Ohzawa Lab Tour: Jan. 2010 (English) / 大澤研ラボツアー(英語) :研究室での実験の様子をビデオで紹介します。(右端のコラムに話した内容の全文テキストあります。)
Izumi Ohzawa gives a video tour of the lab. Responses are recorded from just one neuron in the visual cortex, and the neuron is stimulated by various synthetic visual patterns displayed on a computer monitor.
