The ASR is the change in behavior in reaction to either a surprise or prepared acoustic event. This change can be immediate or long lasting,
The brainstem, specifically the superior olivary complex, is responsible for processing auditory reflexes such as the startle reflex and sound localization.
The amygdala, which is part of the limbic system in the brain, is primarily responsible for the startle response. It is involved in processing emotions and is particularly important for fear-related behaviors.

The appropriate sequence is as follows: Present the auditory stimulus (unconditioned stimulus) Follow the auditory stimulus with a puff of air to the eye (unconditioned response) Pair the auditory stimulus with the puff of air multiple times Eventually, the auditory stimulus alone will elicit an eyeblink response (conditioned response)
UCS (Unconditioned Stimulus): Loud noise UCR (Unconditioned Response): Startle reaction CS (Conditioned Stimulus): Flashing light CR (Conditioned Response): Startle reaction
The red light reflex (startle response) is a withdrawal response in the abdominal muscles in which the body curves in on itself in response to distress.
heightened arousal
That feeling is known as the startle response or a startle reflex. It is a natural reaction where your body quickly responds to a sudden stimulus by contracting muscles and increasing alertness.
The tectospinal tract is involved in reflex movements of the head in response to visual and auditory stimuli. It originates in the superior colliculus of the midbrain and carries signals for reflexive head and neck movements in response to sensory input.
Because less neural processing is required and the nerve "circuitry" is much simpler for auditory input than for visual input.
