Anxiety is ancient – how crayfish resemble vertebrates
Fear is something we all know. It changes our behavior: we freeze, try to escape, or respond with aggression. Fear can also cause anxiety, which is a more complex phenomenon.
How zebrafish are changing neuroscience
Zebrafish. This little fish is a vertebrate, and a relatively complex one. Looking at the major neurotransmitters and hormones that are investigated in neuroscience, they are as good of a model as many mammalian species.
How to easily automate the elevated plus maze test
Anxiety. It is nature’s way to keep us out of harm’s way, so it is a useful emotion. At times, though, it can also be overwhelming. For some, it gets out of control, irrational, and even disabling.
Zebrafish research: behavioral differences between wild-type strains
Often in animal research, animals with a certain genetic alteration are compared to a “wild-type”. One might assume that there is no differences between wild-types, but many different strains of wild-type animals are used.
The effect attention training has on social anxiety disorder
It is inevitable that everyone will experience anxiety and stress at some point in their lives. Most individuals are able to move past their stress with just a little bit of effort.
