abstract = {The central nucleus of the amygdala (CEA) is a brain region
that integrates external and internal sensory information
and executes innate and adaptive behaviors through distinct
output pathways. Despite its complex functions, the
diversity of molecularly defined neuronal types in the CEA
and their contributions to major axonal projection targets
have not been examined systematically. Here, we performed
single-cell RNA-sequencing (scRNA-seq) to classify
molecularly defined cell types in the CEA and identified
marker genes to map the location of these neuronal types
using expansion-assisted iterative fluorescence in situ
hybridization (EASI-FISH). We developed new methods to
integrate EASI-FISH with 5-plex retrograde axonal labeling
to determine the spatial, morphological, and connectivity
properties of ~30,000 molecularly defined CEA neurons. Our
study revealed spatiomolecular organization of the CEA, with
medial and lateral CEA associated with distinct molecularly
defined cell families. We also found a long-range axon
projection network from the CEA, where target regions
receive inputs from multiple molecularly defined cell types.
Axon collateralization was found primarily among projections
to hindbrain targets, which are distinct from forebrain
projections. This resource reports marker gene combinations
for molecularly defined cell types and axon-projection
types, which will be useful for selective interrogation of
these neuronal populations to study their contributions to
the diverse functions of the CEA.},
