Summary

Story summary

A study in Nature Neuroscience finds that lowering Homer1 levels in the prefrontal cortex improves attention in mice by increasing GABA receptors and reducing neural noise.
The research indicates Homer1 influences attention during early brain development, with Homer1a and Ania3 variants significantly affecting focus.
Mice with reduced Homer1 performed better on attention tasks, linking gene regulation to cognitive performance.
