Tests of postural rotational laterality were carried out in 63 patients suffering from torticollis (53) or torsion dystonia with torticollis (10) and in 33 normal subjects. There was a correlation between the predominant direction of postural functions and the direction of the rotatory component of torticollis. Torticollis and torsion dystonia may be due to the release of a postural rotational ...
In the teleost fish Girardinus falcatus eye preferences for inspecting a potential predator is highly heritable and this consented to select lines with opposed laterality. In previous studies individuals from a RD line (rightward turning when facing a dummy predator) and those from a LD line (leftward turning) were subjected to several other laterality tests (most of which, possibly all, were v...
The mechanisms that establish behavioral, cognitive, and neuroanatomical asymmetries are poorly understood. In this study, we analyze the events that regulate development of asymmetric nuclei in the dorsal forebrain. The unilateral parapineal organ has a bilateral origin, and some parapineal precursors migrate across the midline to form this left-sided nucleus. The parapineal subsequently inner...
We studied detour responses of two species of poeciliid fish (Gambusia hoolbroki and Girardinus falcatus) faced with a vertical-bar barrier, through which conspecifics of the same or different sex or a simulated-predator (which induced detour behaviour for predator-inspection responses) were visible. Both species showed a consistent bias to turn leftward when faced with the predator, and a cons...
Ocklenburg et al. (2020, Laterality 2020: Entering the next decade. Laterality) provided field of laterality research with a stimulating perspective for coming decade, based on current state art in both animal and human research. Although this is paper takes many different approaches into account, we emphasize that eco-evolutionary approach needs more attention. This concerns question why organ...
Objectives: The present study aimed to investigate the possible effects of laterality and handedness on higher-order sensory functions and manual dexterity of the elderly. Methods: In this non-experimental cross-sectional study, 58 elderly people aged 60-75 years (35 right-handed) were recruited through a convenience sampling method. Laterality of the selected subjects was examined using the E...
OBJECTIVE To investigate swallowing laterality in hemiplegic patients with stroke and recovery of dysphagia according to the laterality. METHOD The sample was comprised of 46 dysphagic patients with hemiplegia after their first stroke. The sample's videofluoroscopic swallowing study (VFSS) was reviewed. Swallowing laterality was determined by the anterior-posterior view of VFSS. We measured w...
