Biological System Fidelity

Meaning

Biological System Fidelity refers to the degree of accuracy, reliability, and precision with which a biological system, particularly the endocrine network, maintains its optimal function and responsiveness over time. High fidelity means the system accurately transmits and receives molecular signals, like hormones and neurotransmitters, without degradation or noise, ensuring precise cellular responses. Loss of fidelity, often seen with aging or chronic stress, manifests as reduced hormone receptor sensitivity and erratic signaling, contributing to systemic dysfunction.
