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.
An implantable device based on organic electrochemical transistors is developed for quantitative mapping of neurotransmitter release across multiple brain regions, revealing a cross-talk between the mesolimbic and nigrostriatal dopaminergic pathways.
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.
Functional UltraSound imaging allows mapping tonotopic organisation in multiple auditory subcortical and cortical brain structures with an unprecedented spatial functional resolution, while giving access to long-distance top-down connectivity pattern from frontal cortex to auditory cortex.
Differing from its ortholog in Helicoverpa armigera, pheromone receptor HassOr14b is tuned to the major sex pheromone component in H. assulta, and two amino acids in the intracellular domain determine their ligand selectivity.
