[PDF][PDF] Phosphatidylserine exposure controls viral innate immune responses by microglia

Y Tufail, D Cook, L Fourgeaud, CJ Powers, K Merten… - Neuron, 2017 - cell.com
Microglia are the intrinsic immune sentinels of the central nervous system. Their activation
restricts tissue injury and pathogen spread, but in some settings, including viral infection, this …

Active encoding of decisions about stimulus absence in primate prefrontal cortex neurons

K Merten, A Nieder - … of the National Academy of Sciences, 2012 - National Acad Sciences
Judging the presence or absence of a stimulus is likely the most basic perceptual decision.
A fundamental difference of detection tasks in contrast to discrimination tasks is that only the …

A labeled-line code for small and large numerosities in the monkey prefrontal cortex

A Nieder, K Merten - Journal of Neuroscience, 2007 - Soc Neuroscience
How single neurons represent information about the magnitude of a stimulus remains
controversial. Neurons encoding purely sensory magnitude typically show monotonic response …
