Elucidating the neural circuits supporting odor identification remains an open challenge.
Here, we analyze the contribution of the two output cell types of the mouse olfactory bulb …

Olfactory perception and behaviors critically depend on the ability to identify an odor across
a wide range of concentrations. Here, we use calcium imaging to determine how odor …

The olfactory cortex encompasses several anatomically distinct regions each hypothesized
to provide differential representation and processing of specific odors. Studies exploring …

Odor representations are initially formed in the olfactory bulb, which contains a topographic
glomerular map of odor molecular features. The bulb transmits sensory information directly …

In awake rodents, the neural representation of olfactory information in the olfactory bulb is
largely dependent on brain state and behavioral context. Learning-modified neural plasticity …

Highlights•Odor information is encoded in the distributed activity of piriform cortex
neurons.•Piriform uses complementary coding strategies to represent odor identity and …

Highlights•The glomerular organization in the mammalian olfactory bulb is differentially
transformed in higher-order olfactory areas.•The microcircuitry of the piriform cortex enables …

In the olfactory bulb, lateral inhibition mediated by granule cells has been suggested to
modulate the timing of mitral cell firing, thereby shaping the representation of input odorants …

The olfactory bulb (OB) is the first site of synaptic odor information processing, yet a wealth
of contextual and learned information has been described in its activity. To investigate the …

The ability to represent both stimulus identity and intensity is fundamental for perception.
Using large-scale population recordings in awake mice, we find distinct coding strategies …
