BUFFALO (US) — The brains of socially isolated animals make less myelin, the critical material that wraps the axons of neurons. The researchers say the findings, reported in the journal Nature Neuroscience, indicate that neurons aren’t the only brain structures that undergo changes in response to an individual’s environment and experience. The paper notes that changes in the brain’s white matter, or myelin, have been seen before in psychiatric disorders, and demyelinating disorders have also had an association with depression. Recently, myelin changes were also seen in very young animals or adolescents responding to environmental changes. “This research reveals for the first time a role for myelin in adult psychiatric disorders,” says Karen Dietz, a research scientist in pharmacology and toxicology in the University at Buffalo School of Medicine and Biomedical Sciences. Myelin allows neurons to signal effectively. Dietz did the work while a postdoctoral researcher at Mt.

Isolation and Loneliness | Psychalive “Why Do I Feel Isolated?” How to Understand and Overcome Loneliness and Isolation Human beings are naturally social animals. When we find ourselves becoming isolated, we should take that as a warning sign that we are turned against ourselves in some basic way. If not already there, we are on a path toward feeling bad, lonely, introverted or even depressed. Why We Start Feeling Isolated When we start feeling isolated, we may have thoughts of not belonging or of feeling rejected by others. How to Cope with with Feeling Alone Feeling lonely can trigger voices that we are unloved or unlikeable. Your critical inner voice can generate self-fulfilling prophecies. How the Critical Inner Voice Leads Us to Feel Lonely and Isolated When it feelings of comes to isolation, the voice can be an especially complicated and strategic enemy. Overcoming Feelings of Isolation No matter what their source, voices that you are unlikeable are much harder to accept when you’re around people who like you.
Who Knows What Youhavedownloaded.com? You may have never heard of youhavedownloaded.com, but if you recently grabbed movies, music or software from online file-trading networks, chances are decent that the site has heard of you. In fact, you may find that the titles you downloaded are now listed and publicly searchable at the site, indexed by your Internet address. In many ways, the technology behind the site merely recreates in a publicly searchable way what the entertainment industry has been doing for years: It tracks and records information that users share when they download and upload files on public peer-to-peer file-trading networks. So far, youhavedownloaded.com has recorded more than 50 million unique Internet addresses belonging to file-sharing users. Youhavedownloaded.com offers only limited information about its founders. Ter-Saakov said he believes youhavedownloaded.com indexes about 20 percent of the file-sharing activity on the Internet. The database has some serious limitations.
The Evolution of Privacy on Facebook About Facebook is a great service. I have a profile, and so does nearly everyone I know under the age of 60. However, Facebook hasn't always managed its users' data well. In the beginning, it restricted the visibility of a user's personal information to just their friends and their "network" (college or school). Over the past couple of years, the default privacy settings for a Facebook user's personal information have become more and more permissive. This blog post by Kurt Opsahl at the the EFF gives a brief timeline of Facebook's Terms of Service changes through April of 2010. Let me be clear about something: I like Facebook. Data The data for this chart was derived from my interpretation of the Facebook Terms of Service over the years, along with my personal memories of the default privacy settings for different classes of personal data. I welcome data corrections, so please leave a comment below if you have better numbers to share. Types of Personal Data Audiences Implementation About me
The Neuron It is clear that most of what we think of as our mental life involves the activities of the nervous system, especially the brain. This nervous system is composed of billions of cells, the most essential being the nerve cells or neurons. There are estimated to be as many as 100 billion neurons in our nervous system! spinal cord neuron A typical neuron has all the parts that any cell would have, and a few specialized structures that set it apart. Neurons have a large number of extensions called dendrites. One extension is different from all the others, and is called the axon. Longer axons are usually covered with a myelin sheath, a series of fatty cells which have wrapped around an axon many times. At the very end of the axon is the axon ending, which goes by a variety of names such as the bouton, the synaptic knob, the axon foot, and so on (I do not know why no one has settled on a consistent term!). axon endings The action potential Types of Neurons 1. 2. 3.
"Anonymized" data really isn't—and here's why not The Massachusetts Group Insurance Commission had a bright idea back in the mid-1990s—it decided to release "anonymized" data on state employees that showed every single hospital visit. The goal was to help researchers, and the state spent time removing all obvious identifiers such as name, address, and Social Security number. But a graduate student in computer science saw a chance to make a point about the limits of anonymization. Latanya Sweeney requested a copy of the data and went to work on her "reidentification" quest. At the time GIC released the data, William Weld, then Governor of Massachusetts, assured the public that GIC had protected patient privacy by deleting identifiers. Boom! Such work by computer scientists over the last fifteen years has shown a serious flaw in the basic idea behind "personal information": almost all information can be "personal" when combined with enough other relevant bits of data. Don't ruin me There are approaches that can reduce problems.
The Hidden Brain Sitting in a darkened lab at the National Institutes of Health in 1999, my colleague Beth Stevens and I prepared to send a mild electric current through fetal mouse neurons in a cell culture. We were using a new microscope technique that would let us see electrical activity as a bright fluorescence emitted from a dye we had added to the culture, and we were hoping to find out if another kind of cell common in the nervous system would react in some way—Schwann cells, odd-looking cells that fabricate insulation around neurons. We didn’t really expect them to; Schwann cells cannot communicate electrically. I flipped the switch. The neurons immediately glowed. But then the Schwann cells began to glow as well. The most mysterious substance on earth is the stuff between your ears, and much of the intrigue exists because many long-held beliefs about how the brain works have turned out to be wrong.

The Basics of C Programming" The previous discussion becomes a little clearer if you understand how memory addresses work in a computer's hardware. If you have not read it already, now would be a good time to read How Bits and Bytes Work to fully understand bits, bytes and words. All computers have memory, also known as RAM (random access memory). For example, your computer might have 16 or 32 or 64 megabytes of RAM installed right now. RAM holds the programs that your computer is currently running along with the data they are currently manipulating (their variables and data structures). float f; This statement says, "Declare a location named f that can hold one floating point value." While you think of the variable f, the computer thinks of a specific address in memory (for example, 248,440). f = 3.14; The compiler might translate that into, "Load the value 3.14 into memory location 248,440." There are, by the way, several interesting side effects to the way your computer treats memory. s:t 1:5 2:2 3:3 4:4 5:5 u = 5
