Locusts are capable of performing complicated flying maneuvers, which relies on rapid detection of moving objects present in the surroundings to generate appropriate behavioural responses. An identified neural pathway, comprised of the LGMD (lobula giant motion detector) and the DCMD (descending contralateral motion detector), responds preferentially to approaching objects. LGMD receives retinotopic inputs from ipsilateral ommatidia and generates spikes in a 1:1 ratio in the DCMD, which synapses with multiple locomotion-related neurons. As an angular threshold detector, the DCMD has been implicated as critical for initiating evasive behaviours, although its specific role remains to be fully described. Importantly, numerous other motion-sensitive neurons have also been identified in locusts. These neurons have distinct firing properties and response preferences. Information from these neurons likely contributes to production of avoidance behaviour. However, few studies have investigated the contribution of these neurons on a neural population level. To better understand how visual information is perceived by locusts, we constructed a multichannel recording system within an existing flight simulator and presented various complex visual stimuli to rigidly tethered locusts. Preliminary analyses have identified functional units that responded to visual stimuli. Common trends, which reflect the activity of neural ensembles, were extracted from these functional units. These common trends were compared under different conditions to reveal how is the population coding is modulated dynamically.
