Reliability and precision of the mouse calyx of Held synapse.

2 Nov 2009 Traditionally, the calyx of Held synapse is viewed as a highly reliable relay in the sound localization circuit of the auditory brainstem, with every presynaptic action potential triggering a postsynaptic action potential in vivo. However, this view ...

Management of pediatric brainstem cavernous malformations: experience over 20 years at the hospital for sick children.

30 Oct 2009 OBJECT: Because of their location and biological behavior, brainstem cavernous malformations (CMs) pose a formidable clinical challenge to the neurosurgeon. The optimal management of these lesions requires considerable neurosurgical judgment. ...

ABC Surgical Risk Scale for skull base meningioma: a new scoring system for predicting the extent of tumor removal and neurological outcome. Clinical article.

30 Oct 2009 OBJECT: Surgery for skull base meningiomas (SBMs) can lead to complications because these lesions are difficult to approach and can involve cranial nerves and arteries. The authors propose a scoring system to evaluate the relative risks and benefits ...

Regulation of trigeminal respiratory motor activity in the brainstem.

30 Oct 2009 The trigeminal motor system participates in the control of respiration as well as suckling and mastication. However, the central mechanism underlying respiratory activity in trigeminal motoneurons is not well-understood. In this study, we aimed to ...

Adaptive replanning strategies accounting for shrinkage in head and neck IMRT.

30 Oct 2009 PURPOSE: Significant anatomic and volumetric changes occur in head and neck cancer patients during fractionated radiotherapy, and the actual dose can be considerably different from the original plan. The purposes of this study were (1) to evaluate ...

Neural correlates of consonance, dissonance, and the hierarchy of musical pitch in the human brainstem.

19 Oct 2009 Consonant and dissonant pitch relationships in music provide the foundation of melody and harmony, the building blocks of Western tonal music. We hypothesized that phase-locked neural activity within the brainstem may preserve information relevant ...

Brainstem 1H nuclear magnetic resonance (NMR) spectroscopy: marker of demyelination and repair in spinal cord.

29 Sep 2009 Measuring in vivo spinal cord injury and repair remains elusive. Using magnetic resonance spectroscopy (MRS) we examined brainstem N-acetyl-aspartate (NAA) as a surrogate for spinal cord injury in two mouse strains with different reparative ...

A dynamic causal model of the coupling between pulse stimulation and neural activity.

29 Sep 2009 We present a dynamic causal model that can explain context-dependent changes in neural responses, in the rat barrel cortex, to an electrical whisker stimulation at different frequencies. Neural responses were measured in terms of local field ...

The neuronal control of hypoxic ventilation: erythropoietin and sexual dimorphism.

29 Sep 2009 Using mice, we demonstrated that when oxygen supply is lowered, erythropoietin (Epo), the main regulator of red blood cell production, modulates the ventilatory response by interacting with central (brainstem) and peripheral (carotid bodies) ...

Pediatric thalamic glioblastoma associated with Ollier disease (multiple enchondromatosis): a rare case of concurrence.

29 Sep 2009 Ollier disease and Maffucci syndrome are rare syndromes in which there is deforming dysplasia of cartilage, primarily but not exclusively involving the metaphyses and diaphyses of long bones. In a minority of patients, dysplasia can lead to ...
