Abstract Mammalian voltage‐gated calcium channels (Ca V ) play critical roles in cardiac excitability, synaptic transmission, and gene transcription. Dysfunctions Ca are implicated a variety of neurodevelopmental disorders. Current pharmacological approaches to enhance activity limited by off‐target effects, drug metabolism issues, cytotoxicity, imprecise modulation. Additionally, genetically‐encoded channel activators optogenetic tools restricted delivery challenges biosafety concerns. Here novel terahertz (THz) wave‐based method upregulate 1.2, key subtype , boost 1‐mediated 2+ signaling neurons without introducing exogenous DNA is presented. Using molecular dynamics simulations, it shown that 42.5 THz (7.05 µm, 1418 cm −1 waves conductance 1.2 resonating with the stretching mode ‐COO − group selectivity filter. Electrophysiological recordings imaging confirm these rapidly, reversibly, non‐thermally increase influx HEK293 cells induce acute signals neurons. Furthermore, this irradiation upregulates 1 signals, including CREB phosphorylation c‐Fos expression, vitro vivo, raising significant risks. This DNA‐free, non‐invasive approach offers promising for modulating gating treating diseases characterized deficits functions.

Comorbid anxiety in chronic pain is clinically common, with a comorbidity rate of over 50%. The main treatments are based on pharmacological, interventional, and implantable approaches, which have limited efficacy carry risk side effects. Here, we report terahertz (THz, 10 12 Hz) wave stimulation (THS) technique, exerts nonthermal, long-term modulatory effects neuronal activity by reducing the binding between nano-sized glutamate molecules GluA2, leading to relief comorbid anxiety-like behaviors mice. In mice co-occurring induced complete Freund’s adjuvant (CFA) injection, hyperactivity was observed glutamatergic neurons anterior cingulate cortex (ACC Glu ). Using whole-cell recording ACC slices, demonstrated that THS (34 THz) effectively inhibited excitability . Moreover, molecular dynamics simulations showed reduced number hydrogen bonds bound GluA2. Furthermore, target CFA-treatment suppressed and, as result, alleviated behaviors. Consistently, inhibition chemogenetics mimics THS-induced antinociceptive antianxiety behavior. Together, our study provides evidence for an intervention technique modulating viable clinical treatment strategy anxiety.

Abstract Neurite outgrowth and synapse formation constitute the cellular basis for establishment plasticity of neural networks, crucially involved in cognitive functions. However, techniques currently available to effectively specifically modulate these processes remain limited. In this work, we propose a non-drug non-thermal terahertz (THz) photon modulation approach that enhances neuronal growth synaptogenesis. Frequency screening experiments show 34.5 THz stimulation could promote neurite elongation postsynaptic density protein 95 (PSD95) expression by 26.0% rat hippocampal neurons. Subsequent reveal an upregulation cyclic adenosine monophosphate (cAMP) signaling pathway adenylyl cyclase type 1 (AC1) activity after irradiation. Molecular dynamics simulations suggest photons binding between AC1 ligand, accelerating cAMP generation. vivo further confirm increase levels dendritic spine stimulation, accompanied significant improvement performance. Overall, our results as effective specific method neuromodulation, promising future applications treatment dysfunction.
