FOS and Anxiety: In addition, we tested cFos expression in vHPC neurons 30 min and 24 h after SRS and found that the number of cFos‐positive neurons in the vHPC exhibited a tendency to increase 30 min after SRS (Figure S11A,B, Supporting Information), whereas no change in neuronal activity was observed 24 h after SRS (Figure S11C,D, Supporting Information), suggesting that increased neuronal activity in the vHPC may underlie the enhanced anxiety‐like behaviors after SRS, which awaits further studies.
