Summary: Transdiagnostic approaches in psychiatry have the potential to overcome the limitations of traditional diagnostic paradigms. This study identified four stable functional domains that transcend diagnosis, related to negative valence, cognition, social functioning, and inhibition/arousal. The use of connectopic mapping and machine learning also showed promise in predicting transdiagnostic functional domains based on individualized topographic representations.

Summary: This study investigated the brain functional connectivity patterns related to lie detection tasks using EEG signals. The results showed that deceptive responses elicited greater oscillatory synchronization than truthful responses between different brain regions. The findings suggest that these functional connections play a crucial role in executing lying tasks, involving visuo-spatial imagery, attention and memory systems, and attention and inhibition processing. The proposed method, FTRPS, demonstrated high classification accuracy for identifying deception behavior.

Summary: This study investigates the functional connectivity associated with ADHD risk in children aged 2.5 and 3.5 years using functional near-infrared spectroscopy. The findings suggest differences in the parietal-frontal network in toddlers at risk for ADHD, potentially advancing the understanding of the neural mechanisms underlying the development of ADHD.

Summary: The neural mechanisms of human standing, particularly the postural response to external perturbations, involve various areas in the central nervous system. Recent research has shown that the corticospinal pathway plays a crucial role in generating an appropriate postural response and is influenced by temporal prediction. This study investigates how temporal prediction affects neural oscillations and synchronization between sensorimotor and distal areas, providing insights into the processing of cortical activities in preparation for optimal responses.

Summary: This study introduces a new methodology for extracting functional brain networks from multichannel scalp EEG recordings, focusing on investigating functional integration and segregation in brain networks. Statistical analysis reveals that frequency-specific graph measures have high discriminative ability between seizure and non-seizure intervals. The results show that during seizure activities, brain networks become more segregated and less aggregated compared to non-seizure intervals.

Summary: The study revealed that children with ADHD showed higher functional connectivity in the frontal and occipital lobes compared to healthy children, as well as longer shortest path lengths. This suggests issues in the brain emotional processing center and lower efficiency of information transmission and segregation in ADHD neuronal networks.

Summary: This paper proposes a method to study functional connectivity of the human brain using multilayer networks, where each layer represents a different frequency band. The study shows that following an error response, the brain forms communities across frequencies, particularly between theta and gamma bands, while this is not observed following a correct response.

Summary: Habitat loss leads to biodiversity loss and reduces the connectivity of landscapes for species movement. Quantifying functional connectivity is important for conservation management, and a technique based on population synchrony has been suggested. This study uses species survey data to investigate population synchrony for British birds and butterflies over time. Results show that butterfly synchrony has declined but recently increased, while bird synchrony has shown some decline followed by recovery. Developing indicators of functional connectivity using abundance data is crucial for effective land management strategies.

Summary: This study demonstrates that selective attention in children during a set-shifting task is dependent on theta-band phase resetting, with the preferred theta phase angle predicting reaction time. Enhanced oscillatory coupling between ACC and the dorsal attention network, along with decoupling from the default mode network, was observed during task performance. When transient focal epileptic activity occurs, impairments in phase resetting and connectivity changes result in prolonged reaction times.

Summary: This study found that while the whole-brain resting-state functional network organization is highly similar across individuals with various mental disorders, subtle differences in network graph distance can predict diagnosis. The results suggest a need to reevaluate neurocognitive theories of mental illness, with a focus on subtle functional brain network changes.

Summary: Studies have found that certain brain regions are activated during attentional deployment via long-term memories. We conducted an analysis of task-based functional connectivity to study the communication between these brain regions underlying long-term memory guided attention. Our results showed that different subnetworks, such as default mode, cognitive control, and dorsal attention, contribute differently to long-term memory guided attention, and the connectivity at the network level shifts based on attentional demands. We also found specific nodes within these subnetworks that play a crucial role in facilitating long-term memory guided attention.

Summary: Attention deficit hyperactivity disorder (ADHD) is a common behavioural disorder in children, and its pathogenesis is not fully understood. This study proposes a new model, Deep CSAF, to learn the important factor matrices in non-linear functional magnetic resonance imaging (fMRI) data. Experimental results show that Deep CSAF achieves superior performance in ADHD diagnosis.

Summary: The brainstem noradrenergic locus coeruleus (LC) and the prefrontal cortex (PFC) are reciprocally connected, allowing for mutual influence. Transient increases in PFC high y power may indicate changes in LC activity. Synchronized PFC neuronal spiking during high y transients may provide a new mode of top-down control over the LC.

Summary: The noradrenergic locus coeruleus (LC) plays a crucial role in controlling brain and behavioral states. It has been found that different ensembles of spontaneously coactive LC neurons could lead to diverse cortical states, with some showing high-frequency power increase and others showing decreased high-frequency power.

Summary: The mind affects the body through the central nervous system's control of the autonomous nervous system. It has been observed that illusions perceived as bright lead to pupil constriction in humans, but it was not known if this response also occurs in other animals. This study found that rats exhibit the same pupil response to the brightness illusion as humans, suggesting that the mind-body connection is not exclusive to humans and the primary visual cortex may play a role in this connection.

Summary: Researchers have developed ultraflexible stim-nanoelectronic threads that enable low-threshold, high-resolution, and chronic stable intracortical microstimulation. They have demonstrated seamless integration with the nervous tissue, stable neuronal activation, and long-lasting behavioral responses without causing tissue damage or exacerbation of side effects.
