The brain avoids pathological feedback loops through inhibitory neural circuits
Is it true that the brain avoids pathological feedback loops through inhibitory neural circuits?
Yes. Neurophysiological evidence consistently demonstrates that the brain maintains stable network dynamics and prevents runaway pathological feedback loops through the precise regulation and balance of excitatory and inhibitory neural circuits.
Verdict: SUPPORTED · 5 sources for, 0 against · Last checked
The retrieved papers consistently support the claim that the central nervous system utilizes an ongoing balance between excitation and inhibition to regulate network dynamics, prevent instability, and maintain physiological functioning.
