"The innexin 7 gap junction protein contributes to synchronized activity in the Drosophila antennal lobe and regulates olfactory function"
🥳🍾🔬🧪🧬🎉🎊

In the mammalian olfactory bulb (OB), gap junctions coordinate synchronous activity among mitral and tufted cells to process olfactory information. In insects, gap junctions are also present in the antennal lobe (AL), a structure homologous to the mammalian OB. The invertebrate gap junction protein....

Reelin is a secreted glycoprotein with roles in the development of the mammalian hippocampus and cerebral cortex. This vertebrate signaling molecule also contributes to adult brain function. Mammalian Reelin increases the complexity of Drosophila Mushroom Body (MB) neurites, an effect mediated by Lp...

Neural circuits for goal-directed navigation across species
‘
The hippocampus of vertebrates and the central complex of insects are both engaged by navigational tasks that require spatial memory or inference.

The hippocampus builds flexible place maps of both real and abstract spaces.

The insect central complex comprises ordered arrays of cells that are well suited to encode and compute with vectors. Both the hippocampus and central complex feature heading-direction signals based on ring attractor networks, and both structures receive input from partially segregated 'where' and 'what' pathways.

Current understanding of the differences between vertebrate and invertebrate navigational systems might reflect ecological, historical, and methodological differences.

Future comparative approaches will help to reveal fundamental relationships between brain circuits and navigational and cognitive abilities across species.

A parasitic fungus compels its insect host to behave in strange ways by hijacking secretory neurons and circadian pathways.
