	60/120/hfn	non-IT	STS	unstable	no data	slope
n_out_lfp	108	30	12	25	94	62

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 [0.77 1.30], LFP [0.77 1.30])

pres = number of repetitions of each image
change stim = average response during last repetition / average response during first repetition, stimulus interval

CV = coefficient of variation of the interspike interval distribution

Selectivity

MUA

MUA	267	75.00	0	0.00

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 = 238 (66.85 %)
