of visual system cells display a direction preference? 7. What is the opponent processing theory of color perception? 8. When a spot of light is shone simultaneously in the surround and center of the receptive field of an on-center cell, what does the ganglion cell do in terms of firing rate? 9. When light (photons) strikes the photoreceptor contained in rhodopsin what does the membrane potential of the rod do? 10. What does transduction mean? 11. Cortical cells that have receptive fields that can be divided into "on" areas and "off" areas that are separated by straight unmoving lines are referred to as what kind of visual cell? 12. High-acuity vision is mediated by what system of vision? 13. Which visual system exhibits a high degree of neuronal convergence compared to a low degree of neural convergence, and what does that mean in terms of visual acuity? 14. Know the characteristics and differences between the photopic and scotopic system. 15. Know the sequence of cells in the retina from the pigment epithelium outward (towards the lens of the eye). 16. What is the organizational mapping principle of the retino-geniculate-striate system called? 17. Fined grained feature detection and contrast perception are mediated by which visual pathway system? 18. What is the principal photoreceptor (what light interacts with) called? 19. Single opponent cells code for what? 20. What is the white of the eye called? Neurotransmitter Systems (15 questions) 21. The central serotonin system is important for what? 22. Which neurotransmitter system has been associated with schizophrenia? 23. What are the three properties of neurotransmitter receptors that distinguish them from other cellular sites that bind a drug? 24. The safest to most dangerous routes of drug administration are what? 25. According to the lectures, what is considered the best way of classifying drugs? 26. In terms of efficacy, what do drug antagonists exhibit at neurotransmitter receptors? 27. What do you call a drug that facilitates the activity of a particular neurotransmitter system? 28. Drugs that block the re-uptake of a neurotransmitter from the synapse are classified as what? 29. Know the 5 criteria that H.H. Dale suggested that a chemical must meet before it can be considered a neurotransmitter. 30. What are the names of the two principal dopamine neuronal pathways in the central nervous system? 31. The central dopamine system is important for what? 32. Which neurotransmitter system has been associated with Alzheimer’s disease? 33. Which neurotransmitter system has been associated with Parkinson’s disease? 34. What are the two principle properties of action of all agonists called? 35. Which neurotransmitter systems have been associated with affective (depression) disorders?
