10 Cognitive Distortions to be aware of

An Efficient Method for online Detection of Polychronous Patterns in Spiking Neural Network
Polychronous neural groups are effective structures for the recognition of precise spike-timing patterns but the detection method is an inefficient multi-stage brute force process that works off-line on pre-recorded simulation data. This work presents a new model of polychronous patterns that can capture precise sequences of spikes directly in the neural simulation.

Pupil size behavior during on line processing of sentences
In the present work we analyzed the pupil size behavior of forty subjects while they read well defined sentences with different contextual predictability (i.e., regular sentences and proverbs).

You need more DEET to stop old mosquitoes with Zika
If you’re traveling to, or living in, a Zika virus-infested area, a new study offers guidelines for using mosquito repellant. It’s far better to use the mosquito repellent DEET rather than Picaridin and to use higher doses of DEET because lower doses do not work well with older mosquitoes, according to the study in Nature Scientific Reports .

'Tully monster' mystery is far from solved, group argues
Last year, headlines in The New York Times, The Atlantic, Scientific American and other outlets declared that a decades-old paleontological mystery had been solved. The 'Tully monster,' an ancient animal that had long defied classification, was in fact a vertebrate, two groups of scientists claimed. Specifically, it seemed to be a type of fish called a lamprey. The problem with this resolution? Ac

Friction in the vacuum?
(Phys.org)—When three physicists first discovered through their calculations that a decaying atom moving through the vacuum experiences a friction-like force, they were highly suspicious. The results seemed to go against the laws of physics: The vacuum, by definition, is completely empty space and does not exert friction on objects within it. Further, if true, the results would contradict the prin

Measures of spike train synchrony for data with multiple time-scales
Background: Measures of spike train synchrony are widely used in both experimental and computational neuroscience. Time-scale independent and parameter-free measures, such as the ISI-distance, the SPIKE-distance and SPIKE-synchronization, are preferable to time-scale parametric measures, since by adapting to the local firing rate they take into account all the time-scales of a given dataset. New M

Time Fractional Cable Equation And Applications in Neurophysiology
We propose an extension of the cable equation by introducing a Caputo time fractional derivative.

Novel socio-ecological approach helps identifying suitable wolf habitats in human-dominated landscapes
About one third of the Swiss landscape offers suitable wolf habitat. Nonetheless, there is only a small fraction thereof where the wolf is tolerated by local communities. Those regions – characterized by both favorable environmental conditions and a positive attitude towards the wolf – are identified as candidate regions for the successful short to medium-term wolf expansion, according to a study.
