Neural representations of beat and rhythm in motor and association regions.
Cereb Cortex
October 2024
Humans perceive a pulse, or beat, underlying musical rhythm. Beat strength correlates with activity in the basal ganglia and supplementary motor area, suggesting these regions support beat perception. However, the basal ganglia and supplementary motor area are part of a general rhythm and timing network (regardless of the beat) and may also represent basic rhythmic features (e.

However, it is unknown how rhythmic training that emphasizes visual rhythms, such as dance training, might affect beat processing, nor whether training effects in general are modality specific. Here we examined how music and dance training interacted with modality during audiovisual integration and synchronization to auditory and visual isochronous sequences.

- Music exists in every society but varies globally, leading researchers to explore universal aspects of music cognition across diverse cultures.
- A study involving 39 groups from 15 countries found that listeners could reproduce random rhythms, revealing a common cognitive feature: a preference for discrete rhythm categories based on small-integer ratios.
- The variations in the importance of these integer ratios across different cultures suggest that while there are universal patterns in how people perceive rhythm, local musical traditions significantly shape these cognitive representations.
Background: Freezing of gait (FOG) is an intractable motor symptom in Parkinson's disease (PD) that increases fall risk and impairs the quality of life. FOG has been associated with anxiety, with experimental support for the notion that anxiety itself provokes FOG. We investigated the effect of acute anxiety reduction via alprazolam on FOG in PD.
