Researchers have explored the brain neuronal mechanism that allows the perception of familiar images even if they are indistinct. They found that the number of neurons responding to low-contrast rather than high-contrast visual stimuli increased in rats performing a visual orientation discrimination task after repeated experiences. These neurons showed stronger activities in correct-choice than incorrect-choice trials. These neurons efficiently represented low-contrast stimulations. Thus, the low-contrast preference in V1 activity may contribute to improved low-contrast visual. discrimination.
