Equipment question for those of you doing #twophoton imaging: anyone using a fixed wavelength laser from Axon / Toptica / Spark Lasers? Any recommendations / horror stories would be most welcome, as would boosts. I really don't want to ask over there. Maybe @MatteoCarandini @sls? Thx!

If you have no idea what I'm talking about:

> The ecology of fear, the idea that the presence of a predator causes a cascade of ecological effects across a landscape, is a fundamental concept in wildlife ecology. In recent years, ecologists have come to appreciate how much animals, even apex predators, fear humans, with myriad effects on animal behaviors and, in turn, ecosystems.

Ecologist Asia Murphy writes about humans' role in the "ecology of fear" and the implications for wildlife management & conservation: https://www.americanscientist.org/article/a-landscape-of-fear-of-humans
