Laterality is an important feature of motor behavior. Several studies have shown that lateralization in right-handed young adults (i.e., right versus left arm superiority) emerges also during imagined actions, that is when an action is internally simulated without any motor output. Such information, however, is lacking for elderly people and it could be valuable to further comprehend the evolut...

The production and application of nano-/micromotors is of great importance. In order for the motors to work, asymmetry in their chemical composition or physical geometry must be present if no external asymmetric field is applied. In this paper, we present a "coconut" micromotor made of platinum through the partial or complete etching of the silica templates. It was shown that although both the ...

BACKGROUND Dopamine neurotransmission plays a key role in several brain activities, including motor, cognitive, and behavioral functions. Parkinson's disease (PD) typically begins with asymmetrical motor features related to asymmetrical dopamine denervation. This study was designed to examine whether distinct cognitive, behavioral, and personality features are related to this asymmetry. METHO...

The onset and progression of Parkinson's disease (PD) motor symptoms is generally asymmetric, reflecting differential extent of nigral pathology and resulting dopamine depletion in each of the hemispheres. Given the role of dopamine in processing rewarding and aversive events, and considering findings associating asymmetric neural activity with differential sensitivity to positive and negative ...

OBJECTIVE Several studies have investigated asymmetry and loading patterns in different spine pathologies, motor disorders, and other conditions; there is a lack of knowledge on these aspects in chronic low back pain (CLBP). The aim of this study was to analyse asymmetry and loading patterns in patients with nonspecific chronic low back pain (NCLBP) compared to normal individuals, during walkin...

introduction: animal models of parkinson’s disease (pd) with partial damage of nigrostriatal dopaminergic system are very suitable for development of treatment strategies. although drug-induced rotational behavior has been conventionally used for analysis of lesioned animals, but bcause of the development of sensitization, it is necessary to invent a pure behavioral test that can evaluate such ...

to the left due to paresis of the left pterygoid muscle. The corneal refl ex was positive on both sides. All other neurological systems were regular. In particular, there were no sensory disturbances and no signs of polyneuropathy. Electromyography did not detect pathological spontaneous activity (most probably due to massive atrophy and chronicity of the process), but showed a single unit inte...
