increase- sensory receptors require increasing stimuli to activate
does the sensory threshold level in an elder increase or decrease?
Sensory receptors are specialized cells in our body that are responsible for detecting different types of stimuli such as light, sound, touch, taste, and smell. These receptors respond to specific types of stimuli and send signals to the brain, which processes and interprets the information received.
It is true that sensory receptors require increasing stimuli to activate over time, a phenomenon known as sensory adaptation. When sensory receptors are repeatedly exposed to the same stimulus, they become less responsive to it over time, and progressively stronger stimuli are required to elicit the same response.
This adaptation of sensory receptors is a natural and useful process that allows our bodies to adjust to constant stimuli and focus on new or changing stimuli. For example, if you spend a lot of time in a noisy environment, your hearing will adapt to this constant level of noise, and you will be able to perceive lower levels of sound.
However, this adaptation can also have negative effects, such as desensitization to pain or loss of sensitivity to certain senses. This is why it is important to vary our sensory experiences and expose ourselves to different types of stimuli, to maintain our sensitivity and responsiveness to different sensations.
