Summary: The study demonstrates that group-level models of neural activity built using movie-watching data can achieve remarkable prediction performance across large areas of the cortex, even beyond sensory-specific areas. These encoding models not only learn high-level concepts that generalize to task-bound paradigms, but also show great potential as powerful tools for studying brain function.

Summary: FCD is the most common cause of drug-resistant focal epilepsy in children and young adults, and the diagnosis relies on histopathological assessment of surgical brain tissue. Challenges exist in diagnosing FCD and its subtypes, necessitating continuous research and consensus for a reliable classification scheme. Combining clinical, imaging, histopathology, and molecular studies will help define the disease spectrum and develop specific treatment options for FCD.

Summary: This study examined the relationship between cortical activation patterns measured with functional near-infrared spectroscopy and PTSD symptom improvement in youth. The results showed a positive correlation between cortical activation and PTSD symptom improvement slopes, specifically in the bilateral dlPFC in response to fearful and neutral facial stimuli. The use of fNIRS provides a cost-effective and portable method for monitoring and assessing cortical activation patterns, which may have promising implications for understanding emotion dysregulation in clinical populations.

Summary: Transcranial electrode stimulation (tES) is a non-invasive brain stimulation technique that modulates cortical activities by delivering weak electric currents through scalp-attached electrodes. The direction and magnitude of the electric field (EF) are crucial factors determining the cortical response to tES. This study, using a multi-scale model, demonstrates the importance of neuronal morphology and biophysical properties in predicting the cellular targets of non-invasive brain stimulation.

Summary: The study investigates the neural mechanisms underlying conscious recognition and finds that recognized images elicit enhanced activation in more brain regions, with specific content activity in both activated and deactivated cortical networks. Additionally, recognition-related category information can be decoded from widespread cortical activity but not subcortical activity.

Summary: This study reveals that intracortical demyelination after mild traumatic brain injury is significantly more severe than in typical aging, with different regions of the brain affected differently. Occipital regions may be more susceptible to primary injury, while temporal, cingulate, and insular regions are more vulnerable to later manifestations of injury sequelae.

Summary: This study investigated the brain activation during emotion-regulation tasks in bipolar disorder (BD) patients using fMRI. The results showed hyperactivation in the caudate, amygdala, precentral gyrus, middle frontal gyri, and sub-gyrus, and hypoactivation in the inferior frontal gyrus and anterior cingulate gyrus in BD patients compared to healthy controls. These findings suggest the presence of structural and functional abnormalities in emotional processing in BD.

Summary: Traumatic brain injury (TBI) is a major cause of morbidity and mortality worldwide, with no targeted therapies available. The functions and mechanisms of NG2-glia, the largest population of regenerative cells in the mature cortex, are not well understood in the context of TBI. This study synthesizes results from multiple rodent models and proposes future avenues for exploring the role of NG2-glia in TBI, suggesting that targeting these cells may enhance local cellular recovery.

Summary: The study found that functional connectivity increased across the entire brain during fear extinction learning, predicting the performance of extinction memory. These results support recent research implicating distributed brain regions in learning, consolidation, and expression of fear extinction memory in the human brain.

Summary: The human sense of smell and ability to distinguish odors play a crucial role in extracting valuable information from the environment and influencing human behavior. Utilizing the activation likelihood estimation method, studies have analyzed neural activation patterns for different odor categories, revealing clear differences in how the brain responds to these categories.

Summary: Isolated cortical vein thrombosis (ICVT) is a rare type of cerebral venous thrombosis that is often misdiagnosed as a brain tumor. Anticoagulant treatment is the main therapeutic strategy, but surgical thrombectomy may be a viable alternative.

Summary: Regressing voxel time course onto expected response is a common procedure in functional magnetic resonance imaging. The analysis of the time-derivative approach provides functional relations between time shift and regression coefficients, allowing for hemodynamic shifts of +/- 5 s, and explaining shape distortion and reconstruction behavior.

Summary: Traumatic brain injury (TBI) can result in serious long-term consequences, including Alzheimer's, Parkinson's, or disability. Mild TBI (mTBI) is the most common type, and early detection is crucial for successful treatment. While neuroimaging-based tests provide structural and functional mapping of the brain, they lack temporal resolution and may not detect mTBI. On the other hand, electroencephalogram (EEG) has good spatial and temporal resolution, but currently cannot confidently detect mTBI. This paper aims to review existing approaches and explain the shortcomings of EEG-based mTBI detection.

Summary: This study examines the relation between cortical structural covariance at birth and later infant behavior. The results suggest that coordinated maturation of multi-modal neonatal cortical features is related to developmental outcomes and that network organization at birth serves as an early infrastructure for future functional skills.

Summary: The study explores the impact of spatial integration on neuroglial populations during brain activity, revealing the correlation between integrative models and brain activity, indicating that the integration process of brain activity is independent of neuroimaging techniques, and suggesting that brain activity reflects a networked integrative process.

Summary: Research has shown that action inhibition efficiency is poorer in the audiovisual modality compared to visual and auditory modalities. In high-level decisional conflict, bimodal stimulation is not processed as a simple multisensory object improving performance, but as concurrent visual and auditory information, increasing task demands and impairing the ability to revise responses.

Summary: This research protocol utilizes fNIRS to analyze cortical changes in children with single-sided deafness and their relationship with auditory and language skills, providing important insights for developing individualized rehabilitation programs for untreated SSD children. By comparing cortical measures between SSD and normal hearing children and studying their association with binaural hearing, speech perception and production, and quality of life, the study aims to prevent long-term neurofunctional and clinical consequences.
