Recording protocol. A, Location of stimulation electrode (black lines) in the corpus callosum and recording electrode pipette (red lines) in the dorsomedial striatum (blue area) of coronal brain slice. B, Input-output curve (mean pop spike size vs stimulation current) in male, diestrous, and estrous mice. Input current ranged from 0.1 to 1.5 mA. Error bars show +/– one standard error. N: sample size. C, Stimulation protocol for entire recording consisted of 15 min of baseline, theta-burst stimulation (TBS), and 30 min of follow-up. D, TBS protocol consisted of 10 trains of 10 bursts at 10.5 Hz, with each burst containing four pulses at 50 Hz. One train is illustrated.
