Virtual Lecture by Laetitia Grabot: Alpha Activity Reflects
the Magnitude of an Individual Bias in Human Perception
The brain is a biased organ, frequently generating systematically distorted percepts of the world, leading each of us to evolve in our own subjective reality. However, such biases are often overlooked or considered noise when studying the neural mechanisms underlying perception. We show that spontaneous frontal alpha band activity predicts the degree of biasedness of human choices in a time perception task, suggesting that alpha power indexes processes needed to overcome an individual’s idiosyncratic bias. We speculate that this frontal alpha activity is different from the usual parieto-occipital alpha found in spatial attention tasks, and is involved in cognitive control mechanisms.
