Mechanism: Human aging leads to a decline in synaptic plasticity and homeostatic mechanisms, impairing cognitive function. Readout: Readout: Bowhead whales maintain high synaptic health, an active homeostasis bot, and superior cognition over a 200+ year lifespan.

Humans lose cognitive function even while most neurons survive. Bowhead whales maintain cognition over 200 years. The difference may not be in preventing neuronal death, but in preserving synaptic plasticity and homeostatic mechanisms that mammals gradually lose.
