Reducing alertness does not affect line bisection bias in neurotypical participants
Exp Brain Res. 2023 Nov 23. doi: 10.1007/s00221-023-06738-y. Online ahead of print.ABSTRACTAlertness, or one's general readiness to respond to stimulation, has previously been shown to affect spatial attention. However, most of this previous research focused on speeded, laboratory-based reaction tasks, as opposed to the classical line bisection task typically used to diagnose deficits of spatial attention in clinical settings. McIntosh et al. (Cogn Brain Res 25:833-850, 2005) provide a form of line bisection task which they argue can more sensitively assess spatial attention. Ninety-eight participants were presented with t...

Voluntary running wheel exercise induces cognitive improvement post traumatic brain injury in mouse model through redressing aberrant excitation regulated by voltage-gated sodium channels 1.1, 1.3, and 1.6
Exp Brain Res. 2023 Nov 23. doi: 10.1007/s00221-023-06734-2. Online ahead of print.ABSTRACTTraumatic brain injury (TBI) leads to disturbed brain discharge rhythm, elevated excitability, anxiety-like behaviors, and decreased learning and memory capabilities. Cognitive dysfunctions severely affect the quality of life and prognosis of TBI patients, requiring effective rehabilitation treatment. Evidence indicates that moderate exercise after brain injury decreases TBI-induced cognitive decline. However, the underlying mechanism remains unelucidated. Our results demonstrate that TBI causes cognitive impairment behavior abnormal...

The role of engagement and arousal in emotion regulation: an EEG study
Exp Brain Res. 2023 Nov 23. doi: 10.1007/s00221-023-06741-3. Online ahead of print.ABSTRACTCognitive reappraisal and expressive suppression are well-studied strategies of emotion regulation (ER). However, the results on their physiological basis are controversial. While in some studies, ER was accompanied by the inhibition of the nervous system, others suggested that ER even might increase arousal and engagement. We calculated the inter-subject correlation (ISC) and indices of engagement, valence and arousal of EEG during suppression, reappraisal, or natural watching of neutral and negative videos. First, both suppression ...

Perceived cognitive fatigue has only marginal effects on static balance control in healthy young adults
We examined the influence of perceived cognitive fatigue on static balance control in healthy young adults to gain greater clarity about this issue than provided in previous research. Based on the prevailing assumption in pertinent literature, we hypothesized that the influence of cognitive fatigue on balance control depends on the attentional effort required by the balance tasks being performed. To test this hypothesis, 44 young adults (24 women and 20 men) were alternately assigned to either the experimental group that was cognitively fatigued (using the 16-min TloadDback-task with individualized settings) or the control...

Facilitated adaptation via structural learning increases bimanual interference
In this study, we sought to further determine the role adaptation plays in bimanual interference using a structural learning paradigm to alter feedback regulation in reaching. We trained healthy participants to counter 60 unique random rotations in right hand visual feedback over 240 reaches. Following this, we assessed feedforward and feedback measures of interference in a bimanual reaching task where the right hand was exposed to a fixed visual feedback rotation while the left hand reached without visual feedback. We found that participants who had been exposed to the structural training task in the right hand showed inc...

The topographical attenuation of cutaneous input is modulated at the ankle joint during gait
Exp Brain Res. 2023 Nov 18. doi: 10.1007/s00221-023-06737-z. Online ahead of print.ABSTRACTThe attenuation of sensory inputs via various methods has been demonstrated to impair balance control and alter locomotor behavior during human walking; however, the effects of attenuating foot sole sensation under distinct areas of the foot sole on lower extremity motor output remains poorly understood. Thus, the purpose of this study was to attenuate cutaneous feedback via regional hypothermia under five different areas of the foot sole and investigate the resultant modulation of kinematic and muscle activity during level walking. ...

Exploring EEG resting state as a function of boredom proneness in pre-adolescents and adolescents
Exp Brain Res. 2023 Nov 17. doi: 10.1007/s00221-023-06733-3. Online ahead of print.ABSTRACTBoredom is a prominent experience commonly reported in school settings and associated with poor academic achievement. Little is known, however, about the age-related trajectory of boredom. Here we examined self-reported ratings of boredom in a cross-sectional sample of 8 to 15-year olds (n = 185) as a function of resting state EEG. Results indicated that reports of boredom in school rose as a function of age. Resting state EEG showed a decrease in theta power with age perhaps reflective of increased control. While no effects were evi...
