High Gamma Power Is Phase-Locked to Theta Oscillations in Human Neocortex
- R. Canolty, E. Edwards, +6 authors R. Knight
- Physics, Medicine
- Science
- 15 September 2006
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) rhythm… Expand
Five-dimensional neuroimaging: Localization of the time–frequency dynamics of cortical activity
- S. Dalal, A. Guggisberg, +8 authors S. Nagarajan
- Psychology, Computer Science
- NeuroImage
- 1 May 2008
TLDR
Seizures and epileptiform activity in the early stages of Alzheimer disease.
IMPORTANCE
Epileptic activity associated with Alzheimer disease (AD) deserves increased attention because it has a harmful impact on these patients, can easily go unrecognized and untreated, and may… Expand
Spatiotemporal Dynamics of Word Processing in the Human Brain
- R. Canolty, M. Soltani, +6 authors R. Knight
- Psychology, Medicine
- Front. Neurosci.
- 1 September 2007
We examined the spatiotemporal dynamics of word processing by recording the electrocorticogram (ECoG) from the lateral frontotemporal cortex of neurosurgical patients chronically implanted with… Expand
Emergent network topology at seizure onset in humans
- M. Kramer, E. Kolaczyk, H. Kirsch
- Psychology, Medicine
- Epilepsy Research
- 1 May 2008
Epilepsy - the world's most common serious brain disorder - is defined by recurrent unprovoked seizures that result from complex interactions between distributed neural populations. We explore some… Expand
Incidence and impact of subclinical epileptiform activity in Alzheimer's disease
- K. Vossel, K. Ranasinghe, +15 authors S. Nagarajan
- Psychology, Medicine
- Annals of neurology
- 1 December 2016
Seizures are more frequent in patients with Alzheimer's disease (AD) and can hasten cognitive decline. However, the incidence of subclinical epileptiform activity in AD and its consequences are… Expand
The Howling Cortex: Seizures and General Anesthetic Drugs
- L. Voss, J. Sleigh, J. Barnard, H. Kirsch
- Medicine
- Anesthesia and analgesia
- 1 November 2008
The true incidence of seizures caused by general anesthetic drugs is unknown. Abnormal movements are common during induction of anesthesia, but they may not be indicative of true seizures.… Expand
Spatiotemporal imaging of cortical activation during verb generation and picture naming
- E. Edwards, S. Nagarajan, +4 authors R. Knight
- Psychology, Computer Science
- NeuroImage
- 1 March 2010
TLDR
Single-Trial Speech Suppression of Auditory Cortex Activity in Humans
- A. Flinker, E. Chang, H. Kirsch, N. Barbaro, N. Crone, R. Knight
- Psychology, Medicine
- The Journal of Neuroscience
- 8 December 2010
The human auditory cortex is engaged in monitoring the speech of interlocutors as well as self-generated speech. During vocalization, auditory cortex activity is reported to be suppressed, an effect… Expand
Neocortical hyperexcitability in a human case of tuberous sclerosis complex and mice lacking neuronal expression of TSC1
- Yanling Wang, J. Greenwood, M. E. Calcagnotto, H. Kirsch, N. Barbaro, S. Baraban
- Biology, Medicine
- Annals of neurology
- 1 February 2007
To identify brain regions, cell types, or both that generate abnormal electrical discharge in tuberous sclerosis complex (TSC). Here we examined excitatory and inhibitory synaptic currents in human… Expand
