Task: Answer Verification
Input (English): Question: Is altered synaptic transmission in the hippocampus of the castrated male mouse reversed by testosterone replacement?
Answer: Suppression of PPF and impairment of the potentiation by PBS in CA1 hippocampal neurons was observed in castrated male mice and these changes were reversed by testosterone injection. These findings suggest that altered synaptic transmission in the castrated male mouse is caused by disturbance of inhibitory neuronal networks that are influenced by testosterone.
Output (English): yes
