Experimental determination of human peripheral nerve stimulation thresholds in a 3-axis planar gradient system.

30 Aug 2009 In MRI, strong, rapidly switched gradient fields are desirable because they can be used to reduce imaging time, obtain images with better resolution, or improve image signal-to-noise ratios. Improvements in gradient strength can be made by either ... Read more...

Stimulus-dependent correlations in threshold-crossing spiking neurons.

30 Jul 2009 We consider a threshold-crossing spiking process as a simple model for the activity within a population of neurons. Assuming that these neurons are driven by a common fluctuating input with gaussian statistics, we evaluate the cross-correlation of ... Read more...

Comparison between odor thresholds for phenyl ethyl alcohol and butanol.

29 Jun 2009 Aim of the study was to compare results of odor threshold test using different numbers of dilution steps, separately for butanol and phenyl ethyl alcohol (PEA). METHODS: A total of 116 subjects participated (29 patients with olfactory dysfunction ... Read more...
