Every time you learn something new, the strength of specific synaptic connections between the neurons handling that memory is physically enhanced. BDNF facilitates this as a growth factor protein concentrated in learning-critical regions like the hippocampus. Synaptic plasticity isn't a metaphor for learning — it's the literal hardware mechanism, and BDNF is one of its chief enablers.
