“…A similar initial bias was observed in the group exposed to an upward optical deviation, but it failed to reach significance. This representational bias was already shown in previous studies, which investigated manual line-bisection tasks ( Suavansri et al, 2012 ; Falchook et al, 2013 ; Churches et al, 2017 ; Chieffi et al, 2019 ) or perceptual line-bisection tasks (i.e., Landmark task; McCourt and Olafson, 1997 ; Fink et al, 2001 ). The upward bias would depend on object-based attention, because it has been shown to vary according to the shape of the stimulus to be bisected ( Churches et al, 2017 ) and to task instructions (i.e., comparison of line length versus center line estimation; Drain and Reuter-Lorenz, 1996 ).…”

“…Consequently, the majority of studies showed sensorimotor and cognitive aftereffects of lateral prism adaptation of healthy subjects (for a review, see Michel, 2016 ) and neglect patients (for a review, see Jacquin-Courtois et al, 2013 ). At a representational level (i.e., without prism adaptation), studies that investigated vertical line-bisection task showed an initial bias above the veridical center toward the upper part of space (e.g., Drain and Reuter-Lorenz, 1996 ; McCourt and Olafson, 1997 ; Fink et al, 2001 ; Suavansri et al, 2012 ; Falchook et al, 2013 ; Churches et al, 2017 ; Chieffi et al, 2019 ). This bias that testifies to an overrepresentation of the upper part of space and an underrepresentation of the lower part of space is called altitudinal pseudoneglect.…”

Sensorimotor aftereffects have been widely studied after lateral prism adaptation but not after vertical prism adaptation. It is thus well-known that lateral prism adaptation produces aftereffects on visuospatial representation and, recently, on auditory perception. This study aimed to explore the sensorimotor after-effects of vertical prism adaptation as well as its aftereffects on vertical visuospatial representation (Experiment 1) and on auditory frequency representation (Experiment 2). The experimental procedure was similar in both experiments: before and after prism adaptation to an upward or a downward optical deviation, healthy young participants performed an visual open-loop pointing task and a visual (Experiment 1) or an auditory (Experiment 2) perceptual bisection task. In the visual task, the participants had to indicate if they perceived the bisection as higher or lower than the true center of a line. In the auditory task, the participants had to indicate if they perceived the target auditory frequency closer to the low or the high limit of an auditory interval. For sensorimotor aftereffects, pointing errors were computed by means of a vertical touchscreen. For the perceptual bisection task, we measured the percentage of “down” (Experiment 1) or “low” responses (Experiment 2), and we computed the visual (Experiment 1) or the auditory (Experiment 2) subjective center for each participant. Statistical analyses were carried out separately for each optical deviation in each experiment. Sensorimotor aftereffects were observed in both experiments, in the opposite direction to the optical deviation (all ps < 0.01). No significant aftereffects occurred on visuospatial representation (all ps > 0.5), whereas the percentage of “low” responses and the auditory subjective center significantly increased after adaptation to a downward optical deviation (all ps < 0.05). Unlike lateral prism adaptation aftereffects that have been previously shown in both visuospatial horizontal representation and auditory frequency representation, aftereffects of vertical prism adaptation occurred in the auditory frequency representation but not in the vertical visuospatial representation. These results suggest that both vertical and lateral prism adaptations share a common substrate dedicated to the auditory modality (probably the temporal cortex), and that vertical adaptation does not act on the neural substrate of vertical visuospatial representation.

“…Indeed, Orx neurons synapse on VTA dopaminergic (DA) neurons, exciting them to promote arousal, while VTA GABAergic neurons synapse on LH Orx neurons to inhibit them and induce NREM sleep [ 34 , 35 ]. Orexin neurons also project densely to the BF cholinergic neurons to drive wakefulness and to promote attention and motivated behavior [ 15 , 36 , 37 , 38 , 39 , 40 ]. Meanwhile, LH Orx neurons receive projections from BF glutamatergic and GABAergic neurons, and these neuronal circuitries may consolidate the wakefulness required for attention [ 40 ].…”

Orexins, or hypocretins, are excitatory neuropeptides involved in the regulation of feeding behavior and the sleep and wakefulness states. Since their discovery, several lines of evidence have highlighted that orexin neurons regulate a great range of physiological functions, giving it the definition of a multitasking system. In the present review, we firstly describe the mechanisms underlining the orexin system and their interactions with the central nervous system (CNS). Then, the system’s involvement in goal-directed behaviors, sleep/wakefulness state regulation, feeding behavior and energy homeostasis, reward system, and aging and neurodegenerative diseases are described. Advanced evidence suggests that the orexin system is crucial for regulating many physiological functions and could represent a promising target for therapeutical approaches to obesity, drug addiction, and emotional stress.

“…The visuomotor system uses spatial representations generated within the fronto-parieto-cerebellar network, in which the occipitoparietal/dorsal stream and cerebellum play a crucial role [ 107 , 108 , 109 , 110 , 111 ]. The dorsal stream, combining retinotopic and spatiotopic/body-centered coordinates, supports the planning and execution of real-time visually-guided actions [ 112 , 113 , 114 , 115 , 116 , 117 , 118 ]. The cerebellum is responsible for the muscular coordination of the distal portions of the limbs, with particular reference to hands and digits.…”

The Neglected Factor in the Relationship between Executive Functioning and Obesity: The Role of Motor Control

Background: The association between obesity and executive functions (EFs) is highly controversial. It has been suggested that waist circumference (WC), compared to body mass index (BMI), is a better indicator of fat mass and EFs in obesity. Moreover, according to the viewpoint that the brain’s functional architecture meets the need for interactive behavior, we hypothesize that the relationship between EFs and body weight might be mediated by the motor performance. Methods: General executive functioning (frontal assessment battery-15), additional cognitive subdomains (trail making test and digit span backward), and motor performance (finger tapping task) were assessed in a sample that included 330 volunteers (192 females, M age = 45.98 years, SD = 17.70, range = 18–86 years). Results: Hierarchical multiple regression analysis indicated that the FAB15 score and FTT negatively predicted WC but not BMI. A subsequent mediation analysis highlighted that the indirect effect of FAB15 on WC through finger tapping was statistically significant. Conclusions: Our results suggest that WC, as compared to BMI, is a more effective measure for studying the association between EFs and body weight. Still, we found that the motor domain partially mediates the dynamics of such a relationship.
