Exercise-induced central and peripheral sympathetic activity in a community-based group of epilepsy patients differ from healthy controls
In this study, exercise-induced changes of the interrelation of central and peripheral autonomic activity in patients with epilepsy was assessed. 21 patients with epilepsy (16 seizure-free), and 21 healthy matched controls performed an exhaustive bicycle ergometer test. Immediately before and after the exercise test, resting state electroencephalography measurements (Brain Products GmbH, 128-channel actiCHamp) of 5 min were carried out to investigate functional connectivity assessed by phase locking value in source space for whole brain, central autonomic network and visual network. Additionally, 1-lead ECG (Brain products...

Posture enhancement with cerebellum transcranial electrical stimulation: a systematic review of current methods and findings
Exp Brain Res. 2024 Mar 28. doi: 10.1007/s00221-024-06808-9. Online ahead of print.ABSTRACTRecently, transcranial electrical stimulation (tES) has gained increasing popularity among researchers, especially for recovery and improvement, but interpretation of these results is difficult due to variations in study methods and outcome measurements. The main goal of this study was to better understand the postural and balance indicators affected by cerebellar tES, as the cerebellum is the main brain region responsible for controlling balance. For this systematic literature review, three databases were searched for articles where...

Walking (and talking) the plank: dual-task performance costs in a virtual balance-threatening environment
Exp Brain Res. 2024 Mar 27. doi: 10.1007/s00221-024-06807-w. Online ahead of print.ABSTRACTWe evaluated the effects of engaging in extemporaneous speech in healthy young adults while they walked in a virtual environment meant to elicit low or high levels of mobility-related anxiety. We expected that mobility-related anxiety imposed by a simulated balance threat (i.e., virtual elevation) would impair walking behavior and lead to greater dual-task costs. Altogether, 15 adults (age = 25.6 ± 4.7 yrs, 7 women) walked at their self-selected speed within a VR environment that simulated a low (ground) and high elevation (15 m) se...

Working memory load modulates anticipatory postural adjustments during step initiation
Exp Brain Res. 2024 Mar 25. doi: 10.1007/s00221-024-06820-z. Online ahead of print.ABSTRACTWorking memory (WM) can influence selective attention. However, the effect of WM load on postural standing tasks has been poorly understood, even though these tasks require attentional resources. The purpose of this study was to examine whether WM load would impact anticipatory postural adjustments (APAs) during step initiation. Sixteen healthy young adults performed stepping tasks alone or concurrently with a WM task in a dual-task design. The stepping tasks involved volitional stepping movements in response to visual stimuli and co...

Type of auditory cues and apparatus influence how healthy young adults integrate sounds for dynamic balance
Exp Brain Res. 2024 Mar 25. doi: 10.1007/s00221-024-06819-6. Online ahead of print.ABSTRACTIt is unclear whether the brain handles auditory cues similarly to visual cues for balance. We investigated the influence of headphones and loudspeaker reproduction of sounds on dynamic balance performance when an individual is facing a cognitive challenge. Twenty participants (16 females, aged 19-36) were asked to avoid a ball according to a specific visual rule. Visuals were projected from the HTC Vive head-mounted display in an acoustically controlled space. We varied the environment by adding congruent sounds (sounds coincide wit...

[ < sup > 3 < /sup > H]-NFPS binding to the glycine transporter 1 in the hemi-parkinsonian rat brain
Exp Brain Res. 2024 Mar 25. doi: 10.1007/s00221-024-06815-w. Online ahead of print.ABSTRACTL-3,4-dihydroxyphenylalanine (L-DOPA) is the main treatment for Parkinson's disease (PD) but with long term administration, motor complications such as dyskinesia are induced. Glycine transporter 1 (GlyT1) inhibition was shown to produce an anti-dyskinetic effect in parkinsonian rats and primates, coupled with an improvement in the anti-parkinsonian action of L-DOPA. The expression of GlyT1 in the brain in the dyskinetic state remains to be investigated. Here, we quantified the levels of GlyT1 across different brain regions using [3H...

Sleep deprivation induces late deleterious effects in a pharmacological model of Parkinsonism
Exp Brain Res. 2024 Mar 18. doi: 10.1007/s00221-024-06811-0. Online ahead of print.ABSTRACTParkinson's disease is a degenerative, chronic and progressive disease, characterized by motor dysfunctions. Patients also exhibit non-motor symptoms, such as affective and sleep disorders. Sleep disorders can potentiate clinical and neuropathological features and lead to worse prognosis. The goal of this study was to evaluate the effects of sleep deprivation (SD) in mice submitted to a progressive pharmacological model of Parkinsonism (chronic administration with a low dose of reserpine). Male Swiss mice received 20 injections of re...
