Stimulation is the encouragement of development or the cause of activity in general. For example, "The press provides stimulation of political discourse." An interesting or fun activity can be described as "stimulating", regardless of its physical effects on senses.
In this context, a distinction is made between the distal stimulus (the external, perceived object) and the proximal stimulus (the stimulation of sensory organs). [ 1 ] In perceptual psychology , a stimulus is an energy change (e.g., light or sound) which is registered by the senses (e.g., vision, hearing, taste, etc.) and constitutes the basis ...
Sexual stimulation is a broad term, usually understood to mean physical touching of the genitals or other body parts. The term can, however, include stimuli affecting the mind (sexual fantasy), [1] or senses other than touch sight, smell, or hearing). Sufficient physical stimulation of the genitals usually results in an orgasm.
Brief stimulation produces adaptation which occurs and recovers while more prolonged stimulation can produce slower and more lasting forms of adaptation. [2] Also, repeated sensory stimulation appears to temporarily decrease the gain of thalamocortical synaptic transmission. Adaptation of cortical responses was stronger and recovered more ...
Examples of mechanoreceptors include baroreceptors which detect changes in blood pressure, Merkel's discs which can detect sustained touch and pressure, and hair cells which detect sound stimuli. Homeostatic imbalances that can serve as internal stimuli include nutrient and ion levels in the blood, oxygen levels, and water levels.
Self-stimulatory behavior, also known as "stimming" [1] and self-stimulation, [2] is the repetition of physical movements, sounds, words, moving objects, or other behaviors. Stimming is a type of restricted and repetitive behavior (RRB). [ 3 ]
The following are examples of stimuli to which receptors may: Light – When the adequate stimulus of a sensory receptor is light, the sensory receptors contain pigment molecules whose shape is transformed by light, and the changes in these molecules activate ion channels which initiate sensory transduction .
For example, the temperature modality is registered after heat or cold stimulate a receptor. Some sensory modalities include: light, sound, temperature, taste, pressure, and smell. The type and location of the sensory receptor activated by the stimulus plays the primary role in coding the sensation. All sensory modalities work together to ...
