The media regularly reports on findings based on neuroimaging studies, but rarely do they explain exactly what these techniques are, their benefits or what it’s like to actually participate in these types of studies. Today I’ll describe what a participant goes through when they volunteer for a cognitive neuroscience experiment using a neuroimaging technique called electroencephalography (EEG). Unfortunately, it is exceedingly common for participants to not understand how these techniques benefit previous behavioral findings. Simply stated, if I were a participant, I’d like to know why I needed to wear a weird swim cap and how it benefits the research being done.
EEG is a tool regularly used to view and record the changes in brain activity involved in the various types of cognitive functions while performing a task. [Read more…] about The value of neuroimaging techniques (and what those squiggly lines mean)
