Summary: This study investigated thalamocortical connectivity during different stages of non-rapid eye movement (NREM) sleep using scalp electroencephalograms and local field potentials. The results showed that the connectivity from the cortex to the thalamus was the most prominent. The strength of connectivity varied between sleep stages, but the direction and frequency remained stable. These findings suggest a relatively stable thalamocortical connectivity during NREM sleep.

Summary: Interhemispheric interactions in stroke patients show significant imbalance, with the affected hemisphere unable to trigger motor potentials while the unaffected hemisphere maintains inhibition onto the affected. Patients with better recovery in hand function exhibit more stable interhemispheric balance. Additionally, microstructural integrity of callosal fibers is associated with interhemispheric connectivity and suppression of TMS-evoked activity.

Summary: This commentary article compares the differences between their recently published paper on cerebellar transcranial magnetic stimulation (TMS) induced electroencephalographic responses and Gassmann et al.'s previous work on the same topic. The authors agree that the differences mainly stem from the use of different magnetic stimulation coils but raise two unanswered questions: (1) which method is most likely to achieve optimal activation of cerebellar output, and (2) to what extent are the evoked cerebellar responses contaminated by concomitant sensory input? They emphasize the importance of careful experimental design and combining electrophysiological and behavioral data for obtaining reliable TMS-EEG data.

Summary: Transcranial alternating current stimulation (tACS) can influence perception and behavior, and recent evidence suggests its potential impact in clinical settings. However, the underlying mechanisms of tACS are still poorly understood. In this study, the researchers attenuated stimulation artifacts and provided evidence for phase-dependent enhancement and suppression of visually evoked steady state responses (SSR) during amplitude-modulated tACS (AM-tACS). The findings suggest the feasibility and superiority of closed-loop AM-tACS over conventional open-loop AM-tACS in purposefully modulating brain oscillations at specific frequencies.

Summary: A real-time compatible artifact rejection algorithm (SASS) was introduced to overcome limitations in adapting stimulation parameters to ongoing brain oscillations. By using SASS, stimulation-specific signal components could be reliably removed while leaving physiological signal components unaffected. Results indicate that SASS can be used to establish adaptive AM-tACS, providing a potentially powerful tool to target various brain functions and investigate how AM-tACS interacts with electric brain oscillations.

Summary: Using intracranial electroencephalography, this study investigated the amygdala, orbitofrontal cortex (OFC), and medial prefrontal cortex (mPFC) and found that they play important roles in the emotion circuit. The three regions showed different emotion-induced responses and interactions. The results demonstrated greater broadband gamma activity in the negative condition, increased beta activity in the amygdala and OFC, and decreased beta activity in mPFC during the emotional picture viewing task. Furthermore, model-based computational analyses revealed unidirectional connectivity from mPFC to the amygdala and bidirectional communication between OFC-amygdala and OFC-mPFC.

Summary: Alzheimer's disease (AD) is a common type of dementia and currently has no cure. Interictal epileptiform discharges (IEDs) in AD patients are markers of a more aggressive disease course, but there are challenges in standardizing the definition and capturing methods of IEDs. IEDs are an attractive treatment target, but there is uncertainty about when to treat them, the optimal drugs and doses, and the impact of treatment on the disease course.

Summary: This study retrospectively analyzed the medical records of 561 Greek patients with myotonic dystrophies. The findings show similarities in clinical and genetic characteristics between these patients and those from other regions. Muscle weakness is the first symptom in both types of myotonic dystrophies, while multisystemic involvement and cataracts are common manifestations. The study highlights the importance of specialized neuromuscular centers that can provide genetic counseling and a multidisciplinary approach.

Summary: In order for fashion outfits to be aesthetically pleasing, the garments need to be compatible in terms of style, category, and color. A new architecture called VICTOR is proposed to address the issue of compatibility in outfit-making applications, providing regression for overall compatibility and detection of mismatching items. The architecture utilizes fashion-specific language-image pre-training to fine tune computer vision neural networks. The results show that VICTOR outperforms the current state-of-the-art while reducing floating operations. The code for VICTOR is available on GitHub.

Summary: This study analyzes the biography, language, and literary work of Greek novelist Demosthenes Voutyras, and hypothesizes that his mystical and dark writing style could be attributed to medial temporal interictal dynamics. We suggest that the psycholiterary profile of Voutyras is consistent with the idiosyncratic characteristics of the temporal lobe personality, while a non-dominant temporal lobe contribution has been proposed.

Summary: This review discusses the relevance of central concepts from the Lurian corpus of theories to the modern neuropsychology of epilepsy and epilepsy surgery. It highlights the limitations of quadrant-based views and data-driven approaches in clinical reasoning, and advocates for a systemic view inspired by Luria's work. Luria's theory and clinical approaches apply to the entire neuropathology spectrum and provide a holistic understanding of neurocognition. This systemic approach aligns with the network approach in neuroimaging.
