Background: Strabismus has been related to different alterations of brain functions and learning in children. Early treatment for visuomotor functions may improve the executive areas of intelligence. We undertook this study to demonstrate changes of visuomotor function and intelligence in children after strabismus treatment.
Methods: This is a prospective study of patients with strabismus, before and after treatment. We applied the Human Figure Test, Visuomotor Bender Test, and Intelligence Test.
Results: We included nine children with an average age of 8.7 years (± 2.4 years). Stereopsis result was 724 arc sec. Visual acuity was 0.16 logMAR ± 0.15. Verbal intelligence was 91.1 ± 11, executive intelligence (EI) was 86.7 ± 8, and global intelligence (GI) was 91 ± 10. Correlation coefficient of EI was significantly related to stereopsis (-0.2), visual acuity (-0.1) and Bender (-0.1). GI results were higher than statistical prognosis (88.16 for x = 90).
Conclusions: We demonstrated improvement in binocularity and psychoadaptive areas related to EI after strabismus and amblyopia treatment.

Functional Motor Disorders (FMD) consists in symptoms of altered motor function not attributable to typical neurological and medical conditions. This study aimed to explore explicit and perceptual measures of Sense of Ownership, Agency, and Body Schema in FMD patients, and assess whether these alterations are specific to FMD or shared with other functional disturbances. Twelve FMD patients, ten with Irritable Bowel Syndrome (IBS, a functional gastrointestinal disorder) and fifteen healthy controls (HC) underwent: (i) the Mirror Box Illusion (MBI), requiring participants to perform tapping movements with their dominant hand concealed from sight, while visual feedback was provided by an alien hand under visuo-motor congruency or incongruency conditions; (ii) a Forearm Bisection Task before and after exposure to the MBI, and the Embodiment Questionnaire after the MBI, as perceptual and explicit indices of the embodiment illusion, respectively.

The characterization of how precisely we perceive visual speed has traditionally relied on psychophysical judgments in discrimination tasks. Such tasks are often considered laborious and susceptible to biases, particularly without the involvement of highly trained participants. Additionally, thresholds for motion-in-depth perception are frequently reported as higher compared to lateral motion, a discrepancy that contrasts with everyday visuomotor tasks.

Background: In humans, most spontaneous recovery from motor impairment after stroke occurs in the first 3 months. Studies in animal models show higher responsiveness to training over a similar time-period. Both phenomena are often attributed to a milieu of heightened plasticity, which may share some mechanistic overlap with plasticity associated with normal motor learning.

Background: Congenital hypothyroidism's sequelae include visuomotor and intellectual developmental deficits. Visual-motor perception is a cognitive function related to academic performance. Intellect is the ability to learn and use acquired knowledge to solve and achieve goals.

A crucial component of this generalization behavior is our ability to compose/decompose a whole into reusable parts, an attribute known as compositionality. One of the fundamental questions in robotics concerns this characteristic: How can linguistic compositionality be developed concomitantly with sensorimotor skills through associative learning, particularly when individuals only learn partial linguistic compositions and their corresponding sensorimotor patterns? To address this question, we propose a brain-inspired neural network model that integrates vision, proprioception, and language into a framework of predictive coding and active inference on the basis of the free-energy principle.
