The interplay between rhythm and motor skills

São Luís Castro, principal investigator of the research project 304/14 - The impact of music training on reading and mathematical abilities of normal and reading disabled children: a behavioral and neuroimaging longitudinal study, supported by the BIAL Foundation, aimed to study the interplay between rhythm and motor skills in the context of music training, at behavioral and brain levels. In a longitudinal study with children, it was explored whether the ability to perceive or reproduce rhythm (predisposition) modulates the motor improvements associated with music training, and identified brain regions implicated in the putative links between rhythm and motor learning. Fifty-seven 8-year-old children participated in a longitudinal study where they completed rhythm and motor tasks, as well as structural MRI scans before and after a 6-month music training (n= 21) or a sports program (n= 18), or no specific training (passive control group, n = 18). It was found that music training improved motor performance (and also rhythm), and that the magnitude of the improvement depended on the ability to perceive rhythm before training (i.e., better rhythm predisposition, more significant improvements). Music training also induced a loss of gray matter volume in the left cerebellum and fusiform gyrus, and volume loss correlated with higher motor gains. No such effects were found in the sports and control groups. These findings are presented in the paper Individual differences in rhythm perception modulate music‑related motor learning: a neurobehavioral training study with children published in Scientific Reports.

How do blind individuals perceive emotional authenticity?

In the scope of the research project 148/18 - Voice perception in the visually deprived brain: Behavioral and electrophysiological insights, supported by the BIAL Foundation, the research team, led by Tatiana Conde, aimed to explore how blind individuals perceive emotional authenticity. Combining behavioural and ERP measures it was investigated authenticity perception in laughter and crying in individuals early-blind (n = 17) late-blind (n = 17), and sighted control participants (n = 51). Behaviourally, early-blind and sighted participants performed similarly well in emotional authenticity perception, but the late-blind group performed worse than sighted controls. In brain responses, all groups were sensitive to laughter authenticity at the P2 stage, and to crying authenticity at the early LPP stage. Nevertheless, only early-blind participants were sensitive to crying authenticity at the N1 and middle LPP stages, and to laughter authenticity at the early LPP stage. Furthermore, early-blind and sighted participants were more sensitive than late-blind ones to crying authenticity at the P2 and late LPP stages. Altogether, these findings suggest that prolonged visual deprivation with late-onset impairs the processing of emotional authenticity. For more information read the paper Blindness influences emotional authenticity perception in voices: Behavioral and ERP evidence published in the journal Cortex.

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.

Can perceived interactions with the deceased help in the bereavement process?

Across societies, 30 to 34% of individuals is likely to experience at least one after-death communication (ADC) in their lifetime. The ADC is defined as a spontaneous phenomenon in which a living individual has a feeling or sense of direct contact with a deceased person. An ADC may occur in several forms, which include a sense of presence, sensory experiences (visual, auditory, tactile, olfactory), symbolic experiences (song on radio, flower blooming out of season, etc.), electronic experiences (telephone call, Facebook “like”, or email from the deceased, computer anomalies, etc.), visitation or message dreams. ADCs occur across cultures, race, age, socio-economic status, educational level, gender, and religious beliefs. In the scope of project 169/20 - Investigation of the Phenomenology and Impact of Spontaneous and Direct After-Death Communications (ADCs), supported by the BIAL Foundation, the research team explored the impact of perceived ADCs on bereavement, involving 70 individuals who experienced ADCs with deceased partners or spouses. The majority found the ADCs comforting (81%) and helpful in their bereavement (84%). For 49% of the participants, ADCs seemed to ease acceptance of loss and 42% confirmed an accelerated recovery due to the ADC. The implications of these findings are discussed in the article Description and impact of encounters with deceased partners or spouses published in OMEGA - Journal of Death and Dying.

Electrophysiological signature of cessations

The paper Investigation of advanced mindfulness meditation “cessation” experiences using EEG spectral analysis in an intensively sampled case study, published in the journal Neuropsychologia, examines the neural signature of “cessation” events (momentary void of consciousness) during mindfulness meditation. The study, carried out by Matthew Sacchet in the scope of the research project 99/20 - Beyond "mindfulness" and toward a modern science of meditative mastery and spiritual transformation, supported by the BIAL Foundation, showed that EEG alpha-power decreases started 40 seconds before cessations and were lowest immediately following a cessation. Region-of-interest (ROI) based examination of this finding revealed that the alpha-suppression was most pronounced over the occipital and parietal regions of the brain, and linearly decreased with time for the entire pre-cessation duration.

What are the predictors of therapeutic alliance?

In the scope of project 178/12 - How collaboration in psychotherapy becomes therapeutic: a study of interactive and psychophysiological processes in good and poor outcome cases, supported by the BIAL Foundation, Eugénia Pereira and colleagues published the paper Data mining techniques in psychotherapy: applications for studying therapeutic alliance in the journal Scientific Reports. Applying data mining and Machine Learning (ML) techniques, the study aimed to identify the key factors or variables that significantly impact the strength of the therapeutic alliance (TA) between clients and psychotherapists. The results showed that the heart rate (HR) of the therapist was negatively associated with the therapist’s TA and the electrodermal activity (EDA) emerged as the most influential biological feature in the prediction of the TA, in the client but not in the therapist. Thus, the results from the ML algorithm document the differential importance of the physiological variables in the therapist and client (HR and EDA, respectively), for predicting TA, suggesting different experiences during therapy sessions for the dyad and with different underlying neurophysiological mechanisms.

The quest of physiological markers for the experience of pain

Researcher: Elia Valentini - Department of Psychology & Centre for Brain Science, University of Essex Summary: The aim of this project is to improve measurement of the human experience of pain by investigating a combination of psychophysical and physiological responses during mild noxious stimulation. More specifically, we want to investigate how sensitive and specific to pain the brain oscillatory responses are. We use EEG as the main technique, but we are keen to collaborate with neuroscientists using fMRI, autonomic measures and brain stimulation as well as with computational neuroscientists. A clinical collaborator would also be very much welcome.

EEG investigation of hypnosis and decision-making

Researcher: Rinaldo Livio Perri - University Niccolò Cusano Rome, Italy Summary: I work in the field of hypnosis and cognitive neuroscience. In particular, I adopt the event-related potentials (ERPs) to investigate the effect of the hypnotic suggestions on sensory processing and cognitive performance. I am an expert in decision-making and proactive brain processes before the stimulus administration (e.g., the perceptual, prefrontal and premotor readiness during the expectancy stage). I could help colleagues to properly analyze the ERP signal in the pre-stimulus stage of processing. Also, I would be happy to share my EEG data for re-analyzing them in the frequency domain (e.g., wavelet or coherence analysis in the hypnosis research). Feel free to contact me for any question!
