The Role Of The Basolateral Amygdala In Gaze Avoidance Behaviour, Brainscan , Western University, Julio Martinez-Trujillo, Lena Palaniyappan, Robert Nicolson
The Role Of The Basolateral Amygdala In Gaze Avoidance Behaviour, Brainscan , Western University, Julio Martinez-Trujillo, Lena Palaniyappan, Robert Nicolson
Project Summaries
We are researching the neural circuits involved in human social interactions and how they are affected during mental disease, in particular the circuits involved in the pattern of eye movements (known as gaze behaviour) in social settings.
The Impact Of Violent Gaming On The Brain As A Function Of Individual Differences In Trait Empathy, Brainscan , Western University, Derek Mitchell, Elizabeth Finger, Richard Neufeld
The Impact Of Violent Gaming On The Brain As A Function Of Individual Differences In Trait Empathy, Brainscan , Western University, Derek Mitchell, Elizabeth Finger, Richard Neufeld
Project Summaries
In this project, we will uncover any existing interaction between violent media and the capacity for empathic reactions (known as trait empathy) at a neural level, as the foundational milestone for the kind of large-scale study discussed above.
The level of trait empathy varies by individual - we will explore whether exposure to violent media exacerbates the difficulties that those with low trait empathy already show in relating to the emotions of others
Role Of Microglia Signaling In Brain Circuit Development And Cognition, Brainscan, Western University, Vania Prado, Marco Prado, Wataru Inoue
Role Of Microglia Signaling In Brain Circuit Development And Cognition, Brainscan, Western University, Vania Prado, Marco Prado, Wataru Inoue
Project Summaries
We have generated two mouse models in which we can control the Gq and Gisignalling in microglia during specific periods of brain development so we can explore the mechanisms behind abnormal microglial function.
Using our mouse models, we can stimulate these signalling pathways during the critical period of postnatal brain development to understand whether they impact adult cognition by influencing normal synaptic pruning. Mouse models of autism show issues with social memory, attention, sociability and hyperactivity. We will therefore assess those behaviors in our mouse models to determine if any autism-like behaviours are present.
Attention Bias Modification Training As A Potential Preventative Tool, Brainscan, Western University, Elizabeth Hayden, Marc Joanisse, Pan Liu, Koraly Perez-Edgar, Thomas Olino
Attention Bias Modification Training As A Potential Preventative Tool, Brainscan, Western University, Elizabeth Hayden, Marc Joanisse, Pan Liu, Koraly Perez-Edgar, Thomas Olino
Project Summaries
We will use eye-tracking techniques to understand more about attentional bias and how it changes through ABM training.
Through neuroimaging, we will look at 'resting state functional connectivity', which is the activity and communication in the brain when a person is not engaging in any activity themselves. There are resting-state patterns of brain activity that have been identified in the brains of youth with depression, anxiety and related disorders, but we do not know if these brain patterns can be used to identify those at risk for these disorders. We also don't know if preventative approaches to depression and anxiety, …
The Prefrontal Cortex And Obesity: A Health Neuroscience Perspective, Brainscan, Western University, Cassandra J. Lowe, Amy C. Reichelt, Peter A. Hall
The Prefrontal Cortex And Obesity: A Health Neuroscience Perspective, Brainscan, Western University, Cassandra J. Lowe, Amy C. Reichelt, Peter A. Hall
Research Summaries
The level of activity within an individual’s prefrontal cortex seems to be critical to dietary self-control and the likelihood of overconsumption and obesity. Lower activity can make individuals more vulnerable to the appeal of calorie-rich foods. Sustained overconsumption and obesity can cause changes in the prefrontal cortex that further discourage dietary self-regulation, creating a reciprocal relationship that reinforces the poor dietary choices and encourages overconsumption.
