Why does long-term potentiation strengthen synaptic connections during sleep?

A)Cortisol inhibits neuronal excitability
B)GABA reduces brain activity globally
C)Slow waves synchronize neural firing
D)Melatonin suppresses protein synthesis

💡 Explanation

Slow wave sleep facilitates memory consolidation because slow waves synchronize neural firing, enhancing long-term potentiation, which strengthens synaptic connections. Therefore, memories are reinforced rather than being degraded due to a lack of coordinated activity or hormonal inhibition.
