Automated tracking and analysis of behavior in restrained insects.

Journal of neuroscience methods Nov 4, 2014
BACKGROUND: Insect behavior is often monitored by human observers and measured in the form of binary responses. This procedure is time costly and does not allow a fine graded measurement of behavioral performance in individual animals. To overcome th...
