Negative BOLD in default-mode structures measured with EEG-MREG is larger in temporal than extra-temporal epileptic spikes
INTRODUCTION EEG-fMRI detects BOLD changes associated with epileptic interictal discharges (IED) and can identify epileptogenic networks in epilepsy patients. Besides positive BOLD changes, negative BOLD changes have sometimes been observed in the default-mode network, particularly using group analysis. A new fast fMRI sequence called MREG (Magnetic Resonance Encephalography) shows increased se...
متن کاملBOLD Responses to Negative Reward Prediction Errors in Human Habenula
Although positive reward prediction error, a key element in learning that is signaled by dopamine cells, has been extensively studied, little is known about negative reward prediction errors in humans. Detailed animal electrophysiology shows that the habenula, an integrative region involved in many processes including learning, reproduction, and stress responses, also encodes negative reward-re...
متن کاملWavelet analysis of epileptic spikes.
Interictal spikes and sharp waves in human EEG are characteristic signatures of epilepsy. These potentials originate as a result of synchronous pathological discharge of many neurons. The reliable detection of such potentials has been the long standing problem in EEG analysis, especially after long-term monitoring became common in investigation of epileptic patients. The traditional definition ...
متن کاملIs it time to replace epileptic spikes with fast ripples?
Is it time to replace epileptic spikes with fast ripples? In well over a century of performing epilepsy surgery, only 60%–65% of patients are, on average, seizure-free postoperatively. 1 Despite multiple advances in neuroimaging and electrophysiologic techniques for localizing the epileptogenic zone and determining its boundaries, defining the exact amount of neuronal tissue required to resect ...
متن کاملApplication of a hemodynamic model to epileptic spikes
Despite the interest in simultaneous EEG-fMRI studies of epileptic spikes, the link between epileptic discharges and their corresponding hemodynamic responses is poorly understood. We applied two biophysical models in order to investigate the mechanisms underlying the neurovascular coupling in epilepsy: a metabolic hemodynamic model, and a neural mass model that simulates epileptic discharges. ...
