Colouring the cortex
Article Abstract:
The activity of colour opponent neurons enable humans to see colour, and although such neurons are abundant in the first part of the visual pathway, they are not frequently observed in the second stage, the primary visual cortex (V1). Functional magnetic resonance imaging (fMRI) studies have previously indicated activity changes in regions of the brain when a certain stimulus is used. However Engel at colleagues have discovered differential responses to colour and contrast changes, showing that fMRI signal activity can respond to the entire range of colours.

Neurons in the orbitofrontal cortex encode economic value
Article Abstract:
Neurons in the orbitofrontal cortex (OFC) during the economic choice were shown to encode the value of offered and chosen goods. It was suggested that economic choice was essentially a choice between goods rather than actions and in this study, neurons in the OFC seem to be a good candidate network for value assignment underlying economic choice.
