[Coggroup] CRAM THIS MONDAY NOV 25th
by Cognitive Research at McGill 25 Nov '19

25 Nov '19

Hi All, The final CRAM session of the semester will be held on November 25th (Monday) from 12-1pm, in room 735 of 2001 McGill College Avenue. Coffee and light snacks will be provided. Please BYOM (bring your own mug). All are welcome! Dr. Cecilia Flores from the Departments of Psychiatry and of Neurology and Neurosurgery will be speaking to us about maturation of the adolescent prefrontal cortex. See below for abstract. Title: The adolescent prefrontal cortex is still under construction Abstract: Adolescence is an age of increased vulnerability to psychiatric condition that involve alterations in prefrontal cortex (PFC) circuitry and cognitive dysfunction. In my lab we are interested in understanding the cellular and molecular processes that are ongoing in the PFC during this developmental age and how these events are impacted by experience, including drugs of abuse and stressors. This talk focuses on the adolescent maturation of dopamine neurons and on the emerging role of the Netrin-1 guidance cue system and its microRNA regulators in the gradual adolescent unfolding of dopamine connectivity, including dopamine axon tagging and pathfinding. I discuss how drugs of abuse and chronic social stress alter these maturational events, inducing susceptibility or resilience later on in life and how these effects are modified by sex, dose, and specific age within adolescence. Warm regards, The CRAM Team (Kevin da Silva Castanheira, Anna Mini Jos, & Azara Lalla)

Dear all, We are happy to announce the next CRAM (Cognitive Research at McGill) session of this term on Friday, November 8th. Dr. Milica Miocevic will be speaking to us about Bayesian Mediation analysis. The talk will span from 12pm-1pm in room 1552 of 2001 McGill College Avenue. Coffee and light snacks will be provided. Please BYOM (bring your own mug). All are welcome! ---- Title: Bayesian Mediation analysis Dr. Milica Miocevic, McGill University ---- Abstract: Mediation analysis is used to study intermediate variables (M) that transmit the effect of an independent variable (X) on a dependent variable (Y). For example, an intervention designed to reduce unhealthy habits (X) might affect fruit and vegetable consumption (M), which in turn might affect general health (Y). In this hypothetical study, the quantity of interest is the indirect effect of the intervention on general health through fruit and vegetable consumption. Mediation analysis can be performed using both classical (frequentist) and Bayesian approaches (Yuan & MacKinnon, 2009). In recent years social science researchers have turned to Bayesian methods when they encounter convergence issues (Chen, Choi, Weiss, & Stapleton, 2014), issues due to small samples (Lee & Song, 2004), and when they wish to report the probability that a parameter lies within a certain interval (Rindskopf, 2012). Bayesian methods can easily accommodate the asymmetric distributions of the mediated effect and other functions of the mediated effect, e.g. effect size measures and causal estimates of indirect and direct effects. Furthermore, Bayesian methods provide an intuitive framework for the inclusion of relevant prior information into the statistical analysis. In this talk I will discuss the advantages of Bayesian mediation analysis, summarize recommendations that can be made for applied researchers based on the methodological literature on Bayesian mediation analysis thus far, and conclude with future directions for this line of research.

Dear all, We are happy to announce the next CRAM (Cognitive Research at McGill) session of this term on Friday, November 1st. Dr. Vishnu Murty will be speaking to us about how decision- making engages mesolimbic-hippocampal circuits to stabilize experiences into long-term memory. The talk will span from 12pm-1pm in room 1552 of 2001 McGill College Avenue. Coffee and light snacks will be provided. Please BYOM (bring your own mug). All are welcome! ---- Title: Decision-making engages mesolimbic-hippocampal circuits to stabilize experiences into long-term memory Dr. Vishnu Murty, Temple University ---- Abstract: While a growing body of literature has characterized how individuals use episodic memory to guide decision-making, relatively little is known as to how decision-making influences downstream memory. The ability for individuals to actively make decisions engages regions with the mesolimbic system, which are known to facilitate episodic- memory. In this talk, I will present a series of studies characterizing how decision-making enhances episodic memory for chosen items. Using behavioral and neuroimaging markers, I will provide evidence that engagement of mesolimbic systems during encoding results in the stabilization of memory for decision outcomes over time, consistent with models of systems-level consolidation. Together, these findings support a model by which actively deciding to encode information enhances memory consolidation to preserve episodic memory for outcomes, a process that may be facilitated by re-exposure to the original decision-making context.
