Cognitive decline is a characteristic feature of normal human aging. Previous work has
demonstrated marked interindividual variability in onset and rate of decline. Such variability …

Simple reaction time (SRT), the minimal time needed to respond to a stimulus, is a basic
measure of processing speed. SRTs were first measured by Francis Galton in the 19th …

Aging is associated with delayed processing in choice reaction time (CRT) tasks, but the
processing stages most impacted by aging have not been clearly identified. Here, we …

In verbal fluency (VF) tests, subjects articulate words in a specified category during a short
test period (typically 60 s). Verbal fluency tests are widely used to study language …

Muscle motor-evoked potentials are commonly monitored during brain tumour surgery in
motor areas, as these are assumed to reflect the integrity of descending motor pathways …

A progressive decline in upper limb function is associated with ageing and disease. In this
cross-sectional study we assessed the performance of 367 healthy individuals aged of 20 to …

Temporal information processing (TIP) constitutes a complex construct that underlies many
cognitive functions and operates in a few hierarchically ordered time domains. This study …

Assessment of motor function is an essential part of most neuropsychological examinations
(Lezak, 2004; Strauss, Sherman, & Spreen, 2006). Early impairments of fine motor function …

Introduction Increased motor fatigability is a symptom of many neuromuscular and
neurodegenerative disorders. However, it is difficult to pinpoint pathological motor …

Although gamma aminobutyric acid (GABA) is of particular importance for efficient motor
functioning, very little is known about the relationship between regional GABA levels and …
