Developmental instability (DI) is the sensitivity of a developing trait to random noise and can be measured by degrees of directionally random asymmetry [fluctuating asymmetry (FA)]. FA has been shown to increase with loss of genetic variation and inbreeding as measures of genetic stress, but associations vary among studies. Directional selection and(More)
Patient-reported stimulus-related radiating sensory symptoms within the territory of the stimulated nerve have been used to verify stimulation in sensory nerve scalp recorded somatosensory evoked potentials (SEP). The main aim of the present study of false positive P1 latency prolongation in lumbosacral sensory nerve SEP was to investigate whether(More)
Biogeosciences Discussions This discussion paper is/has been under review for the journal Biogeosciences (BG). Please refer to the corresponding final paper in BG if available. Abstract Alongside a primary productivity gradient between the Galicia Bank region in the northeast Atlantic and the more oligotrophic eastern Mediterranean basin, we investigated(More)
The diagnostic utility of scalp-recorded somatosensory evoked potentials (SEP) in patients with sciatica has generally been regarded as low. The purpose of the present study was to determine the validity of sensory nerve SEP in different subgroups of sciatic patients. A total of 65 consecutive patients with sciatica showing disc pathology and/or facet joint(More)
The aim of the present study was to evaluate the ability of sensory nerve somatosensory evoked potentials (SEP) to discriminate between lumbar spine computed tomography (CT) findings with and without relevance for the radiating sensory symptoms in patients with sciatica in whom myelography does not have such discriminatory capacity. Forty consecutive(More)
The purpose of the present study was to establish a method that allows the general use of subject-based criteria to evaluate P1 latency in scalp recorded somatosensory evoked potentials obtained with stimulation of the sural (S1), superficial peroneal (L5) and saphenous (L4) nerves bilaterally. The nerves were stimulated at the same distance from the(More)
