The temporal sensitivity to the tactile-induced double flash illusion mediates the impact of beta oscillations on schizotypal personality traits
Publication year: 2021

Abstract/Results: ABSTRACT:
The coherent experience of the self and the world depends on the ability to integrate vs. segregate sensory information. Optimal temporal integration between the senses is mediated by oscillatory properties of neural activity. Previous research showed reduced temporal sensitivity to multisensory events in schizotypy, a personality trait linked to schizophrenia. Here we used the tactile-induced Double-Flash-Illusion (tDFI) to investigate the tactile-to-visual temporal sensitivity in schizotypy, as indexed by the temporal window of illusion (TWI) and its neural underpinnings. We measured EEG oscillations within the beta band, recently shown to correlate with the tDFI. We found individuals with higher schizotypal traits to have wider TWI and slower beta waves accounting for the temporal window within which they perceive the illusion. Our results indicate reduced tactile-to-visual temporal sensitivity to mediate the effect of slowed oscillatory beta activity on schizotypal personality traits. We conclude that slowed oscillatory patterns might constitute an early marker for psychosis proneness.

Beta oscillations in working memory, executive control of movement and thought, and sensorimotor function
Publication year: 2019
URL:
https://www.jneurosci.org/content/39/42/8231.long
Abstract/Results: ABSTRACT:
Beta oscillations (~13 to 30 Hz) have been observed during many perceptual, cognitive, and motor processes in a plethora of brain recording studies. Although the function of beta oscillations (hereafter “beta” for short) is unlikely to be explained by any single monolithic description, we here discuss several convergent findings. In prefrontal cortex (PFC), increased beta appears at the end of a trial when working memory information needs to be erased. A similar “clear-out” function might apply during the stopping of action and the stopping of long-term memory retrieval (stopping thoughts), where increased prefrontal beta is also observed. A different apparent role for beta in PFC occurs during the delay period of working memory tasks: it might serve to maintain the current contents and/or to prevent interference from distraction. We confront the challenge of relating these observations to the large literature on beta recorded from sensorimotor cortex. Potentially, the clear-out of working memory in PFC has its counterpart in the postmovement clear-out of the motor plan in sensorimotor cortex. However, recent studies support alternative interpretations. In addition, we flag emerging research on different frequencies of beta and the relationship between beta and single-neuron spiking. We also discuss where beta might be generated: basal ganglia, cortex, or both. We end by considering the clinical implications for adaptive deep-brain stimulation.

The role of beta oscillations in mental time travel
Publication year: 2023
URL:
https://journals.sagepub.com/doi/full/10.1177/09567976221147259
Abstract/Results: ABSTRACT:
The brain processes short-interval timing but also allows people to project themselves into the past and the future (i.e., mental time travel [MTT]). Beta oscillations index seconds-long-interval timing (i.e., higher beta power is associated with longer durations). Here, we used parietal transcranial alternating current stimulation (tACS) to investigate whether MTT is also supported by parietal beta oscillations and to test the link between MTT and short intervals. Thirty adults performed a novel MTT task while receiving beta and alpha tACS, in addition to no stimulation. Beta tACS corresponded to a temporal underestimation in past but not in future MTT. Furthermore, participants who overestimated seconds-long intervals also overestimated temporal distances in the past-projection MTT condition and showed a stronger effect of beta tACS. These data provide a unique window into temporal perception, showing how beta oscillations may be a common mechanism for short intervals and MTT.

Anxiety and neural correlates of attention and self-regulation in pregnancy: A resting-state EEG study
Publication year: 2025
URL:
https://doi.org/10.1007/s00737-024-01505-6
Abstract/Results: ABSTRACT:
Purpose: Pregnant women are particularly vulnerable to experiencing mental health difficulties, especially anxiety. Anxiety in pregnancy can be characterized as having two components: general symptomology experienced in the general population, and pregnancy-related anxiety more focused on pregnancy, delivery, and the future child. In addition, women also commonly report experiencing attentional control and self-regulation difficulties across the peripartum period. However, links between anxiety and neural and cognitive functioning in pregnancy remain unclear. The present study investigated whether anxiety is associated with neural markers of attention and self-regulation measured using electroencephalography (EEG). Specifically, we examined associations between general and pregnancy-related anxiety and (1) beta oscillations, a neural marker of attentional processing; and (2) the coupling of beta and delta oscillations, a neural marker of self-regulation, in frontal and prefrontal regions.
Methods: A sample of 135 women in the third trimester of their pregnancy completed a resting-state EEG session.
Results: General anxiety was associated with increased beta oscillations, in line with research in the general population, interpreted as reflecting hyperarousal. Pregnancy-related anxiety was associated with decreased beta oscillations, interpreted as reflecting inattention and mind-wandering. Moreover, pregnancy-related anxiety, but not general anxiety, was linked to stronger delta-beta coupling, suggesting anxiety specifically related to the pregnancy is associated with investing greater effort in self-regulation.
Conclusion: Our results suggest that general and pregnancy-related anxiety may differentially relate to neural patterns underlying attention and self-regulation in pregnancy.

Title: BIAL Grants
Start date: 1994
History:
In 1994 the BIAL Foundation launched a programme of science research grants with the aim of encouraging the research into Man’s physical and mental processes, namely in fields still largely unexplored but which warrant further scientific analysis, as Psychophysiology and Parapsychology.
Since its launch, applications to the BIAL grants have been increasing. Up to now 461 projects have been supported, involving more than 1000 researchers from 27 countries.
The approved applications have benefited from grants in amounts comprised between €5,000 and €50, 000. The amount to be granted is fixed by the Scientific board according to the needs of each project.
The supported projects have originated, until April 2013, in about 600 full papers, 172 out of which were published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Among the BIAL Foundation fellows is worth highlighting the presence of scientists from prestigious universities from the United States, United Kingdom, Australia, Russia, Germany, Japan, France, Canada, and many others.
The BIAL grants are promoted biannually.

Title:
From sampling to stopping: The P300 ERP component and beta power contribute to reward-related decision commitments

Abstract/Results: ABSTRACT:
Optimal stopping problems provide a framework for studying decision-making under uncertainty, balancing the trade-off between information sampling and decision commitment. We investigated deviations from normative strategies in human decision-making and examined the neural mechanisms underlying decision commitment versus sampling using electroencephalography (EEG). Forty participants viewed sequences of beads drawn from fictitious urns and attempted to infer the majority bead colour in each urn, while their EEG activity was recorded. After viewing each bead, participants could choose to sample more by drawing another bead (draw choice) or to stop sampling and infer the contents of the urn (urn choice). A Bayesian ideal observer model and parametrised models were used to predict participant behaviour. Participants undersampled relative to the ideal observer, particularly in the more uncertain condition where the proportion of bead colours was close to chance (60/40 or 0.6), with the model better capturing behaviour in the easier 80/20 (0.8) condition. Stimulus-locked P300 amplitudes showed larger responses for urn choices and a gradient of increasing amplitude as draws approached commitment. Larger frontal ERP responses were also observed under higher uncertainty (0.6 condition). Beta oscillatory activity was stronger for urn choices in the high uncertainty condition, with fast beta (20–30 Hz) activity driving final commitment to a decision. Beta power was further predicted by model-derived action values. By integrating behavioural, computational, and neurophysiological data, this study advances our understanding of active information sampling versus decision commitment in reward-related probabilistic environments.
