The influence of environmental spatial references on vestibular self-motion

While navigating through the surroundings, we constantly rely on inertial vestibular signals for self-motion along with visual and acoustic spatial references from the environment. However, the interaction between inertial cues and environmental spatial references is not yet fully understood. To address this, Elisa Ferrè, principal investigator of research project 41/20 - Luminous dancing fairies in weightlessness: How gravity shapes conscious experiences, supported by the BIAL Foundation, aimed to investigate the influence of environmental visual and auditory spatial references on vestibular self-motion. A Vestibular Self-Motion Detection Task was administered to twenty-six healthy participants in which they were asked to detect brief self-motion sensations induced by low-intensity Galvanic Vestibular Stimulation (GVS). Participants performed this task either with or without a visual or acoustic spatial reference positioned directly in front of them. Results showed that the visual spatial reference increased sensitivity to detect vestibular self-motion. Conversely, the acoustic spatial reference did not influence self-motion sensitivity. This seems to suggest a specific interaction between visual and vestibular systems in self-motion perception. More information available in the paper Spatial Sensory References for Vestibular Self-Motion Perception published in the journal Multisensory Research.

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.
