Electrocorticographic Temporal Alteration Mapping: A Clinical Technique for Mapping the Motor Cortex with Movement-Related Cortical Potentials
We propose electrocorticographic temporal alteration mapping (ETAM) for motor cortex mapping by utilizing movement-related cortical potentials (MRCPs) within the low-frequency band [0.05-3] Hz. This MRCP waveform-based temporal domain approach was compared with the state-of-the-art electrocorticographic frequency alteration mapping (EFAM), which is based on frequency spectrum dynamics. Five pat...
متن کاملElectrocorticographic Frequency Alteration Mapping: a Clinical Technique
Received, May 25, 2006. Accepted, November 10, 2006. Creating transient lesions or inducing overt movements through the use of direct electrocortical stimulation (ECS), either extraor intraoperatively, has been an established practice in delineating eloquent cortex (3, 5, 26). This has been critical in minimizing the risk in neurological surgeries that involve seizure focus, tumor, or vascular ...
متن کاملElectrocorticographic frequency alteration mapping for extraoperative localization of speech cortex.
OBJECTIVE Electrocortical stimulation (ECS) has long been established for delineating eloquent cortex in extraoperative mapping. However, ECS is still coarse and inefficient in delineating regions of functional cortex and can be hampered by afterdischarges. Given these constraints, an adjunct approach to defining motor cortex is the use of electrocorticographic (ECoG) signal changes associated ...
متن کاملMapping phantom movement representations in the motor cortex of amputees.
Limb amputation results in plasticity of connections between the brain and muscles, with the cortical motor representation of the missing limb seemingly shrinking, to the presumed benefit of remaining body parts that have cortical representations adjacent to the now-missing limb. Surprisingly, the corresponding perceptual representation does not suffer a similar fate but instead persists as a p...
متن کاملSensory motor cortex: correlation of presurgical mapping with functional MR imaging and invasive cortical mapping.
PURPOSE To describe a clinically useful application of functional magnetic resonance (MR) imaging--presurgical mapping of the sensory motor cortex--and to validate the results with established physiologic techniques. MATERIALS AND METHODS Functional MR mapping of the sensory motor cortex was performed in two women, aged 24 and 38 years. Both had intractable, simple partial motor seizures due ...
