Properties of LFPs
Power spectrum
Principal components
Selectivity of LFPs
Detailed example
200 ms presentation example
Correlation with basic image properties
Comparison of selectivity with different presentation times
Selectivity vs time
LFP responses extend beyond MUA responses
Lower frequencies in the LFPs show a more sustained response
Object preference biases across the population
Population preferences for objects and groups of objects
Summary of within group selectivity
Selectivity of spikes and LFPs
Sparsenss of MUA and LFP responses
No correlation between sparseness of MUA and LFP at each site
Criteria for object selectivity
Spikes versus LFPs
Spikes versus LFP in different analysis windows
Spikes versus LFP for 200 ms presentation case
LFP responses outside visual cortex
No visual selectivity in the LFPs outside visual cortex
Time course
Time course of MUA and LFP responses
