    in Foto 3 you see fins on either side of the worm.
    Could it be Enterobius vermicularis ?
    Though I don't think they are ever found in the brain.

    I agree with Kathy. It was an 'emerging zoonosis' as far back as 2002. See: http://wwwnc.cdc.gov/eid/article/8/4/01-0273_article.htm

    The alae and excretory columns of Baylisascaris procyonis can be seen in slide 3 of 6.

    Keep the racoons out of your yard!

    Toxocara spp. can also migrate to the brain.
