Too many schools still donвЂ™t seem to know about the benefits of encouraging pupils to be confident speakers, or havenвЂ™t integrated oracy into other parts of the curriculum. This week sees the launch of a campaign, the Oracy Network, to raise the profile of public speaking in the national curriculum, backed by the English Speaking Union (ESU) and involving, among others, Peter Hyman, founder of School 21 in east London and an enthusiast for the cause. However, this conclusion was relatively ungrounded due to the lack of extensive neuropsychological testing in homogenous patient groups.Robinson, who advises Highbury Grove, says: вЂњIt is important that young people develop educated opinions, that is, opinions that emerge after exploring and weighing up different sides of an argument.вЂќ Robinson believes an educated 18-year-old вЂњshould be able to respond to gentle interrogation and not worry when they get to the point of not knowing, relish it even because they can explore and find out moreвЂќ. Several studies claimed that surgery in eloquent areas is possible without causing severe cognitive decline. Not extensive surgery or tumor size but surgery at eloquent locations impacts complication occurrence the strongest with a 2 fold increased complication occurrence risk Since functional magnetic resonance imaging and intraoperative neurophysiological mapping are not available in all neurosurgical departmentsД®loquent tumor location proved as significant risk factors for encountering a therapy associated complication. Much higher spatial and temporal resolution maps of cortical activity can be achieved with a technique called electrocorticography, however this requires placement of subdural electrodes on the surface of the brain and this must be done during surgery.

Through tailored pre- and intraoperative mapping and monitoring the EOR can be maximized, with reduced rates of surgery-related deficits. Intraoperative monitoring with direct cortical stimulation and subcortical stimulation enables surgeons to preserve essential functional tissue during surgery. Imaging techniques such as functional MRI and diffusion tensor imaging fiber tracking, and neurophysiological methods like navigated transcranial magnetic stimulation and magnetoencephalography, make it possible to identify eloquent areas prior to resective surgery and to tailor indication and surgical approach but also to assess the surgical risk.

Neuroimaging techniques such as magnetic resonance imaging, electroencephalography, or magnetoencephalography are especially useful non-invasive tools to locate eloquent cortex. Intraoperative confirmation is done with CS and N20 inversion wave for cortical structures and with sCS for subcortical pathways Cortical motor functional areas are anatomically and functionally located preoperatively thanks to MR and functional magnetic resonance imaging and subcortical motor pathways with DT imaging and tractography. Multimodal navigation allows integration and correlation among preoperative and intraoperative anatomical and functional data. The integration of anatomical and functional studies allows a safe functional resection of the brain tumors located in eloquent areas. Grade I lesions are located in noneloquent brain To avoid permanent neurologic deficits and preserve brain function in and near the eloquent area, intraoperative electrical stimulation mapping (IESM) is necessary.Д®loquent locations in the Sawaya study are the motor/sensory cortices, visual center, speech center, internal capsule, basal ganglia, hypothalamus/thalamus, brainstem, and dentate nucleus The most common areas of eloquent cortex are in the left temporal lobe and frontal lobes for speech and language, bilateral occipital lobes for vision, bilateral parietal lobes for sensation, and bilateral motor cortex for movement. See pyramidal tract, optic radiation and arcuate fasciculus Name for areas of cortex that-if removed-will result in loss of sensory processing or linguistic ability, minor paralysis, or paralysis.
