The hippocampus is the only known brain region where physiological neurogenesis continues into adulthood across mammalian species and in humans. However, disease and injury can change the level of adult hippocampal neurogenesis, which plays an important role in regulating cognitive and emotional abilities. Alterations in hippocampal neurogenesis can mediate treatment of mental illness or affect the brain's capacity for repair and regeneration. In the present review, we evaluate how adult neurogenesis contributes to the repair and regeneration of hippocampal circuitry in the face of diseases and injuries. We also discuss possible future directions for harnessing adult neurogenesis for therapeutic use.

The large majority of Alzheimer's disease (AD) cases are sporadic with unknown genetic causes. In contrast, only a small percentage of AD cases are familial, with known genetic causes. Paradoxically, there are only few validated mouse models of sporadic AD but many of familial AD.

The phosphatase and tensin homolog deleted on chromosome 10 (PTEN) gene is a critical tumor suppressor that plays an essential role in the development and functionality of the central nervous system. Located on chromosome 10 in humans and chromosome 19 in mice, PTEN encodes a protein that regulates cellular processes such as division, proliferation, growth, and survival by antagonizing the PI3K‑Akt‑mTOR signaling pathway. In neurons, PTEN dephosphorylates phosphatidylinositol‑3,4,5‑trisphosphate (PIP3) to PIP2, thereby modulating key signaling cascades involved in neurogenesis, neuronal migration, and synaptic plasticity.

Background And Objectives: Depression long been a key concern for scholars worldwide; however, the field of depression has not received sufficient attention in traditional Chinese medicine. It was not until the 21st century that research into depression gradually entered a period of rapid development, with an increasing number of academic studies published in major journals. However, one limitation of this field is that no scholars have yet summarised the development process and key research issues.

Purpose: A comprehensive literature review was undertaken to understand the effects and underlying mechanisms of cranial radiotherapy (RT) on the hippocampus and hippocampal neurogenesis as well as to explore protective factors and treatments that might mitigate these effects in preclinical studies.
Methods: PubMed/MEDLINE, Web of Science, and Embase were queried for studies involving the effects of radiation on the hippocampus and hippocampal neurogenesis. Data extraction followed the Animal Research Reporting of In Vivo Experiments (ARRIVE) guidelines, and a risk of bias assessment was conducted for the included animal studies using the Systematic Review Centre for Laboratory Animal Experimentation (SYRCLE) risk of bias tool.

Introduction: Intermittent fasting (IF) has emerged as a potential lifestyle intervention for mitigating cognitive decline and enhancing brain health in individuals with mild to major neurocognitive disorders. Unlike preventive strategies, this review evaluates IF as a therapeutic approach, focusing on its effects on neuroplasticity, inflammation, and cognitive function.
Methods: A narrative review was conducted using a comprehensive PubMed search with the terms "intermittent fasting AND neurocognition" and "intermittent fasting AND neuroplasticity".
