About
I am a neuroscientist at the University of Prince Edward Island. My main research focus is hippocampal neurogenesis. Neurogenesis describes the process of birth, maturation and integration of neurons. It takes place in rodents and humans from development to old age. Neurons born during adulthood are more plastic and morphologically more complex than developmentally-born neurons. What can adult-born neurons do that developmentally-born dentate neurons are not able to do? What are their special features that make them unique? Are they connected differently in the network? And how is their production regulated? We know that certain environmental stimuli such as running can induce the formation of new neurons, whereas stress and ageing decrease their number. My goal is to clarify the impact of neurogenesis on behaviour and identify mechanisms how neurogenesis can be manuipulated to create new treatments for depression and other neurological disorders. For updates on my current research at UPEI check out my lab website https://projects.upei.ca/seiblab/
Research
Stem cells exist in all organs of the human body, but the brain was long thought to have none and thus, no regenerative potential. However, within the last 2 decades, it has become well accepted that stem cells exist in the human brain and that new neurons are born every day, even in old age. These neurons are mainly produced in the hippocampus, part of the limbic system associated with memories and emotions. The lack of new-born neurons has been associated with many neurological disorders.

TEACHING AND MENTORING
I was an instructor of PSYC 306 - Principles of Animal Behaviour and PSYC 460 - Behavioural Neuroendocrinology at the University of British Columbia. During my graduate and postdoctoral training I supervised and mentored a total of 20 undergraduate and graduate students. I gave multiple guest lectures in 2nd and 3rd year undergraduate courses and instructed several undergraduate and graduate Molecular Neurobiology lab courses.
