Cortical projection from the premotor or primary motor cortex to the subthalamic nucleus in intact and parkinsonian adult macaque monkeys: a pilot tracing study

Borgognon, Simon ; Cottet, Jérôme ; Badoud, Simon ; Bloch, Jocelyne ; Brunet, Jean-François ; Rouiller, Eric M.

In: Frontiers in Neural Circuits, 2020, vol. 14, p. -

Besides the main cortical inputs to the basal ganglia, via the corticostriatal projection, there is another input via the corticosubthalamic projection (CSTP), terminating in the subthalamic nucleus (STN). The present study investigated and compared the CSTPs originating from the premotor cortex (PM) or the primary motor cortex (M1) in two groups of adult macaque monkeys. The first group...

The right thalamic ventral posterolateral nucleus seems to be determinant for macrosomatognosia: a case report

ElTarhouni, Amir H. ; Beer, Laura ; Mouthon, Michael ; Erni, Britt ; Aellen, Jerome ; Annoni, Jean-Marie ; Accolla, Ettore ; Dieguez, Sebastian ; Chabwine, Joelle N.

In: BMC Neurology, 2020, vol. 20, no. 1, p. 393

Background: Macrosomatognosiais the illusory sensation of a substantially enlarged body part. This disorder of the body schema, also called “Alice in wonderland syndrome” is still poorly understood and requires careful documentation and analysis of cases. The patient presented here is unique owing to his unusual macrosomatognosia phenomenology, but also given the unreported localization...

A systematic review and meta-analysis on neural adaptations following blood flow restriction training: what we know and what we don’t know

Centner, Christoph ; Lauber, Benedikt

In: Frontiers in Physiology, 2020, vol. 11, p. -

Objective: To summarize the existing evidence on the long-term effects of low-load (LL) blood flow restricted (BFR) exercise on neural markers including both central and peripheral adaptations.Methods: A systematic review and meta-analysis was conducted according to the PRISMA guidelines. The literature search was performed independently by two reviewers in the following electronic databases:...

Augmented-feedback training improves cognitive motor performance of soccer players

Hicheur, Halim ; Chauvin, Alan ; Cavin, Vincent ; Fuchslocher, Joerg ; Tschopp, Markus ; Taube, Wolfgang

In: Medicine & Science in Sports & Exercise, 2020, vol. 52, no. 1, p. 141–152

Purpose In this study, we tested the hypothesis that augmented feedback (AF) training can improve both perceptual–cognitive and/or motor skills specific to soccer.Methods Three groups of young elite players (U14–U15 categories) performed a test consisting in passing the ball as accurately and as quickly as possible toward a visual target moving briefly across a large screen located at 6 m...
