Experimenting with one cellular organism, slime mold, physarum polycefalum

Similarity to human brain

to grow slime mold on different glasses in order to achieve 3d model

Maybe is better to start with simulation in order make needed paterns

Next stage would be with living organism: at the point when it is grown, to dry it

15/12/2017---experiment one: start with waking up the slime molds

To have better samples to build the art installation, try to wake up old slime molds samples by growing them in the medium.

four samples:

A-normal medium(pure agar, salt, yeast, water..)+8-10 pieces of cereals

B-normal medium

C&D-normal medium+wet and old filter paper

samples are kept in dark lockers under 20 degrees

20/12/2017---experiment two: waking up new slime molds samples from Sinan

samples from the last experiment failed.

Sample A was seriously contaminated. Nothing happened in sample B, C, &D

reason could be too much cereals or others

repeat the experiment with 3 more samples:

all in same condition: medium(Compound agar, water...)+1 piece of cereal

samples are kept in dark lockers under 24-26 degrees

21/12/2017---Update on experiment two: bacteria

the samples look like contaminated by some bacteria in the middle

23/12/2017---Update on experiment two: failed

the samples are contaminated and slime molds didn't wake up

reasons could be the temperature was too warm for the slime molds, food was too little and it was not humid enough inside the mediums

02/01/2018---experiment three: grow new samples(from sinan) under suitable temperature

repeat the experiment with 4 more samples:

all in same condition: medium(Compound agar, water...)+3 pieces of cereal

A-sealed and kept on a shelf, 20 degrees;

B-not sealed and in a locker, 22 degrees;

C-sealed and kept in a locker, 22 degrees;

D-not sealed and kept on a shelf, 20 degrees.

08/01/2018---Update on experiment three: possibly slime molds once woke up and died

all the samples are contaminated to some extend, but sample B shows similar trace of growing slime molds according to the shape

I will try this sample again and another ones with new humid filter papers and wood chips(which i searched online are good mediums for slime molds)

got the sections of the human brain model, 10 layers in total
