Fruit flies could one day provide new avenues to discover additional genes that contribute to a person's ability to learn and remember. Scientists at the University of Missouri are studying genes of fruit flies to explore why an individual fly can be a better learner than another. Many of those genes in fruit flies are similar to those found in people.

Past experiments studying how fruit flies' ability to learn and remember have involved "turning off" a single gene and watching the response. In this study, the scientists took a different approach by placing fruit flies in a box equipped with heating elements. [...] A fly's ability to avoid the heat measured how well it learned, and a fly's ability to avoid the hotter side of the box, even when the heat was off, measured its capacity to remember.

Patricka Williams-Simon [said] "We repeated the experiment with over 40,000 individual fruit flies from over 700 different genes to establish variation in performance. Then, we focused on the high and the low learning and memory performers." The scientists then took these results and applied genetic sequencing technology to determine if specific genes were responsible for these observed changes in a fly's behavior. They found nine genes that show a change between high and low performing files when it comes to learning and memory.

"All of these genes are previously known to affect the nervous system or the brain in some way, but none of them had previously been implicated in learning and memory," said Elizabeth King, an assistant professor of biological sciences in the MU College of Arts and Science. "Therefore, they represent novel areas to further investigate these behavioral traits."

While the study is considered basic research, Williams-Simon said their findings are important. "The better we can understand these traits in fruit flies, the more we can develop targeted studies in humans," Williams-Simon said.

    Did you even look at what those genes do, or just post random gene names?

    it is a universal adapter protein as it is used by almost all TLRs (except TLR 3) to activate the transcription factor NF-κB.

    https://en.wikipedia.org/wiki/MYD88 [wikipedia.org]

    NF-κB has also been implicated in processes of synaptic plasticity and memory.[6][7][8][9][10][11]

    https://en.wikipedia.org/wiki/NF-%CE%BAB [wikipedia.org]

    Then I bothered to search "MYD88 brain" and this was the top result:

    MyD88 signaling in brain endothelial cells is essential for the neuronal activity and glucocorticoid release during systemic inflammation

    In mice. That quote from wikipedia very specifically says "in that species, [the part you excerpted]"

    But either way, I'm probably wrong about it and I'll say you're right, but fight to the death for fucking keratin not affecting neural behavior(unless you count keeping your head warm).
