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.
