Final answer:
Protein Kinase Mæ (PKMæ) is crucial for the maintenance of long-term memory and synaptic plasticity.
Step-by-step explanation:
Protein Kinase Mæ (PKMæ) is crucial for the maintenance of long-term memory and synaptic plasticity. It plays a key role in the signaling pathways that regulate the strength of connections between neurons, helping to form and maintain memories. When PKMæ is activated, it contributes to the strengthening of synapses and the consolidation of memories.
