A neuroanatomical analysis of Rimicaris exoculata provides insights into these animal’s brain architecture to illustrate possible adaptations to the hydrothermal vent habitat with its extreme physicochemical conditions.
The substrate for evolutionary divergence does not lie in changes in neuronal cell number or targeting, but rather in sensory perception and synaptic partner choice within invariant, prepatterned neuronal processes.
Open source software enables neuroscientists to integrate single neuron or synaptic-resolution datasets from different imaging modalities to analyse morphology and connectivity at the scale of whole brains and connectomes.
The Drosophila lateral horn, a higher olfactory brain area, contains >165 genetically defined cell types with stereotyped odour responses across animals and improved odor categorisation compared with their inputs.
High-resolution fluorescence imaging of the complete mouse brain enables many neurons to be efficiently visualized in their entirety, revealing all targets of neurons that project widely across the brain.
A combination of genetic, anatomical and physiological techniques has revealed that the lateral horn, a region of the brain involved in olfaction in flies, has many more types of neurons than expected.
A complete connectome of the ON and OFF motion pathways of the Drosophila optic lobe is acquired using three-dimensional EM methods, and the similarities and differences of the two pathways are uncovered.
