＜abstract＞
The brain's unique mental abilities are thought to emerge from the processing of information by networks of neurons. To study this, isolated neurons were grown over glass dishes embedded with multiple electrodes (multi-electrode arrays, or MEA). Neurons use electricity as one method to communicate with each, and an MEA can be used to both record and stimulate nearby neurons, thus providing 2-way access for a researcher. Using these tools, we look for answers as to how can cognition arise from the activity of neurons in a network: learning, memory, creativity, etc. By providing the neurons with an artificial body (embodiment), we see if the neurons can learn anything about their new body and/or the environment with which they now interact. A special example will be presented: neurons and an MEA were combined with a robotic drawing machine developed in collaboration with two Australian artists. The system was termed MEART (MEA + aRT) and provided a foundation from which to address both scientific and artistic inquiries.
