Psychologists Link Emotion to Vividness of Perception and Creation of Vivid Memories - Psychologists overlaid images with visual noise to measure perception. After accounting for other features of images that contribute to perceptual vividness, such as contrast, color, and scene complexity, they found emotionally arousing images to be perceived more vividly, and thus contributing partly to more vivid memories of certain images later.

Module 4. "Types of anopsias (visual field defects) and corresponding anatomical insults." Note that anything behind the chiasm gives a homonymous defect (anything along the optic tract, LGN, optic radiations, or visual cortex).

Scraperboard drawing by Bill Sanderson 1997 via the Wellcome Library London.  Practicing paying attention can boost performance on a new task and change the way the brain processes information a new study says. This might explain why learning a new skill can start out feeling grueling but eventually feels more natural  although right now the studys findings are limited to a simple pattern-recognition game.  Theres a long-standing debate about how exactly paying attention helps us learn. One…

CRANIAL NERVES ------- Optic nerve (CN 2), sensory only. Receptors in the retina (rods & cones) synapse with bipolar cells, which synapse with ganglion cells. Ganglion cells form optic nerve. Crossover at optic chiasm. Tags: skull, brain, eye, anatomy, dissection, human, body, health, nature, science, biology
