Topic: invariant visual features

In systems neuroscience, animals are often trained until they saturate the psychometric function, producing stereotypical behaviors. This may obscure important system properties, such as generalization and neural correlates. In this study, we trained and tested mice on visual texture classification problems, where they needed to generalize at test time based on mid-level visual features. After learning, mice consistently discriminated the training stimuli at a high accuracy, while their performance on test stimuli varied systematically across categories. To determine a possible neural basis f
