LNs in hatchlings and adults respond similarly to odors. Representative examples of membrane potentials of LNs in hatchling and adult locusts responding to 1 s odor pulses (black bar). Each trace is from a different LN. Locust LNs do not produce action potentials, but rather calcium spikelets, the rate of which may change upon odor presentation. LNs membrane potential can also oscillate, depolarize, hyperpolarize, or undergo a mixture of these. LNs in locusts of both age groups show similar responses. Scale bars: 10 mV.
