Why do adults have startle reflex?
Usually the onset of the startle response is a startle reflex reaction. The startle reflex is a brainstem reflectory reaction (reflex) that serves to protect vulnerable parts, such as the back of the neck (whole-body startle) and the eyes (eyeblink) and facilitates escape from sudden stimuli.
Do psychopaths startle?
Research indicates that psychopaths don’t experience fear like the rest of us. For example, how do you react if you’re suddenly startled by a loud noise? Most individuals will jump or immediately develop sweaty palms. However, experiments show that psychopaths barely startle–and their hands stay dry.
What causes exaggerated startle reflex in adults?
The exaggerated startle reflex in HPX is probably caused by brainstem pathology. This is supported by the concentration of glycine receptors in the brainstem and spinal cord (Rousseau et al., 2008). In addition, symptomatic excessive startling is usually caused by brainstem damage (Bakker et al., 2006).
Does Ms make you startle easily?
One of our contributors, Matt, wrote an article about how his “startle reflex” is extremely sensitive, and it actually has a detrimental effect on his quality of life.

The startling easily is a symptom, which is dynamic and can change from day to day, or from moment to moment.
What is the role of the BNST in the startle reflex?
The role of the BNST in the acoustic startle reflex may be attributed to specific areas within the nucleus responsible for stress and anxiety responses. Activation of the BNST by certain hormones is thought to promote a startle response The auditory pathway for this response was largely elucidated in rats in the 1980s.
