This study investigates how transient noradrenergic signals from the locus coeruleus influence perceptual computation by analyzing their temporal effects on behavior during a visual task.

The paper shows that intensity-weighted normalization explains variability in neuronal responses in macaque MT and accounts for spontaneous activity as excitatory drive.

This study shows that superior colliculus activity correlates with perceptual sensitivity during visual spatial attention, independent of decision and motor biases.

The paper examines normalization in mouse visual cortex using calcium imaging and electrophysiology, finding similar normalization strength distributions to cats and macaques but slightly weaker on average.

The paper uses reverse correlation analysis to show that SC and V1 spiking contribute differently to contrast and luminance detection in mice.

The paper finds that humans are more sensitive to increases than decreases in motion coherence of random dot stimuli, suggesting cortical circuits prioritize spike rate increases.

The paper shows that locus coeruleus norepinephrine enhances visual attention by selectively improving sensory discrimination in non-human primates without affecting motor processing.

The paper uses optogenetic white noise stimulation to determine how timing of V1 spikes influences visual detection behavior in mice.

This study investigates how attentional selectivity and intensity modulate neuronal responses in visual area V4, showing their effects are consistent regardless of motivational context.

The paper isolates attentional intensity and its single-trial dynamics in monkey visual area V4 during an orientation discrimination task, showing it is distinct from spatial selectivity and other factors.

The paper shows that perceptual detection in mice depends on integrating spike counts in V1 rather than instantaneous spiking changes.

The paper shows that different inhibitory interneurons in the visual cortex of mice have distinct effects on contrast perception, with PV and SST impairing and VIP improving detection.
