Cerebral cortical functional hyperconnectivity in a mouse model of spinocerebellar ataxia type 8 (SCA8)

Angela K. Nietz, Laurentiu S. Popa, Russell E. Carter, Morgan L Gerhart, Keerthi Manikonda, Laura P.W. Ranum, Timothy J. Ebner

This study uses Ca2+ imaging in a SCA8 mouse model to show hyperconnectivity in neocortical networks, with significant changes in sensory and association cortices predicting disease state.

To be and not to be: Wide-field Ca2+ imaging reveals neocortical functional segmentation combines stability and flexibility

Angela K. Nietz, Martha L. Streng, Laurentiu S. Popa, Russell E. Carter, Evelyn B. Flaherty, Justin D. Aronson, Timothy J. Ebner

This study uses wide-field Ca2+ imaging and spatial ICA to show that neocortical functional segmentation is stable across behaviors but flexible at shorter timescales.

Wide-field Calcium Imaging Reveals Widespread Changes in Cortical Connectivity Following Repetitive, Mild Traumatic Brain Injury in the Mouse

Samuel W. Cramer, Samuel P. Haley, Laurentiu S. Popa, Russell E. Carter, Earl Parker Scott, Evelyn B. Flaherty, Judith Dominguez, Justin D. Aronson, Lukas Sabal, Daniel A. Surinach, Clark C. Chen, Suhasa B. Kodandaramaiah, Timothy J. Ebner

This study uses calcium imaging to show that repetitive mild traumatic brain injury in mice causes long-term changes in cortical functional connectivity without affecting cognitive or motor function.
