How stem cells produce the huge diversity of neurons that form the visual system, and how
these cells are assembled in neural circuits are a critical question in developmental …

Animal behaviour arises from computations in neuronal circuits, but our understanding of
these computations has been frustrated by the lack of detailed synaptic connection maps, or …

In the eye, visual information is segregated into modalities such as color and motion, these
being transferred to the central brain through separate channels. Here, we genetically …

In insects, visual information is processed in the optic lobe and conveyed to the central
brain. Although neural circuits within the optic lobe have been studied extensively, relatively …

Background In the fly's visual motion pathways, two cell types—T4 and T5—are the first
known relay neurons to signal small-field direction-selective motion responses [1]. These …

Motion vision is essential for navigating through the environment. Due to its genetic
amenability, the fruit fly Drosophila has been serving for a lengthy period as a model …

In malacostracan crustaceans and insects three nested optic lobe neuropils are linked by
two successive chiasmata that reverse and then reverse again horizontal rows of retinotopic …

We present a computational model for target discrimination based on intracellular
recordings from neurons in the fly visual system. Determining how insects detect and track …

Acetylcholine is the major excitatory neurotransmitter in the central nervous system of
insects. Mutant analysis of the Dα7 nicotinic acetylcholine receptor (nAChR) of Drosophila …

Synaptic connections of neurons in the Drosophila lamina, the most peripheral synaptic
region of the visual system, have been comprehensively described. Although the lamina has …
