Age-related changes in oscillatory power affect motor action
With increasing age cognitive performance slows down. This includes cognitive processes essential for motor performance. Additionally, performance of motor tasks becomes less accurate. The objective of the present study was to identify general neural correlates underlying age-related behavioral slowing and the reduction in motor task accuracy. To this end, we continuously recorded EEG activity ...
متن کاملA histomorphometric study on age-related changes in selected lymphoid structures of Chukar partridge (Alectoris chukar)
Background: Chukar partridge (Alectoris chukar) is raised for its highly nutritional and relatively expensive meat. Aims: This study evaluates selected lymphoid organs of juvenile and peripubertal Chukar partridges using a histomorphometric approach. Methods: Thirty one-day-old male and female Chukar partridges were included in the stu...
متن کاملAge-related hemispheric asymmetry in object discrimination.
Young and elderly observers judged whether two sequentially presented images in either the left or right visual field (LVF or RVF) were the same or different. The two objects depicted were always from the same entry-level category, but could differ only in viewpoint (a "same" trial--observers were instructed to ignore viewpoint changes) and/or in exemplar (a "different" trial). Young observers ...
متن کاملAge-related Changes in Lateral Entorhinal and CA3 Neuron Allocation Predict Poor Performance on Object Discrimination
Age-related memory deficits correlate with dysfunction in the CA3 subregion of the hippocampus, which includes both hyperactivity and overly rigid activity patterns. While changes in intrinsic membrane currents and interneuron alterations are involved in this process, it is not known whether alterations in afferent input to CA3 also contribute. Neurons in layer II of the lateral entorhinal cort...
متن کاملDiagnostic sensitivity and specificity of dark adaptometry for detection of age-related macular degeneration.
PURPOSE Difficulty with night vision is a common complaint of patients with age-related macular degeneration (AMD). Consistent with this complaint, dark adaptation (DA) is substantially impaired in these patients. Because of the severity of the deficit, measurement of DA has been suggested as a means for the diagnosis of AMD. Previous methods for measurement of DA were time intensive (>30 minut...
