PSYB51H3 Lecture Notes - Lecture 2: Photopic Vision, Ciliary Muscle, Vitreous Body
Document Summary
Psyb51 lecture 2: the first steps in vision. Adaptation (retina to dark and light) is not to be confused with accommodation (anatomy of the eye) Receptive fields something that a neuron in a brain has if it is responsive to some sensory stimulus: action potentials, for example. Filters sepa(cid:396)ate stuff f(cid:396)o(cid:373) the (cid:271)(cid:396)ai(cid:374) that (cid:455)ou do(cid:374)"t (cid:449)a(cid:374)t. Whether the face is currently visible or not) Contrast how the retina contrasts to differentiate information. Got to consider both of these natures and determine which is more relevant to your research. Light can be absorbed, diffracted, reflected, transmitted, or refracted. Example: solar panelled car transform solar energy into electrical energy for the car to run on. Red: other wavelengths filter out the light. Reflected: energy that is redirected when it strikes a surface: there are several surfaces on the eye. Refracted: energy that is altered as it passes into another medium: example: light entering water from the air.
