Why study prairie voles?
Most of what we know about the social brain has been derived from the study of adult animals. However, social behaviors and brains are extremely dynamic and exhibit plasticity over the entire lifespan. There is still much to learn about how changes in neurobiology and cellular function enable animals to adaptively shift their social behaviors across life stages. To this end, the Hiura lab uses molecular genetic techniques and rigorous behavioral analysis to investigate how developing neural circuits and structures are shaped by interactions between biology and environmental experiences.
Social experiences play a crucial role in scaffolding brain development, but the ways in which changing neural circuits are shaped by early social interactions to facilitate adult bonding remains unknown. We use the socially monogamous prairie vole as a model system to probe features of the developing monogamous brain. This work has important translational potential for understanding how the atypical development of social circuits may contribute to maladaptive disease states.
To investigate complex social behaviors, we use a combination of manual behavioral annotations and AI pose-estimation modeling software like DeepLabCut. These techniques allow us to keenly observe how suites of social behaviors change over the course of vole development.
University of Colorado Boulder Land Acknowledgment
The University of Colorado Boulder, Colorado’s flagship university, honors and recognizes the many contributions of Indigenous peoples in our state. CU Boulder acknowledges that it is located on the traditional territories and ancestral homelands of the Cheyenne, Arapaho, Ute and many other Native American nations. Their forced removal from these territories has caused devastating and lasting impacts. While the University of Colorado Boulder can never undo or rectify the devastation wrought on Indigenous peoples, we commit to improving and enhancing engagement with Indigenous peoples and issues locally and globally.
We will do this by:
-
Recognizing and amplifying the voices of Indigenous CU Boulder students, staff and faculty and their work.
-
Educating, conducting research, supporting student success and integrating Indigenous knowledge.
-
Consulting, engaging and working collaboratively with tribal nations to enhance our ability to provide access and culturally sensitive support and to recruit, retain and graduate Native American students in a climate that is inclusive and respectful.
