Dr-MUSIC: An Effective Device for Investigating Multisensory Mechanisms during Development with EEG recordings

Area of Science:

• Neuroscience
• Developmental Psychology
• Biomedical Engineering

Background:

• Human development involves integrating multisensory information for coherent perception.
• Investigating multisensory integration in infants and children during EEG recording presents significant methodological challenges.

Purpose of the Study:

• To introduce Dr-MUSIC, a novel, EEG-compatible multisensory device designed for children.
• To assess the system's EEG compatibility and usability in adults and toddlers.

Main Methods:

• Dr-MUSIC integrates audio, visual, and tactile stimulators in an engaging design.
• EEG compatibility was validated in adults using an audio-tactile oddball task.
• Usability was confirmed in toddlers performing the same task.

Main Results:

• The Dr-MUSIC system demonstrated effective EEG compatibility in adults.
• The device proved usable for young children in a clinical setting.
• The system facilitates novel experimental protocols for studying early-life multisensory integration.

Conclusions:

• Dr-MUSIC offers a viable solution for investigating the neural basis of multisensory integration in early development.
• Its adaptable features and engaging design are suitable for children with and without sensory impairments.
• The device holds potential for developing early rehabilitation protocols for typical and atypical development.
