| Description | : | Cat everything.
"And you do not want to get Toxoplasma into a fetal nervous system. It's a disaster... Two really interesting things. Back to dopamine and the tyrosine hydroxylase gene that Toxo somehow ripped off from mammals, which allows it to make more dopamine. Dopamine levels are too high in schizophrenia. That's the leading suggestion of what schizophrenia is about neurochemically. You take Toxo-infected rodents and their brains have elevated levels of dopamine. Final deal is, and this came from Webster's group, you take a rat who's been Toxo-infected and is now at the state where it would find cat urine to be attractive, and you give it drugs that block dopamine receptors, the drugs that are used to treat schizophrenics, and it stops being attracted to the cat urine. There is some schizophrenia connection here with this", www.edge.org/3rd_culture/sapolsky09/sapolsky09_index.html GOTO Complexity |
