|
Detailed explanation-1: -A stimulus is a change in the environment (either external or internal) that is detected by a receptor. Receptors transform environmental stimuli into electrical nerve impulses. These impulses are then transmitted via neurons to the central nervous system where decision-making occurs.
Detailed explanation-2: -Environmental stimuli were defined as ambient, architectural or interior design features that are intended purely to provide a stimulus and that influence patients through mediation by psychological processes.
Detailed explanation-3: -Stimuli are always converted into electrical signals via transduction. This electrical signal, or receptor potential, takes a specific pathway through the nervous system to initiate a systematic response.
Detailed explanation-4: -External stimuli are changes to conditions outside of the body, or in general, information from outside the body that our senses detect.
Detailed explanation-5: -Different types of stimuli from varying sources are received and changed into the electrochemical signals of the nervous system. This process is called sensory transduction. This occurs when a stimulus is detected by a receptor which generates a graded potential in a sensory neuron.
