From article:

> Cause and Effect: If Neuron A fires just a few milliseconds before Neuron B, the brain assumes A caused B. The synapse between them gets stronger.

A recent study from Stanford found that it's more complex than this rule, some synapses followed it, some did the opposite, etc.

Non-Hebbian and Anti-Hebbian potentiation have been well studied for decades. Anti-Hebbian notably for inhibitory connections.
