In your brain there are different types of cells.
Firstly there are the neurons (the prima donnas that we believe do most of the communication of information). Next there are the microglia cells, which act as the first and main line of active immune defence in the brain. There are also oligodendrocyte, that wrap protective sheets around the branches of the neurons and help them to pass signals.
And then there are astrocytes.
These are the ‘helper cells’ which maintain a comfortable environment for the neurons and aid them in their task. Recently, researchers in California reported an curious observation in the Parkinsonian brain: some astrocytes have entered an altered ‘zombie’-like state. And this might not be such a good thing.
In today’s post, we’ll review the research and discuss what it could mean – if independently replicated – for the Parkinson’s community.

I don’t understand the current fascination with zombies.
There are books, movies, television shows, video games. All dealing with the popular idea of dead bodies wandering the Earth terrifying people. But why the fascination? Why does this idea have such appeal to a wide portion of the populous?
I just don’t get it.
Even more of a mystery, however, is where the modern idea of the ‘zombie’ actually came from originally.
You see, no one really knows.
Huh? What do you mean?
Some people believe that the word ‘zombie’ is derived from West African languages – ndzumbi means ‘corpse’ in the Mitsogo language of Gabon, and nzambi means the ‘spirit of a dead person’ in the Kongo language. But how did a word from the African continent become embedded in our psyche?
Others associate the idea of a zombie with Haitian slaves in the 1700s who believed that dying would let them return back to lan guinée (African Guinea) in a kind of afterlife. But apparently that freedom did not apply to situations of suicide. Rather, those who took their own life would be condemned to walk the Hispaniola plantations for eternity as an undead slave. Perhaps this was the starting point for the ‘zombie’.
More recently the word ‘zonbi’ (not a typo) appeared in the Louisiana Creole and the Haitian Creole and represented a person who is killed and was then brought to life without speech or free will.
Delightful stuff for the start of a post on Parkinson’s research, huh?
But we’re going somewhere with this.
Today’s (experimental) post provides something new – an overview of some of the major bits of Parkinson’s-related research that were made available in January 2018.
In January of 2018, the world was rocked by news that New Zealand had become the 11th country in the world to put a rocket into orbit (no really, I’m serious. Not kidding here – Click here to read more). Firmly cementing their place in the rankings of world superpowers. In addition, they became only the second country to have a prime minister get pregnant during their term in office (in this case just 3 months into her term in office – Click here to read more about this).
In major research news, NASA and NOAA announced that 2017 was the hottest year on record globally (without an El Niño), and among the top three hottest years overall (Click here for more on this), and scientists in China reported in the journal Cell that they had created the first monkey clones, named Zhong Zhong and Hua Hua (Click here for that news)
