Influence of dual-task constraints on the interaction between posture and movement during a lower limb pointing task
(2018-04-01)
One of the challenges regarding human motor control is making the movement fluid and at a limited cognitive cost. The coordination between posture and movement is a necessary requirement to perform daily life tasks. The ...
Delay discounting: concepts and measures
(Pontifícia Universidade Católica do Rio de Janeiro (PUC-Rio)Universidade de Brasília (UnB)Universidade de São Paulo (USP), 2012-12-01)
Delay discounting, one element which underlies decision-making, can be defined as the depreciation of the value of a reward related to the time that it takes to be released. High rates of delay discounting are found in ...
Optimization of postural control in precise gaze shifts and laser pointing
(2021-10-01)
Young adults are known to reduce their postural sway to perform precise visual search and laser pointing tasks. We tested if young adults could reduce even more postural and/or center of pressure sway to succeed in both ...
Dual task interferes with sensorimotor coupling in postural control
(2014-06-01)
Although the effects of cognitive tasks on postural control have been widely investigated, the influence of cognitive load on sensorimotor coupling in postural control is still being uncovered. The purpose of the present ...
Monitoring multiple cortical regions during walking in young and older adults: Dual-task response and comparison challenges
(2019-01-01)
Performance of several tasks simultaneously (dual-tasks) is common in everyday walking. Studies indicate that dual-task walking performance declines with age together with cognitive function, but neural mechanisms underpinning ...
Behavioral synergic relations between eye and postural movements in young adults searching to locate objects in room inside houses
(2022-02-01)
During precise gaze shifts, eye, head, and body movements exhibit synergic relations. In the present study, we tested the existence of behavioural synergic relations between eye and postural movements in a goal-directed, ...
Colony dehydration and water collection by specialized caste in the leaf-cutting ant Atta sexdens rubropilosa
(SPRINGER/PLENUM PUBLISHERS, 2008)
Social organization enables leaf-cutting ants to keep appropriate micro-ecological nest conditions for the fungus garden (their main food), eggs, larvae and adults. To maintain stability while facing changing conditions, ...
Dual task and postural control in Alzheimer's and Parkinson's disease
(Universidade Estadual Paulista, 2014)
Patients with neurodegenerative diseases are required to use cognitive resources while maintaining postural control. The aim of this study was to investigate the effects of a frontal cognitive task on postural control in ...
Unsupervised selective rank fusion for image retrieval tasks
(2020-02-15)
Several visual features have been developed for content-based image retrieval in the last decades, including global, local and deep learning-based approaches. However, despite the huge advances in features development and ...
