Fully optimized discrimination of physiological responses to auditory stimuli

Fully optimized discrimination of physiological responses to auditory stimuli.

The use of multivariate measurements to characterize brain activity (electrical, magnetic, optical) is widespread. The most common approaches to reduce the complexity of such observations include principal and independent component analyses (PCA and ICA), which are not well suited for discrimination tasks. We addressed two questions: first, how do the neurophysiological responses to elongated p...

Emotional responses to auditory stimuli

The responses of horses to predator stimuli

It is not known whether the instincts of wild horses have remained strong during their centuries of domestication. Knowledge of this matter would give riders the opportunity to know more about the behavior of horses and consequently about safety for both horses and riders. In this current research, we studied the behavior of fifteen Caspian miniature horses of different ages and sexes using sti...

Neuromagnetic steady-state responses to auditory stimuli.

Steady-state magnetic responses to clicks presented at rates between 10 and 70 Hz have been recorded in healthy humans. The responses were highest in amplitude around 40 Hz. This amplitude enhancement is satisfactorily explained by summation of responses evoked by single clicks. The field maps suggest activation of the auditory cortex at all stimulus frequencies. Similar responses were obtained...

Differences in Physiological Responses to Exposure of Disturbing Auditory Versus Audiovisual Stimuli

Fear plays a significant role in the lives of many people, from crippling fear that prevents people from performing everyday activities, to that which is intentionally experienced from video game or horror movies. The physiological responses to fear-inducing stimuli may vary between individuals, but some common reactions include increased heart rate, respiration rate and muscle tension, collect...
