The following two new research reports published in Epilepsia journal [quoted Epilepsy current]might be of interest to those Epilepsy doctors and professionals, ofcourse to Neurophysiologists and long term intraoperative monitoring field.

Are HFOs Still UFOs? The Known and Unknown About High Frequency Oscillations in Epilepsy Surgery

High-Frequency Oscillations, Extent of Surgical Resection, and Surgical Outcome in Drug-Resistant Focal Epilepsy.

Epilepsia 2013;54:848–857.

PURPOSE: Removal of areas generating high-frequency oscillations (HFOs) recorded from the intracerebral electroencephalography
(iEEG) of patients with medically intractable epilepsy has been found to be correlated with improved surgical outcome. However, whether differences exist according to the type of epilepsy is largely unknown. We performed a comparative assessment of the impact of removing HFO-generating tissue on surgical outcome between temporal lobe epilepsy (TLE) and extratemporal lobe epilepsy (ETLE). We also assessed the relationship between the extent of surgical resectionand surgical outcome.

Ripple Classification Helps to Localize the Seizure-Onset Zone in Neocortical Epilepsy.

Wang S, Wang IZ, Bulacio JC, Mosher JC, Gonzalez-Martinez J, Alexopoulos AV, Najm IM, So NK.

 Epilepsia 2013;54:370–376.

PURPOSE: Fast ripples are reported to be highly localizing to the epileptogenic or seizure-onset zone (SOZ) but may not be readily found in neocortical epilepsy, whereas ripples are insufficiently localizing. Herein we classified interictal neocortical ripples by associated characteristics to identify a subtype that may help to localize the SOZ in neocortical epilepsy. We hypothesize that ripples associated with an interictal epileptiform discharge (IED) are more pathologic,since the IED is not a normal physiologic event.

Neuron News:-

Neuron news is a WebRing site that publishes some cool topics in neuroscience, in this Nov 2008 news note, they talk about EcoG and developments in this neurotechnology?. I do not find anything new in this news as EcoG is already recorded in clinical set up, but the one thing that is interesting in this news is the type of electrode development, something that can sit on the surface of the brain without perturbations of membranes or causing any penetration that would be deleterious, anyways, there are lots of stuff to browse through including a lot on consiousness at neuronews.
