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 ...

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 ...

Political views are often so staunchly held that one wonders whether they aren’t hardwired in a person’s genes. Indeed, in the past, studies of twins have suggested that DNA may play a role in ...

Explore how political attitudes and physiological responses intertwine, revealing insights into our biological reactions to threats. When we're suddenly confronted with a shocking image, our skin ...

These experiments examined the impact of extensive depletions of forebrain 5-hydroxytryptamine (5-HT; serotonin) levels on prepulse inhibition (PPI) of the acoustic startle reflex in rats. In ...

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 ...

While swaddling can help soothe newborns by mimicking the womb, it's crucial to do it correctly. Improper swaddling increases ...

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 ...

New research published in The Journal of Physiology suggests that a cause of whiplash injuries could be startle reflexes elicited by unexpected loud sounds. New research published in The Journal of ...
