Title: Unilateral loss of tyrosine hydroxylase in adult midbrain dopaminergic neurons reveals reduction to neuregulin1 in rat model of acute dopaminergic dysfunction

Lacey K. Greer, Abigail E. Harr, Alexander F. Hoffman…·Brandon K. Harvey

This study creates a rat model of adult dopamine loss by knocking out tyrosine hydroxylase and identifies early transcriptional changes, including reduced neuregulin1, in dopaminergic neurons and surrounding cells.

Shifts in attentional demand are accompanied by sex-specific patterns of insula-frontal cortical interactions in mice

Abigail E. Harr, Matthew R. O’Leary, E Vogt…·Henry L. Hallock

This study examines sex-specific insula-frontal cortical interactions in mice during an attention task, finding differences in synchrony and theta-gamma coupling between males and females.
