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

Description

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]
