Get a grip: individual variations in grip strength are a marker of brain health
TL;DR: It is now evident that while differences in grip strength between individuals are influenced by musculoskeletal factors, "lifespan" changes in grip Strength within individuals are exquisitely sensitive to integrity of neural systems that mediate the control of coordinated movement.

Defining sarcopenia: the impact of different diagnostic criteria on the prevalence of sarcopenia in a large middle aged cohort
Astrid Y. Bijlsma,Carel G. M. Meskers,Carolina H. Y. Ling,Marco V. Narici,Susan Kurrle,Ian D. Cameron,Rudi G. J. Westendorp,Andrea B. Maier +7 more
TL;DR: It is concluded that the prevalence of sarcopenia is highly dependent on the applied diagnostic criteria and it is necessary to reach a consensus on the definition of sarc Openia in order to make studies comparable and for implementation in clinical care.

TL;DR: The results suggest that perceptual decisions are mediated by oscillatory interactions within overlapping local and large-scale cortical networks.

What are the association patterns between handgrip strength and adverse health conditions? A topical review.
Ryan McGrath,Nathaniel Johnson,Lukus Klawitter,Sean Mahoney,Kara A Trautman,Caroline Carlson,Ella Rockstad,Kyle J. Hackney +7 more
TL;DR: Stand-alone handgrip strength should be considered an umbrella assessment of the body systems that contribute to strength capacity, and a panoptic measurement of muscle strength that is representative of overall health status, not a specific health condition.

The Longitudinal Associations of Handgrip Strength and Cognitive Function in Aging Americans.
Ryan McGrath,Brenda M. Vincent,Kyle J. Hackney,Sheria G. Robinson-Lane,Brian Downer,Brian C. Clark +5 more
TL;DR: Handgrip strength could be used for assessing cognitive status in aging Americans and strength capacity should be monitored in those with cognitive impairment, as strength capacity and cognitive function may parallel each other.

Neuromuscular Changes with Aging and Sarcopenia.
TL;DR: Findings over the past 15 years have demonstrated that changes in grip and leg extensor strength are not primarily due to muscle atrophy per se, and that to a large extent, are reflective of declines in the integrity of the nervous system.

The Relation between Finger Gnosis and Mathematical Ability: Can we Attribute Function to Cortical Structure with Cross-Domain Modeling?
TL;DR: A novel method for assigning function to local cortical structure is applied and a proposed local working is proposed—an array of pointers—that can be tested empirically and will allow for further elaboration of the redeployment view of the relation between finger and number representations.

Cross-education after high-frequency versus low-frequency volume-matched handgrip training.
TL;DR: In this article, the cross-education effects from a high-frequency (HF) versus a lowfrequency (LF) volume-matched handgrip training program on interlimb asymmetry was examined.

Childhood Cognitive Ability and Age-Related Changes in Physical Capability From Midlife: Findings From a British Birth Cohort Study.
TL;DR: It is suggested that childhood cognitive ability may be related to decline in physical capability in late midlife, and a number of life course pathways are implicated, including those linking childhood and adult cognitive ability.
Is there an inferior frontal cortical ne t work for cognitive control and inhibition
Franz-Xaver Neubert,Rogier B. Mars,Matthew F. S. Rushworth +2 more
- 01 Jan 2012
TL;DR: This chapter discusses how executive control is exerted by regions in the frontal lobes and suggests that the inferior frontal gyrus (IFG), particularly the right IFG, and the pre-supplementary motor area play a major role in inhibitory control and the adjustment of movement plans.
