Colour tuning in human visual cortex measured with functional magnetic resonance imaging
Article Abstract:
Three types of neural pathways representing colour have been identified using perceptual experiements. Attempts to find neurons in the primary visual cortex with response properties resembling these pathways have been inconsistent. Responses in the human brain to several colours were examined using functional magnetic resonance imaging. The responses suggest that colour signals relevant to perception are encoded in visual cortical areas V1 and V2.

Scaling and the design of miniaturized chemical-analysis systems
Article Abstract:
Micrometre-scale total analysis systems have of late, revived interest in the scaling laws, which compare the relative performance of a system as the dimensions of the system change and can predict the operations success of miniaturized chemical separation, reaction and detective devices before they are fabricated. Some of the important principles that contribute to the design of novel mu-TAS are reviewed.

Coordinated proton tunnelling in a cyclic network of four hydrogen bonds in the solid state
Article Abstract:
Proton tunnelling may occur in a coordinated way involving several hydrogen bonds simultaneously, which may affect the linear and circular networks of hydrogen bonds. NMR relaxometry was used to observe coordinated proton tunnelling in a cyclic array of hydrogen bonds in solid p-tert-butyl calix(4)arene at low temperature. The experiment is in good agreement with theoretical predictions.
