Document Summary
Lecture 2. 1 - measurement of neural structure and function. Neuroscientists usually seek reductionist, causal, mechanistic explanations of how system components interact to produce system behaviour. Motor/sensory motor: segmental reflexes, primitive reflexes, strength, symmetry, palsy, cranial nerves, balance, posture, gait. Part 1: reduction to fundamental components and mechanisms. Structured observations and critical experiments can be directed at the question of. Spatial resolution: how small a thing can i see if two things are close together can i differentiate them. Most tissue is transparent -> need to stain it to differentiate. If no stain, can look at the refractive properties of tissue -> can look at interference and see what structures are causing this interference. If the refracted light is collected -> will produce some sort of image. Electron microscopes are limited can"t look at much other than where heavy metal stains are found. Looked at one light source at a time (one pixel at a time)
