Different subtypes of projection neurons in the mouse olfactory bulb are defined by distinct gene expression patterns and transcription factor networks.

Single-cell transcriptomes of Drosophila olfactory projection neurons correspond to previously defined cell types, exhibit unique characteristics at different developmental stages, and reveal cell-type-specific gene expression programs in development and function.

Dynamic local microenvironments in Drosophila facilitate axonal projection direction transitions in the absence of clear landmarks.

Advanced genetics and imaging reveal wiring logic underlying the olfactory map organization in the developing fruit fly brain, and strategies employed by projection neurons to target dendrites to specific locations in a timely manner.

Lmo4 specifies two neuron subclasses in the mouse neocortex by promoting postnatal co-expression of the transcription factors Ctip2 and Satb2 via chromatin remodelling in a time and area-specific manner.

Stk11 and Fos expression plays an important role in CTA long-term memory formation by modulating the intrinsic excitability of BLApn.

The organization of olfactory projection neurons and their synaptic connectivity with third-order neurons studied along with olfactory responses suggest that the labeled-line design is partially at work in the Drosophila olfactory system.

A multiplexed retrograde virus tracing method captures single-neuron projectome and transcriptome simultaneously.

Sister projection neurons in the mammalian olfactory system do not share sensory synaptic input indicating that lineage-independent mechanisms regulate their synaptic connectivity with the olfactory sensory neurons.

Neurons in the fruit fly olfactory system respond most strongly to the sudden appearance of an odor, and to odors that are changing rapidly in strength, but are relatively insensitive to the absolute levels of an odor.
