Title: "Making up your mind, the specification and integration of interneurons into the cortex"

Abstract: My talk will be focused on two complementary aspects of cortical interneuron development.  Firstly, from a developmental genetics vantage we are examining the trajectories by which cortical interneurons are generated from their anlage, the three ganglionic eminences, the medial, lateral and caudal ganglionic eminences.  Historically, this has involved fate mapping these progenitor zones (Wichterle et al., 2001; Nery et al., 2003, Butt et al., 2005, Miyoshi et al., 2007, 2010).  More recently this work has been complemented by single cell RNA-seq analysis (Mayer et al., in preparation) demonstrating the underlying logic by which interneuron and projection neurons are specified during development.  

Secondly, the laboratory has increasing intrigued by postnatal events by which cortical interneurons become integrated into brain circuits. Beginning with the recognition that modulation of activity can affect both the migration and morphological development of interneurons (De Marco et al., 2011), the laboratory has become interested in the connection between activity, gene expression (Demarco et al., 2015) and alternative splicing (Wamsley et al., 2018).   I will discuss recent evidence indicating that the splice factors Nova1 and Nova2 direct synaptogenesis in response to activity mediated splicing.

 

About Neuroscience Seminars

Neuroscience seminars at the QBI play a major role in the advancement of neuroscience in the Asia-Pacific region. The primary goal of these seminars is to promote excellence in neuroscience through the exchange of ideas, establishing new collaborations and augmenting partnerships already in place.

The scheduled QBI Neuroscience Seminar series are held on Wednesdays from 11am-12pm in the Level 7 Auditorium of the Queensland Brain Institute, Building 79, St Lucia Campus, The University of Queensland. Additional seminars may be held at other times as listed below.
