Morphological variation suggests that chitinozoans may be fossils of individual microorganisms rather than metazoan eggs

Computational modeling suggests that response properties rather than spatial position determine connectivity between olfactory glomeruli.

Olfactory responses require the representation of high-dimensional olfactory stimuli within the constraints of two-dimensional neural networks. We used a computational model of the honeybee antennal lobe to test how inhibitory interactions in the antennal lobe should be organized to best reproduce the experimentally measured input-output function in this structure. Our simulations show that a f...

Reversed Priming Effects May Be Driven by Misperception Rather than Subliminal Processing

A new paradigm for investigating whether a cognitive process is independent of perception was recently suggested. In the paradigm, primes are shown at an intermediate signal strength that leads to trial-to-trial and inter-individual variability in prime perception. Here, I used this paradigm and an objective measure of perception to assess the influence of prime identification responses on Stro...

The dairy fat paradox: Whole dairy products may be healthier than we thought

New brain research suggests that emotions, not IQ, may be the true measure of human intelligence

Do students think that difficult or valuable materials should be restudied sooner rather than later?

Despite the clear long-term benefits of spaced practice, students and teachers often choose massed practice. Whether learners actually fail to appreciate the benefits of spacing is, however, open to question. Early studies (e.g., Zechmeister & Shaughnessy, 1980) found that participants' judgments of learning were higher after massed than after spaced repetitions, but more recent studies have fo...
