The mapping of visual space by identified large second-order neurons in the dragonfly media ocellus

Berry, Richard; Stange, Gert; Olberg, Robert; Van Kleef, Joshua


In adult dragonflies, the compound eyes are augmented by three simple eyes known as the dorsal ocelli. The outputs of ocellar photoreceptors converge on relatively few second-order neurons with large axonal diameters (L-neurons). We determine L-neuron morphology by iontophoretic dye injection combined with three-dimensional reconstructions. Using intracellular recording and white noise analysis, we also determine the physiological receptive fields of the L-neurons, in order to identify the...[Show more]
