and psychology is cool

This is a picture of a human brain that is entirely smooth – free of the ridges and folds so characteristic of our species’ most complex organ. The patient had a rare condition called agyria; a lack of gyri and sulci, the ridges and folds formed by the normally wrinkled cerebral cortex. This disorder often leads to death before the age of ten, and can cause muscle spasms, seizures and a range of learning difficulties due to the considerably reduced surface area of the brain.

This picture shows the architecture of white matter in your brain.

The nervous system is made up of two types of matter; white and grey. They get their colour from when the axons are covered in a fatty white coloured substance called myelin.
Essentially, the grey matter is composed of the neuron’s cell bodies whilst white matter is composed of the myelinated axons which connects areas of grey matter together.
It can be compared to a computer network; the grey matter as the computers, whereas the white matter represents the network cables connecting the computers together.

This optical illusion shows how strongly the context of a visual scene influences what we see, and how this context can sometimes mislead us. The three people in the picture are exactly the same size. However, our brain judges the size of an object based on its perceived distance. The person at the front seems to be further away and therefore appears larger.

You have two humans, two individuals, who are going through a ritual. They are sitting at a table. They’re absolutely silent. They’re making no eye contact, and they do nothing more physically taxing than every now and then, one of them picks up their hand and moves a little piece of wood on the table. And if these happen to be the right two individuals in the middle of a chess grandmaster tournament, these people are maintaining blood pressure for six hours running that you only see in a marathon runner. These people are going through thousands of calories a day doing nothing more than thinking. (x)

It has only been 4 days since I started Criminal Minds and I’m already on season 3.

Things I know so far:

• JJ is hot too and her hair makes me jealous
• Psychology is so cool
• I just really really love Reid

Despite possessing relatively few neurons — around 100,000 — the fruit fly brain is still complex enough to produce many different behaviors, including feeding, mating, and sleeping. To figure out how their brains produce these behaviors, scientists labeled neurons that release the neurotransmitter serotonin and observed how the cells connect to each other. The image above shows these cells and their elaborate branches (dendrites) that receive signals from other neurons. Scientists can even turn these cells on and off to test how that changes the fly’s behavior. This research may help uncover how our own brain circuits determine behavior.
