Temporal Dynamics of Motor Functioning and Cognitive Aging

Motor and cognitive changes in normal aging

In a recent study, Cid-Fernandez et al. (2014) tested attentional performance in 3 age groups: young (21–29 years old), middle-aged (51–64 years old), and older adults (65–84 years old). The task used in this study involved presenting both visual and auditory cues to the participants, and they were required to pay attention to the visual cues while ignoring the auditory cues (for task details, ...

Temporal Dynamics of Bacterial Aging and Rejuvenation

Single-celled organisms dividing by binary fission were thought not to age [1-4]. A 2005 study by Stewart et al. [5] reversed the dogma by demonstrating that Escherichia coli were susceptible to aging. A follow-up study by Wang et al. [6] countered those results by demonstrating that E. coli cells trapped in microfluidic devices are able to sustain robust growth without aging. The present study...

Cognitive and Cognitive-Motor Interventions Affecting Motor Functioning of Older Adults: A Systematic Review

Cognitive motor control: spatial and temporal aspects.

Cognitive motor control refers to processes that blend cognitive and motor functions in a seamless, interwoven fashion. Such functions evolve in space and time at various levels of complexity. This article focuses on conceptual issues regarding spatial and temporal aspects of motor control as well as on methods suitable for extracting information from neuronal ensembles.

Temporal Dynamics of Cognitive Control

Cognitive control refers to the flexible deployment of memory and attention in response to task demands and current goals. Control is often studied experimentally by presenting sequences of stimuli, some demanding a response, and others modulating the stimulus-response mapping. In these tasks, participants must maintain information about the current stimulus-response mapping in working memory. ...
