ASMR is usually precipitated by stimuli referred to as "triggers". [9] ASMR triggers, which are most commonly auditory and visual, may be encountered through the interpersonal interactions of daily life. Additionally, ASMR is often triggered by exposure to specific audio and video.
Stimming has been interpreted as a protective response to overstimulation, in which people calm themselves by blocking less predictable environmental stimuli, to which they have a heightened sensitivity. [2] [4] A further explanation views stimming as a way to relieve anxiety and other negative or heightened emotions. [5]
Subliminal stimuli (/ s ʌ b ˈ l ɪ m ɪ n əl /; sub-literally "below" or "less than") [1] are any sensory stimuli below an individual's threshold for conscious perception, in contrast to supraliminal stimuli (above threshold). [2] Visual stimuli may be quickly flashed before an individual can process them, or flashed and then masked to ...
Chemical stimuli, such as odorants, are received by cellular receptors that are often coupled to ion channels responsible for chemotransduction. Such is the case in olfactory cells . [ 12 ] Depolarization in these cells result from opening of non-selective cation channels upon binding of the odorant to the specific receptor.
Within such a framework several kinds of stimuli have been distinguished. Sequential illustration of Pavlov's dog experiment In the theory of classical conditioning , unconditioned stimulus (US) is a stimulus that unconditionally triggers an unconditioned response (UR), while conditioned stimulus (CS) is an originally irrelevant stimulus that ...
Hyperekplexia (/ ˌ h aɪ. p ər. ɛ k ˈ p l ɛ k. s i. ə /; "exaggerated surprise") is a neurological disorder characterized by a pronounced startle response to tactile or acoustic stimuli and an ensuing period of hypertonia. The hypertonia may be predominantly truncal, attenuated during sleep, or less prominent after one year of age.

Brainwave entrainment is a colloquialism for 'neural entrainment', [25] which is a term used to denote the way in which the aggregate frequency of oscillations produced by the synchronous electrical activity in ensembles of cortical neurons can adjust to synchronize with the periodic vibration of external stimuli, such as a sustained acoustic ...
