PSYC 110 Lecture Notes - Lecture 19: Taste Receptor, Proprioception, Miraculin
Document Summary
General sensory process: physical stimulus-> physiological response sensory experience, physical stimulus, matter or energy influencing the body, physiological response, chemical/ electrical activity within the body, sensory experience, subjective sensation (psychological experience) How many senses do we have: classic 5, touch, taste, smell, sight, sound, others, proprioception, vestibular/ gravity, time, spacial. Wet = cold and pressure: touch sensors, if you lightly stroke touch sensors you get the feeling of a tickle or an. Itch, if you lightly stroke a touch sensor sometimes you stimulate pain receptors too that"s (cid:449)hy you get an itch: searing hot is adjacent cold vs. warm. Sensor mapping: fingertip, front/back hand, forearm, back, cheek. Note: interneurons only connect to other neurons, but sensory neurons connect to the outside world. Survival functions: sweet, umami (savoriness/protein, fat, sour, salty, bitter. Reality is just a construction of the mind, if you change the physiological response, you change the subjective experience: class demonstration.
