Meaning and Definition
A specific measure of the time required for electrical stimulation of a nerve or muscle cell, related to the minimum duration of an electrical pulse needed to excite the tissue.
In neurophysiology and physiology, it denotes the shortest time a current of twice the rheobasic strength needs to flow to stimulate a nerve or muscle fiber. It serves as a characteristic index of tissue excitability and is used in clinical and experimental contexts.

FAQ
Frequently Asked Questions
No, it is an extremely rare and specialised term used only in specific scientific and medical contexts.
Rheobase is the minimum current strength needed to excite a tissue with a theoretically infinite duration pulse. Chronaxie is the minimum time needed at twice the rheobase strength. They are two linked parameters defining tissue excitability.
It would be highly unusual and likely misunderstood, as it has no application in general discourse.
It is typically determined experimentally by applying electrical pulses of varying durations and intensities to a nerve or muscle preparation and finding the pulse duration required at twice the rheobase current.
A specific measure of the time required for electrical stimulation of a nerve or muscle cell, related to the minimum duration of an electrical pulse needed to excite the tissue.
Chronaxie is usually specialized technical / scientific in register.
Chronaxie: in British English it is pronounced /ˈkrɒnəksi/, and in American English it is pronounced /ˈkroʊnəksi/ or /ˈkrɑːnəksi/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of 'chrono-' (time) and 'axie' (sounds like 'axis' or relating to an axon). It's the 'time axis' needed to excite a nerve.
Conceptual Metaphor
THE EXCITABILITY OF A NERVE IS A RACE AGAINST TIME (a shorter chronaxie means the tissue is faster/more easily excited by a brief stimulus).
