Summary: This study found that language functions in patients with brain AVMs were normal compared to controls. In different language tasks, AVM patients showed increased activations in the right hemisphere, particularly in the frontal lobe during oral word reading and in the temporal lobe during auditory sentence comprehension tasks.

Summary: The study demonstrated that semantic and phonological association tasks resulted in crossed cerebro-cerebellar language lateralization activations similar to those observed in the covert verb generation task. This suggests the possibility of using these tasks in conjunction with the traditional verb generation task, especially for subjects who may be unable to perform the latter.

Summary: The study evaluated the efficacy of fMRI based on Chinese tasks in protecting language function in epileptics. Different tasks activated distinct brain regions mainly in the temporal lobe and frontal lobe. A personalized surgical plan using fMRI and intraoperative EEG can protect language function and improve patients' quality of life postoperatively.

Summary: The perception and cognitive interpretation of time duration is subjective and connected with arousal and interoceptive signals. This study found that the insula, a critical brain region for integrating information from the external world with the organism's inner state, plays a central role in the perception of time duration and contributes to its estimation accuracy. The results also showed that the right anterior insular cortex and inferior frontal gyrus are involved in the accurate perception of temporal duration.

Summary: Lymphomas are ideal targets for radiomics due to their distinct characteristics, and functional imaging tests play a crucial role in diagnosing and predicting treatment outcomes for lymphoma. However, more data is needed to support the application of radiomics in lymphoma due to differences in lymphoma subtypes and increasing treatment options.

Summary: Recent research has shown that silent gestures exhibit systematicity in representing events, challenging the holistic interpretation. Untrained gesturers systematically manipulate the form of their gestures when representing events with and without a theme, supporting the idea of systematicity. Handshape features, co-opted from cognitive systems, could integrate into emerging sign languages.

Summary: Silent gestures, although previously believed to lack linguistic properties, have been found to exhibit systematicity and consistent strategies in representing objects and events. Researchers demonstrated that untrained gesturers manipulate the form of their gestures based on the transitivity of the events they represent. By using handshape features, linear support vector machines were able to predict transitivity distinctions in silent gestures with good accuracy. These findings suggest that handshape features are a cognitive construct that may integrate into emerging sign languages, and that nonsigners tend to map event participants to each hand, reflecting a cognitive foundation of this strategy.

Summary: This study aimed to explore the potential clinical utility of functional and structural magnetic resonance imaging (MRI) in the diagnosis of depression in Parkinson's disease (DPD). The results showed that both the ReHo value of the left dorsolateral superior frontal gyrus and the DC value of the left inferior temporal gyrus were equally well suited for the diagnosis and differential diagnosis of DPD, with a combination of them being slightly preferable. The multimodal MRI technique represents a promising approach for the classification of subjects with PD.

Summary: The study investigates the effects of semantic dissimilarity in foreign language learning using event-related potential (ERP) analysis of electroencephalography (EEG) signals. Results show that even with a short learning cycle, semantically matched and mis-matched end-words in English sentences replaced with their Japanese counterparts elicit different EEG patterns similar to the native language case. Additionally, the newly learned word stimuli show the presence of a delayed and opposite polarity P600 component, predominantly observed in the parietal region and left hemisphere. The absence of the N400 component suggests its association with long-term memory processing, while a P3a component is observed for the Japanese end-words before semantic learning.

Summary: This study investigates the relationship between hemodynamic lag and cerebrovascular reactivity (CVR) following stroke using functional magnetic resonance imaging (fMRI). The findings suggest that the hemodynamic responses derived from fMRI can be affected by vascular insult, resulting in reduced magnitude and temporal delays in the response. However, the contribution of altered CVR to hemodynamic lag is negligible, and other factors, such as intrinsic neural network dynamics, may play a larger role.

Summary: The study suggests that the human cerebellum is involved in a wide range of cognitive tasks beyond traditional motor control and can be divided into distinct functional subregions. By utilizing a naturalistic paradigm of fMRI, the research successfully identified different subregions of the cerebellum, providing an alternative template for exploring neural activities in naturalistic environments.

Summary: Objective Action Observation Treatment is a promising approach that utilizes a neurophysiological mechanism to recruit neural structures for rehabilitation through the mere observation of actions. Using this treatment method in a telerehabilitation setting has proven to be effective in the rehabilitation of children with Cerebral Palsy.

Summary: Recent studies have shown that limb apraxia is a common higher motor impairment following stroke, with a tendency to be underestimated and impacting daily life and personal independence. This pilot study investigates explicit motor learning in apractic stroke patients, focusing on their ability to learn and retain new explicit sequential finger movements over 10 training sessions. Findings suggest that stroke patients with ideomotor apraxia can acquire and maintain a novel sequence of movements, with training potentially improving symptoms of apraxia.

Summary: The processing of observed actions and verbs expressing motor content is supported by the same neural mechanisms, suggesting embodiment. Hand motor responses were slower during the observation of hand actions and processing of hand-related verbs compared to foot actions and related verbs, indicating a modulation of hand motor responses regardless of modality.

Summary: We propose a novel method to extract stimulus-related neural dynamics from naturalistic functional magnetic resonance imaging (fMRI) by isolating dynamic changes in brain functional connectivity (FC) using a low-rank plus sparse decomposition approach. Our method improves the detection of stimulus-induced group-level homogeneity in FC and captures inter-subject variability by exploiting shared network structure among subjects receiving the same naturalistic stimuli.
