Connecting brain to behaviour: a role for general purpose steering circuits in insect orientation?

摘要: The lateral accessory lobes (LALs), paired structures that are homologous among all insect species, have been well studied for their role in pheromone tracking silkmoths and phonotaxis crickets, where outputs shown to correlate with observed motor activity. Further studies more generally the LALs crucial both an insect's ability steer correctly organising of descending pathways towards centres. In this context, we propose a framework by which may be involved generating steering commands across variety insects behaviours. Across different behaviours, see LAL is two kinds steering: (1) search behaviours (2) targeted driven direct sensory information. Search generated when current behaviourally relevant cues not available, well-described subnetwork produces activity increases sampling environment. We that, integrate orientation information from several modalities, thus leading collective output those cues. These then sent centres, additional efference copy back orientation-computing areas. summary, taken known aspects neurophysiology function speculative suggests how might control complex real-world insects.
