An Endocrine Hypothesis of Brain Aging and Studies on Brain-Endocrine Correlations and Monosynaptic Neurophysiology during Aging a major role in mammalian aging. In particular, there seems to be a somewhat selective age-dependent deterioration of dopaminergic transmitter systems in rodents . and in humans .. Additionally, there is now some evidence that reduced dopaminergic presynaptic function is associated with reduced pos啜泣 发表于 2025-3-26 08:16:04
