Holistic processing unites face parts across time

When complementary halves of different familiar faces are combined into a new face, there is interference in the identification of either half. This "composite face effect" has been taken as strong evidence that faces are processed holistically. Here, we demonstrate that this effect can persist when the two parts of a face are separated by up to 80 ms of visual noise, showing that the parts of ...

Attention Unites Form and Function in Spatial Language

Traditionally, the processing of spatial terms has been explained independently of more general cognitive processes, operating upon strictly geometric representations of the objects being spatially related. Challenges to this idea have focused on either process or representation. Research on process has linked spatial language with attention, but has assumed only abstract representations of the...

The hearing gene Prestin unites echolocating bats and whales

Echolocation is a sensory mechanism for locating, ranging and identifying objects which involves the emission of calls into the environment and listening to the echoes returning from objects [1]. Only microbats and toothed whales have acquired sophisticated echolocation, indispensable for their orientation and foraging [1]. Although the bat and whale biosonars originated independently and diffe...

Common mechanism unites membrane poration by amyloid and antimicrobial peptides.

Poration of bacterial membranes by antimicrobial peptides such as magainin 2 is a significant activity performed by innate immune systems. Pore formation by soluble forms of amyloid proteins such as islet amyloid polypeptide (IAPP) is implicated in cell death in amyloidoses. Similarities in structure and poration activity of these two systems suggest a commonality of mechanism. Here, we investi...
