“…Both factors might have influenced the latencies and amplitudes of ERP components. The impact of chronic anti-convulsive medication on ERPs has not been systematically investigated as yet, but impairment of reaction velocity is a core side effect of this kind of medication and a down slowing of ERP components has been described for medicated epilepsy patients (Drake et al, 1986;Triantafyllou et al, 1992;Verleger et al, 1997). However, the peak latency of the MMN observed in the current sample does not differ notably from MMN latencies reported for healthy subjects when the same kind of deviance was applied (Todd et al, 2000).…”

Hippocampal event-related potentials to tone duration deviance in a passive oddball paradigm in humans

The mismatch negativity (MMN), a component of event-related potentials (ERPs), is assumed to reflect a pre-attentive auditory discrimination process. Although an involvement of hippocampal structures in deviance detection was shown in animal experiments, invasive recordings in humans have not been able to provide such an evidence so far. In the current study, ERPs were recorded from intrahippocampal and scalp electrodes in 16 epilepsy patients. Stimulation consisted of trains of six tones, with one tone deviating in duration (100 vs. 50 ms). In the rhinal cortex, ERPs elicited by deviants were larger in amplitude than those of standards (around 200 ms). The rhinal activation was succeeded by a long-lasting hippocampal ERP component (around 350 ms). However, in contrast to the rhinal activation, hippocampal activation was also elicited by the 1 st stimuli of the train and might, therefore, be related more to salience detection than to deviance detection. The current study provides evidence that the MMN is part of a multistage comparison process and that the rhinal cortex is part of its underlying cortical network.

“…Conversely, concordant results came from the few studies of cortical long-latency auditory evoked potentials, which did not show significant differences between migraineurs and controls with regard to N1, P2 and N2 component latency or amplitude [22,61].…”

“…There were reported normal interictal latencies [22, 39, 57-59], increased latencies (especially for wave V) [60,61], in particular during the attack [57,58], and inter-aural asymmetries [60], especially in migraine with aura [62]. A negative correlation was also described between discomfort caused by low-intensity stimulations (55 dB) and wave IV-V amplitude [22].…”

Migraine is an ictal disorder characterised by a particular vulnerability of patients to sensory overload, both during and outside of the attack. Central nervous system dysfunctions are supposed to play a pivotal role in migraine. Electroneurophysiological methods, which aim to investigate sensory processing, seem thus particularly appropriate to study the pathophysiology of migraine. We have thus reviewed evoked potential studies performed in migraine patients. Although results are in part contradictory, these studies nonetheless demonstrate an interictal dysfunction of sensory cortices, and possibly of subcortical structures, in migraine with and without aura. The predominant abnormality is a deficient habituation of evoked responses to repeated stimuli, probably due to cortical, and possibly widespread neural, "dysexcitability".

“…The resistance of the electrodes was kept below 5 kohm. The analog filter band pass was 1-100 Hz (Drake et al, 1989). For each stimulus, an epoch of 500-ms duration including a 100-ms pre-stimulus period was extracted from the continuous EEG.…”

Problem statement:Cognitive impairment is one important problem in post-menopausal women. Although hormone therapy can improve this condition, it also produces adverse effect. Recent findings showed that this condition could be mitigated by the herb. Ginger or Zingiber officinale Roscoe, a plant in a family of Zingiberaceae, was previously demonstrated the neuroprotection and cognitive enhancing effects. Therefore, this study was set up to determine whether ginger rhizome extract could improve attention and working memory of the postmenopausal women. Approach: Sixty healthy post-menopausal women were randomly assigned to receive either placebo or standardized plant extract at doses of 400 and 800 mg once daily for 3 months. After the assessment of biographic information, they were evaluated the working memory and cognitive function using computerized battery test and the auditory oddball paradigm of event related potential before and after 3-month of intervention. Results: The ginger treated group decreased N100 and P300 latencies but increased N100 and P300 amplitudes in accompany with the enhanced working memory including the power of attention, continuity of attention, speed and quality of memory. Conclusion: Our results suggested that ginger is the potential cognitive enhancer for post-menopausal women. However, further researches are still required.
