-★ If you have your own data with at least two signals that you suspect may be related, identify an appropriate functional connectivity analysis and apply it to the data.
+★ If you have your own data with at least two signals that you suspect may be related, identify an appropriate functional connectivity analysis and apply it to the data. Comment on why the chosen method was used.
+★ The "theta" rhythm, which is about 8 Hz in moving rodents, is important in coordinating the spike timing of hippocampal neurons. However, theta frequencies also appear in LFPs recorded from other brain areas, including the prefrontal cortex and the ventral striatum. One hypothesis is that those areas simply "inherit" theta activity from their hippocampal inputs. Test this idea using data from R020, which has electrodes in hippocampus and ventral striatum, and your chosen connectivity analysis method.
