Alterations in attention to cues signaling the need for inhibitory control play a significant role in a wide range of psychopathology. However, the degree to which motivational and attentional factors shape the neurocomputations of proactive inhibitory control remains poorly understood. The present study investigated how variation in monetary incentive valence and stake modulate the neurocomputational signatures of proactive inhibitory control. Adults (N = 46) completed a Stop-Signal Task (SST) with concurrent EEG recording under four conditions associated with stop performance feedback: low and high punishment (following unsuccessful stops) and low and high reward (following successful stops). A Bayesian learning model was used to infer individual’s probabilistic expectations of the need to stop on each trial: P(stop). Linear mixed effects models were used to examine whether interactions between motivational valence, stake, and P(stop) parameters predicted P1 and N1 attention-related

uncovered in studies of female mice that collectively show the vital important of sex as a determinant of fear extinction. Furthermore, they demonstrate the relevance of age, from adolescence to older age, to fear extinction in rodents and describe how sex and age interact in the expression of this form of memory. They identify gaps in both the animal and human literature and make recommendations on how these should be addressed in the future in order to make progress in understanding fear extinction across the whole population.Continuing the theme of translation of findings in animal models to the human sphere, food-seeking behaviour in both rodents and humans is the focus of the article contributed by Gladding and colleagues [5]. In particular, they examine the role of cues in driving excess energy intake and the complex bidirectional relationships between both obesity and highly palatable highfat/high-sugar diets and cognitive impairments. They focus on rodent and human studies that

Mashup Score: 3Plexin B3 guides axons to cross the midline in vivo - 4 day(s) ago
During the development of neural circuits, axons are guided by a variety of molecular cues to navigate through the brain and establish precise connections with correct partners at the right time and place. Many axon guidance cues have been identified and they play pleiotropic roles in not only axon guidance but also axon fasciculation, axon pruning, and synaptogenesis as well as cell migration, angiogenesis, and bone formation. In search of receptors for Sema3E in axon guidance, we unexpectedly found that Plexin B3 is highly expressed in retinal ganglion cells of zebrafish embryos when retinal axons are crossing the midline to form the chiasm. Plexin B3 has been characterized to be related to neurodevelopmental disorders. However, the investigation of its pathological mechanisms is hampered by the lack of appropriate animal model. We provide evidence that Plexin B3 is critical for axon guidance in vivo. Plexin B3 might function as a receptor for Sema3E while Neuropilin1 could be a co-r

Mashup Score: 7Brain vital sign monitoring of sleep deprivation detects situational cognitive impairment - 4 day(s) ago
Objective, rapid evaluation of cognitive function is critical for identifying situational impairment due to sleep deprivation. The present study used brain vital sign monitoring to evaluate acute changes in cognitive function for healthy adults. Thirty (30) participants were scanned using portable electroencephalography before and after either a night of regular sleep or a night of total sleep deprivation. Brain vital signs were extracted from three established event-related potential components: (1) the N100 (Auditory sensation); (2) the P300 (Basic attention); and (3) the N400 (Cognitive processing) for all time points. As predicted, the P300 amplitude was significantly reduced in the sleep deprivation group. The findings indicate that it is possible to detect situational cognitive impairment due to sleep deprivation using objective, rapid brain vital sign monitoring.

The four articles in this collection provide insight into the different aspects of digital treatments for OCD. The bibliometric analysis by Tang et al., 2023 shows that research on OCD has steadily increased over the past two decades. One of the key areas is research on the treatment of OCD including CBT. However, the bulk of the research has been conducted in high-income countries. The authors propose that insufficient funding and inadequate quality of research may be reasons for the lack of contributions from low-and middle-income countries. The study of videoconferencing-based ERP by Murphy et al., 2023 is a good example of recent, large-scale naturalistic studies from clinical settings. An earlier study by the same group (Feusner et al., 2022) showed that videoconferencing-based ERP was effective and treatment gains were enduring. The treatment has a positive impact on comorbid depression and anxiety and the quality of life of the patients. It could reduce costs by reducing the the
