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 ...
The p300-CBP coactivator family in humans is composed of two closely related transcriptional co-activating proteins (or coactivators): p300 (also called EP300 or E1A binding protein p300) CBP (also known as CREB-binding protein or CREBBP) Both p300 and CBP interact with numerous transcription factors and act to increase the expression of their ...
He offered three things that affected the amplitude – subjective probability, stimulus meaning, and information transmission. He summarized his view in the following formula: P300 amplitude = f[T x (1/P + M)], where P is subjective probability, M is stimulus meaning, and T is information transmitted. [18]
The P300 response of different healthy subjects in a two-tone auditory oddball paradigm. The plots show the average response to oddball (red) and standard (blue) trials and their difference (black). From Surprise response as a probe for compressed memory states . [ 3 ]
P300 may mean: P300 (neuroscience), a neural evoked potential component of the electroencephalogram (EEG) p300 (or EP300), a transcriptional coactivator;
Chopra says Rodgers was immediately “really trusting” with him and Hughes, adding that throughout their year working together on the documentary, Rodgers “was very open and vulnerable.”
This is a reasonable amalgamation given the sequence homology, structural similarity and binding behaviors of these two proteins. However, ongoing research shows that CBP and p300 maintain distinct biological functions and should therefore not be conflated. Amino acid sequence homology between CBP and p300 transcription factors.
