Cortical oscillations and sensory predictions

Abstract: Predictive coding: the idea that the brain generates hypotheses about the possible causes of forthcoming sensory events and that these hypotheses are compared with incoming sensory information. The difference between topdown expectation and incoming sensory inputs, that is, prediction error, is propagated forward throughout the cortical hierarchy. Predictive timing (temporal expectations): an extension of the notion of predictive coding to the exploitation of temporal regularities (such as a beat) or associati… Show more

“…Contrary to what theories of predictive coding suggest (Arnal & Giraud, 2012) the neutral condition induced the lowest activity in our study, even showing a tendency for leading to lower activity than the correctly predicted condition. This result, however, has been observed in previous studies as well .…”

“…This way participants could form predictions regarding the likelihood of repetitions and alternations (in this example repetitions are predicted when a female face appeared while alternations are predicted when male faces were presented). Importantly, the third face category (in the above example the infant faces) was used as an unpredictive (Arnal & Giraud, 2012) or neutral cue as repetitions and alternations could follow S1 with equal likelihood in this category. The relationship between face category and repetition probability was counterbalanced across participants in a way that each category signaled high/low/equal probabilities with equal probability across participants (to avoid any possible stimulus effects that could arise due to a different attentional modulation invoked by adult and infant faces - Brosch et al,( 2007)).…”

“…We observed a significant main effect of delay [F(1,14) = 7.31, P = 0.017, η p 2 = 0.34], indicating higher accuracy following long delays. We also observed a main effect of cue type [F (1,14) 3A). Our first analyses of this signal tested whether temporal cueing led to any differences in the phase of posterior alpha-band oscillations as a function of cue type.…”

“…One intriguing proposal is that cortical oscillations instantiate perceptual predictions by coordinating prestimulus neural activity to process the predicted stimulus optimally (1,2). A candidate neural mechanism for such coordination is low-frequency oscillations in the alpha band (8)(9)(10)(11)(12)(13)(14) Hz) of human electroencephalography (EEG) recordings, which are suggested to route information phasically through task-relevant networks (3,4).…”

“…Moreover, recent theoretical and empirical work has highlighted that sensory predictions are a fundamental feature of normal brain functioning [11] which are implemented through low-level oscillatory mechanisms [59]. This raises the possibility that abnormal sensory predictions as a result of aberrant neural synchrony could parsimoniously explain both central clinical symptoms as well as the pervasive deficits in cognitive and perceptual processes in schizophrenia.…”
