Summary: This study found significant variations in multicenter rectal cancer MRI data, mainly attributed to differences in hardware and image acquisition, as well as segmentation methodology and radiomics feature extraction software. Variations in ADC were largely explained by differences in hardware and acquisition, while patient-intrinsic factors had minimal impact. Reproducibility was good to excellent between different segmentation methods and software packages, with higher-order features showing less reproducibility.

Summary: The aim of this study was to investigate the antidepressant efficacy of bilateral theta-burst stimulation (biTBS) in patients with major depressive disorder (MDD) and its effects on brain responses measured by functional magnetic resonance imaging (fMRI) during emotional processing. The results showed that the biTBS group had significantly decreased depression scores at week 8, and this difference persisted during the 24-week follow-up period. At week 4, patients in the biTBS group exhibited increased brain activities over the left superior and middle frontal gyrus during negative emotional stimuli.

Summary: This paper introduces a toolbox called MR-TIM for head tissue modeling from structural magnetic resonance images, which generates highly realistic 3D masks through image pre-processing, tissue probability mapping, and tissue segmentation. The validation shows that MR-TIM is more accurate than alternative approaches for whole-head tissue segmentation, which may contribute to a more widespread use of EEG as a brain imaging technique.

Summary: This study investigates the effects of baclofen on the neuronal reward system in patients with alcohol use disorder. The results show that the BAC group exhibits a reduced neural activity pattern compared to the placebo group, indicating that baclofen may enable a more flexible neuronal adaptation through the modulation of insular information processing, leading to a successful alcohol detoxification.

Summary: This longitudinal study found that face-selective neural response was positively associated with RAN, and the neural response to spoken and written words in preliterate children was negatively associated with RAN in the dorsal temporo-parietal language system. Stronger neural activity in the inferior and middle temporal gyri at kindergarten age was associated with higher reading performance.

Summary: Two meta-analyses were conducted to examine the effects of non-invasive brain stimulation on visual perspective taking. Stimulation of the right temporoparietal junction significantly improved visibility judgment from an allocentric perspective, while dorsomedial prefrontal cortex stimulation influenced performance from an egocentric perspective. However, there was not strong evidence that these regions play a crucial role in Level-2 visual perspective taking with higher requirements of mental rotation.

Summary: This study found that the pre-supplementary motor area (pre-SMA) is positively correlated with pure effort demand, while the ventromedial prefrontal cortex (vmPFC) shows the opposite effect. Additionally, brain regions previously implicated in value integration in other cost domains, such as the ventromedial prefrontal cortex and ventral striatum, consistently signal net value. These findings suggest that different brain regions are involved to varying degrees in processing effort costs and integrating values.

Summary: Studies in decision neuroscience have found robust neural representations for the value of choice options. However, it is not well understood how the brain evaluates different attributes and combines them into overall values. This study used functional magnetic resonance imaging and found that attribute values were associated with activity in the posterior cingulate cortex, ventral striatum, and posterior inferior temporal gyrus, while overall values were represented in dorsolateral and ventromedial prefrontal cortex. Ultimately, this research suggests that certain brain regions are key for integrating attribute values and overall values.

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.
