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.
Cerebellar functional regions follow a gradual organization, which progresses from primary (motor) to transmodal (Default Mode Network) regions, and a secondary axis extends from task-unfocused to task-focused processing.
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.
