However, finer detail of the cortical organization of sign language is not readily available. Intraoperative ... Full text Link to item Cite

Intraventricular hemorrhage in blunt head trauma: an analysis of 43 cases.

Journal Article Neurosurgery · October 1992 Before the advent of computed tomography, intraventricular hemorrhage (IVH) from any source was thought rare and invariably fatal. Although intraventricular blood is readily identifiable with computed tomography, there has been little systematic study of i ... Full text Link to item Cite

Optical imaging of epileptiform and functional activity in human cerebral cortex.

Journal Article Nature · August 20, 1992 Optical imaging of animal somatosensory, olfactory and visual cortices has revealed maps of functional activity. In non-human primates, high-resolution maps of the visual cortex have been obtained using only an intrinsic reflection signal. Although the tim ... Full text Link to item Cite

Changes in gamma-aminobutyric acid and somatostatin in epileptic cortex associated with low-grade gliomas.

Journal Article J Neurosurg · August 1992 The role of specific neuronal populations in epileptic foci was studied by comparing epileptic and non-epileptic cortex removed from patients with low-grade gliomas. Epileptic and nearby (within 1 to 2 cm) non-epileptic temporal lobe neocortex was identifi ... Full text Link to item Cite

Resection of intrinsic tumors from nondominant face motor cortex using stimulation mapping: report of two cases.

Journal Article Surg Neurol · July 1991 We report two right-handed patients who underwent resection of intrinsic glial tumors from the nondominant hemisphere, face motor cortex. Both patients underwent preoperative assessment with computed tomography and magnetic resonance imaging localizing the ... Full text Link to item Cite

Symptomatic cerebral vasospasm following tumor resection: report of two cases.

Journal Article Surg Neurol · July 1991 The authors report two cases of symptomatic cerebral vasospasm following resection of an acoustic neuroma and a left sphenoid wing meningioma. Vascular spasm was documented by transcranial Doppler and angiography studies. Both patients responded to hypervo ... Full text Link to item Cite

Role of Na-K pump potassium regulation and IPSPs in seizures and spreading depression in immature rabbit hippocampal slices.

Journal Article J Neurophysiol · February 1990 1. Using the immature (8-12 days postnatal) rabbit hippocampal slice preparation, we investigated regional extracellular potassium concentration [( K+]o) changes that occur during spontaneous and evoked spreading depression (SD) episodes. We report here a ... Full text Link to item Cite

Neuronal activity in human lateral temporal cortex related to short-term verbal memory, naming and reading.

Journal Article Brain · December 1988 Extracellular microelectrode recordings were obtained from lateral temporal cortex that was subsequently resected in patients undergoing craniotomies under local anaesthesia for treatment of medically intractable epilepsy. During these recordings patients ... Full text Link to item Cite

Long-term efficacy of microvascular decompression in trigeminal neuralgia.

Journal Article J Neurosurg · July 1988 Forty patients were followed for an average period of 8 1/2 years after 44 consecutive suboccipital craniotomies for trigeminal neuralgia. Among these patients, 36 had microvascular decompression (MVD) of the nerve, four had repeat trigeminal rhizotomy aft ... Full text Link to item Cite

Spontaneous rhythmic synchronous activity in epileptic human and normal monkey temporal lobe.

Journal Article Epilepsia · 1986 Intracellular recordings were obtained from neurons in tissue taken from human epileptic temporal lobe and normal monkey hippocampus. Using the in vitro slice preparation, we confirmed that spontaneous rhythmic synchronous events (SRSEs) were predominantly ... Full text Link to item Cite

Developmental and regional differences in the localization of Na,K-ATPase activity in the rabbit hippocampus.

Journal Article Brain Res · September 16, 1985 Regional differences in Na,K-ATPase activity, and development of Na,K-ATPase activity were examined in rabbit hippocampus using a histochemical marker of enzyme activity. Stratum lucidum of CA3/CA2, corresponding to the mossy fiber terminal field, showed h ... Full text Link to item Cite

Seizure-like spreading depression in immature rabbit hippocampus in vitro.

Journal Article Brain Res · May 1984 Study of immature rabbit hippocampus, using the in vitro slice preparation, has revealed seizure-like spreading depression (SD) episodes in tissue from 8-12-day-old animals. These SDs occur both spontaneously and in response to stimulation, and are seen in ... Full text Link to item Cite
