Unexpected Stimuli in Humans

چکیده
KNIGHT, R. T. Aging decreases auditory event-related potentials to unexpected stimuli in humans. NEUROBIOL AGING 8(2) 109--I 13, 1987.--A P300 event-related potential (P3a) was recorded to unexpected, deviant auditory stimuli requiring no behavioral response. This brain potential underwent systematic latency prolongation and amplitude decrease with advancing age. The age-related changes paralleled those of the P300 (P3b) recorded in target detection tasks. These results provide physiological evidence of a decremented CNS response to unexpected stimuli with aging.

Neonatal Hyperekplexia: A Case Report
Hyperekplexia is a rare non-epileptic disorder characterized by an exaggerated and persistent startle reaction to the unexpected tactile and acoustic stimuli. The disorder is occasionally associated with generalized muscular rigidity and has the clinical hallmark of positive nose tapping test.The disease is inherited in an autosomal dominant fashion. Recessively inherited and sporadic forms of...
متن کاملStriatal and midbrain connectivity with the hippocampus selectively boosts memory for contextual novelty
The role of contextual expectation in processing familiar and novel stimuli was investigated in a series of experiments combining eye tracking, functional magnetic resonance imaging, and behavioral methods. An experimental paradigm emphasizing either familiarity or novelty detection at retrieval was used. The detection of unexpected familiar and novel stimuli, which were characterized by lower ...
متن کاملEarly indices of deviance detection in humans and animal models.
Detecting unexpected stimuli in the environment is a critical function of the auditory system. Responses to unexpected "deviant" sounds are enhanced compared to responses to expected stimuli. At the human scalp, deviance detection is reflected in the mismatch negativity (MMN) and in an enhancement of the middle-latency response (MLR). Single neurons often respond more strongly to a stimulus whe...
متن کاملRapid prefrontal-hippocampal habituation to novel events.
Unexpected novel events generate an orienting response that plays an important role in some forms of learning and memory. The orienting response involuntarily captures attention and rapidly habituates as events become familiarized. Although evidence from patients with focal lesions and scalp and intracranial event-related brain potential recordings supports the involvement of a distributed neur...
متن کاملSimulation of individual spontaneous reactive behavior
The context of this work is the search for realism and believability of Virtual Humans. Our contribution to achieve this goal is to enable Virtual Humans (VH) to react to spontaneous events in virtual environments (VE). In order to reflect the individuality of each VH, these reactions have to be expressive and unique. In this paper we present firstly a model of reaction based on personality tra...
