   Cognitive and emotional load in the course of increasing the complexity of tasks leads to the activation of various parts of the autonomic nervous system (ANS) and can be accompanied by an increase in the efficiency of problem solving. An increase in cognitive load under the condition of high motivation is a stress factor and is expressed in a different reaction of the sympathetic and parasympathetic links in response to the load. This study explored the ANS reactions by measuring the pupil size of 61 healthy sub-clinical volunteers in response to the gradually increasing complexity of tasks. The experiment included 3 blocks of a combined visual search and 1-back task with six levels of difficulty. K-mean clustering method was used for the analysis. An increase in the complexity of the task from the first to the sixth level led to different dynamics of the pupil size in the three clustered groups. In one group, an intense high switchability and an active reaction with a large amplitude of changes were visible, in the second group the dynamics of changes was minimal, and a third intermediate group was also identified. Our results highlight individual differences in the reaction of the sympathetic and parasympathetic branches of ANS under cognitive workload depending on biometric and psychometric parameters.

  Rapid semantic processing: an MEG study of narrative text reading

  Research has shown that semantic analysis occurs at early stages of word processing (less than 200 ms). While traditional studies have focused on isolated words/sentences, our research explores rapid semantic processing during reading stories when texts were presented word by word (each word lasting 150 ms), enhancing rapid semantic processing. We sorted words by quartiles according to their semantic dissimilarity (SD) and computed event-related fields (102 magnetometers) in 27 adult participants. Cluster-permutation analysis revealed two significant clusters of brain activity within early time windows (120–132 ms) that differentiated words according to their SD: positive in the right occipital region and negative in the left temporal region. In both clusters less pronounced responses were registered for words with lowest SD which corresponds to theories of predictive coding. These findings broaden our understanding of rapid semantic processing and suggest new methodology to study neurophysiological mechanisms of reading.

  AWARE: Alert Watcher and Astronomical Rapid Explorer

  We present the software aware for automatic scheduling the observations with the ground based network of optical telescopes GRB-IKI-FuN (extendable on other facilities). It was designed to provide the optimal coverage of large uncertainty contours of LIGO/Virgo/KAGRA (LVK) gravitational wave events, and gamma-ray bursts (GRBs), detected by space missions, which is crucial for fast look-up for their optical counterparts. In addition, aware provides capabilities for notifying users on new alert messages received from General Coordinate Network (GCN), and sharing final products generated by the planner via Telegram bot. The implementation of the software allows both scheduler, and Telegram bot to run concurrently in near real-time. In this paper, we discuss main follow-up tactics of LVK events, and GRBs. We overview the automatic planning software aware in terms of an architecture and algorithms. The example products made by aware since the beginning of the LVK O4 run on 25 May 2023 are given. The plans for future work are briefly discussed.

  Stress Resilience (Proprioceptive and Verbal Individual Differences) in Onco-Patients, Sportsmen and Controls

  The characteristics of response to stressful situations depend on a complex of factors such as personality traits, emotional regulation, health state, features of the nervous system, motor functions and proprioception. In cases of disruption of the brain's dopamine system due to disease or chemotherapy, hormone discharge due to stress, changes in emotions and proprioception may occur. The aim of our study was to find the relationship of stress resilence in verbal test and individual differences performed in proprioceptive test in onco-patients, sportsmen and group of control; as well as to observe the differences between these groups in the verbal stress resistance and individual differences proprioceptive tests. The results showed that onco-patients were less resistant as per verbal stress resistance outcomes for a major part of variables compared to other groups. The sportsmen were superior in verbal Risk and Control dimensions compared to other groups; but less in Positive Affectiveness. The proprioceptive test perfomance revealed the only statistically significant difference in performance in the dimension related to Mood, showing more Pessimism in the sportsmen group, but more Optimism in the oncopatients at temperamental (or intrisinc) level. The obtained results can be used by psychologists, therapists, coach and healthcare when needed to attend the specific needs of public, being pateints or sportsmen, etc.
