Benign Epilepsy with Centro-temporal Spikes: Spike Triggered fMRI Shows Somato-sensory Cortex Activity

Summary:  Objective: We performed spike triggered functional MRI (fMRI) in a 12 year old girl with Benign Epilepsy with Centro-temporal Spikes (BECTS) and left-sided spikes. Our aim was to demonstrate the cerebral origin of her interictal spikes. Methods: EEG was recorded within the 3 Tesla MRI. Whole brain fMRI images were acquired, beginning 2–3 seconds after spikes. Baseline fMRI images were acquired when there were no spikes for 20 seconds. Image sets were compared with the Student's t-test. Results: Ten spike and 20 baseline brain volumes were analysed. Focal activiation was seen in the inferior left sensorimotor cortex near the face area. The anterior cingulate was more active during baseline than spikes. Conclusions: Left sided epileptiform activity in this patient with BECTS is associated with fMRI activation in the left face region of the somatosensory cortex, which would be consistent with the facial sensorimotor involvement in BECT seizures. The presence of BOLD signal change in other regions raises the possibility that the scalp recorded field of this patient with BECTs may reflect electrical change in more than one brain region.

Give way to great charms of Halifax, Nova Scotia, Canada

A travel article about Halifax, Nova Scotia. MOTORISTS in Nova Scotia are so polite it's almost a shame to leave, writes Kari Gislason. By the end of my second day in Halifax, I begin to develop deep concerns about the safety of the locals, or the Haligonians as they're known. I wonder how they ever leave their fair city or, perhaps more to the point, how they ever make it back...

Experience the sights & sounds of Cape Breton, Nova Scotia

A travel article about Nova Scotia, and the area's annual Celtic music festival. I ARRIVED in Cape Breton on the occasion of the Fibre Festival, run not only by the South Haven Guild of Weavers but also the Baddeck Quilters Guild. And yet I might not have noticed that it was on, had it not been for a car, shrouded entirely by a quilt cover, that was parked outside the Volunteer Fire Department Hall. I was on my way to the Alexander Graham Bell Museum a little further along Baddeck's main street. But I stopped, for who wouldn't stop to look at the various fibres of Cape Breton. The hall had been divided between weavers and quilters. Naturally, I left hoping that one day this ancient divide might be healed...

Follow the lighthouse route in Nova Scotia, Canada

Within half an hour of leaving Halifax Airport I managed to get myself lost. I noticed an exit sign for St Margaret’s Bay and, despite written instructions to the contrary, it sounded like the right way to go. But I was on the Lighthouse Route and on my way back to Halifax...
