The P300 (P3) wave is an event-related potential (ERP) component elicited in the process of decision making. It is considered to be an endogenous potential, as its occurrence links not to the physical attributes of a stimulus, but to a person's reaction to it.
In addition, there are studies on abnormalities of P300 in depression. Depressed patients tend to have a reduced P200 and P300 amplitude and a prolonged P300 latency. [20] Due to the consistency of the P300 response to novel stimuli, a brain–computer interface can be constructed which relies on it. By arranging many signals in a grid ...
A closely related dependence between the P300 and subjective probability was shown by Levi-Aharoni et al. [1] who used a fuzzy, compressed representation of stimulus probability to explain the single-trial variability in the P300 response magnitude. However, it has also been found that P300 amplitude can change in the absence of changes in ...
The P3a, or novelty P3, [1] is a component of time-locked signals known as event-related potentials .The P3a is a positive-going scalp-recorded brain potential that has a maximum amplitude over frontal/central electrode sites with a peak latency falling in the range of 250–280 ms.
P300 may mean: P300 (neuroscience), a neural evoked potential component of the electroencephalogram (EEG) p300 (or EP300), a transcriptional coactivator;
Luxury Is Calling. One man’s trash is very often another man’s treasure on eBay, which has been selling head-scratching items since 1995. But eBay is a place for a lot more than just cheap ...
The P300 had previously been shown to be elicited by unexpected stimuli. Kutas and Hillyard therefore used sentences with anomalous endings (i.e.I take coffee with cream and dog), expecting to see a P300 to the unexpected sentence-final words. However, instead of eliciting a large positivity, these anomalous endings elicited a large negativity ...
