60/120/hfn = peaks at 60 Hz or harmonics or high-frequency noise
non-IT = sites outside IT or STS
STS = sites in STS
unstable = unstable recordings
no data = sites without enough number of repetitions
slope = number of sites with change in slope larger than threshold (MUA [0.25 4.00], LFP [0.25 4.00])

nsites selective = number of sites with p ANOVA < threhsold=0.001000
percentage selective = percentage of total sites analyzed that were selective
stimulus = stimulus interval [100;300) ms with respect to stimulus onset
background = background interval [-200;0) ms with respect to stimulus onset

number of selective images and variance ratio

number of sites with at least 1 selective image = 348 (66.67 %)
