This article indicated that understanding of new rules achieve suddenly instead of gradual learning. They use set shifting tast for rat, mimic Wisconsin card sorting test for human, and record extracellular signals. Then sorting the data to each neuron activity and analyze the properties of the population activities. They showed the properties changed transiently when the rat adjusted to a new rule. This may explains the mechanism of 'a-ha' experiments (moments of sudden insight.)

In this article, the Authors generated two photon microscopy using 2 pairs of AODs (audio-optical deflectors). The sampling ratio is over 20k Hz and recording area is 700(x) x 700(y) x 1400(z) um. It makes us to record the neural population activities with more large number of cells and high time resolution. Combing with other techniques, we may achieve recording single or a few columns level activity.

This is my first blog written in English. It is hard for me because I am not good at English well (and all other language including Japanese). I want to improve my English writing skills, so please let me know if you find some mistakes.
