Article Title: Localized and Long-Lasting Adaptation in Dragonfly Target-Detecting Neurons
doi: 10.1523/ENEURO.0036-24.2024
Figure Lengend Snippet: Dragonfly STMD neurons exhibit strong adaptation to a short-interval repetitive stimulus. A , In vivo, extracellular techniques permitted long-lasting recordings of STMDs. B , Pictogram illustrates mapping of the receptive field by presenting a series of small, dark targets drifting rightward (23 elevations vertically separated by 1.09°). C , Four example traces at central locations of the STMD receptive field (black bar when target was on screen). D , Colormap generated from the binned responses reveals STMD activity corresponding to target location across the visual field. E , Pictogram illustrates the adapting stimulus consisting of a repeating drifting small dark target within the excitatory receptive field. F , Example responses of three consecutive trials at 60.5 s intervals to targets presented at the adapting location (50°/s for 25°). G , Three consecutive trials at 10.5 s intervals reveal stronger neuronal adaptation.
Article Snippet: Extracellular probes (tungsten wire stereotrodes, 1 MΩ, World Precision Instruments, part # TST33C10KTH) were inserted into the ipsilateral lobula complex using an electronic micromanipulator (Sensapex UMTSC) mounted on a manual micromanipulator (WPI M3301R).
