Cortical Auditory Evoked Potentials

Left handers and women show less anatomical brain asymmetry, larger corpus callosum and more bilateral representation of specific functions. Sensory and cognitive components of cortical auditory evoked potentials (AEF) have been shown to be asymmetric in right handed males and to be influenced by stimulus intensity. In this study the influence of sex, handedness and stimulus intensity upon AEP components is investigated under basal conditions of passive attention. 14 right handed males, 14 right handed females, 14 left handed males, and 14 left handed females were studied while lying awake and paying passive attention to auditory stimulation (series of 100 binaural clicks, duration 1 msec, rate 1/sec, at four intensities). Cz, C3 and C4 referenced to linked mastoids and right EOG were recorded. Analysis time was 400 msec, average evoked potentials were based on 100 clicks. Stimulus intensity and gender affect early sensory components (P1N1 and N1P2) at central leads, asymmetry is influenced only by handedness, right handers showing larger P1N1 amplitudes over the right hemisphere.

The Impact

Abstract To investigate the impact of several methodological variations in the assessment of augmenting/reducing, auditory evoked potentials to 1000 Hz tones with varying stimulus intensity (59, 71, 79, 88, 92, 96 dB (SPL)) were recorded at 19 EEG sites in 24 participants during two separate recording sessions. The internal consistency analysis revealed only weak correlations for linear regression slopes based on high intensity levels when compared to slopes based on low intensity levels. For base-to-peak and peak-to-peak ERP component measurements, acceptable internal consistency and temporal stability were confirmed for the N1/P2-based slope, and partly for the P2 slope, whereas P1, N1, and P1/N1 slopes were not reliable. After submitting auditory evoked potentials to a covariance-based principal component analysis (PCA), followed by unscaled varimax rotation, temporal stability of slope measures for the corresponding factor scores substantially increased. The findings suggest that at least five to six intensity-levels are required over a relatively broad range to yield a reliable measure of auditory evoked augmenting/reducing. If measured reliably, P2 slopes may reflect stimulus intensity changes more precisely than N1/P2 slopes, and should therefore be evaluated in future studies of individual differences in augmenting/reducing.

Cortical Auditory Evoked Potentials

Central serotonergic neurotransmission was assessed using intensity dependence of cortical auditory evoked potentials (IDAP) in cluster headache (CH) patients during both the active and interictal period. In 15 episodic CH patients and 13 controls previously described methods were used and amplitude-stimulus intensity function (ASF) slopes were computed. In the cluster group mean ASF slope was significantly steeper than in the control group both during the active period (1.53 + 0.90 vs. 0.77 + 0.85, P = 0031) and interictally (1.85 + 1.20 vs. 0.77 + 0.85, P = 0012). In the cluster group IDAPs of active and interictal period did not differ significantly ( P = 0378). Duration of the disease or the present bout, distance from the last attack did not correlate with ASF slopes. In conclusion, our results are compatible with decreased level of serotonergic neurotransmission in raphe-cortical pathways. Diminished serotonergic activity in raphe-hypothalamic serotonergic pathways might be hypothesized influencing the activity of hypothalamic neurons and thus play a role in the genesis of cluster headache.
