On the left-side bias of brain depictions

As demonstrated recently at SFN by Wilson et al., there is a clear left-hemisphere bias of brain depictions. […] An argument based on the prevalence of right-handed illustrators cannot explain the bias seen in photographs of the brain. Some colleagues have suggested that the bias reflects the left-to-right nature of English writing, but we find this argument less than compelling, especially given...

Multi-odor evoked ensemble dynamics

Extending on the milestone paper by Mazor & Laurent, this recently published study by Saha et al. investigates the antennal lobe dynamical odor representations that are evoked by adding a second odor stimulus on top of a background ongoing odor stimulus. Ensemble interference and partial overlaps ensue AND they correlate nicely with locust behavior. Main article @ Nature Neuro This is...

Neuromorphic hardware growing up?

In this study scientists from ETH in Zurich have constructed a robotic goal keeper using an asynchronous silicon retina. Similar to a frog’s eye the retina chip detects fast changes in the visual input and sends these as singular events via USB to a computer. Quick movement of an incoming ball entails a lot of such events which facilitates the...

The Thatcher Effect

The Thatcher Effect, it confuses the hell out of me. This is thought to be due to specific psychological cognitive modules involved in face perception which are tuned especially to upright faces.

Your episodic memory is probably distorted

http://www.pnas.org/content/early/2013/11/12/1314373110.abstract The findings suggest that HSAM individuals reconstruct their memories using associative grouping, as demonstrated by a word-list task, and by incorporating postevent information, as shown in misinformation tasks. The findings also suggest that the reconstructive memory mechanisms that produce memory distortions are basic and widespread in humans, and it may be unlikely that anyone is immune. NO ONE IS...

Evolution is power-law

I heard an interesting talk at the Salk institute today by Richard E. Lenski about time travel in evolution. What they did over the last 25 years or so is to track over generations a strand of E. coli bacteria. Going back in time means taking out a batch from the freezer while going forward in time means just letting...

Out now

Out now with probably the best timing with respect to the end of SfN. I have not looked at it in detail but also the Figures seem to have the right widths. A rare thing in PLoS of late. Synaptic Plasticity in Neural Networks Needs Homeostasis with a Fast Rate Detector
