Abstract Adaptive behavior requires integrating prior knowledge of action outcomes and sensory evidence for making decisions while maintaining future actions. As outcome- sensory-based are often tested separately, it is unclear how these processes integrated in the brain. In a tone frequency discrimination task with two sound durations asymmetric reward blocks, we found that neurons medial prefrontal cortex male mice represented additive combination expectations choices. The inputs choices...
Vision is mediated by a set of hierarchically organized cortical areas that represent information at different levels complexity. Peripheral visual simple image-level features such as oriented edges, textures and motion energy. Central the semantic categories objects scenes. Intermediate are thought to shape (such silhouette contours) critical for building up more complex representations from simpler features. However, because it difficult parametrize in natural photographs, most studies...
In a recent study from our laboratory (Kay et al., Nature 2008, v.452, 352–355) we showed that brain activity measurements could be used to identify which specific static natural image was seen by an observer, even if the selected at random database consisting of thousands such images. Here demonstrate identification continuous time-varying movies measurements. We fMRI measure human observers while they watched continuous, movies. describe how stimuli are mapped onto measured in early visual...
