SOC 32 Lecture Notes - Lecture 13: Photon, Sine Wave, Sound Intensity
Document Summary
All cells have a specialised structure - not all sensors are located inside of the body (sensory receptors can be used in order to be able to understand your own body) Sensory receptors are specialised so that they can optimally transform physical information into electrical potentials - receptor potentials. More surface area - increase the capacitance, they can move as well, helps in the deactivation of receptors (enhance the temporal course of perception) Ap there are the decoding of the sensory perception will first start with the encoding of stimulus at the level of periphery based on the variations in the physical stimuli. A special type of receptors (nociceptors) bind multiple stimuli and are activated by them. Pain receptors are just individual fibers, without many channels on them; in order to be able to have enough depolarisation to activate the membrane potentials, you need to apply a lot of force.
