    Study Notes

    • The text discusses the principle of the "labeled line" in the transmission of sensory information to the brain

    • Sensory receptors have specific responses to different types of stimuli, and each type of receptor produces a unique electrical signal

    • Receptor potentials are changes in the electrical potential of the receptor membrane in response to stimuli

    • Mechanisms of receptor potentials include mechanical deformation, chemical application, temperature change, and electromagnetic radiation

    • Maximum receptor potential amplitude is around 100 millivolts and only occurs at high intensity stimuli

    • Receptor potentials can elicit action potentials in the nerve fiber attached to the receptor

    • Receptors adapt to constant stimuli by reducing their response rate over time

    • There are different types of nerve fibers with varying diameters and conduction velocities, which correspond to different sensory modalities

    • Some receptors, like the Pacinian corpuscle, have unique structures that allow for specific responses to stimuli

    • Spatial and temporal summation allow for the transmission of signals of varying intensity in nerve tracts.
