Event-related potentials and changes of brain rhythm oscillations during working memory activation in patients with first-episode psychosis

Background: Earlier contributions have documented significant changes in sensory, attention-related endogenous event-related potential (ERP) components and theta band oscillatory responses during working memory activation in patients with schizophrenia. In ...

Age-related changes in visually evoked electrical brain activity

Michael Herzog, Gijs Plomp

Whereas much is known about the degenerative effects of aging on cortical tissue, less is known about how aging affects visually evoked electrical activity, and at what latencies. We compared visual processing in elderly and young controls using a visual m ...

The N1 wave amplitude reflects perceptual grouping and correlates with crowding

Michael Herzog, Gijs Plomp, Vitaly Chicherov

In crowding, flanking elements strongly deteriorate performance. For example, vernier offset discrimination is strongly affected by neighboring flankers. Performance is worst when the flankers have the same length as the vernier. Surprisingly, performance ...

Electrical neuroimaging of memory discrimination based on single-trial multisensory learning

Micah Murray, Antonia Thelen

Multisensory experiences influence subsequent memory performance and brain responses. Studies have thus far concentrated on semantically congruent pairings, leaving unresolved the influence of stimulus pairing and memory sub-types. Here, we paired images w ...

Contextual modulation predicted by the N1 component of event-related potentials

Michael Herzog, Gijs Plomp, Vitaly Chicherov

Performance on a target can be strongly modified by context. For example, vernier offset discrimination is strongly deteriorated by neighboring flankers. Performance is worst when the flankers have the same length as the vernier. Surprisingly, performance ...

Topographical instability of event-related potentials in P300 wave study

Vitaly Chicherov

Microstate analysis of ERP and EEG topographies reveals stable patterns of brain activity. Little is known about the changes from one stable state to another. During such changes significant topographic instabilities are observed together with low ERP fiel ...

Multisensory interactions facilitate categorical discrimination of objects

Micah Murray

Object representations within both the auditory and visual systems include partially segregated networks for living and man-made items. Presently, it is unresolved whether/how multisensory interactions impact access to and discrimination of these represent ...

Sparse Source Recovery from Boundary Measurements using an Extension of Prony's Method for the Poisson Equation

Djano Kandaswamy

Electroencephalography (EEG) is a key modality to monitor brain activity with high temporal resolution. EEG makes use of an array of electrodes to measure the electrical potential on the scalp. While most traditional EEG analyses have looked at EEG rhythms ...

Spatio-temporal brain dynamics mediating post-error behavioral adjustments

Fosco Bernasconi

Optimal behavior relies on flexible adaptation to environmental requirements, notably based on the detection of errors. The impact of error detection on subsequent behavior typically manifests as a slowing down of RTs following errors. Precisely how errors ...
