Figure 5. Mice raised under EE are resistant to stress-induced spine loss and texture discrimination defects.
a, Schematic of EE. b, EE prevented RS-induced decrease in PV+ IN activity. c, Both stressed and unstressed EE mice had elevated activation of NG+ neurons compared to unstressed, non-EE control mice. d, Stress increased SOM+ neuron activation in both control and EE mice; EE had no effect on SOM+ neuron activation. e,f, EE increased both spine formation (e) and elimination (f) compared to unstressed, non-EE control mice. Stress did not further alter spine dynamics in EE mice. g, Both stressed and unstressed EE mice exhibited normal texture discrimination.
