Summary: The study revealed that schizophrenia patients have a normal architecture of source contributions underlying MMN and P3a responses at the primary frontocentral scalp electrode, but with increasing impairment from temporal to frontal sources. These findings accelerate the clarification of neural networks related to MMN reduction at Fz in schizophrenia patients.

Summary: The aim of this study was to investigate speech processing development in children with normal hearing and cochlear implants using a multifeature event-related potential paradigm. The results showed differences in the responses to easy and difficult to detect changes between the two groups, with the cortical speech discrimination of children with cochlear implants developing late. The study also found that multisensory activities such as parental singing can improve the discrimination and attention shifting toward speech changes in children with cochlear implants.

Summary: This study aimed to explore potential brain indexes of attention deficit hyperactivity disorder (ADHD) in adults. The results showed that patients with ADHD had higher levels of distractibility and significant differences were found in the amplitude of the Reorienting Negativity (RON) component in the event-related brain potentials (ERPs) analysis. The findings suggest that the RON response may serve as a potential biomarker for deficient re-orienting of attention in adults with ADHD.

Summary: This study found that language categorization influences face identification. Participants were more likely to confuse faces within the same language category than between different language categories. At the neural level, early vMMN responses were stronger for faces from different language categories, while larger vMMNs were obtained for faces from the same language category at a later stage.

Summary: The early posterior negativity (EPN), a mid-latency ERP component, can be reliably enhanced by emotional cues, with a deflection beginning between 150 and 200 msec after stimulus onset. The brief, bilateral occipital EPN is followed by the centroparietal late positive potential (LPP), a long duration slow-wave strongly associated with emotional arousal ratings of scenes. A recent study suggests that the EPN is particularly sensitive to human bodies in scenes, independent of emotional intensity.

Summary: This paper discusses the emotion-related late positive potential (LPP) of the event-related potential (ERP), and argues that the function of the LPP is still uncertain. By linking the LPP to the P300 component of the ERP and exploring its connections to memory and emotional memory research, the author suggests that the LPP may be related to memory processes.

Summary: This study investigated the effects of sleep deprivation on attention capture in young and older adults. The results showed that sleep deprivation attenuated the differences in reaction times between standard and deviant stimuli in young adults, but not in older adults. Older adults exhibited a reduced P3a and larger RON amplitude compared to young adults. These findings suggest that older adults may adopt different neural processing strategies to compensate for age-related declines in attention capture.

Summary: This study found that the visual mismatch negativity (vMMN) in the categorization of visual stimuli showed no significant difference in amplitude between between-category and within-category deviants. This suggests that abstract categorical representations may not always be automatically processed at early visual stages, demonstrating limitations in generalizing findings from the auditory domain to the visual domain.

Summary: Athletes' behavior, thoughts, and feelings are influenced by whether they achieve their personal goals or not. This experiment aimed to assess the application of using unresolved goals to induce state rumination in athletes. Results showed that cueing unresolved goals significantly increased state rumination in athletes compared to a control condition. The study also found temporal changes in athletes' mood and affect, with no significant group differences.

Summary: This study aimed to explore the neuro-cognitive processes underlying visually induced motion sickness (VIMS) by analyzing EEG data. The results indicated a potential increase in delta power in the centro-parietal regions and a decrease in alpha power in the central regions for participants experiencing mild-moderate VIMS compared to those with minimal VIMS. Furthermore, the differences in EEG activity between the two groups became more pronounced with increasing duration of a trial. These findings suggest that EEG may be sensitive to differences in information processing in VIMS and minimal VIMS contexts, and may serve as a neurophysiological correlate of VIMS.

Summary: The phenomenon of vection, which refers to the sensation of self-motion in the absence of physical motion, has been studied by researchers for over a century. Due to the lack of objective measures or physiological correlates, subjective methods have been commonly used to quantify vection. These measures can be classified into vection occurrence, temporal characteristics, vection quality, and indirect measures. This review provides an overview and critical evaluation of the most commonly used vection measures, and offers recommendations for selecting appropriate measures to improve the comparability of vection research findings.

Summary: Healthy aging is associated with impairments in face recognition, which may arise from difficulties in the earliest perceptual stages of visual information processing. Older adults show less selective and less lateralized N170 responses to faces, indicating age-related de-differentiation of specialized face networks can be detected by ERPs.

Summary: This study used resting-state functional magnetic resonance imaging to explore the relationship between individual's spontaneous neural activity and social interaction anxiety in a nonclinical population. The results showed that social interaction anxiety was correlated with the fractional amplitude of low-frequency fluctuations in several brain regions, and that emotional intelligence partially mediated this relationship. This study provides evidence for the neural basis of social interaction anxiety in the normal population and highlights the role of emotional intelligence in this anxiety.

Summary: This study provides morphometric data on the development of the human medullary arcuate nucleus (AN) by examining the brains of preterm and perinatal infants. The results show that AN morphology demonstrates asymmetry and individual variability during the fetal period. The volume and neuronal number of AN increase exponentially with age, while neuronal density decreases exponentially. The AN may undergo neuron death and neuroblasts production after mid-gestation.

Summary: This study investigated the effects of alamandine on allodynia in a rat model and found the presence of MrgD receptors in the vlPAG and RVM regions. Microinjection of alamandine resulted in a significant increase in paw withdrawal threshold and could be blocked by an MrgD receptor antagonist. Upregulation of MrgD receptor expression following allodynia induction suggests a potential compensatory mechanism in response to pain.

Summary: The present study aimed to investigate the separate and combined effects of anodal transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) and left dorsolateral prefrontal cortex (F3) regions on pain relief in patients with type-2 diabetes suffering from neuropathic pain (NP). The results showed that tDCS had the potential to induce pain relief in patients with type-2 diabetes suffering from NP. The mean perceived pain intensity in the posttest was lower in the M1 stimulation group than in the F3 stimulation group. However, more trials with larger sample sizes are necessary to define clinically relevant effects.

Summary: This study found a general impairment in humor comprehension in individuals with schizophrenia, with mental jokes being more difficult for both patients and controls. Humor comprehension was closely associated with the patients' overall pragmatic and linguistic profile, while the association with Theory of Mind (ToM) was minimal. Another notable finding was the increased appreciation of humor in individuals with schizophrenia, who rated jokes as funnier than controls did, regardless of whether they were correctly or incorrectly completed. The funniness ratings were not predicted by any measure, suggesting a dimension of humor untied to cognition or psychopathology.
