Fear, Startle, and Fear-Potentiated Startle : Probing Emotion in the Human Brain
, 2003 The present thesis explored the neurobiological basis of three aspects of defense behaviors in humans. Positron emission tomography methodology was used, and changes in regional cerebral blood flow (rCBF) were measured as an index of neural activity ...

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021 Abstract Background Posttraumatic stress disorder (PTSD) is associated with autonomic dysfunction as indicated by deficits in the sympathetic and parasympathetic nervous systems. These abnormalities are expressed as elevated heart rate and reduced heart rate variability (HRV), respectively.

Second-Order Olfactory-Mediated Fear-Potentiated Startle [PDF]
Learning & Memory, 2002 Recently, we reported that discrete (4-sec) olfactory cues paired with footshock serve as effective conditioned stimuli (CSs) for potentiating the acoustic startle response in rats using the fear-potentiated startle paradigm. Because odors are such salient cues for the rat, and because of the robust olfactory conditioning observed previously, the ...

Developmental investigation of fear-potentiated startle across puberty [PDF]
Biological Psychology, 2014 The goal of this study was to examine the association between affective development, puberty, and gender using the startle reflex as a marker of defensive mechanisms. Thirty-one male and thirty-five female adolescents aged ten to thirteen participated in a prospective study with up to five assessments.

Loop diuretics have anxiolytic effects in rat models of conditioned anxiety. [PDF]
PLoS ONE, 2012 A number of antiepileptic medications that modulate GABA(A) mediated synaptic transmission are anxiolytic. The loop diuretics furosemide (Lasix) and bumetanide (Bumex) are thought to have antiepileptic properties.
