Yeah.
We just think of them as neighbors, as fellow inhabitants of the environment in which we live.
A lot of times we end up in conflict with bears, deer, et cetera, rats, because we are providing them food, either accidentally or on purpose.
One of the things I learned in my reporting on white-tailed deer and bear in particular is how many people feed these animals on purpose.
And I would just like to say, please don't do that.
that is actually going to promote conflict and it's not actually acting out of the animal's best interests.
We do that because we want it.
We want that Disney princess moment, right, of the deer eating out of our hand or something.
And real coexistence with wildlife means that's probably a bad idea.
Yeah, no worries.
Thank you so much.
These are really good questions.
Like right all the way down to DNA.
If you want an animal to press a lever and receive a drug, a rat is generally the better choice.
Especially now with the advent of CRISPR technologies that allow us to alter adult genetics and fetal genetics, we established that first in mice. We can do it in rats now, but it's very, very well established in mice. And so that really took off.
Yes. In my experience, rats are better for self-administration of drugs. So if you want an animal to press a lever and receive a drug, a rat is generally the better choice because of size. Because mice are so small, it's really hard to make a lever that they can press well enough.
I studied primarily drugs of abuse in graduate school, and then I studied antidepressants for my postdoc.
Ritalin, cocaine, methamphetamine, ecstasy, alcohol, Prozac. If you want to be really nerdy about it, I studied the dopamine-serotonergic interactions in the ventral tegmental area nucleus accumbens circuit of the mouse brain.
Yeah. So I was interested in drugs that primarily targeted dopaminergic systems.
I was interested in chronic high-dose administration of methylphenidate, which is Ritalin. You know, humans, we give people Ritalin starting at very young ages. So I was very interested in what chronic exposure to these drugs means for the brain as you get older. Does it make you more or less susceptible to drug addiction?
