The synaptic theory of plasticity

The synaptic theory of plasticity suggests that learning and memory happen by strengthening or weakening connections between nerve cells (neurons) at synapses, where they communicate. When we learn something new, the synapses involved become more efficient at passing signals, making it easier for neurons to activate together in the future. Conversely, if a connection isn’t used, it may weaken. This ability of synapses to change their strength in response to activity is essential for adapting our brain to new experiences and storing information effectively.
