NSCI 527 - Brain Networks & Cognition
This course will focus on the phenomenon of oscillatory processes in the brain networks and how our growing understanding of this phenomenon contributes to our current thinking and interpretations of brain mechanisms underlying cognitive functions. How do those processes come about and what role do they play? Are they an epiphenomenon or an epitome of complex brain processes? A bulk of the existing experimental data will be presented demonstrating the abundance of brain oscillations at different levels of brain organization. A conceptual framework will be considered which provides a theoretical support for an important role of oscillations in the formation of neural networks and integrative processes in the brain. We will consider how oscillatory processes are studied and how brain networks involved in various cognitive tasks can be delineated. Various methods of analysis of brain activity will be reviewed which include extracellular recordings in vitro and in vivo as well as noninvasive and intracerebral recordings from human subjects based on EEG/ERP, MEG and fMRI/PET and ECoG. Can oscillations be used to directly communicate with the brain (brain-computer interface)? How are brain oscillatory processes disturbed in various neurological disorders and can this be a contributing factor in the pathogenesis of diseases like autism and epilepsy? Can brain oscillations be intentionally modified by various methods of brain stimulation such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) and how may such modulation affect cognitive functions? Can patients benefit from such modulation? The course will provide a comprehensive review of brain oscillatory processes and networks and their role in cognitive functioning.
    Classes will include an introductory lecture followed by discussion of several research articles (discussion lead by individual students). In addition, several classes will be turned into a lab. This will give  students some hands-on experience measuring brain activity. As a capstone project, students will propose simple experiments, collect and analyze the data, and write up the final report testing a specific hypothesis investigating brain oscillatory processes/networks in relation to cognitive functioning.
