Brain tissue is vulnerable to temperature changes, which are known to affect the structure and function of neural circuits. Owing to their dynamic ramified processes, microglia, which serve as immune cells in the brain, are associated with surveillance of the brain environment and mediate synaptic pruning to reorganize neural circuits. In this section, we discuss the possible role of microglia as temperature sensors in the brain via thermosensitive transient receptor potential channels and their role in reorganization of neural circuits.

Pain is a dynamic and nonlinear experience shaped by injury and contextual factors, including expectations of future pain or relief . While µ opioid receptors are central to the analgesic effects of opioid drugs, the endogenous opioid neurocircuitry underlying pain and placebo analgesia remains poorly understood. The ventrolateral column of the posterior periaqueductal gray is a critical hub for nociception and endogenous analgesia mediated by opioid signaling .

Previous studies have demonstrated that one dose of psilocybin leads to persisting neural and behavioral changes. The durability of psilocybin's effects suggests that there are likely alterations of gene expression at the transcriptional level.

This leads to a state of relative inhibition, reducing feedforward gamma (40-90 Hz) rhythms and spiking to predictable inputs. We refer to this model as predictive routing.

Astrocytes are the primary cell type in the central nervous system, responsible for maintaining the stability of the brain's internal environment and supporting neuronal functions. Researches have demonstrated the close relationship between astrocytes and the pathophysiology and etiology of major depressive disorder. However, the regulatory mechanisms of astrocytes during depression remain unclear.

Spinal cord injury (SCI) remains a significant clinical challenge, with no fully effective treatment available despite advancements in various therapeutic approaches. This review examines the emerging role of induced neural stem cells (iNSCs) as promising candidates for SCI treatment, highlighting their potential for direct neural regeneration and integration with host tissue. We explore the biology of iNSCs, their mechanisms of action, and their interactions with host tissue, including modulating inflammatory responses, promoting axonal growth, and reconstructing neural circuits.
