Scientific advancements with High-density ECoG grids

At the  department of Neurology and Neurosurgery of the  UMC Utrecht Brain Center we use high-density ECoG grids to learn more about the brain. More specifically, we investigate how the brain controls hand movement and produces intelligible speech, and we develop cutting-edge tools to streamline signal acquisition, processing and interpretation.

High-density grid recordings are performed either intraoperative, during for example tumor resection awake surgery or during  Epilepsy monitoring period at the UMC Utrecht.

Gridloc

Automatic and unsupervised localization of high-density ECoG grids 

Speech Perception

Detection and idenfiticaiton of perceived speech in sensorimotor cortex

Phonemes

Decoding four spoken phonemes using high-density ECoG grids

Facial Expressions

Classification of four facial expressions from sensorimotor cortex

Vowels

Identification of speech, articulators and facial movements signatures in the sensorimotor cortex
