13. Cognition and cerebral blood flow in lateralised parkinsonism: lack of functional lateral asymmetries.
Cognitive and cerebral blood flow (CBF) lateral asymmetries have been quantified in 23 right handed patients with lateralised idiopathic Parkinson's disease. Thirteen patients who had predominant right-sided symptoms (RPD) were compared with ten who had predominant left-sided symptoms (LPD). The patient subgroups were matched for age, education, duration of

14. Lateralisation of cortical function during cognitive tasks: regional cerebral blood flow studies of normal individuals and patients with schizophrenia.
To assess cognitively-related regional asymmetries of brain function, regional cerebral blood flow (rCBF) was determined by the xenon inhalation method while normal subjects performed 10 different tasks and also while they were at rest. In addition to healthy subjects, patients with schizophrenia were also studied. A total of 447 rCBF studies were carried ou

15. Gesture Subtype–Dependent Left Lateralization of Praxis Planning: An Event-Related fMRI Study
Ideomotor apraxia is a disorder mainly of praxis planning, and the deficit is typically more evident in pantomiming transitive (tool related) than intransitive (communicative) gestures. The goal of the present study was to assess differential hemispheric lateralization of praxis production using event-related functional magnetic resonance imaging. Voxel-base

16. Side-Specificity of Olfactory Learning in the Honeybee: Generalization between Odors and Sides
Honeybees (Apis mellifera) can be trained to associate an odor stimulus with a sucrose reward. The neural structures involved in the detection and integration of olfactory stimuli are represented bilaterally in the brain. Little is known about the respective roles of the two sides of the brain in olfactory learning. Does each side learn independently of the

17. Lateralization of expression of neural sympathetic activity to the vessels and effects of carotid baroreceptor stimulation
Human studies suggest that cardiovascular neural sympathetic control is predominantly modulated by the right cerebral hemisphere. It is unknown whether post-ganglionic sympathetic activity [muscle sympathetic nerve activity (MSNA)] shows any functional asymmetry. Eight right-handed volunteers (3 women and 5 men, 32 ± 2 yr of age) underwent ECG, beat-by-beat
