Sex differences in the effects of 10 Hz and 40 Hz transcranial alternating current stimulation on spatial cognition in mice.
Article in Biology of sex differences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSex differences are crucial to understanding neuropsychiatric disorders, yet they are often overlooked in the development of therapies. Transcranial alternating current stimulation (tACS) shows promise for cognitive enhancement, but its sex-specific effects are largely unknown.
methodsIn this study, the effects of 10 Hz and 40 Hz tACS on spatial cognition were examined in male and female mice using three tests: the Y-maze to evaluate spatial recognition memory, the Barnes maze to evaluate spatial learning and memory related to punishment, and the reversal Barnes maze to evaluate reversal learning. General behaviors, such as anxiety, exploration, and locomotion, were evaluated using the elevated plus maze and open field tests.
resultsThe results showed that 40 Hz tACS improved spatial recognition memory in males, while 10 Hz and 40 Hz tACS enhanced spatial learning in females. Males learned faster, while females performed better initially in the spatial learning process. In addition, no significant effects of tACS were observed in reversal learning, spatial memory, anxiety, or exploration. Interestingly, males exhibited reduced locomotion compared to females across tasks, and tACS potentially exacerbated this difference.
conclusionsThis animal study suggests that tACS may influence spatial cognition differently in males and females. Our findings highlight the importance of considering the interaction between sex and stimulation frequency when optimizing tACS intervention parameters.
