Mayer wave central tendency in different species.

Species	Mayer Wave Central Frequency
Rats	∼0.4 Hz
Rabbits	∼0.3 Hz
Cats	∼0.1 Hz
Dogs	∼0.1 Hz
Humans	∼0.1 Hz
Mice	Unknown

Traube–Hering central tendency corresponds with the frequency of the breathing impulse. Very low frequency oscillation central tendency corresponds with the frequency of the vasogenic autorhythmicity, typically cited to range between 0.025 and 0.075 Hz, though 0.01–0.1 Hz may represent a more inclusive, though les specific, range.
