One of my mice has six toes :-O check it out
Did I just get ANOTHER P.E.W. pup???
Learn Basic Genetics with MisterMiceGuy
OMG – So Fluffy, Watch a Merle Texel Litter Grow
How do I know if my mouse pups are male or female
Lets compare the size difference between my micro mice and regularly sized mice
Lets Take a Peek at Some Black and White Mice
New: Merle Mouse Pups!
My second video talking about my new merle litter that I will be using to create my first set of MisterMiceGuy videos!
MisterMiceGuy Gets Started on Youtube
I’ve been wanting to make videos for a while but as it turns out making videos is really hard lol. But I am going to get started on my MisterMiceGuy channel were I will be talking about mouse breeding, animal behavior, genetics and more! Clearly I have a lot of work to do haha 🙂
Dissociation of learned helplessness and fear conditioning in Mice: a mouse model of depression
Researchers discuss that an important element of Helplessness is its “transituationality”. Meaning that Helplessness conditioned in one environment is generalizable to other situations. Researchers wanted to separate helplessness from conditioned fear by testing for transituationality.
They first conditioned mice with tail shocks to induce helplessness. Then after two days of shock conditioning the mice were placed into a shuttle box. Here they shocked the mice’s feet to see if they tried to escape to the non-shocking side of the shuttle box. If the mice escaped to the non-shocking side this would mean that the mice had not developed learned helplessness. If he mice did not attempt to escape the shocks this would indicate that they had developed helplessness via the tail shocks and it transferred to the shuttle box.
The researchers found that around 50% of the mice would escape to the non-shocking side The other 50% would not attempt to escape the shocks despite having never been conditioned in a shuttle box. This means that 50% of the mice developed learned helplessness that transferred from the tail shock conditioning. This research is important because the researchers devised away to separate the effects of conditioned fear from learned helplessness.
