Logarithmically scaled, gamma distributed neuronal spiking

D Levenstein, M Okun - The Journal of Physiology, 2023 - Wiley Online Library
Naturally log‐scaled quantities abound in the nervous system. Distributions of these
quantities have non‐intuitive properties, which have implications for data analysis and the …

[PDF][PDF] Preexisting hippocampal network dynamics constrain optogenetically induced place fields
