Animal behavior is shaped by a variety of" internal states"—partially hidden variables that
profoundly shape perception, cognition, and action. The neural basis of internal states, such …

Daylight is ubiquitous and is crucial for mammalian vision as well as for non-visual input to
the brain via the intrinsically photosensitive retinal ganglion cells (ipRGCs) that express the …

INTRODUCTION Electrode arrays based on complementary metal-oxide semiconductor
silicon fabrication technology, such as Neuropixels probes, have enabled recordings of …

To increase computational flexibility, the processing of sensory inputs changes with
behavioural context. In the visual system, active behavioural states characterized by motor …

Vision is widely used as a model system to gain insights into how sensory inputs are
processed and interpreted by the brain. Historically, careful quantification and control of …

To produce consistent sensory perception, neurons must maintain stable representations of
sensory input. However, neurons in many regions exhibit progressive drift across days …

Pupil size is a widely used metric of brain state. It is one of the few signals originating from
the brain that can be readily monitored with low-cost devices in basic science, clinical, and …

Simultaneous recordings from hundreds or thousands of neurons are becoming routine
because of innovations in instrumentation, molecular tools, and data processing software …

The superior colliculus is a midbrain structure that plays important roles in visually guided
behaviors in mammals. Neurons in the superior colliculus receive inputs from retinal …

The action potential is a fundamental unit of neural computation. Even though significant
advances have been made in recording large numbers of individual neurons in animal …
