Colour and form in the cortex

Descriptions of primate visual cortex suggest that object’s colour and orientation of its contours are analyzed by independent, anatomically segregated neural populations. Recent results, however, show that cortical neurons can simultaneously code for both attributes. Cortical neurons, as Daniel Kiper explains, are thus ideally suited to analyze real scenes, where luminance- and coloured-defined contours are highly correlated

Ca2+ phase waves emerge

Biology continues to astonish even in well-studied areas. The discovery of long-range Ca2+ phase waves presents one such example. Dirk van Helden and Mohammad Imtiaz explain
