Summary: The study found that repetitive auditory stimuli led to decreased neural activity in the bilateral superior temporal gyri, while omissions activation increased neural activity in the bilateral middle temporal gyri. Additionally, areas including the supplementary motor area, caudate nucleus, anterior insula, frontal areas, and middle and posterior cingulate cortex showed persistent activity, possibly specialized for working memory maintenance.

Summary: This study investigated the effects of action errors and unexpected perceptual events on behavior and neural oscillations using scalp EEG. The results indicated that unexpected events had different impacts on behavior and frontal midline delta-to-theta dynamics during different post-error periods, supporting the concept of two distinct post-error stages.

Summary: Surprise signals a discrepancy between past and current beliefs, affecting how ongoing experiences are segmented into discrete perceived events. These effects are influenced by whether surprising moments contradict or bolster current predominant beliefs.

Summary: In this article, a method for compensating gain errors in current sensing for highly dynamic three-phase drives is presented. The method utilizes three current sensor measurements and does not require a machine plant model. By extracting redundant information from the neutral current measurement using mathematical relations with the time-varying dq current, the proposed method compensates for nonsymmetrical current sensor gain errors even in the presence of offset errors. The method utilizes a recursive sliding window least square method to minimize computation effort, making it suitable for online applications.

Summary: This study investigates how subgenome-divergent and -convergent transcription is mediated and harmonized in the hexaploid common wheat genome. The authors find that transposon elements with transcription factor binding ability play a role in this process. They create a catalog of genome-wide transcription factor-binding sites (TFBSs) to assemble a common wheat regulatory network and discover that differential evolutionary selection of ancient and recent transposon elements contributes to subgenome-divergent and -convergent regulation.

Summary: The meta-analysis revealed that the overall incidence of medication errors in hospitals in Saudi Arabia was estimated to be 44.4%, with prescribing errors, dispensing errors, and administration errors representing significant proportions. The study also found high between-study heterogeneity, indicating a need for further efforts to improve medication management systems and prevent harm to patients.

Summary: Clinical errors are a significant challenge in healthcare systems globally, with difficulties in obtaining accurate statistics. This study identified barriers to reporting clinical errors in university hospital operating theatres and intensive care units, highlighting individual and organizational problems that hinder error reporting. Addressing both individual and organizational issues is crucial in improving the reporting process.

Summary: This study examined the factors affecting odor recognition memory over short delay intervals, finding that recognition memory was better with highly dissimilar odor pairs and uncommon odors as targets. Familiarity, pleasantness, and intensity did not have a systematic effect on recognition memory.

Summary: A new error index called equivalent error (EE) was defined to evaluate the performance of coordinate measuring machines (CMMs), and a stochastic model based on EE was proposed for predicting CMM measuring accuracy. The study focused on analyzing position, straightness, and part errors of 3-axis CMMs with FXYZ configuration, showing that the EE-based model significantly improved the linear modeling of CMM performance.

Summary: Asking students to generate a prediction before presenting the correct answer can increase their curiosity and surprise. The higher the students' confidence in their prediction, the more pronounced the physiological marker of curiosity. Highly unexpected results evoke surprise, independent of the correctness of the prediction.

Summary: Errors can lead to unfavorable outcomes, but they also trigger adaptive mechanisms to optimize future behavior. Norman et al. have discovered a previously unknown direct projection in mice brains that modulates visual cortex network activity and enables attentional adaptation following errors.

Summary: The study found that ALIC/NAc DBS has a significant impact on reaction time in patients with OCD, and clinical efficacy may be associated with ERN amplitudes. Furthermore, the results suggest that DBS can affect the performance monitoring system, and propose the ERN as a potential future clinical predictor.

Summary: This systematic review explores the differences in cognitive control functions and neurometabolite levels between schizophrenia patients and healthy controls. The study finds that chronic patients show decreased GABA and glutamate concentrations, while the results for first-episode patients are mixed. The review also suggests that working memory and processing speed are associated with GABA and glutamate levels, but the relationship between metabolites and negative symptoms is inconsistent.

Summary: The study investigates the independent contributions of valence, surprise, and reward prediction errors (RPE) on the feedback-related neuronal signal, specifically the FRN and P3 components. With a large sample size of 992 healthy individuals, the results show that valence and surprise modulate the FRN, whereas both global and local surprise influence the P3. The behavioral adaptations after feedback and FRN have small associations. These findings support the theory of the FRN as a representation of a signed RPE and indicate that the P3 is involved in evaluating prediction errors in decision-making and learning tasks.

Summary: Both conflict and error processing are associated with an increase in midfrontal theta power and hemodynamic activity in the anterior midcingulate cortex. This study used simultaneous EEG-fMRI technique to investigate the relationship between theta power and hemodynamic activity during conflict tasks. The results showed a negative correlation between conflict pre-response theta and BOLD signal in the midline area 9, while error-related theta showed a positive relationship with activity in the anterior midcingulate cortex.

Summary: This study examined proactive control and binding effects in the context of task switching in adult patients with Tourette syndrome (TS). The results suggest that TS patients exhibit normal proactive control, but show altered perception-action binding processes. This indicates that TS patients have normal cognitive control, but abnormal integration between perception and action.
