Extended Data Figure 2 : Effects on freezing by baseline optogenetic stimulation and freezing for all behavioural groups.

From: Amygdala interneuron subtypes control fear learning through disinhibition

Extended Data Figure 2

a, Effects of optogenetic manipulations of PV+ or SOM+ cell activity on baseline freezing levels. Illumination patterns resemble stimulations during the CS in the conditioning paradigms (10 s of 300-ms blue light pulses at 0.9 Hz or 10 s continuous yellow light). b, Freezing values during fear retrieval for all behavioural groups with optogenetic PV+ or SOM+ cell manipulations during the CS, US or CS+US. Freezing levels are compared between the internal control CS1 and CS2 which was paired with optogenetic stimulation during the conditioning.
