Structural plasticity and memory
WebThe modulation of structural plasticity by various experiential factors as well as the possible role it may have in hippocampal functions such as learning and memory, anxiety, and stress regulation are also considered. Although significant progress has been made in many of these areas, we highlight some of the outstanding issues that remain. WebFeb 8, 2024 · Brain plasticity, also known as neuroplasticity, is the biological, chemical, and physical capacity of the brain to reorganize its structure and function.
