Midterms & Carnival of Homeschooling 63

The Carnival of Homeschooling is up over at Tami's Blog!

It looks to be very good, with articles about homeschooling in general, math, science, social studies, and more!

Check it out!

Unfortunately, I will be checking out the Carnival a few articles at a time during breaks in studying. See the molecule to the right? That's Serotonin. It is a neurotransmitter important to learning and memory--among other things.

I will rely much on serotonin for the rest of this week.

I just finished writing for two hours straight for my Special Education Law class. There was some information to remember about the purpose of law and human rights, but most of the test covered IDEA 2004 and two SCOTUS cases, which we had in front of us. I tabbed my statute in order to find information more quickly.
Now my hand hurts!

Unfortunately, I am not done yet!
I still have Neurobiology to go. That test is on Friday and there will be no notes or diagrams allowed.

And for this kind of class, you must know everything covered in the last 4 weeks of lecture.

Today, I spent some time reviewing G-Protein receptors (pictured to the left) and how they work.

Colorful, aren't they?

They are important in second-messenger signaling in the cell. A neurotransmitter attaches to the receptor outside the cell and this causes the receptor protein to change shape and release the alpha subunit of the G-protein, which in turn causes the phosphorilization of a protein kinase, and activates a cascade of messengers in the cell that can in turn activate a gated channel in the membrane, or activate or inhibit neurotransmitter vesicle movement, or even enter the nucleus and change gene expression.

So I remember something, but I've got to go back and memorize specific pathways and the conformation of specific protein kinases and so forth!

Somebody remind me of exactly why I am doing this to myself!

I have three full days of studying ahead of me before my Spring Break begins at 5 PM MST on Friday.

You are doing it because learning is great and because you would be bored if your mind wasn't fully stimulated. Serotonin is also one of the regulators of depression so keep studying Elisheva. Keep your active neural pathways alive and well maintained.

I'm going away for a few days: a quick and unplanned trip to Brisbane. I'll catch up on your blog with my return.
