The Dilemma of Multidimensionality

Note

Please read the paper The Art of Brainwaves, if you want to know more about how we come up with these plot types.

EEG – multidimensional data and could be presented differently.

Possible dimensions:

  • Voltage (must have)
  • Time
  • Number of channels (1-128)
  • Spatial layout of channels
  • Experimental conditions
  • Trials/subjects

Each way of ERP presentation is a choice of dimensions. Hard to show meaningfully more than 3 dimensions.

Plot types

Each plot type can represent several dimensions. Here we represented 8 plot types.
