Visual Mismatch Negativity Elicited by Facial Expressions: New Evidence from the Equiprobable Paradigm Xiying Li1,2, Yongli Lu3*, Gang Sun4, Lei Gao5 and Lun Zhao4,5*
Li et al. Behavioral and Brain Functions 2012, 8:7 http://www.behavioralandbrainfunctions.com/content/8/1/7 RESEARCH Open Access Visual mismatch negativity elicited by facial expressions: new evidence from the equiprobable paradigm Xiying Li1,2, Yongli Lu3*, Gang Sun4, Lei Gao5 and Lun Zhao4,5* Abstract Background: Converging evidence revealed that facial expressions are processed automatically. Recently, there is evidence that facial expressions might elicit the visual mismatch negativity (MMN), expression MMN (EMMN), reflecting that facial expression could be processed under non-attentional condition. In the present study, using a cross modality task we attempted to investigate whether there is a memory-comparison-based EMMN. Methods: 12 normal adults were instructed to simultaneously listen to a story and pay attention to a non- patterned white circle as a visual target interspersed among face stimuli. In the oddball block, the sad face was the deviant with a probability of 20% and the neutral face was the standard with a probability of 80%; in the control block, the identical sad face was presented with other four kinds of face stimuli with equal probability (20% for each). Electroencephalogram (EEG) was continuously recorded and ERPs (event-related potentials) in response to each kind of face stimuli were obtained. Oddball-EMMN in the oddball block was obtained by subtracting the ERPs elicited by the neutral faces (standard) from those by the sad faces (deviant), while controlled-EMMN was obtained by subtracting the ERPs elicited by the sad faces in the control block from those by the sad faces in the oddball block. Both EMMNs were measured and analyzed by ANOVAs (Analysis of Variance) with repeated measurements. -

The description of each peak includes typical latencies, cortical distributions, and possible brain sources of observed activity as well as the evoking paradigms and underlying psychological processes. The review is intended to serve as a tutorial for general readers interested in neuropsychological research and a references source for researchers using ERP techniques. ERP Peaks Review 3 Linking Brainwaves To The Brain: An ERP Primer Alexandra P. Fonaryova Key, Guy O. Dove, and Mandy J. Maguire Over the latter portion of the past century recordings of brain electrical activity such as the continuous electroencephalogram (EEG) and the stimulus-relevant event-related potentials (ERPs) became frequent tools of choice for investigating the brain’s role in the cognitive processing in different populations. These electrophysiological recording techniques are generally non-invasive, relatively inexpensive, and do not require participants to provide a motor or verbal response. -

Functionally Dissociated Aspects in Anterior and Posterior Electrocortical Processing of Facial Threat
International Journal of Psychophysiology 53 (2004) 29–36 Functionally dissociated aspects in anterior and posterior electrocortical processing of facial threat Dennis J.L.G. Schutter*, Edward H.F. de Haan, Jack van Honk Helmholtz Research Institute, Affective Neuroscience Section, Utrecht University, Heidelberglaan 2, 3584 CS, Utrecht, The Netherlands Received 12 June 2003; received in revised form 1 October 2003; accepted 15 January 2004 Available Online 9 April 2004 Abstract The angry facial expression is an important socially threatening stimulus argued to have evolved to regulate social hierarchies. In the present study, event-related potentials (ERP) were used to investigate the involvement and temporal dynamics of the frontal and parietal regions in the processing of angry facial expressions. Angry, happy and neutral faces were shown to eighteen healthy right-handed volunteers in a passive viewing task. Stimulus-locked ERPs were recorded from the frontal and parietal scalp sites. The P200, N300 and early contingent negativity variation (eCNV) components of the electric brain potentials were investigated. Analyses revealed statistical significant reductions in P200 amplitudes for the angry facial expression on both frontal and parietal electrode sites. Furthermore, apart from being strongly associated with the anterior P200, the N300 showed to be more negative for the angry facial expression in the anterior regions also. Finally, the eCNV was more pronounced over the parietal sites for the angry facial expressions. The present study demonstrated specific electrocortical correlates underlying the processing of angry facial expressions in the anterior and posterior brain sectors. The P200 is argued to indicate valence tagging by a fast and early detection mechanism. -

Early and Late Effects of Objecthood and Spatial Frequency on Event-Related Potentials and Gamma Band Activity
Craddock et al. BMC Neuroscience (2015) 16:6 DOI 10.1186/s12868-015-0144-8 RESEARCH ARTICLE Open Access Early and late effects of objecthood and spatial frequency on event-related potentials and gamma band activity Matt Craddock1,2, Jasna Martinovic3 and Matthias M Müller1* Abstract Background: The visual system may process spatial frequency information in a low-to-high, coarse-to-fine sequence. In particular, low and high spatial frequency information may be processed via different pathways during object recognition, with LSF information projected rapidly to frontal areas and HSF processed later in visual ventral areas. In an electroencephalographic study, we examined the time course of information processing for images filtered to contain different ranges of spatial frequencies. Participants viewed either high spatial frequency (HSF), low spatial frequency (LSF), or unfiltered, broadband (BB) images of objects or non-object textures, classifying them as showing either man-made or natural objects, or non-objects. Event-related potentials (ERPs) and evoked and total gamma band activity (eGBA and tGBA) recorded using the electroencephalogram were compared for object and non-object images across the different spatial frequency ranges. Results: The visual P1 showed independent modulations by object and spatial frequency, while for the N1 these factors interacted. The P1 showed more positive amplitudes for objects than non-objects, and more positive amplitudes for BB than for HSF images, which in turn evoked more positive amplitudes than LSF images. The peak-to-peak N1 showed that the N1 was much reduced for BB non-objects relative to all other images, while HSF and LSF non-objects still elicited as negative an N1 as objects. -

To test this hypothesis, we recorded electroencephalography in humans during stimulation with identical visual stimuli and analyzed how prestimulus neural oscillations modulate different stages of sensory processing reflected by distinct components of the event-related potential (ERP). We found that strong prestimulus alpha- and beta-band power resulted in a suppression of early ERP components (C1 and N150) and in an *For correspondence: amplification of late components (after 0.4 s), even after controlling for fluctuations in 1/f aperiodic [email protected] (LI); signal and sleepiness. -
Unspecific Hypervigilance and Spatial Attention in Early Visual Perception
Social Cognitive and Affective Neuroscience Advance Access published May 24, 2013 doi:10.1093/scan/nst044 SCAN (2013) 1 of 7 Timing the fearful brain: unspecific hypervigilance and spatial attention in early visual perception Mathias Weymar,1,2 Andreas Keil,2 and Alfons O. Hamm1 1Department of Biological and Clinical Psychology, University of Greifswald, 17487 Greifswald, Germany and 2Center for the Study of Emotion and Attention (CSEA), University of Florida, Gainesville, FL 32611, USA Numerous studies suggest that anxious individuals are more hypervigilant to threat in their environment than nonanxious individuals. In the present event-related potential (ERP) study, we sought to investigate the extent to which afferent cortical processes, as indexed by the earliest visual component C1, are biased in observers high in fear of specific objects. In a visual search paradigm, ERPs were measured while spider-fearful participants and controls searched for discrepant objects (e.g. spiders, butterflies, flowers) in visual arrays. Results showed enhanced C1 amplitudes in response to spatially directed target stimuli in spider-fearful participants only. Furthermore, enhanced C1 amplitudes were observed in response to all discrepant targets and distractors in spider-fearful compared with non-anxious participants, irrespective of fearful and non-fearful target contents. This pattern of results is in line with theoretical notions of heightened sensory sensitivity (hypervigilance) to external stimuli in high-fearful individuals. Specifically, the findings suggest that fear facilitates afferent cortical processing in the human visual cortex in a non-specific and temporally sustained fashion, when Downloaded from observers search for potential threat cues.

Response time typically shortens with practice, but which components of the stimulus–response processing chain facilitate this behav- ioral change? Improved search performance could result from enhancements in various cognitive processing stages, including (1) sensory processing, (2) attentional allocation, (3) target discrimination, (4) motor-response preparation, and/or (5) response execution. We measured event-related potentials (ERPs) as human participants completed a five-day visual-search protocol in which they reported the orientation of a color popout target within an array of ellipses. We assessed changes in behavioral performance and in ERP compo- nents associated with various stages of processing. After practice, response time decreased in all participants (while accuracy remained consistent), and electrophysiological measures revealed modulation of several ERP components. First, amplitudes of the early sensory- evoked N1 component at 150 ms increased bilaterally, indicating enhanced visual sensory processing of the array.
