Presentiment in Mainstream Science?

Written by 

Two recent publications in mainstream journals may have found and reported on something that those in the parapsychology field - Presentiment - an intuitive feeling about the future, especially one of foreboding. Parapsychological researchers have been doing studies on this phenomenon for many years. The studies showed the presentiment effect in skin conductance, heart rate, EEG measures and fMRI.

Here are the references to the two most recent studies:

 

Spontaneous Neural Fluctuations Predict Decisions to Attend

Ongoing variability in neural signaling is an intrinsic property of the brain. Often this variability is considered to be noise and ignored. However, an alternative view is that this variability is fundamental to perception and cognition and may be particularly important in decision-making. Here, we show that a momentary measure of occipital alpha-band power (8–13 Hz) predicts choices about where human participants will focus spatial attention on a trial-by-trial basis. This finding provides evidence for a mechanistic account of decision-making by demonstrating that ongoing neural activity biases voluntary decisions about where to attend within a given moment.

 

Spontaneous fluctuations in neural responses to heartbeats predict visual detection

Hyeong-Dong Park,1, Stéphanie Correia,1, Antoine Ducorps2, & Catherine Tallon-Baudry1,

Nature NeuroscienceVolume: 17,Pages:612–618Year published: (2014)DOI:doi:10.1038/nn.3671 Received 18 November 2013 Accepted 05 February 2014 Published online 09 March 2014

Spontaneous fluctuations of ongoing neural activity substantially affect sensory and cognitive performance. Because bodily signals are constantly relayed up to the neocortex, neural responses to bodily signals are likely to shape ongoing activity. Here, using magnetoencephalography, we show that in humans, neural events locked to heartbeats before stimulus onset predict the detection of a faint visual grating in the posterior right inferior parietal lobule and the ventral anterior cingulate cortex, two regions that have multiple functional correlates and that belong to the same resting-state network. Neither fluctuations in measured bodily parameters nor overall cortical excitability could account for this finding. Neural events locked to heartbeats therefore shape visual conscious experience, potentially by contributing to the neural maps of the organism that might underlie subjectivity. Beyond conscious vision, our results show that neural events locked to a basic physiological input such as heartbeats underlie behaviorally relevant differential activation in multifunctional cortical areas.
