Predictive coding theories of sensory brain function interpret the hierarchical construction of
the cerebral cortex as a Bayesian, generative model capable of predicting the sensory data …

Attention has been found to have a wide variety of effects on the responses of neurons in
visual cortex. We describe a model of attention that exhibits each of these different forms of …

Incoming sensory information is sent to the brain along modality-specific channels
corresponding to the five senses. Each of these channels further parses the incoming …

Visual area V4 is a midtier cortical area in the ventral visual pathway. It is crucial for visual
object recognition and has been a focus of many studies on visual attention. However, there …

Neurons in primary sensory cortex have diverse response properties, whereas higher
cortical areas are specialized. Specific connectivity may be important for areal …

Rabies viruses, negative-strand RNA viruses, infect neurons through axon terminals and
spread trans-synaptically in a retrograde direction between neurons. Rabies viruses whose …

Glycoprotein-deleted (ΔG) rabies virus is a powerful tool for studies of neural circuit
structure. Here, we describe the development and demonstrate the utility of new resources …

The common marmoset (Callithrix jacchus) has been valuable as a primate model in
biomedical research. Interest in this species has grown recently, in part due to the successful …

Optogenetics is the use of genetically coded, light-gated ion channels or pumps (opsins) for
millisecond resolution control of neural activity. By targeting opsin expression to specific cell …

Visual system circuitry, a canonical model system for the study of experience-dependent
development, matures before and following the onset of vision. Sensory experience or …
