Summary: The study found that there was stronger functional connectivity in the right dorsomedial prefrontal cortex (dmPFC) under emotional incongruence induced by preceding facial expressions when negative pictures were presented, and the dmPFC had stronger functional connectivity related to negative pictures following pleasant expressions. These results suggest that the functional connectivity of the dmPFC contributes to the resolution of emotional incongruence and reduces the impact of preceding information on subsequent emotional processes.

Summary: The study found that the connectivity between the caudate anterior head and thalamus is negatively correlated with hallucination severity, indicating the role of the caudate in sensory gating and auditory hallucinations. These findings offer a personalized treatment approach for auditory hallucinations.

Summary: Research indicates that foreign language can influence decision making by regulating emotional response to negative stimuli and enhancing emotional response to positive stimuli. This study explores the neural mechanisms of Chinese-English bilinguals during decision making, revealing that the second language can mediate loss aversion through the dorsolateral prefrontal cortex while enhancing the response to positive feedbacks via the hippocampus.

Summary: Recent research has shown that neural responses to unexpected behaviors from close versus distant others, and ingroup versus outgroup members, may be partly driven by differences in the strength of prior beliefs.

Summary: The dorsomedial prefrontal cortex/dorsal anterior cingulate cortex (dmPFC/dACC) is a brain area that has been the subject of numerous theories and debates regarding its functions. It has been associated with various cognitive processes, and understanding its function has been challenging for neuroscientists. This review explores the anatomy, functions, and theories surrounding the dmPFC/dACC, providing insights for future research.

Summary: This study investigated the audio-visual integration mechanism of emotional speech in the human brain, identifying the important role of the left insula in the integration process. Furthermore, the bilateral middle temporal gyrus (MTG), right inferior parietal lobule, and bilateral precuneus were also suggested to be involved in the integration of emotional speech from other aspects.

Summary: This paper introduces an extended version of the weighted prediction error (WPE) method that incorporates crossband filters to enhance modeling accuracy in the time-frequency domain. Two approaches to extending WPE while considering crossband filters are proposed and investigated. The first approach improves model accuracy but increases computational complexity, while the second approach maintains the same complexity as conventional WPE while achieving improved accuracy and comparable performance. Extensive simulations validate the effectiveness of the proposed methods, with experimental results showing both methods outperforming conventional WPE in dereverberation performance. These findings highlight the potential of incorporating crossband filters to improve the accuracy and efficacy of WPE for dereverberation tasks.

Summary: In this paper, a multi-scale emotional speech synthesis framework, MsEmoTTS, is proposed to model emotions from different levels. The framework utilizes an attention-based sequence-to-sequence model along with three emotion presenting modules to capture global emotion category, utterance-level emotion variation, and syllable-level emotion strength. Experimental results demonstrate the superiority of the proposed method in emotion transfer speech synthesis and text-based emotion prediction speech synthesis. The method also allows for flexible control of emotion expressions.

Summary: This study used fMRI to investigate the differences in brain activity between reading silently and reading aloud. The results indicated that reading silently compared to reading aloud was associated with activity in the auditory pathway and delayed activity in the primary auditory cortex.

Summary: Behavioral evidence suggests that reward prediction errors play a key role in episodic memory acquisition. In a novel task where RPEs were manipulated, fMRI results confirmed that signed RPEs are encoded in the ventral striatum and mediate their effects on episodic memory accuracy. Connectivity between processing areas and the hippocampus and ventral striatum increased with RPE value, supporting their central role in episodic memory formation.

Summary: This study investigated prediction error processing in depression and schizophrenia patients through meta-analyses, finding differences in brain activity between the two patient groups, suggesting a potential role of dopamine-rich areas in encoding prediction errors in both disorders.

Summary: Both conflict and error processing are associated with an increase in midfrontal theta power and hemodynamic activity in the anterior midcingulate cortex. This study used simultaneous EEG-fMRI technique to investigate the relationship between theta power and hemodynamic activity during conflict tasks. The results showed a negative correlation between conflict pre-response theta and BOLD signal in the midline area 9, while error-related theta showed a positive relationship with activity in the anterior midcingulate cortex.

Summary: Inner speech, a crucial cognitive process, remains poorly understood, especially its emotional characteristics. This study aims to identify the neural substrate for emotional dimension and brain structures responsible for suppressing expression in inner speech. A pilot fMRI study was conducted on 33 participants, who listened to pre-recorded phrases or words with different emotional connotations and internally spoke them with the same emotion or suppression of expression. The results revealed an emotional component in inner speech, encoded by similar structures as in spoken speech, and highlighted the unique role of the caudate nuclei in suppressing expression.

Summary: The present study used fMRI to investigate the neural correlates of contextualized emotional conflict control and domain-general conflict control. The results showed that both processes engaged neural areas in the frontoparietal network, suggesting similar neural mechanisms. However, there was a broader neural recruitment for emotional conflict control, with a possible lateralization of the lPFC. The gPPI analyses further demonstrated that emotional conflict control elicited broader synergistic activities in individuals' brain networks compared to domain-general conflict control.
