Electrocorticographic 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 کاملFunctional mapping of human sensorimotor cortex with electrocorticographic spectral analysis. II. Event-related synchronization in the gamma band.
It has been shown in animals that neuronal activity in the 'gamma band' (>30 Hz) is associated with cortical activation and may play a role in multi-regional and multi-modal integration of cortical processing. Studies of gamma activity in human scalp EEG have typically focused on event-related synchronization (ERS) in the 40 Hz band. To assess further the gamma band ERS further, as an index of ...
متن کاملFunctional mapping of human sensorimotor cortex with electrocorticographic spectral analysis. I. Alpha and beta event-related desynchronization.
Human scalp EEG studies have shown that event-related desynchronization (ERD) in the alpha (8-13 Hz) and beta (15-25 Hz) bands may be used to detect functional activation of sensorimotor cortex. However, in most previous studies somatotopy has not been examined in detail and brief, self-paced movements, focusing on the planning of motor output, have been used. We recorded electrocorticographic ...
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 کاملElectrocorticographic activity over sensorimotor cortex and motor function in awake behaving rats.
Sensorimotor cortex exerts both short-term and long-term control over the spinal reflex pathways that serve motor behaviors. Better understanding of this control could offer new possibilities for restoring function after central nervous system trauma or disease. We examined the impact of ongoing sensorimotor cortex (SMC) activity on the largely monosynaptic pathway of the H-reflex, the electric...
