Questions tagged [event-related-potential]

The event-related potential technique non-invasively records neural responses to specific events. The event-related potential, or ERP, is extracted from the electro-encephalogram. ERPs are typically obtained in humans.

Can an EEG response be phase-locked but not time-locked?

In EEG, there are two commonly encountered notions of linkage between a stimulus and a response, usually encountered in literature surrounding event-related potentials (ERPs) or evoked potentials (EPs)...

Sources on P1/N1 modulation with checkerboard probe

I have been able to find a lot of papers that modulate the P1/N1 component with a visual probe, usually a checkerboard presented parafoveally. I understand the basics of what I am reading, but I would ...

What are ERP components such as N400?

A lot of research uses ERP, which is time-locked EEG. I am reading about semantic and syntactic anomalies. So when a semantic anomaly occurs there is supposed to be a negative peak in ERP at 400ms. I ...

Readiness Potential vs. Lateralized Readiness Potential in ERP

Readiness Potential (RP) has been obviously discovered before Lateralized Readiness Potential (LRP). I wonder, is simple RP still used for something today? Is the LRP preferable over RP because of ...

How do I interpret an effect of electrode position in ERP research?

The example I have in my research is that both conditions show greater amplitude and latency in the parietal electrode sites than in the occipital ones. I'm not sure how meaningful this is for my ...

Does stimulus-independent ERP make sense/ exist?

Is anyone aware of any concept of stimulus independent ERP (an apparent oxymororn, an event related potential that is neither sensory, cognitive nor motor elicited) ...or a procedure that looks ...

How do I obtain recordings of the P300 wave of the event-related potential in the EEG?

I am trying to understand how to analyze the ERP (Event-Related Potentials) from EEG recordings and in particular the P300 wave. I have come up with a few questions which I hope you might be able to ...

Do you know any good tutorial on designing EEG experiments with PsychoPy?

I'm trying to find good documentation on using PsychoPy to measure Event-Related Potentials. In particular, I want to measure and compare the amplitude of the N170, a face-sensitive ERP, when ...

How is the signal-to-noise ratio of an event-related-potential measured?

I often encounter publications where the authors try to "increase the SNR (signal-to-noise ratio) of electroencephalogram (EEG) signals". Some define a numeric value of SNR of EEG signals, but I am ...

What cognitively interesting event-related potentials at FP1, FP2, TP9 or TP10 can be measured with consumer-grade EEG hardware?

I'm looking for cognitively interesting event-related potentials at places like FP1, FP2, TP9 or TP10 that can be measured with consumer-grade EEG hardware. Right now I have an Interaxon Muse EEG and ...
