Abstract #118: Transcranial electrical stimulation models using an emulated-CSF value approximate the meninges more accurately.

Abstract

Introduction: Understanding how current applied at the scalp during transcranial electrical stimulation (tES; including tDCS) reaches the brain, underpins efforts to rationalize outcomes and optimize interventions. To this end, computational models of current flow relate applied dose to brain electric field. Standard models, using a workflow established since 2009, have now been verified using a range of technique including intra-cranial recording to reasonable accuracy.
