Social-emotional processing difficulties have been reported in Anorexia Nervosa (AN), yet the neural correlates remain unclear. Previous neuroimaging work is sparse and has not used functional connectivity paradigms to more fully explore the neural correlates of emotional difficulties. Fifty-seven acutely unwell AN (AAN) women, 60 weight-recovered AN (WR) women and 69 healthy control (HC) women categorised the gender of a series of emotional faces while undergoing Functional Magnetic Resonance Imaging. The mean age of the AAN group was 19.40 (2.83), WR 18.37 (3.59) and HC 19.37 (3.36). A whole brain and psychophysical interaction connectivity approach was used. Parameter estimates from significant clusters were extracted and correlated with clinical symptoms. Whilst no group level differences in whole brain activation were demonstrated, significant group level functional connectivity differences emerged. WR participants showed increased connectivity between the bilateral occipital face area and the cingulate, precentral gyri, superior, middle, medial and inferior frontal gyri compared to AAN and HC when viewing happy valenced faces. Eating disorder symptoms and parameter estimates were positively correlated. Our findings characterise the neural basis of social-emotional processing in a large sample of individuals with AN.

Initial findings linking Virtual Reality (VR)-based encoding to increased recollection at retrieval remain inconclusive due to heterogeneous study designs and dependence on behavioral data. To clarify under which circumstances VR-based encoding affects or enhances episodic memory retrieval, the fundamental question remains whether the encoding modality, i.e.

Micro-charity, with its ease of dissemination, is an effective way to support public welfare. Gratitude has been shown to promote prosocial behavior. However, its specific role in driving micro-charity sharing, particularly the underlying neural correlates, remains unclear.

This research proposes an advanced technique to manipulating milk flow and its thermal characteristics through a dynamic electromagnetic pathway, effectively managing the non-linear thermal behavior of milk. This study employs advanced artificial intelligence (AI) to create a sophisticated analytical framework for modeling the complex interactions between milk flow, hybrid nanoparticles (Ag-ZnO), and dynamic thermal conditions in a squarely activated electromagnetic tunnel. The research focuses on optimizing key steps in dairy manufacturing-microbial reduction and texture stabilization by analyzing the behavior of Ag-ZnO/milk under oscillating thermal amplification, incorporating radiant heat and Darcy drag effects.

The neural circuits that transmit the sense of pain and how pain is encoded by these circuits are still poorly understood.Mechanical allodynia is a prominent form of chronic pain characterized by painful responses to innocuous touch that develops as a consequence of nerve damage and inflammation. Here, we show that alterations to the normal log-normal distribution of neuronal activity and structure of neural correlations between neurons in the dorsal column nuclei (DCN) constitute a signature feature of mechanical allodynia, with the transmission of "allodynic" light touch information to the thalamus by somatostatin-positive projection neurons in the DCN being essential for its expression and development.

Objective: To compare brain activity before voluntary movement and before the same movement when it was released from suppression. This study examined the Bereitschaftspotential (BP) and beta band event-related desynchronization (bERD) during active blink suppression, contrasting these with voluntary blinking, where these EEG correlates of motor preparation are well-established.
Methods: Fifteen healthy adults performed voluntary blink and blink suppression-release tasks with EEG recording.
