Document Summary
We have certain frequencies withiin speech sounds that have more energy they are formants. Formants helps us tell diff sounds apart, it"s the timbre peaks, they are a bar code of the sound relationship between them and distance between them will tell us about diff sounds. Receptors can be classified according to 3 dimension: type of stimulation (ex mechanostimulation), size of receptive field, and rate of adaptation (how quickly do the receptors stop firing adapts it will stop firing) Mesmer and merkel have small receptive fields (german i) Receptive fields are so large, doesn"t have precise adaptation not as sensitive. Kinesthetic: not in the skin, they are in muscles tendons Muscle spindles, when you try to trick them they involve vibrators, brain thinks biceps are strectching when vibrating and holding nose, brain interprets as if your nose is growing. Tendon proprioreceptors and spindles and also in the joints. 2 sets of thermoreceptos, code cold info and warm info.
