Answer to Question 1

Answer: Pros high temporal resolution, low invasiveness, and low cost; Cons disrupted by slight movements, poor spatial resolution

Answer to Question 2

Answer: EEG and ERP have poor spatial resolution but excellent temporal resolution, low invasiveness, and are relatively low cost. MEC have good spatial resolution (for sulci only) and excellent temporal resolution; their invasiveness is low but cost is high. PET has good spatial resolution but poor temporal resolution. PET is highly invasive and costly. MRI and fMRI have excellent spatial resolution and marginal temporal resolution. Invasiveness is low but the cost is high. Optical imaging has poor spatial resolution and marginal temporal resolution. It is moderately invasive but the cost is low.
