Research on the mental representation of human language has convincingly shown that sign languages are structured similarly to spoken languages. However, whether the same neurobiology underlies the online construction of complex linguistic structures in sign and speech remains unknown. To investigate this question with maximally controlled stimuli, we studied the production of minimal two-word phrases in sign and speech. Signers and speakers viewed the same pictures during magnetoencephalography recording and named them with semantically identical expressions. For both signers and speakers, phrase building engaged left anterior temporal and ventromedial cortices with similar timing, despite different linguistic articulators. Thus the neurobiological similarity of sign and speech goes beyond gross measures such as lateralization: the same fronto-temporal network achieves the planning of structured linguistic expressions.

Gestures are essential in early language development. We investigate the use of gestures in children with cochlear implants (CIs), with a particular focus on deictic, iconic, and conventional gestures. The aim is to understand how the use of gestures in everyday interactions relates to age, vocabulary testing results, and language development reported by parents.

The applause sign (AS) is a recognized phenomenon observed in progressive supranuclear palsy (PSP) and other neurological conditions where individuals produce over three claps following a request to clap only thrice after a demonstration. In this study, we introduced a novel linguistic phenomenon termed the oral applause sign (OAS) associated with the AS. The OAS is characterized by increased repetition counts of Japanese repetitive onomatopoeic words, such as uttering "pata-pata-pata" instead of the expected "pata-pata.

We report a case of crossmodal bilingual aphasia-aphasia in two modalities, spoken and sign language-and dysgraphia in both writing and fingerspelling. The patient, Sunny, was a 42 year-old woman after a left temporo-parietal stroke, a speaker of Hebrew, Romanian, and English and an adult learner, daily user of Israeli Sign language (ISL). We assessed Sunny's spoken and sign languages using a comprehensive test battery of naming, reading, and repetition tasks, and also analysed her spontaneous-speech and sign.
