Somatosensory evoked potentials during mild hypothermia after cardiopulmonary resuscitation.

Nov 2009 OBJECTIVE: In patients who remain in a coma after cardiopulmonary resuscitation (CPR), the bilateral absence of cortical N20 responses of median nerve somatosensory evoked potentials (SSEP) 24 hours after admission invariably correlates with a poor ... Read more...

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 ... Read more...

Misleading functional magnetic resonance imaging mapping of the cortical hand representation in a 4-year-old boy with an arteriovenous malformation of the central region.

29 Sep 2009 Functional MR imaging is dependent on the hemodynamic response function of the brain. Cerebrovascular anomalies may lead to hemodynamic artifacts, contorting the true localization of neural activation. This is illustrated in the case of a 4-year-old ... Read more...
