The perception of a visual stimulus can be inhibited by occipital transcranial magnetic stimulation. This visual suppression effect has been attributed to disruption in the cortical gray matter of primary visual cortex or in the fiber tracts leading to V1 from the thalamus. However, others have suggested that the visual suppression effect is caused by(More)
We have combined three-dimensional (3D) computer-reconstructed neuroimages with a novel video registration technique for virtual reality-based, image-guided surgery of the brain and spine. This technique allows the surgeon to localize cerebral and spinal lesions by superimposing a 3D-reconstructed MR or CT scan on a live video image of the patient. Once the(More)
We describe functional brain mapping experiments using a transcranial magnetic stimulation (TMS) device. This device, when placed on a subject's scalp, stimulates the underlying neurons by generating focused magnetic field pulses. A brain mapping is then generated by measuring responses of different motor and sensory functions to this stimulation. The key(More)
If sales figures are any indication, Christians have been eager to purchase and promote the reports of those who claim to have been to Heaven and returned to tell us about it. 90 Minutes In Heaven and Heaven Is For Real have proven to be wildly popular in Christian circles. 1 This gullible lack of discernment presents us with an interesting dilemma: what do(More)
Localization of tumors in brain surgery is one of the most challenging aspects of the field. The poor tolerance of surrounding normal tissue to disruption necessitates accurate and precise targeting. In difficult cases involving small or deep tumors localization has traditionally been achieved using a stereolactic frame rigidly fixed to the patient's skull.(More)
