High Gamma Power Is Phase-Locked to Theta Oscillations in Human Neocortex
We observed robust coupling between the high- and low-frequency bands of ongoing electrical activity in the human brain. In particular, the phase of the low-frequency theta (4 to 8 hertz) rhythmExpand

Language Comprehension in Language-Learning Impaired Children Improved with Acoustically Modified Speech
A speech processing algorithm was developed to create more salient versions of the rapidly changing elements in the acoustic waveform of speech that have been shown to be deficiently processed byExpand

Modulation of the Auditory Cortex during Speech: An MEG Study
Several behavioral and brain imaging studies have demonstrated a significant interaction between speech perception and speech production. In this study, auditory cortical responses to speech wereExpand

Sensory Processing in Autism: A Review of Neurophysiologic Findings
Atypical sensory-based behaviors are a ubiquitous feature of autism spectrum disorders (ASDs). In this article, we review the neural underpinnings of sensory processing in autism by reviewing theExpand

Reconstructing spatio-temporal activities of neural sources using an MEG vector beamformer technique
The authors have developed a method suitable for reconstructing spatio-temporal activities of neural sources by using magnetoencephalogram (MEG) data using a vector-extended version of the Borgiotti-Kaplan beamformer. Expand

Speech Production as State Feedback Control
Spoken language exists because of a remarkable neural process. Inside a speaker's brain, an intended message gives rise to neural signals activating the muscles of the vocal tract. The process isExpand

Five-dimensional neuroimaging: Localization of the time–frequency dynamics of cortical activity
The spatiotemporal dynamics of cortical oscillations across human brain regions remain poorly understood because of a lack of adequately validated methods for reconstructing such activity from noninvasive electrophysiological data. Expand
