Project Description
In everyday life, humans are particularly attuned to listening to two particular types of sound: speech and music. We apply a novel analysis method to shed light on how the brain is almost effortlessly able to use acoustic features to assign meaning to sounds. To do so, we use an original cross-validated Representational Similarity Analyses (RSA) approach implemented in Matlab to estimate the similarity between acoustic or semantic features of an auditory stream (speech, music) and neural activity (here intracranial EEG recordings decomposed into frequency bands).
Title
Neural encoding of acoustic and semantic features during speech and music perception: Matlab to Python code translation
