Summary: This study introduces a new learning scheme based on voltage-dependent synaptic plasticity rules, which can learn efficient representations by locally balancing feedforward inputs. It overcomes the limitations of traditional Hebbian-like plasticity, particularly for complex high-dimensional inputs and inhibitory transmission delays. The results suggest the importance of dendritic excitatory-inhibitory balance and voltage-dependent synaptic plasticity in representation learning.

Summary: The gastropod mollusk Aplysia is an important model organism used in cellular and molecular neurobiological studies. By studying the improved transcriptome of the Aplysia nervous system, researchers can explore the evolution of cognitive capacity at the molecular level. Comparing Aplysia with the octopus, it was found that both have a similar complement of genes linked to neuronal function, but vertebrates have more isoforms of certain scaffold proteins. This analysis provides insights into the evolution of the synaptic proteome and suggests that synaptic proteins and plasticity evolved gradually.

Summary: This study presents a computational predictive model for the dynamics of short-term synaptic plasticity (STP) induced by deep brain stimulation (DBS) at different frequencies. The model-based approach integrates multiple frequencies of DBS-like electrical stimulation as pre-synaptic spikes and infers the parameters of the TM model from the post-synaptic currents. By distinguishing between steady-state and transient responses, a dual optimization algorithm is developed to track the model parameters in two steps. The applicability of the method is confirmed through empirical data from rodent brain slices.

Summary: Overconsumption of high-fat diet can lead to neuroadaptive responses in the brain's reward circuitry, contributing to eating disorders. This study reveals that high-fat diet consumption hinders the suppression of sucrose-seeking in mice triggered by threat cues. It is found that enhanced cue-triggered neuronal activity in the anterior paraventricular thalamus, resulting from microglia activation induced by high-fat diet, contributes to this compulsive sucrose-seeking behavior.

Summary: This study evaluated the effectiveness of directional subthalamic stimulation in Parkinson's disease based on intraoperatively recorded beta oscillations. The results showed a strong correlation between clinical efficacy and beta activity, and selecting the contacts with the highest beta peaks improved the therapeutic window. Long-term follow-up showed similar improvements in both groups, validating the efficacy of directional stimulation guided by intraoperative beta oscillations.

Summary: Neurons and glial cells have membranes that express ion channels, transporters, and receptors, which generate voltage fluctuations. The high frequency components of the voltage signal reflect neuronal activity, while the low frequency components, known as the local field potential (LFP), provide information about synaptic inputs. This review emphasizes the importance of considering active dendritic mechanisms in understanding the genesis and location-dependent dynamics of LFPs.

Summary: A brief period of monocular deprivation induces short-term plasticity of the adult visual system. The impact of MD on neural correlates of multisensory processes is assessed. Results reveal eye-specific changes in neural activities associated with visual and multisensory processes. MD increases excitability to visual events for the deprived eye and audio-visual and auditory input for the non-deprived eye.

Summary: This study investigates a network called the multi-plasticity network (MPN) that relies solely on synapse modulation during inference to process task-relevant information. The results show that the MPN outperforms recurrent neural networks (RNNs) on neuroscience-relevant tests and its computational capabilities in synaptic modulation are comparable to networks with recurrent connections.

Summary: Sleeplessness can lead to a range of neuropsychiatric disorders in both juveniles and young adults. The effects of chronic sleep deprivation on anxiety-like behavior and cognitive function were evaluated in mice of different age groups, with findings suggesting that although similar behavioral outcomes were observed, the underlying molecular mechanisms may be different. Further research into the impact of sleep on mental health is warranted.

Summary: Evolutionary analysis of Prodiamesinae has been challenging due to lack of information, and its phylogenetic relationship with Orthocladiinae is still uncertain. However, this study sequenced ten complete mitogenomes of Orthocladiinae sensu lato, revealing conservation in gene arrangement and nucleotide composition, as well as protein-coding genes under purifying selection. The findings suggest a re-classification of Orthocladiinae by incorporating Prodiamesinae as a subgroup.

Summary: This study focused on species delimitation of five Leptocorisa species in China, especially the rice seed bugs complex. Genetic markers were used to distinguish between morphologically similar species, with nuclear SNP data proving to be effective in identifying separate species. Mitochondrial introgression resulting from hybridization was suggested as a likely explanation for mito-nuclear discordance between two taxa in the complex. This molecular evidence is crucial for further studies on the ecology and pest management of these important rice pests.

Summary: This study uses an integrative taxonomic approach to classify economically significant bean pests of the genus Chauliops. By employing morphological analyses, population genetic methods, and multiple molecular species delimitation methods, four new species are described, increasing the total number of Chauliops species in the area. Phylogenetic analysis and divergence time estimation reveal that speciation events in Chauliops are consistent with historical uplift events of the Qinghai-Tibet Plateau, suggesting that orogeny plays a key role in species diversification.

Summary: Studies have shown that spaceflight has emotional and social effects on astronauts. Identifying the neural mechanisms behind these effects is essential for targeted treatment and prevention. Repetitive transcranial magnetic stimulation (rTMS) has been found to improve neuronal excitability and treat psychiatric disorders like depression. In this study, the researchers investigated how rTMS affects the excitatory neuron activity in the medial prefrontal cortex (mPFC) in a simulated space complex environment (SSCE). They found that rTMS effectively improved the emotional and social impairments in mice exposed to SSCE, and enhanced the excitability of mPFC neurons. The study suggests that rTMS can reverse the mood and social impairment caused by SSCE by enhancing the suppressed mPFC excitatory neuronal activity.

Summary: Exploring new effective treatments for depression is of great social significance and clinical value. Low-intensity focused ultrasound stimulation (LIFUS) has been shown to have notable neuroprotective effects on depression, but little is known about how different strategies of LIFUS affect the therapeutic effect. The purpose of this study is to investigate the association between the effects of LIFUS on depression-like behaviors, intensity, and underlying mechanisms.
