This review focuses on covert attention and how it alters early vision. I explain why attention
is considered a selective process, the constructs of covert attention, spatial endogenous and …

Rewards are crucial objects that induce learning, approach behavior, choices, and
emotions. Whereas emotions are difficult to investigate in animals, the learning function is …

Environmental stimuli and objects, including rewards, are often processed sequentially in
the brain. Recent work suggests that the phasic dopamine reward prediction-error response …

An analysis of response latencies shows that when an image is presented to the visual
system, neuronal activity is rapidly routed to a large number of visual areas. However, the …

Over the past decade fMRI researchers have developed increasingly sensitive techniques
for analyzing the information represented in BOLD activity. The most popular of these …

Despite great efforts over several decades, our best models of primary visual cortex (V1) still
predict spiking activity quite poorly when probed with natural stimuli, highlighting our limited …

The response of cortical neurons to a sensory stimulus is shaped by the network in which
they are embedded. Here we establish a role of parvalbumin (PV)-expressing cells, a large …

The directness and vivid quality of conscious experience belies the complexity of the
underlying neural mechanisms, which remain incompletely understood. Recent work has …

The cortical visual system consists of many richly interconnected areas. Each area is
characterized by more or less specific receptive field tuning properties. However, these …

We studied the steady-state orientation selectivity of single neurons in macaque primary
visual cortex (V1). To analyze the data, two measures of orientation tuning selectivity …
