The superior colliculus (SC) is a subcortical brain structure that is relevant for sensation,
cognition, and action. In nonhuman primates, a rich history of studies has provided …

Visual brain areas exhibit tuning characteristics well suited for image statistics present in our
natural environment. However, visual sensation is an active process, and if there are any …

Recent evidence suggests that microsaccades are causally linked to the attention-related
modulation of neurons—specifically, that microsaccades toward the attended location are …

Listening in noisy environments requires effort-the active engagement of attention and other
cognitive abilities-as well as increased arousal. The ability to separately quantify the …

Selective attention modulates neuronal activity in multiple brain regions, but the origins of
attention signals remain unclear. We show that, during a visual task requiring spatial …

Primate superior colliculus (SC) neurons exhibit visual feature tuning properties and are
implicated in a subcortical network hypothesized to mediate fast threat and/or conspecific …

The cortex modulates activity in superior colliculus via a direct projection. What is largely
unknown is whether (and if so how) the superior colliculus modulates activity in the cortex …

The causal roles of the frontal eye fields (FEF) and superior colliculus (SC) in spatial
selective attention have not been directly compared. Reversible inactivation is an …

Neurophysiological studies of covert visual attention in monkeys have emphasized the
modulation of sensory neural responses in the visual cortex. At the same time …

We introduce a decision model that interprets the relative levels of moment-by-moment
spiking activity from the right and left superior colliculus to distinguish relevant from …
