Estimating neuronal firing density: A quantitative analysis of firing rate map algorithms
Fig 10
Error and computation time across methods.
All plots are based on the 16-minute session data. Horizontal lines denote a significant (p < .05) post-hoc comparison, for simplicity only the balanced solution groups are compared. A) The mean integrated squared error (MISE) associated with each mapping method when using the balanced or minimum error parameters. Markers denote simulated place cells and the same 256 cells were tested using each method. B) The same as a but for computation time. Some methods have a bimodal distribution, the longer computation times represent the first time a map was generated for a recording session (8 unique sessions were simulated) and a dwell time map was created. Only these 8 values are shown for the tKSDE computation times. C) The accuracy with which place fields were detected for each mapping method. D) The proportion of empty bins remaining for each mapping method. E) The spike probability map and simulated spikes for an example simulated place cell. Below this, firing rate maps for this place cell generated using each method (columns) and the balanced solution parameters (top row) or minimum error solution parameters (bottom row). Text gives the bin size and smoothing parameters used.
