Excellent: coffee and learning

[…] administering caffeine to humans immediately after memory encoding enhances consolidation, as reflected by improved performance in a memory test a day later. And by the way:

Bard Ermentrout @ SCNS

Just saw the revered, enigmatic and highly energetic Bard Ermentrout at the SCNS at EPF Lausanne. Besides being quite revealing on his early life hobbies and their effects on his sensory apparatus, he gave a hard to follow but interesting talk on how to perform a dimensional reduction of noisy oscillator neuron models. We formulate a phase-reduction method for a general...

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...
