ニューロンの 雨中も続く 水迷路
An experimental procedure in behavioral neuroscience known as the Morris water maze is a method to assess the animals' ability of spatial learning and memory. In the experiment, test animals are placed in a pool filled with a pool of clouded water where they are supposed to swim, and scientists record the process how the animals find an invisible platform under the water. In this picture, two scientists are recording behavior of mice in an experiment using the Morris water maze. It rains reminding us of dendrites of neurons. One woman puts up an umbrella over the other to prevent the recorder from being wet.
This wooden stand called “Marudai” is used for braiding a Kumihimo, a decorative belt used for tying on a kimono sash. This particular Marudai has the top surface engraved with a part of the codon table in order to translate nucleotide sequences of genes into the pattern of Kumihimo (polypeptide chain). The Marudai and bobbins actually play the role of ribosomes and tRNAs that synthesize proteins by translating mRNA sequences into amino acid sequences. The color of threads had changed depending on amino acids. The pattern of Kumihimo being braided in this drawing was obtained from the sequence of human insulin. Nothing can be as cool as gene sequences, which design the pattern of brilliantly colored Kumihimo.
