Neurons maintain a specific minimum constant firing rate

The claim states that neurons maintain a specific *minimum constant* firing rate. The retrieved papers discuss 'firing rate homeostasis' (papers [0], [4], [7]), which means neurons regulate activity toward a baseline or set point over time, but they do so dynamically rather than maintaining a static, constant rate. In fact, papers [2] and [9] explicitly demonstrate that firing rates naturally fluctuate significantly in vivo based on stimuli, state changes, and task demands. Thus, while homeostatic regulation exists, the idea of a fixed constant rate is contested by continuous natural variability.
