The eyes have it

Molecular genetic experiments are revealing how the fly brain generates behavioral responses to visual stimuli.

Why aye-ayes see blue.

The capacity for cone-mediated color vision varies among nocturnal primates. Some species are colorblind, having lost the functionality of their short-wavelength-sensitive-1 (SWS1) opsin pigment gene. In other species, such as the aye-aye (Daubentonia madagascariensis), the SWS1 gene remains intact. Recent studies focused on aye-ayes indicate that this gene has been maintained by natural select...

What Users Do: The Eyes Have It

Search engine result pages – the ten blue links – are a staple of document retrieval services. The usual presumption is that users read these one-by-one from the top, making judgments about the usefulness of documents based on the snippets presented, accessing the underlying document when a snippet seems attractive, and then moving on to the next snippet. In this paper we re-examine this assump...

The eyes have it!: an fMRI investigation.

For the past several years it has been thought that cues, such as eye direction, can trigger reflexive shifts in attention because of their biological relevance and their specialized neural architecture. However, very recently, reported that other stimuli, such as arrows, trigger reflexive shifts in attention in a manner that is behaviourally identical to those triggered by eyes. Nevertheless t...
