Cognitive dysfunction in NIDDM: P3 event related evoked potential study.
P3 component of the endogenous cerebral evoked response is a sophisticated, objective and quantitative approach to assess higher functions of the brain. This test was employed using auditory 'odd ball' paradigm to assess cognitive functions in thirty non insulin dependent diabetic patients (NIDDM) aged 43.6 +/- 9 yrs with poor blood glucose control. (HbAlc. 9.9 +/- 1.0%). The peak latencies of ...
متن کاملP3 event related evoked potentials in pregnancy.
Cognitive function using P3 auditory event related evoked response was examined in 18 pregnant women of age group 18-25 years (Mean 21.78 +/- 2.1). P3 was obtained from scalp electrodes at CZ, PZ referenced to ear lobules during a task in which the subjects concentrated and pressed the button on hearing high pitched rare clicks in a train of low-pitched frequent and high pitched rare clicks. La...
متن کاملThe P3 auditory event-related brain potential indexes major personality traits.
BACKGROUND The amplitude of the auditory P3 event-related potential is reduced in patients with axes I and II disorders. Data regarding P3 amplitude and normal personality traits in healthy individuals have been inconsistent, however, although more extreme variants of dimensional traits such as neuroticism and extraversion are associated with psychiatric morbidity. METHODS Male subjects (n = ...
متن کاملEvent-related potentials--the P3 wave.
Event-Related Potentials (ERPs) are a basic, non-invasive method of neurophysiological investigation. They can be used to assess aspects of human cognitive information processing. They also can be used in experiments on higher mammals. The most important and the most studied component of the ERP record is the P3 wave. It consists of two parts, P3a and P3b. There is no doubt that, besides the us...
متن کاملSpecificity of P3 event-related potential reactivity to alcohol cues in individuals low in alcohol sensitivity.
Recent research using event-related potentials (ERPs) has shown that individuals low in alcohol sensitivity show increased P3 reactivity to alcohol cues (Bartholow, Henry, & Lust, 2007). The current research sought to test the specificity of this effect by including other arousing cues in addition to alcohol, and by controlling for individual differences in trait impulsivity. Forty-seven partic...
