3.13.21

The Halladay Lab has a new paper out, in Behavioural Brain Research, detailing the life long social behavioral deficits induced by early life stress and the finding that low dose ethanol counteracts some social deficts, specifically in adolescent females.

3.11.21

In collaboration with colleagues at the NIAAA and University of Miami, Lindsay Halladay published a review article in the Journal of Neurochemistry, Advances in understanding meso‐cortico‐limbic‐striatal systems mediating risky reward seeking.

12.15.20

In collaboration with researchers at the NIAAA, the Halladay lab published exciting new work in eLife, identifying a prefrontal-bed nucleus of the stria terminalis circuit in the regulation of fear under during uncertain threat. This work has clinical implications for understanding neural underpinnings of trauma-related disorders.

6.9.20

The Halladay Lab published a new study in the Journal of Neuroscience Research, highlighting the bed nucleus of the stria terminalis as a potential mediator of social behavior dysregulation following early life trauma.

and Memory, identifying two functionally

distinct neural populations in the extended

amygdala that encode and predict cued fear

learning.

1.28.20

Lindsay Halladay presented new Halladay Lab findings at the Winter Conference on Brain Research in Big Sky, MT. Two invited talks included data on the neural circuits governing defensive action selection, as well as fear responding in the face of uncertain outcomes - data shedding light on inappropriate defensive responding characteristic of anxiety disorders and PTSD.

1.16.20

In an interview with Elemental, Lindsay Halladayspoke about her recently published findings on the neural circuits regulating drinking behavior in "The Latest Findings on Why It’s So Hard to Quit Drinking."

12.18.19

Lindsay Halladay and colleagues at the

NIAAA published an article in Biological

Psychiatry, identifying a corticostriatal

circuit involved in regulating punished

ethanol seeking. Read the press release
