An increasing number of studies indicate that the modulation effect of acupuncture on intracerebral neural circuits is a crucial pathway through which acupuncture exerts its therapeutic effects. Among these, brain region activation, functional connectivity, and synaptic transmission collectively form the three dimensions of acupuncture modulation of neural circuits. Brain region activation reflects the activity state of key nodes in neural circuits, functional connectivity focuses on the intensity and patterns of information exchange within neural circuits, and snaptic transmission examines molecular-level changes during signal projection in neural circuits. To systematically elucidate the mechanisms of acupuncture, this paper first analyzed the impact of acupuncture on these three dimensions using commonly used points such as Quchi (LI11) as examples. Then, it explored the multi-dimensional regulatory effects of acupuncture on neural circuits related to clinically advantageous conditions like pain, mood disorders, and gastrointestinal dysfunction. Finally, it proposed issues and potential solutions for the multi-dimensional analysis of acupuncture-related neural circuits, aiming to provide insights for advancing research on acupuncture mechanisms and guiding further precision treatment.

Significance: The spatial and temporal distribution of fluorophore fractions in biological and environmental systems contains valuable information about the interactions and dynamics of these systems. To access this information, fluorophore fractions are commonly determined by means of their fluorescence emission spectrum (ES) or lifetime (LT). Combining both dimensions in temporal-spectral multiplexed data enables more accurate fraction determination while requiring advanced and fast analysis methods to handle the increased data complexity and size.

Neuronal networks in animal brains are considered to realize specific filter functions through the precise configuration of synaptic weights, which are autonomously regulated without external supervision. In this study, we employ a single Hodgkin-Huxley-type neuron with autapses as a minimum model to computationally investigate how spike-timing-dependent plasticity (STDP) adjusts synaptic weights through recurrent feedback. The results show that the weights undergo oscillatory potentiation or depression with respect to autaptic delay and high-frequency stimulation.

Neural circuits sculpt their structure and modify the strength of their connections to effectively adapt to the external stimuli throughout life. In response to practice and experience, the brain learns to distinguish previously undetectable stimulus features recurring in the external environment. The unconscious acquisition of improved perceptual abilities falls into a form of implicit learning known as perceptual learning.

Introduction: Understanding how neural networks process complex patterns of information is crucial for advancing both neuroscience and artificial intelligence. To investigate fundamental principles of neural computation, we examined whether dissociated neuronal cultures, one of the most primitive living neural networks, exhibit regularity sensitivity beyond mere stimulus-specific adaptation and deviance detection.
Methods: We recorded activity to oddball electrical stimulation paradigms from dissociated rat cortical neurons cultured on high-resolution CMOS microelectrode arrays.

Objectives: To investigate the role of a neural pathway from oxytocin (OXT) neurons in the hypothalamic paraventricular nucleus (PVN) to γ-aminobutyric acid (GABA) neurons in the trigeminal nucleus caudalis (TNC) in regulating pain sensitization in a mouse model of chronic migraine and to explore the underlying mechanisms.
Methods: A chronic migraine model was established by intraperitoneal injection of nitroglycerin (NTG, 10 mg/kg) on days 1, 3, 5, 7, and 9. The study consisted of four parts: PartⅠ: Wild-type C57BL/6J mice were divided into 4 groups (=6 in each), receiving single or repeated injection of NTG or saline, respectively.
