There have been several studies of the neural mechanisms underlying sensation of fatigue. However, little is known about the neural mechanisms underlying self-evaluation of the level of fatigue. The aim of this study was to identify the neural substrates involved in self-evaluation of the level of mental fatigue. We used magnetoencephalography (MEG) with high temporal resolution on 14 healthy p...

The Meaning-Text Theory is a formal, dependency-based linguistic theory in which the lexicon plays a central role. Within this theory, the vocabulary of a language is described by an Explanatory-Combinatorial Dictionary [ECD]. Unlike most existing dictionaries, an ECD is oriented towards language generation rather than analysis. This orientation makes it especially useful for language learners ...

AIM To perform genealogical and clinical studies in Finnish families with X linked ocular albinism (OA1), including characterisation of the potential misrouting of optic fibres by evaluating visual evoked magnetic fields (VEFs), and to determine the mutation behind the disease. METHODS Three families with OA1 were clinically examined. VEFs were measured in two affected males and in one female...

1. Introduction The cerebral representation of pain perception in humans is poorly understood compared with that of other sensations such as touch or vibration. This is mainly because of a lack of appropriate instrumentation for stimulation and recording [1]. To our knowledge, only a few systematic studies of somatosensory evoked magnetic field (SEF) following painful stimulation (pain-related ...

Analysis of catecholamines (epinephrine, norepinephrine and dopamine) in plasma and urine is used for diagnosis and treatment of catecholamine-producing tumors. Current analytical techniques for catecholamine quantification are laborious, time-consuming and technically demanding. Our aim was to develop an automated on-line solid phase extraction method coupled to high performance liquid chromat...
