In the present study, we investigated whether mice lacking the arginine vasopressin (AVP) V1b receptor (V1bR) exhibit deficits of prepulse inhibition (PPI) of the startle reflex, reminiscent of the ...

To understand the expressive range of the human face, nothing beats watching a colleague scream his head off in slow motion. When my lab began to study protective reflexes in the early 2000s, the ...

The SR-LAB startle response system is the world's most popular startle reflex research tool for assessing fear-potentiated startle (FPS), pre-pulse inhibition (PPI), and startle habituation. SR-LAB ...

I’ve been reading a lot recently about the startle reflex as it applies to folks who suffer with panic disorder and agoraphobia. As you probably suspected, people diagnosed with this wretched curse ...

The startle response, often recorded as an eye-blink reflex, is a defensive measure believed to reflect emotional processing. Patients with alcohol use disorders (AUDs) show abnormal startle-reflex ...

We all jump at an unexpected noise or touch, but in some people, this startle response is exaggerated, and can cause falls and even death. Now, researchers in the United Kingdom have found new genes ...

University of Toronto researchers have discovered that the main purpose of the startle reflex -- the mechanism that makes people twitch at sudden loud noises -- is to protect the body against blows.

Traumatic Brain Injury (TBI) is a leading cause of death and disability in military and civilian populations. TBI can occur from a number of insults - such as blunt force, blast impact, or penetrating ...

The startle reflex is a rapid, involuntary response to sudden acoustic stimuli, and its study has provided valuable insights into the neural mechanisms underlying motor preparation. Research in this ...

Humans are born with only two primal fears: falling and loud noises, research reveals. The fear of falling emerges early, demonstrated by infants' hesitation at 'visual cliffs.' The 'startle reflex' ...
