The Aplysia Model

The Aplysia model uses a sea slug, Aplysia, to study how nervous systems learn and adapt. Its simple nerve cells and accessible neural circuits make it easier to observe and understand the basic processes behind learning, memory, and skin reflexes. By examining how these neurons change with experience, researchers gain insights into the fundamental mechanisms of neural plasticity that also apply to more complex brains, including humans. This model helps scientists understand how experiences can strengthen or weaken neural connections, which is essential for learning and behavioral adaptation.
