Premotor projections from the locus coeruleus and periaqueductal grey are altered in two rat models with inborn differences in emotional behavior
Exp Brain Res. 2024 Feb 15. doi: 10.1007/s00221-024-06786-y. Online ahead of print.ABSTRACTEmotionally motivated behaviors rely on the coordinated activity of descending neural circuits involved in motor and autonomic functions. Using a pseudorabies (PRV) tract-tracing approach in typically behaving rats, our group previously identified descending premotor, presympathetic, and dual-labeled premotor-presympathetic populations throughout the central rostral-caudal axis. The premotor-presympathetic populations are thought to integrate somatomotor and sympathetic activity. To determine whether these circuits are dysregulated i...

Increasing auditory intensity enhances temporal but deteriorates spatial accuracy in a virtual interception task
Exp Brain Res. 2024 Feb 9. doi: 10.1007/s00221-024-06787-x. Online ahead of print.ABSTRACTHumans are quite accurate and precise in interception performance. So far, it is still unclear what role auditory information plays in spatiotemporal accuracy and consistency during interception. In the current study, interception performance was measured as the spatiotemporal accuracy and consistency of when and where a virtual ball was intercepted on a visible line displayed on a screen based on auditory information alone. We predicted that participants would more accurately indicate when the ball would cross a target line than wher...

The type 1 submovement conundrum: an investigation into the function of velocity zero-crossings within two-component aiming movements
Exp Brain Res. 2024 Feb 8. doi: 10.1007/s00221-024-06784-0. Online ahead of print.ABSTRACTIn rapid manual aiming, traditional wisdom would have it that two components manifest from feedback-based processes, where error accumulated within the primary submovement can be corrected within the secondary submovement courtesy of online sensory feedback. In some aiming contexts, there are more type 1 submovements (overshooting) compared to types 2 and 3 submovements (undershooting), particularly for more rapid movements. These particular submovements have also been attributed to a mechanical artefact involving movement termination...

Comparison of peripersonal space in front and rear spaces
This study aimed to investigate whether the size of the PPS changes depending on direction, with a particular focus on the disparity between the front and rear spaces. A vibrotactile stimulus was presented to measure PPS while a task-irrelevant auditory stimulus (probe) approached the participant. In addition, to evaluate the effect of the probe, a baseline condition was used in which only tactile stimuli were presented. The results showed that the auditory facilitation effect of the tactile stimulus was greater in the rear condition than in the front condition. Conversely, the performance on tasks related to auditory dist...

The effect of reward expectation on working memory of emotional faces under different levels of cognitive load: an ERP study
Exp Brain Res. 2024 Feb 3. doi: 10.1007/s00221-023-06776-6. Online ahead of print.ABSTRACTUsing event-related potentials (ERPs), this study examined the impact of reward expectations on working memory of emotional faces under different levels of cognitive load in a task combining the N-back paradigm and the reward expectation paradigm. The experiment involved presenting high- or low-reward cues followed by an N-back task for emotional faces with different loads. The accuracy results showed that under a high task load, both reward and emotion effects were significantly observed. However, these effects disappeared under a lo...

How body postures affect gaze control in scene viewing under specific task conditions
Exp Brain Res. 2024 Feb 1. doi: 10.1007/s00221-023-06771-x. Online ahead of print.ABSTRACTGaze movements during visual exploration of natural scenes are typically investigated with the static picture viewing paradigm in the laboratory. While this paradigm is attractive for its highly controlled conditions, limitations in the generalizability of the resulting findings to more natural viewing behavior have been raised frequently. Here, we address the combined influences of body posture and viewing task on gaze behavior with the static picture viewing paradigm under free viewing as a baseline condition. We recorded gaze data ...

Flanker interference at both stimulus and response levels decreases with age
Exp Brain Res. 2024 Feb 2. doi: 10.1007/s00221-023-06773-9. Online ahead of print.ABSTRACTWhen trying to identify the colour of a target, people's performance is impaired by nearby distractors of different colours. It is controversial whether these interference effects originate from competing stimuli, competing responses or from both simultaneously. These interference effects may also differ depending on a person's age. Comparisons between studies show mixed results, while differences in experimental design and data analysis complicate the interpretation. In our study, we manipulated the relative proportions of congruent ...

Variability of corticospinal and spinal reflex excitability for the ankle dorsiflexor tibialis anterior across repeated measurements in people with and without incomplete spinal cord injury
Exp Brain Res. 2024 Jan 25. doi: 10.1007/s00221-024-06777-z. Online ahead of print.ABSTRACTTo adequately evaluate the corticospinal and spinal plasticity in health and disease, it is essential to understand whether and to what extent the corticospinal and spinal responses fluctuate systematically across multiple measurements. Thus, in this study, we examined the session-to-session variability of corticospinal excitability for the ankle dorsiflexor tibialis anterior (TA) in people with and without incomplete spinal cord injury (SCI). In neurologically normal participants, the following measures were obtained across 4 days a...

Control of motor output during steady submaximal contractions is modulated by contraction history
Exp Brain Res. 2024 Jan 23. doi: 10.1007/s00221-023-06774-8. Online ahead of print.ABSTRACTThe purpose of the study was to investigate the influence of contraction history on force steadiness and the associated EMG activity during submaximal isometric contractions performed with the dorsiflexor muscles. The key feature of the protocol was a triangular ramp contraction performed in the middle of a steady contraction at a lower target force. The target force during the ramp contraction was 20% MVC greater than that during the steady contraction. Thirty-seven healthy individuals (21 men and 16 women) performed the submaximal ...
