BrainsCAN's Postdoctoral Associates
Through the Postdoctoral Fellowship Program, BrainsCAN is bringing the world's most promising early career cognitive neuroscientists to Western University. Training the next generation of researchers is a key aim of BrainsCAN, and postdoctoral fellows are the engines of innovative research.
In fall 2017, the first set of fellows joined the program under the designation of a BrainsCAN Fellow or Postdoctoral Associate.

Investigating sex and dose-dependent cognitive impairments produced by adolescent THC exposure
Supervisor(s): Dr. Steven Laviolette, Dr. Susanne Schmid, Dr. Walter RushlowResearch Information:
Cannabis use during adolescence can lead to long-term cognitive deficits and is associated with an increased risk for neuropsychiatric disorders later in life. The primary psychoactive component of cannabis, tetrahydrocannabinol (THC), may interrupt normal brain maturation during this critical period of development, leading to long-term cognitive consequences. The specific neurobiological mechanisms of these impairments remain unknown. Using a preclinical model of adolescent THC exposure, this project will investigate the neural pathways and molecular changes underlying cognitive impairments produced by adolescent THC exposure. A variety of THC doses will be investigated because THC is known to produce biphasic effects on multiple cognitive processes, where low and high doses often produce opposite effects. Higher potency cannabis is also associated with greater cognitive risks. Moreover, THC is known to produce sex-specific effects, yet the majority of research on the effect of adolescent THC exposure has been done exclusively in males. This project will also address this knowledge gap and investigate the sex-dependent effects of THC on cognitive development. Results from this study will advance our knowledge of the long-term consequences of adolescent cannabis use and have the potential to influence the development of treatments for disorders with cognitive impairments.

Optogenetic manipulation of intracellular calcium ion dynamics to regulate neural plasticity during stress
Supervisor(s): Dr. Wataru Inoue, Dr. Julio Martinez-Trujillo, Dr. Marco Prado
Research Information:
Stress impairs cognitive ability in otherwise healthy individuals and dramatically affects memory and learning in disparate brain disorders such as depression, anxiety disorders and autism. The effects of stress on cognition is due in part to the dysregulation of neural plasticity. This project will explain the spatiotemporal association of internal calcium ion — one of the second messengers — to neural plasticity and their roles in stress-induced cognitive impairment in mouse models.

Neural and Computational Basis of Goal-Dependent Feedback Control
Supervisor(s): Dr. Andrew Pruszynski, Dr. Jörn Diedrichsen
Research Information:
Think fast — a colleague unexpectedly bumps into your arm while you're carrying your coffee mug. If the cup is full of hot coffee your reaction will look strikingly different than if the cup is empty. Understanding how the brain incorporates high-level contextual information while dealing with unexpected sensory feedback is essential in understanding movement. Yet, the brain regions and computational principles involved remain unclear. In this project we will generate a novel set of behavioural tasks, recording techniques, network models, and biomechanical modeling tools to elucidate the circuits and computations involved in using context and expectation to make feedback corrections in humans and NHP.
