Can gratitude buffer the negative effects of stress?

Researchers found that gratitude has a unique stress-buffering effect on both reactions to and recovery from acute psychological stress.

Do mood fluctuations impact confidence in decision-making?

Study reveals that in the healthy adult population, fluctuations of mood do not interfere with confidence in decision-making.

Relationship between sleep bruxism, insomnia and anxiety

Researchers concluded that, although sleep bruxism has no direct association with insomnia, anxiety may act as a bridging factor between these complaints.

How submovements are coordinated?

In the scope of the research project 246/20 - The hidden rhythm of interpersonal (sub-)movement coordination, supported by the BIAL Foundation, the research team led by Alice Tomassini studied the submovement coordination at an individual- and dyadic-level. Participants performed a series of bimanual tasks in coordination with a partner (dyadic task) or alone (solo task) and, in the latter case, with or without visual feedback. Data, presented in the paper The microstructure of intra- and interpersonal coordination published in the Proceedings of the Royal Society B, showed that distinct coordinative structures emerged at the level of submovements, as a result of feedback properties. Specifically, the relative timing of submovements (between partners/effectors) shifted from alternation to simultaneity and a mixture of both when coordination is achieved using vision (interpersonal), proprioception/efference-copy only (intrapersonal, without vision) or all information sources (intrapersonal, with vision), respectively.

Can the brain act as a psi-inhibitory filter?

Morris Freedman’s neurobiological model suggests that the frontal lobes of the brain act as a filter to inhibit psi and implies that humans may have innate psi abilities that are suppressed by this frontal lobe filter. To test this model, the research team of the research project 210/18 - Mind-matter Interactions and the Frontal Lobes of the Brain, supported by the BIAL Foundation, used repetitive transcranial magnetic stimulation (rTMS) to induce reversible brain lesions in the left medial middle frontal region in healthy participants. Data confirmed their a priori hypothesis, that is, healthy participants with reversible rTMS induced lesions affecting the left medial middle frontal brain region showed larger effects on a mind-matter interaction task compared to healthy participants without rTMS induced lesions. These findings support the concept that the brain serves as a filter to block psi effects and may help explain why these effects are so small and hard to replicate in healthy participants. To know more about the study, please read the paper Enhanced mind-matter interactions following rTMS induced frontal lobe inhibition, published in the journal Cortex.
