Structure and flexibility in cortical representations of odour space

Both piriform cortex and its sensory inputs from the olfactory bulb represent chemical odour relationships, but cortex reshapes relational information inherited from the sensory periphery to enhance odour generalization and to reflect experience.

Circuits drive cell diversity

Neurons of the same type can show functional differences. It turns out that this diversity is in part the result of the cells' adaptation to their specific neural networks. See Letter p.375

A biophysical signature of network affiliation and sensory processing in mitral cells

Functional heterogeneity within a class of neurons is investigated by comparing the intrinsic properties of pairs of mitral cells belonging to either the same or different glomerular circuits; this shows that neuronal excitability is stereotypic for mitral cells from the same olfactory network, indicating that local circuits are functionally adapted to process subtly distinct information.

Neuronal filtering of multiplexed odour representations

Optogenetic stimulation in the zebrafish olfactory bulb and downstream read out of activity in the homologue of olfactory cortex demonstrate how temporal filtering can extract specific components of neuronal codes.
