Brain stimulation reveals critical auditory naming cortex.
One challenge in dominant temporal lobe epilepsy surgery is to remove sufficient epileptogenic tissue without compromising post-operative language functioning. Pre-resection electrical stimulation mapping enables identification of language areas that can be spared from resection, and also provides a unique opportunity to investigate brain-language relationships. Visual object naming is the gold...
متن کاملRestoring cerebral blood flow reveals neural regions critical for naming.
We identified areas of the brain that are critical for naming pictures of objects, using a new methodology for testing which components of a network of brain regions are essential for that task. We identified areas of hypoperfusion and structural damage with magnetic resonance perfusion- and diffusion-weighted imaging immediately after stroke in 87 individuals with impaired picture naming. Thes...
متن کاملDeep Brain Stimulation Reveals Emotional Impact Processing in Ventromedial Prefrontal Cortex
We tested the hypothesis that modulation of monoaminergic tone with deep-brain stimulation (DBS) of subthalamic nucleus would reveal a site of reactivity in the ventromedial prefrontal cortex that we previously identified by modulating serotonergic and noradrenergic mechanisms by blocking serotonin-noradrenaline reuptake sites. We tested the hypothesis in patients with Parkinson's disease in wh...
متن کاملFunctional Imaging Reveals Numerous Fields in the Monkey Auditory Cortex
Anatomical studies propose that the primate auditory cortex contains more fields than have actually been functionally confirmed or described. Spatially resolved functional magnetic resonance imaging (fMRI) with carefully designed acoustical stimulation could be ideally suited to extend our understanding of the processing within these fields. However, after numerous experiments in humans, many a...
متن کاملHearing suppression induced by electrical stimulation of human auditory cortex.
In the course of performing electrical stimulation functional mapping (ESFM) in neurosurgery patients, we identified three subjects who experienced hearing suppression during stimulation of sites within the superior temporal gyrus (STG). One of these patients had long standing tinnitus that affected both ears. In all subjects, auditory event related potentials (ERPs) were recorded from chronica...
