Hypothesis
Do rats with induced cortical microgyria exhibit deficits in spatial working memory?
Conclusion
Rats with induced microgyria showed persistent deficits in spatial working memory compared to sham-treated rats.
Supporting Evidence
- MG rats made significantly more errors than shams during initial testing.
- Memory deficits in MG rats were evident even after 60 days of testing.
- Both groups showed learning, but MG rats performed less effectively.
Takeaway
Rats with brain damage from microgyria have trouble remembering where to find things, even after a lot of practice.
Methodology
The study used a delayed match-to-sample radial water maze task to assess working memory performance in rats with microgyria and sham controls.
Limitations
The study only included male rats, which may limit the generalizability of the findings.
Participant Demographics
Adult male Sprague-Dawley rats.
