Pulsed brain stimulation enhances speech comprehension.

Link – Pulsed transcranial electric brain stimulation enhances speech comprehension. Abstract BACKGROUND: One key mechanism thought to underlie speech processing is the alignment of cortical brain rhythms to the acoustic input, a mechanism termed entrainment. Recent work showed that transcranial electrical stimulation (tES) in speech relevant frequencies or adapted to the speech envelope can in […]

Biasing the Perception of Speech with tACS

Link – Biasing the Perception of Spoken Words with Transcranial Alternating Current Stimulation. Abstract Recent neuroimaging evidence suggests that the frequency of entrained oscillations in auditory cortices influences the perceived duration of speech segments, impacting word perception [Kösem, A., Bosker, H. R., Takashima, A., Meyer, A., Jensen, O., & Hagoort, P. Neural entrainment determines the […]

Music as a scaffold for listening to speech

Link – Music as a scaffold for listening to speech: Better neural phase-locking to song than speech. Abstract Neural activity synchronizes with the rhythmic input of many environmental signals, but the capacity of neural activity to entrain to the slow rhythms of speech is particularly important for successful communication. Compared to speech, song has greater […]

The Brain Differentially Prepares Inner and Overt Speech Production

Link – The Brain Differentially Prepares Inner and Overt Speech Production: Electrophysiological and Vascular Evidence. Abstract Speech production not only relies on spoken (overt speech) but also on silent output (inner speech). Little is known about whether inner and overt speech are processed differently and which neural mechanisms are involved. By simultaneously applying electroencephalography (EEG) […]

Exploring speech production with EEG

Link – Exploring the temporal dynamics of speech production with EEG and group ICA. Abstract Speech production is a complex skill whose neural implementation relies on a large number of different regions in the brain. How neural activity in these different regions varies as a function of time during the production of speech remains poorly […]
