Inspired by the critical brain hypothesis, which proposes that the brain operates optimally near a critical point of phase transition in the dynamics of neural networks to improve computational efficiency, we postulate that spontaneous activity plays a homeostatic role in the development and maintenance of criticality. Criticality in the brain is associated with the balance between excitatory and inhibitory synaptic inputs (EI balance), which is essential for maintaining neural computation performance. Here, we hypothesize that both criticality and EI balance are stabilized by appropriate noise levels and spike-timing-dependent plasticity (STDP) windows. Using spiking neural network (SNN) simulations and <i>in vitro</i> experiments with dissociated neuronal cultures, we demonstrated that while repetitive stimuli transiently disrupt both criticality and EI balance, spontaneous activity can develop and maintain these properties and prolong the fading memory of past stimuli. Our findings suggest that the brain may achieve self-optimization and memory consolidation as emergent functions of noise-driven spontaneous activity. This noise-harnessing mechanism provides insights for designing energy-efficient neural networks, and suggest a potential link between the emergent function of spontaneous activity and sleep function in maintaining homeostasis and consolidating memory.</p>","PeriodicalId":12498,"journal":{"name":"Frontiers in Neural Circuits","volume":"19 ","pages":"1585087"},"PeriodicalIF":2.9,"publicationDate":"2025-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12589027/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145481583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nine dendrites and all presynaptic boutons (<i>n</i> = 815) impinging on their surface were traced and reconstructed in three-dimensions (3D) using serial section transmission electron microscopy (ssTEM). The following basic parameters of the synapses were determined: The ratio of symmetric (\"ss\" or putative inhibitory) and asymmetric (\"as\" or putative excitatory) synapses, the number of synapses per unit length of dendrite (i.e., density of \"as\" and \"ss\"), surface area and volume of presynaptic boutons, and area of the active zones of synapses. Significant differences in the morphometric parameters of asymmetric, but not in symmetric, synapses were detected between the three interneuron subtypes. Surface extent and the number of synapses on PV+ dendrites were the largest compared to the other two subtypes. Although the distribution of presynaptic boutons differed between dendrites, clustering of the presynaptic boutons could be revealed only for PV+ dendrites.

According to the prevailing views, cortical strategy is to choose features that exhibit predictable relationship to their spatial and/or temporal context. Such contextually predictable features likely make explicit the causal factors operating in the environment and thus they are likely to have perceptual/behavioral utility. The known details of functional architecture of cortical columns suggest that cortical extraction of such features is a modular nonlinear operation, in which the input layer, layer 4, performs initial nonlinear input transform generating proto-features, followed by their linear integration into output features by the basal dendrites of pyramidal cells in the upper layers. Tuning of pyramidal cells to contextually predictable features is guided by the contextual inputs their apical dendrites receive from other cortical columns via long-range horizontal or feedback connections. Our implementation of this strategy in a model of prototypical V1 cortical column, trained on natural images, reveals the presence of a limited number of contextually predictable orthogonal basis features in the image patterns appearing in the column's receptive field. Upper-layer cells generate an overcomplete Hadamard-like representation of these basis features: i.e., each cell carries information about all basis features, but with each basis feature contributing either positively or negatively in the pattern unique to that cell. In tuning selectively to contextually predictable features, upper layers perform selective filtering of the information they receive from layer 4, emphasizing information about orderly aspects of the sensed environment and downplaying local, likely to be insignificant or distracting, information. Altogether, the upper-layer output preserves fine discrimination capabilities while acquiring novel higher-order categorization abilities to cluster together input patterns that are different but, in some way, environmentally related. We find that to be fully effective, our feature tuning operation requires collective participation of cells across 7 minicolumns, together making up a functionally defined 150 μm diameter \"mesocolumn.\" Similarly to real V1 cortex, 80% of model upper-layer cells acquire complex-cell receptive field properties while 20% acquire simple-cell properties. Overall, the design of the model and its emergent properties are fully consistent with the known properties of cortical organization. Thus, in conclusion, our feature-extracting circuit might capture the core operation performed by cortical columns in their feedforward extraction of perceptually and behaviorally significant information.</p>","PeriodicalId":12498,"journal":{"name":"Frontiers in Neural Circuits","volume":"19 ","pages":"1615232"},"PeriodicalIF":3.0,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12537795/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145344827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the other hand, pyramidal neurons tend to fire slightly faster than the theta oscillation in what is termed hippocampal phase precession. Chimera states are specific solutions to dynamical systems where synchrony and asynchrony coexist, similar to coexistence of phase precessing and phase locked cells during the hippocampal theta oscillation. Here, we test the hypothesis that the hippocampal phase precession emerges from chimera dynamics with computational modeling. We utilized multiple network topologies and sizes of Kuramoto oscillator networks that are known to collectively display chimera dynamics. We found that by changing the oscillators' intrinsic frequency, the frequency ratio between the synchronized and unsynchronized oscillators can match the frequency ratio between the hippocampal theta oscillation (≈ 8 Hz) and phase precessing pyramidal neurons (≈ 9 Hz). The faster firing population of oscillators also displays theta-sequence-like behavior and phase precession.

It contributes to various aspects of voluntary movement, such as locomotion, gait, coordination, and muscle contractions. It also contributes to involuntary motor behavior (i.e., spasms), which affects many individuals with spinal cord injury. Despite its known involvement in motor function, additional research in uninjured mice is required to assess whether specific gait parameters and muscle contractility are directly linked to the 5-HT_2C receptor. In injured mice, further research is needed to determine whether the expression of the 5-HT_2C receptor is altered in the lumbar and sacral spinal cord after injury. It is also necessary to determine whether voluntary locomotion, involuntary motor behavior, or the expression of this receptor is influenced by sex, as it is unknown if there is a difference in 5-HT_2C receptor expression between male and female mice. The aim of this study is to investigate volitional and involuntary motor behavior of male and female uninjured and spinal cord-injured knock-out mice. Mice that express a non-functional form of the 5-HT_2C receptor were compared to typical-functioning wildtype mice. Volitional behavioral assessments revealed mild strength and stability deficits in the knock-out mice when compared to wildtype mice. We also compared the capacity of spinal cord tissue to generate sensory evoked activity, and it was revealed that male knock-out mice exhibited less involuntary motor behavior both <i>ex vivo</i> and <i>in vivo</i> than male wildtype mice. Western blot analysis revealed that injury status, sex, and genotype affected the relative expression of the 5-HT_2C receptor in both the lumbar and sacral spinal cord, with female KO mice exhibiting a compensatory mechanism post-SCI via upregulation of the 5-HT_2A receptor. Through a comprehensive approach combining behavioral assessments, electrophysiological experiments, and whole-tissue protein analysis, our findings provide strong evidence that the 5-HT_2C receptor is differentially regulated by sex, genotype, and spinal cord injury. These findings underscore the importance of considering sex as a biological variable and suggest that future therapeutic strategies targeting the 5-HT_2C receptor account for sex-specific differences in 5-HT_2C receptor expression and function.</p>","PeriodicalId":12498,"journal":{"name":"Frontiers in Neural Circuits","volume":"19 ","pages":"1681120"},"PeriodicalIF":3.0,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12515959/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145291808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tau aggregates had little effect on basal synaptic transmission but antagonism of GABA_A receptors revealed significant effects of tau aggregates, enhancing the firing of population spikes and the occurrence of bursts following fEPSPs. Tau aggregates produced a concentration-dependent impairment of long-term potentiation (LTP), which could not be overcome by repeated LTP induction stimuli, demonstrating the effects were not just through an elevation of LTP threshold.

Here, we conducted wide-field calcium imaging and revealed retinotopic and somatotopic correspondence in the rostrolateral area (RL), one of the higher visual areas.

We discovered that the topographical correspondence between retinotopy-like and somatotopy-like structures in RLa already existed before eye-opening, on postnatal day 10-11.
