Inferior temporal (IT) object representations have been intensively studied in monkeys and humans, but representations of the same particular objects have never been compared between the species. Moreover, IT's role in categorization is not well understood. Here, we presented monkeys and humans with the same images of real-world objects and measured the IT(More)
Perceptual decision making typically entails the processing of sensory signals, the formation of a decision, and the planning and execution of a motor response. Although recent studies in monkeys and humans have revealed possible neural mechanisms for perceptual decision making, much less is known about how the decision is subsequently transformed into a(More)
Voxel-Based Morphometry (VBM) has been used for several years to study differences in brain structure between populations. Recently, a longitudinal version of VBM has been used to show changes in gray matter associated with relatively short periods of training. In the present study we use fMRI and three different standard implementations of longitudinal(More)
Small differences between the left and right sides of otherwise symmetric traits are related to developmental instability and can indicate how well the genome is suited to current developmental conditions. As these small asymmetries (termed uctuating asymmetry, or FA) can reveal how well the genome is suited to the environment, researchers have postulated(More)
There has been substantial interest in whether birds use small degrees of asymmetry (fluctuating asymmetry , FA) in visual communication. However, there is a scarcity of experimental evidence for the visual role of FA. Hence, there is still much debate as to whether FA could be a visual cue. We address this issue by exploring whether European starlings,(More)
