Tiny Insect Brains Capable of Huge Feats

14.06.2010
Insects may have tiny brains the size of a pinhead, but the latest research from the University of Adelaide shows just how clever they really are.

For the first time, researchers from the University’s Discipline of Physiology have worked out how insects judge the speed of moving objects.

It appears that insect brain cells have additional mechanisms which can calculate how to make a controlled landing on a flower or reach a food source. This ability only works in a natural setting.

In a paper published in the international journal Current Biology, lead author David O’Carroll says insects have well identified brain cells dedicated to analysing visual motion, which are very similar to humans.

“It was previously not understood how a tiny insect brain could use multiple brain pathways to judge motion,” Associate Professor O’Carroll says.

“We have known for many years that they can estimate the direction of moving objects but until now we have not known how they judge speed like other animals, including humans.

“It appears they take into account different light patterns in nature, such as a foggy morning or a sunny day, and their brain cells adapt accordingly.

“This mechanism in their brain enables them to distinguish moving objects in a wide variety of natural settings. It also highlights the fact that single neurons can exhibit extremely complex behaviour.”

Assoc. Prof. O’Carroll co-authored the paper with Paul Barnett, a Physiology PhD student at the University of Adelaide, and Dr Karin Nördstrom, a former Physiology Postdoctoral Fellow at Adelaide who is now based at Uppsala University in Sweden.

Their specific research is focused on how the brain makes sense of the world viewed by the eye, using the insect visual system as an important model.

“Insects are ideal for our research because their visual system accounts for as much as 30% of their mass, far more than most other animals,” Assoc. Prof. O’Carroll says.

His team is collaborating with industry to develop artificial eyes in robots, mimicking human and insect vision.

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
