Insular and Amygdala Origin Seizures: Unmasked with Electrocorticography (ECOG)
Introduction:
Insula and amygdala have a large network of connections to other cortical regions. Seizures originating from these structures may become evident only after propagation to other structures. High degree of attention must be paid to auras and seizure semiology in patients with medically intractable epilepsy.
Methodology:
We have described a series of three adult male patients with focal intractable epilepsy who did not have structural lesions on Magnetic Resonance Imaging (MRI). Patients underwent MRI, Positron Emission Tomography (PET) scan, scalp electroencephalography (EEG), and stereo EEG implantation.
Results:
All three patients …

Medical Student Research Symposium
Introduction: Cellular reaction to traumatic brain injury is complex and involves considerable interactions between cells and reactivity to foreign bodies. Our objective was to assess neurons, microglia, astrocytes, and intracellular Ca2+ signaling by creating a novel confocal microscopy technique involving an air immersed lens that does not sacrifice resolution and limits signal attenuation. This study aimed to create a consistent dynamic methodology to observe the cortical cellular response using real-time intravital imaging as trauma is being induced.
Methods: Once surgical plane was achieved, rodent cortices were exposed via craniotomy and blunt insertion with a silicone shunt catheter into the …
