MATERIAL DE LAS CLASES DEL CURSO:
Introducción
During the last years several new tools have been developed that made possible to dissect specific circuit players of precise animal behaviours. This lecture course is designed to provide PhD students and postdocs in neuroscience with a conceptual understanding of the techniques to study the connectivity and function of specific neuronal subtypes. The course will be divided into three main topics:
- The use of viruses to target specific neuronal subtypes: an up-to-date explanation of trans-synaptic viruses that allow for the identification of presynaptic circuits, retrograde viruses that target neuronal subpopulations according to their projection pattern, and intersectional approaches that combine Cre and Flip recombination through transgenic lines and/or virus delivery to dissect neuronal subclasses. Many of these strategies can be use not only to map the connectivity but also to manipulate the activity of neuronal subpopulations.
- Selective manipulation of neuronal activity in vivo: expression of light-sensitive channels or engineered receptors to depolarize or inhibit neurons through the delivery of light (optogenetics) or drugs (pharmacogenetics).
- Strategies to record neuronal activity in vivo: calcium imaging in superficial or deep structures using miniaturized microscopes, voltage-sensitive dyes to record neuronal firing activity, and single unit extracellular recordings of specific neuronal subpopulations identified by their response to light.
The course will be organized in lectures to present the theoretical aspects of each topic, followed by paper reading and discussion to illustrate the use of those methods and round tables to promote the implementation of these tools to the student’s own research.
