thermoreception in polar bears — Thermoreception Warm-blooded animals, such as polar bears, maintain stable body temperatures and adapt to substantial geographic and seasonal temperature fluctuations. Thermal adaptation is supported by the function of sensory structures called thermoreceptors.

In the cockroach Periplaneta americana, cold receptors located on the antennae maintain continuous activity at constant temperatures.1

The physiological response to temperature changes is as follows:

Rapid cooling: The receptor's discharge frequency increases steeply before gradually declining to a lower, constant level.1
Rapid warming: The receptor exhibits the opposite response, characterized by a decrease in discharge frequency.1

These receptors are housed within delicate, hairlike structures known as sensilla, which are mechanically protected by larger bristles on the antennal segments.1
