Unformatted text preview: Confocal imaging of dendritic spine density. 2. Single unit recording. 3. VEP recording. 4. Intrinsic optical imaging of cortical maps. 3) (3 Point) How was cycloheximid delivered to the visual cortex? Why such method is used? How do authors confirm that protein synthesis is blocked? How much reduction in protein synthesis is achieved in V1 block? • Use osmotic minpumps to infuse cyclohexmid directly into the brain. (1pt) • This method is used to establish a reliable, constant inhibition on protein synthesis. (0.5 pt) • Incorporation of tritium-labeled amino acid leucine into nascent proteins, and measure it by autoradiography (or silver grain counts). (1 pt) • ~50% (45 ± 12%) protein synthesis block is achieved at the midpoint of V1. (0.5pt) ....
