Gamma ASSR, 睡眠與 level of arousal

Gamma ASSR會受到睡眠與 level of arousal 的影響

The amplitude and phase precision of 40 Hz auditory steady-state response depend on the level of arousal. 2007 Experimental Brain Research

The 64-channel EEG data was wavelet transformed and the amplitude and phase precision of the wavelet transformed evoked potential were decomposed by the recently proposed multi-subject non-negative multi-way factorization (NMWF) (Morup et al. in J Neurosci Methods 161:361–368, 2007). The estimates of these measures were subjected to statistical analysis. The amplitude and phase precision of the ASSR were significantly larger during the low arousal state compared to the high arousal condition. The modulation of ASSR amplitude and phase precision by differences in the arousal level during recording warrants caution when investigating oscillatory brain activity and interpreting the findings of reduced ASSR in schizophrenia. It also emphasizes the necessity of standardized recording procedures and monitoring the level of arousal during ASSR testing.

A machine learning approach using P300 responses to investigate effect of clozapine therapy. Conf Proc

Engineering in Medicine and Biology Society (EMBC), 2012 Annual International Conference of the IEEE

Clozapine (CLZ) is uniquely effective as a treatment for medication resistant schizophrenia. Information regarding its mechanism of action may offer clues to the pathophysiology of the disease and to improved treatment. In this study we employ a machine learning (ML) analysis of P300 evoked potentials obtained from quantitative electroencephalography (QEEG) data to identify changes in the brain induced by CLZ treatment.

MMN 2015: 7th MMN conference








 Error Signals from the Brain – 7th Mismatch Negativity Conference (MMN 2015) will be held at the University of Leipzig, Germany, between September 8th and September 11th 2015.

The MMN is an error-signal of the brain that is elicited when an auditory (visual, somato-sensory) stimulus does not match a detected regularity of the sensory environment. It has been used in thousands of experiments in basic and applied (clinical) research to study the brain’s (automatic) encoding and representation of regularities and the detection of respective regularity violations. Therefore the MMN can be regarded as the most influential error signal in cognitive neuroscience. 

The 7th Mismatch Negativity Conference presents the state of the art in methods, theory and application (basic and clinical research) of the MMN. However, it will also cover other error signals of the brain. Moreover, there will be a Hands-on pre-conference workshop devoted to the design of MMN studies and the analysis and interpretation of MMN data as well as a pre-conference workshop on the visual MMN.  (繼續閱讀…)
