Left: percentages of activated neurons after applying hypertonic solution (for Tmem63b Cre/+ : n = 37 neurons from 16 mice, for Tmem63b Cre/Cre : n = 25 neurons from 9 mice). Right: firing rates of activated SFO TMEM63B neurons from Tmem63b Cre/+ mice ( n = 29 neurons, left) and Tmem63b Cre/Cre mice ( n = 6 neurons, right) shown in left, before (Iso) and after hypertonic stimulation (Hyp).
