To investigate the effects of central sensitization, elicited by intramuscular injection of capsaicin, by comparing the reflex receptive fields (RRF) of spinally-intact volunteers and spinal cord injured volunteers that present presensitized spinal nociceptive mechanisms. ⋯ Protective plastic mechanisms may still be functional in SCI volunteers.
-
The aim of the present study was to assess whether peripheral mechanisms, mediated through axonal dysfunction, may contribute to development of the split-hand in amyotrophic lateral sclerosis (ALS). ⋯ Axonal dysfunction may appear as a downstream process that develops secondary to the intrinsic pathophysiological origins of ALS.

Occipital electroencephalogram (EEG) activity is known to be different from the frontal EEG during wakefulness and anesthesia. However, less is known about occipital non-linear dynamics analyzed by EEG-bicoherence, which can reflect the oscillatory features that are dependent on thalamocortical modulation. ⋯ Nonlinear regulation of the occipital EEG is different from the frontal EEG during every stage of anesthesia.

The few published ultrasound (US) studies on chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) report diffusely increased cross-sectional area (CSA) of nerves. The data are, however, heterogeneous and correlations with clinical history or disease severity are lacking. ⋯ These results offer the possibility of exploring the use of US to assess CIDP disease activity and treatment.

To describe the causes and outcome of adult patients with preserved electroencephalographic activity despite clinical findings suggesting brain death (BD), and its impact on organ donation. ⋯ The use of EEG can decrease the time interval for brain death diagnosis.
