Not Strictly Human-centric: Different forms of Language Contact

ms-sabrine:

When we talk about ‘language contact’, we are referring to the ways in which different languages interact with one another within the societies speaking the separate languages. How the engage with one another and influence one another. Below will be a brief explanation of the…

neurolove:

Acetylcholine (ACh) is another neurotransmitter, best known for being the neurotransmitter that bridges the gaps between neurons and muscles. Unlike neurotransmitters acting upon other neurons, ACh has a 1:1 action on muscles. One action potential causes a muscle contraction, no need for build up (like with EPSPs and IPSPs).  The amount of ACh released and the pattern in which it is released will determine how much the muscle contracts and for how long.
I found this great infographic online to show the process of ACh on muscle contraction from here.  Nicotine, the addictive substance in cigarettes, acts upon ACh receptors. ACh also has its own actions in the brain, which I will talk about another time.

A catcall is entirely about reminding you that you are not yours. The purity myth is entirely about reminding you that you are not yours. The fetishization of female purity in a world where catcalls are an acceptable form of communication telegraphs one thing very clearly:

“Women, stop sexualizing yourselves—that’s our job, and you’re taking all the fun out of it.”

The sexualization of women is only appealing if it’s nonconsensual. Otherwise it’s “sluttiness,” and sluttiness is agency and agency is threatening.

I Did This on Purpose so I Love it!: Dear Everyone Who Doesn't Do Science,

thestudyofmettle:

The question is rarely nature vs. nurture. Human beings don’t mature in a vacuum. Just because something has a genetic component doesn’t mean it’s God’s gospel truth. Socialization (how we’re raised, the kinds of ideas we’re exposed to, our value sets) and our environment…
