Document Summary
Sensation (general) - the detection of external stimuli and the transmission of this information to the brain. Distal stimulus - actual object or event located in the external world. It"s the stimulus that will provide information for the proximal stimulus. Proximal stimulus - registers information received via sensory neurons from the distal stimulus. Example of both stimulus at work - an example would be a person looking at a shoe on the floor. The image recorded onto the person"s retina (sensory receptor) is proximal stimulus. Recognizing it"s a tree/recording that image = proximal stimulus. Sensory receptors - cells specialized in detecting certain types of proximal stimulus. Transduction - the process by which sensory stimuli are converted to signals the brain can interpret (i. e. when a hand touches a hot skillet, the neurons in the hand and in the brain will signal pain.
