Summary: Loneliness is a significant risk factor for illness and death, but its impact on subsequent prosocial behavior is not well understood. To address this research gap, we investigated the neurobiological mechanisms underlying loneliness using a modified public goods game. Our findings demonstrate that loneliness leads to decreased prosocial actions and is associated with specific neurophysiological components, indicating that loneliness triggers coping strategies for self-preservation. This study contributes to our understanding of the neurobiological basis of loneliness and its effects on prosocial behavior.

Summary: Understanding how event-related potentials (ERPs) change following repeated assessments is crucial for advancing our understanding of neural mechanisms in psychopathology. This study examined P300 amplitude and latency changes across repeated assessments and the associations with depressive symptoms. Results showed a significant reduction in P300 amplitude and latency over assessments, and a consistent association between reduced P300 amplitude and trait anhedonia across assessments.

Summary: Feedback processing is commonly studied by analyzing the brain's response to discrete events. Recent animal work suggests that midbrain dopaminergic activity can track moment-to-moment changes in reward, but there is a debate whether this activity reflects reward prediction errors or state values. In this study, researchers developed an EEG measure of continuous feedback processing and found that scalp-recorded potentials were consistent with reward anticipation and tonic dopamine release, supporting the hypothesis that this activity is related to reward prediction errors.

Summary: The study found that bilingual speakers of Chinese-Malay background and monolingual Chinese speakers show similar processing of semantic congruency effects in Chinese, but significant differences were observed in the global field power data, indicating that bilinguals differ from monolinguals in terms of brain activity when processing classifier-noun pairs with different congruency effects.

Summary: Pain can increase neural activity in the reward circuit and enhance the desire for rewards, but the temporal modulation of pain on reward processing is still unclear. This study recorded electroencephalogram while participants received win or loss feedback in a gambling task, and found that pain increased the P300 amplitude for both types of feedback but did not affect feedback-related negativity (FRN). Pain only enhanced the power of win feedback in delta oscillation, while FRN and theta oscillation responded more to loss feedback but were unaffected by pain. These findings highlight the impact of pain on high-level cognitive processes associated with reward.

Summary: This study examined neurophysiological differences in adolescents with and without a history of preschool-onset depression (PO-MDD) using electroencephalography (EEG). The results showed that adolescents with a history of PO-MDD had smaller doors-P300 amplitude during cognitive exploration, while there were no group differences in reward feedback. Furthermore, smaller doors-P300 amplitude was associated with lower baseline income-to-needs ratio, older age, and female gender.

Summary: Selective encoding was studied by manipulating the value of specific stimuli for participants to remember. It was found that participants paid more attention to high-reward items in mixed lists but treated both high and low-reward items equally in pure lists. The results suggest that reward-enhanced memory is influenced by both automatic dopaminergic interactions and meta-cognitive strategies.

Summary: This study used electrophysiological methods to investigate expectancy fulfillment and semantic integration processes in the processing of binding and compound nouns in Chinese. The results showed a graded N400 effect at the central region and significant semantic integration effect in both experiments. The study suggests the possible coexistence of expectancy fulfillment mechanism indexed by the P300 and semantic integration mechanism indexed by the N400.

P600/LPC amplitudes were more positive-going in the PC group for MI congruent statements, and N400 amplitudes were significantly correlated with negative affect level within the PC group.

Summary: Behavioral and ERP studies have revealed that speaker gaze can influence listeners' expectations and be considered an integral part of the communicative signal. This study further investigates the role of speaker gaze in confirming referential expectations induced by linguistic context. Results indicate that gaze cue directed towards unexpected referents attenuated effects on subsequent referring nouns, providing strong evidence for the importance of gaze in communication.

Summary: This systematic review examines the relationship between socioeconomic status (SES) and scalp event-related brain potentials (ERPs), identifying amplitude variations in various ERPs that suggest impaired neural activity in low-SES individuals compared to high-SES individuals. The findings also suggest that the relationship between SES and certain ERP components may be influenced by the developmental stage of the study participants. The results highlight the sensitivity of distinct neural processes to SES differences and raise considerations for future research in this field.

Summary: There is a recognition in the neuroscience community that enhancing the replicability of studies on the relationship between brain activity and cognitive phenomena requires high statistical power and standardized analysis pipelines. In response, the #EEGManyLabs project has been launched to replicate key findings from influential EEG studies through international collaboration. The project aims to update confidence in EEG discoveries, create an open access database for future research, and promote a cultural shift towards inclusive, high-powered multi-laboratory collaborations.

Summary: This study examines the role of working memory in age differences in Theory of Mind (ToM) and whether education and culture moderate this relationship. The results show that older adults in Malaysia have poorer ToM compared to the UK sample, and this effect is mediated by working memory, especially at lower levels of education. These findings highlight the importance of considering cultural and educational differences in researching age differences in ToM.

Summary: This study examined the brain's response to different types of errors by observing feedback-related EEG activity. The results revealed that selection errors elicited a larger feedback-related negativity (FRN) and were correlated with behavioral adjustment, while execution errors produced a different pattern of FRN and error positivity, which were not correlated with subsequent changes in behavior.

Summary: This paper reports the results of a systematic review on the effects of daytime electric light exposure on alertness and higher cognitive functions. The study found that both short-wavelength dominant light exposure and higher intensity white light exposure increased alertness, but the effects varied depending on factors such as participants' sleep drive and the timing of light exposure. The relationship between light exposure and higher cognitive functions was not straightforward, and optimal light properties for cognitive functions depended on task complexity and control light properties.

Summary: This study examines the functional connectivity changes in individuals with sudden sensorineural hearing loss (SSNHL) at the integrity, network, and edge levels. The findings reveal reduced intranetwork connectivity strength and increased internetwork connectivity in SSNHL patients. These alterations are associated with the duration of SSNHL and Tinnitus Handicap Inventory scores. The study provides crucial insights into the neural mechanisms of SSNHL and the brain's network-level responses to sensory loss.

The results showed sex-specific anxiety and depression behaviors in the model group, as well as differences in protein expression and neurotransmitter levels between male and female mice. These findings enhance our understanding of sex-specific differences in depression and support tailored interventions.

Summary: This study explores the effects of prolonged mask usage on the human brain by analyzing EEG and physiological parameters. The results show that the mean EEG spectral power in alpha, beta, and gamma sub-bands of individuals wearing masks is smaller than those without masks. The performances on cognitive tasks and oxygen saturation level differ between the two groups, while blood pressure, body temperature, and heart rate are similar. The analysis also reveals that the occipital and frontal lobes exhibit the greatest variability in channel measurements.
