David A Leopold. Nature. .

Abstract

Analysis of a selected class of neuron in the brain of living animals using functional magnetic resonance imaging (fMRI) opens up a new horizon for mapping genetically specified neural circuits.

Lee et al. genetically modified rat cortical neurons to produces light-sensitive, membrane channels. They find that selective optical stimulation of cell bodies in the cortex (a) or axons in the thalamus (b) lead to fMRI responses in both regions. The strongest and most abrupt responses, however, were detected in the cortex after its direct stimulation.
