Tonic Receptors

Definition

Specialized sensory receptors that continuously fire at a low rate, even when the stimulus is constant. These receptors are important for monitoring stimulus intensity over time and detecting persistent stimuli.

Etymology

From Latin 'tonicus', from Greek 'tonikos', meaning 'pertaining to tension'.

Example

Tonic receptors in the antennae of insects help them detect continuous environmental changes such as wind direction.
