When I first started teaching rats to
0:01
drive cars, I never dreamed that those
0:04
little rodents would steer me toward a
0:06
surprisingly big discovery, a lesson
0:08
about the importance of joy in our
0:10
lives. We originally trained them to
0:13
drive to understand more about agency
0:15
and a sense of control and skill
0:17
acquisition on their brains and
0:19
behavior. And we so we taught them to
0:22
drive these rodent operated vehicles or
0:24
ROVs as we call them. and we found some
0:28
interesting findings and we published
0:30
it. But we quickly realized that this
0:32
this program of research had a lot of
0:35
potential for science outreach and this
0:37
is something that that we really need uh
0:39
today. So we decided to keep a group of
0:42
rats trained up on driving so that we
0:45
could continue with this science
0:47
outreach. And they became little rodent
0:49
celebrities. We trained them to exert
0:52
physical effort for Froot Loops. And
0:55
that's the currency of my lab. They love
0:57
Froot Loops. So, they work for Froot
0:58
Loops. So, we had about five weeks where
1:01
the animals had to connect physical
1:03
effort digging up those Froot Loops. But
1:06
could a neuroscientist study something
1:08
as complex as joy in a rat? And that's
1:12
what we did recently. We gave them a
1:14
choice of walking to the Froot Loop
1:16
tree, that's what they drive to, uh, in
1:18
a more efficient path, or they could
1:19
take a detour and backtrack and jump in
1:22
the car and drive to the rewards. and I
1:25
couldn't wait to see what they would do.
1:27
And what we found was a majority of the
1:29
animals did indeed uh backtrack, take a
1:33
tour, and jump into the car and drive to
1:36
their Froot Loop rewards.
1:39
Uh and if if you saw a human jumping in
1:42
the background, that was me uh jumping
1:45
for joy, seeing rats choose pleasure or
1:48
fun over efficiency. I taught rats to
1:51
drive cars, but but they taught me to
1:54
enjoy the
