Mapping facial muscles activation as a window to the human brain
Human facial expressions are a key component in social interactions. They inﬂuence our innate perception while also facilitating nonverbal communication. Facial expressions reflect a wide spectrum of emotions conveyed by diverse muscle activation patterns. Quantiﬁcation of expression of the producer, the receiver or both is an unmet need in experimental and clinical settings.
My project’s main goal is to form a novel methodology to quantify and objectively classify patterns of facial muscle activation for neurological and psychological characterizations.
Surface electromyography (sEMG) measures electrical potential diﬀerences of muscle activation. When combined with mathematical methodologies sEMG emerges as an attractive tool to map muscle activation of facial expressions. We recently developed novel, dry and soft sEMG electrodes ideally suited for characterizing patterns of facial muscle activation overcoming many of the challenges presented by contemporary electrodes. We utilize high-resolution sEMG and signal processing analysis schemes to distinguish between diverse facial expressions.
In the long term, this work is aimed to facilitate early markers of neurological and psychological conditions and to define their characteristics, providing an objective and quantitative measure.
