Influence of visual feedback and cognitive challenge on the age-related changes in force steadiness
This study determined the impact of altered visual feedback on force steadiness in the presence of a difficult cognitive challenge in young and older men and women. Forty-nine young (19-30 yr; 25 women, 24 men) and 25 older (60-85 yr; 15 women; 10 men) performed low force (5% of maximum) static contractions with the elbow flexor muscles in the presence and absence of a cognitive challenge (counting backwards by 13) either with low or high visual feedback gain. The cognitive challenge reduced force steadiness (increased force fluctuation amplitude) particularly in women (cognitive challenge × sex: P < 0.05) and older in...

Unpleasant emotion inhibits attentional focus toward a peripheral target in a visual search: an ERP study
Exp Brain Res. 2024 Apr 3. doi: 10.1007/s00221-024-06796-w. Online ahead of print.ABSTRACTPrevious studies have found that emotional states affect the extent of attention, and the effect has been explained by adaptive views. If the adaptive explanations are true, emotion should modulate attentional focus toward a peripheral stimulus. The present study investigated if emotion affects the focus of attention toward a peripheral target in a visual search paradigm with event-related brain potential (ERP) measurement. In each trial of the experiment, participants performed a visual search task after an emotion (unpleasant, neutr...

Healthy adults favor stable left/right hand choices over performance at an unconstrained reach-to-grasp task
Exp Brain Res. 2024 Apr 2. doi: 10.1007/s00221-024-06828-5. Online ahead of print.ABSTRACTReach-to-grasp actions are fundamental to the daily activities of human life, but few methods exist to assess individuals' reaching and grasping actions in unconstrained environments. The Block Building Task (BBT) provides an opportunity to directly observe and quantify these actions, including left/right hand choices. Here we sought to investigate the motor and non-motor causes of left/right hand choices, and optimize the design of the BBT, by manipulating motor and non-motor difficulty in the BBT's unconstrained reach-to-grasp task....

Total sleep deprivation effects on the attentional blink
Exp Brain Res. 2024 Apr 2. doi: 10.1007/s00221-024-06826-7. Online ahead of print.ABSTRACTThe Attentional Blink (AB) is a phenomenon that reflects difficulty in detecting or identifying the second of two successive targets (T1 and T2) that are presented in rapid succession, between 200-500ms apart. The AB involves indicators of attentional and temporal integration mechanisms related to the early stages of visual processing. The aim of this study was to identify the effects of 24-h of sleep deprivation (total sleep deprivation, TSD) on the attentional and temporal integration mechanisms of the AB. Twenty-two undergraduate s...

Activation of NLRP3 inflammasome in a rat model of cerebral small vessel disease
Exp Brain Res. 2024 Apr 2. doi: 10.1007/s00221-024-06824-9. Online ahead of print.ABSTRACTCerebral small vessel disease (CSVD) is increasingly being recognized as a leading contributor to cognitive impairment in the elderly. However, there is a lack of effective preventative or therapeutic options for CSVD. In this exploratory study, we investigated the interplay between neuroinflammation and CSVD pathogenesis as well as the cognitive performance, focusing on NLRP3 signaling as a new therapeutic target. Spontaneously hypertensive stroke-prone (SHRSP) rats served as a CSVD model. We found that SHRSP rats showed decline in l...
