• "Unlike laboratory stimuli such as sinusoidal grating or the Gabor patch, natural images generally contain signals broadly distributed over different spatial frequencies."
• "Then we examine the system response to sinusoidal input signals with varying frequencies to determine if the cell can distinguish between different regimes of information flow from the environment."
