Over the course of six months, they brought their vision to life, feeding the friendly mice that kept them company the whole time.
Our previous studies with tamed wild rodents that were introduced into an empty arena (e.g. – [ 27, 44, 45]) revealed that they were relatively relaxed, and after a few minutes of exploration tended to rest in one place for extended periods, except for spiny mice that kept continuously on the move.
I am a man, not a mouse, and the only creature that kept me any company was our cat, Bernice, who is -- I say this with great affection -- a total moron.
So they tested whether mice dads with a mutation that kept their brain cells from responding to prolactin would grow new neurons as they nuzzled their newborn pups.
The floor of the traps are lined with a very sticky glue that keeps mice in place as soon as they run inside.
But the exercising mice also had an abundance of other new neurons that release GABA, a neurotransmitter that keeps other neurons from firing easily.
The correlation between the lack of torpor in Dbh −/− mice and the failure to suppress leptin levels during a fast led us to postulate that it was the inability to engage the SNS, activate β3 receptors and suppress leptin secretion from white adipose tissue during a fast that kept these mice from entering torpor.
We found that the activation of 5-HT2B receptors in mice that were kept under hypoxic conditions for several weeks triggered an increased PPE in the dura mater.
The study, published in The Journal of Neuroscience, looked at lab mice that were kept awake to replicate the kind of sleep loss common in modern life, through night shifts or long hours in the office.
We also determined plasma insulin and glucose levels in mice that were kept on a high-fat diet for 16 weeks.
