Here, the authors show that the activity of BF glutamatergic neurons decreased during the induction of isoflurane anesthesia and restored during the emergence in mice. Optogenetic activation of BF glutamatergic neurons accelerated the emergence from isoflurane anesthesia, decreased isoflurane sensitivity, and increased arousal score of mice. Moreover, optogenetic activation of BF glutamatergic neurons decreased EEG delta power and burst-suppression ratio, while increased pupil size and respiration rate of mice during isoflurane anesthesia. Similar results were observed during the optogenetic activation of BF glutamatergic terminals in the ventral tegmental area (VTA). Additionally, the authors found that the activity of BF glutamatergic neurons and VTA glutamatergic neurons synchronously fluctuate during isoflurane anesthesia, and optogenetic activation of BF glutamatergic terminals in the VTA potently increased the calcium signals of VTA glutamatergic neurons during isoflurane anesthesia. Collectively, their study illustrated that BF glutamatergic neurons promote isoflurane anesthesia emergence via activating VTA glutamatergic neurons. Both male and female mice were used in this study.Statement of Significance General anesthesia is widely used in modern medicine; however, its specific neural mechanisms remain poorly understood. The basal forebrain (BF) is a critical component of the ascending arousal system, and its glutamatergic neurons were implicated in sleep-wake behavior and cortical activity. Here, we report that optogenetic activation of BF glutamatergic neurons significantly promoted cortical activation, behavioral emergence and physiological indicators in mice under isoflurane anesthesia. Photostimulation of BF glutamatergic terminals in the ventral tegmental area (VTA) produced similar effects, and significantly increased the activity of VTA glutamatergic neurons. Our findings illustrated that BF glutamatergic neurons promote emergence from isoflurane anesthesia via VTA glutamatergic neurons, highlighting a potential target for attenuating anesthesia depth and accelerating anesthesia emergence in clinical anesthesia.","PeriodicalId":50114,"journal":{"name":"Journal of Neuroscience","volume":"48 1","pages":""},"PeriodicalIF":5.3,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144504622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These findings beg the question: What is the linking mechanism between sulcal morphology and cognition? Here, we investigated functional connectivity among sulci in LPFC and the lateral parietal cortex in participants drawn from the same sample as our previous study.

We conducted clustering and classification analyses of individual-level functional connectivity among sulci. Broadly, we found that (1) connectivity patterns of individual sulci could be differentiated and more accurately than cortical patches equated for size and shape; (2) sulcal connectivity did not consistently correspond with that of probabilistic labels or large-scale networks; (3) sulci clustered based on connectivity patterns, not dictated by spatial proximity; and (4) across individuals, greater depth was associated with higher network centrality for several sulci under investigation.

Accordingly, abrupt transitions in the state of cortical neurons-a phenomenon known as Up-Down states (UDS)-have been attributed to variation in the activity of afferent neurons. However, cellular physiology and morphology may also play a role in causing UDS. This study examines the impact of dendritic nonlinearities, particularly those mediated by voltage-dependent NMDA receptors, on the response of cortical neurons to balanced excitatory/inhibitory synaptic inputs. Using a neuron model with two segregated dendritic compartments, we compared cells with and without dendritic nonlinearities. NMDA receptors boosted somatic firing in the balanced condition and increased the correlation between membrane potentials across the compartments of the neuron model. Dendritic nonlinearities elicited strong bimodality in the distribution of the somatic potential when the cell was driven with cortical-like input. Moreover, dendritic nonlinearities could detect small input fluctuations and lead to UDS whose statistics and dynamics closely resemble electrophysiological data. UDS also occurred in recurrent networks with oscillatory firing activity, as in anaesthetized animal models, when dendritic NMDA receptors were partially disabled. These findings suggest that there is a dissociation between cellular and network-level features that could both contribute to the emergence of UDS.
