Relate LGN modulation to audiovisual speech recognition

Characterize how lateral geniculate nucleus (LGN) modulation relates to speech-recognition behavior when visual speech is processed together with auditory speech in audiovisual settings.

Background

The study found no significant correlation between LGN responses and visual-only speech-recognition performance, in contrast to reported relationships involving the auditory medial geniculate body during auditory speech recognition. Because visual speech commonly supports auditory speech recognition, particularly in noisy environments, the authors identify the relationship between LGN modulation and behavior during audiovisual speech perception as unresolved.
