The lateral hypothalamic nucleus (LHy) is located in the dorsolateral hypothalamus of birds, and it is essential to many life processes. However, limited information is available about the role of LHy in mediating locomotive behaviors. In this work, we investigated the structure and function of LHy in pigeons (Columba livia) by Nissl staining, immunohistochemical (IHC) staining, insituhybridization (ISH) staining and constant current stimulation methods.

In this study, we applied spatial transcriptome sequencing and single-nucleus RNA sequencing (snRNA-seq) to explore the cellular organization and molecular characteristics of the avian OT from two species: and . We identified precise layer structures and provided comprehensive layer-specific signatures of avian OT.

PoA plays a vital role in emotion regulation and is considered a part of the amygdala in birds. However, the regulatory functions responsible for motor behaviors and emotions between PoAb and PoAc are poorly understood.
