An evaluation of the role of identified interneurons in triggering kicks and jumps in the locust

Abstract: 1. We have used intracellular recording and staining techniques to examine the importance of certain identified interneurons within the system responsible for triggering kicks and jumps in the locust, Locusta migratoria. In particular, our study focused on a pair of metathoracic interneurons called the M-neurons. These cells make strong inhibitory connections to hind-leg flexor motoneurons and are thought to play a key role in the termination of flexor activity which causes kicks and jumps to be triggered (8, … Show more

“…The time course of the decay in DCMD firing rate following its peak could contribute to it (Fotowat and Gabbiani, 2007). Other potential sources of variability include the DIMD, additional looming sensitive neurons, local interneurons, and sensory feedback (Pearson et al, 1980; Gynther and Pearson 1989; Jellema and Heitler, 1999). …”

“…17. Neuron 714 is one of several interneurons that provide multimodal outputs in the form of combined information from more than one sensory source and it is part of the neuronal chain that triggers jumping in locusts (Gynther and Peerson, 1989). The extensive range of both inputs and outputs to this neuron highlight its importance as a component of the locust nervous system and it is clearly a neuron which will repay deeper study in the future.…”

“…The probability of eliciting coactivation in response to arousal stimuli is itself controlled by at least three independent proprioceptive systems monitoring tibial position (Jellema et al,Fig. Both results indicate that M normally acts in concert with other elements of the circuit (Gynther and Pearson, 1989). M is inhibited concurrently with flexor motor activity.…”

“…M is silent, and normally slightly hyperpolarized, throughout the coactivation period, but produces a burst of spikes at the end of this period coinciding with the repolarization in the flexors and the subsequent kick (Fig. If M is induced to spike prematurely with injected current, then the kick is triggered prematurely, suggesting that the M spike burst is a major component of the trigger for the motor program (Gynther and Pearson, 1989). If M is induced to spike prematurely with injected current, then the kick is triggered prematurely, suggesting that the M spike burst is a major component of the trigger for the motor program (Gynther and Pearson, 1989).…”
