Neural Habituation to Painful Stimuli Is Modulated by Dopamine: Evidence from a Pharmacological fMRI Study
In constantly changing environments, it is crucial to adaptively respond to threatening events. In particular, painful stimuli are not only processed in terms of their absolute intensity, but also with respect to their context. While contextual pain processing can simply entail the repeated processing of information (i.e., habituation), it can, in a more complex form, be expressed through predi...
متن کاملHabituation to complex emotional stimuli.
On each of three sessions, 5s viewed 20 presentations of an isolated accident (experimental group) or a benign (control group) motion picture scene. At the end of each session, 5s also saw the complete movie from which these scenes were taken. Skin conductance, self-reported distress, and, to a lesser extent, heart rate showed considerable carry-over of habituation from the accident scene viewe...
متن کاملPersonality, Anxiety, and Individual Variation in Psychophysiological Habituation and Sensitization to Painful Stimuli
Pain perception involves a complex, dynamic process. Research over the past several decades has indicated numerous factors that influence the modulation of pain perception in humans. Research also suggests that pain perception presents an intricate balance between a warning sign to protect the biological integrity of an organism and an adaptive process not to overtax the system. One such exampl...
متن کاملComparative sensitivity of a simulated driving task to self-report, physiological, and other performance measures during prolonged wakefulness.
OBJECTIVES The objectives of this study were to compare (1) the sensitivity of simulated driving to self-report measures, nocturnal sleep latency tests (SLTs), and an auditory vigilance task and (2) urban and motorway driving. METHODS Healthy males 18 to 35 years maintained wakefulness for one night and were tested at 2400, 0230, 0500 and 0730 h. In Study 1 (n=11), the SLTs were followed by a...
متن کاملOlfactory bulb habituation to odor stimuli.
Habituation is a simple form of memory, yet its neurobiological mechanisms are only beginning to be understood in mammals. In the olfactory system, the neural correlates of habituation at a fast experimental timescale involving very short intertrial intervals (tens of seconds) have been shown to depend on synaptic adaptation in olfactory cortex. In contrast, behavioral habituation to odorants o...
