Neuroplasticity through Hormones

Meaning

The modulation of the brain’s capacity for structural and functional reorganization—including synaptogenesis, dendritic branching, and neurogenesis—mediated by the action of circulating endocrine factors, notably steroid hormones and neuropeptides. Hormones such as estrogen, testosterone, and thyroid hormone act as powerful neurotrophic agents, directly influencing the molecular machinery of neuronal growth and synaptic transmission. This process highlights the endocrine system’s profound and direct regulatory role in maintaining cognitive health and facilitating brain repair.
