“…In this sense, alterations are mainly related to activation, control in the preparation and/or pre-adjustment of the motor response [110]. Thus, deficits in motor response processing and preparation make it difficult to perform tasks involving sustained effort, activation and use of time, which lead to a diminished performance that is sufficiently severe to produce omission errors [108,111].…”

Impulsive and Omission Errors: Potential Temporal Processing Endophenotypes in ADHD

Temporal processing (TP) is associated with functions such as perception, verbal skills, temporal perspective, and future planning, and is intercorrelated with working memory, attention, and inhibitory control, which are highly impaired in individuals with attention deficit hyperactivity disorder (ADHD). Here we evaluate TP measures as potential endophenotypes in Caribbean families ascertained from probands affected by ADHD. A total of 232 individuals were recruited and clinically evaluated using an extensive battery of neuropsychological tasks and reaction time (RT)-based task paradigms. Further, the heritability (genetic variance underpinning phenotype) was estimated as a measure of the genetics apportionment. A predictive framework for ADHD diagnosis was derived using these tasks. We found that individuals with ADHD differed from controls in neuropsychological tasks assessing mental control, visual-verbal memory, verbal fluency, verbal, and semantic fluency. In addition, TP measures such as RT, errors, and variability were also affected in individuals with ADHD. Moreover, we determined that only omission and commission errors had significant heritability. In conclusion, we have disentangled omission and commission errors as possible TP endophenotypes in ADHD, which can be suitable to assess the neurobiological and genetic basis of ADHD. A predictive model using these endophenotypes led to remarkable sensitivity, specificity, precision and classification rate for ADHD diagnosis, and may be a useful tool for patients’ diagnosis, follow-up, and longitudinal assessment in the clinical setting.

“…The probability of match recognition decreased with increasing the interval between complementary subsets of dots. These results suggest the importance of the temporal coupling of information from two subsets of dot patterns, where data from two subsets of dots are separated by the duration, ranging from 0 to 500 ms (Gupta et al, 2020 ). Another experiment displayed the complementary subsets with 200 ms of separation, and the match recognition was disrupted when the random dot mask was displayed midway between the two subsets.…”

“…Previous experimental studies have also supported an important role of temporal coupling in different perceptual tasks (Bahmer and Gupta, 2018 ). Moreover, the temporal coupling of neural events during information processing underlying action and perception can be of different degrees, from a less tight to a more tight degree (Gupta et al, 2020 ). Furthermore, binding between two brain areas or a brain activity and an external stimulus feature can emerge from temporal coupling (von der Malsburg, 1995 ).…”

“…All living systems can sense external stimulations, process information, and make an appropriate reaction, or show adaptive behaviour. Many biological systems exhibit taxis as a response to environmental changes 1,2 . For example, organisms like E. coli have demonstrated chemotaxis phenomenon by changing their moving trajectories in response to a detectable chemical gradient 3 .…”

Taxis is ubiquitous in biological and physical chemistry systems as a response to various external stimulations. We prepared aqueous droplets containing Belousov-Zhabotinsky (BZ) solutions suspended on an oleic acid oil phase subject to DC electric field, and found that these BZ droplets undergo chemically driven translational motion towards the negative electrode under DC electric field. This electrotaxis phenomenon originates from the field-induced inhomogeneous distribution of reactants, in particular Br − ions, and consequently biased location of the leading centers towards the positive electrode. Chemical wave generated from the leading centre propagates passing the droplet centre of mass, and creates a gradient of interfacial tension when reaching the droplet-oil interface on the other side, resulting in a momentum exchange between the droplet and oil phases which drives the droplet move in the opposite direction of the electric field. A greater electric field strength renders stronger electrotaxis effect.
