Love and Stockholm Syndrome
Love and Stockholm Syndrome: The Mystery of Loving an Abuser by Joseph M. People are often amazed at their own psychological conditions and reactions. In clinical practice, some of the most surprised and shocked individuals are those who have been involved in controlling and abusive relationships. On August 23rd, 1973 two machine-gun carrying criminals entered a bank in Stockholm, Sweden. After their rescue, the hostages exhibited a shocking attitude considering they were threatened, abused, and feared for their lives for over five days. While the psychological condition in hostage situations became known as “Stockholm Syndrome” due to the publicity – the emotional “bonding” with captors was a familiar story in psychology. Abused Children Battered/Abused Women Prisoners of War Cult Members Incest Victims Criminal Hostage Situations Concentration Camp Prisoners Controlling/Intimidating Relationships Every syndrome has symptoms or behaviors and Stockholm Syndrome is no exception.

Brain Information, Facts -- National Geographic
Making sense of the brain's mind-boggling complexity isn't easy. What we do know is that it's the organ that makes us human, giving people the capacity for art, language, moral judgments, and rational thought. It's also responsible for each individual's personality, memories, movements, and how we sense the world. All this comes from a jellylike mass of fat and protein weighing about 3 pounds (1.4 kilograms). It is, nevertheless, one of the body's biggest organs, consisting of some 100 billion nerve cells that not only put together thoughts and highly coordinated physical actions but regulate our unconscious body processes, such as digestion and breathing. The brain's nerve cells are known as neurons, which make up the organ's so-called "gray matter." The cerebrum is the largest part of the brain, accounting for 85 percent of the organ's weight. The cerebrum has two halves, or hemispheres. Movement and Balance The diencephalon is located in the core of the brain.

Innovative Brain Imaging Combines Sound And Light
Lihong Wang uses light and sound to create highly detailed images of the living brain.

Chris Nickels for NPR Lihong Wang creates the sort of medical technology you'd expect to find on the starship Enterprise. Wang, a professor of biomedical engineering at Washington University in St. "It's really about turning some of these ideas that we thought were science fiction into fact," says Richard Conroy, who directs the Division of Applied Science & Technology at the National Institute of Biomedical Imaging and Bioengineering. Wang's ultimate goal is to use a combination of light and sound to solve the mysteries of the human brain. Wang describes himself as a toolmaker. "We want to conquer the brain," Wang says. Current brain-imaging techniques such as functional MRI or PET scans all have drawbacks. Wang's initial idea was to use light.

Controlling RNA in living cells
MIT researchers have devised a new set of proteins that can be customized to bind arbitrary RNA sequences, making it possible to image RNA inside living cells, monitor what a particular RNA strand is doing, and even control RNA activity. The new strategy is based on human RNA-binding proteins that normally help guide embryonic development. The research team adapted the proteins so that they can be easily targeted to desired RNA sequences. “You could use these proteins to do measurements of RNA generation, for example, or of the translation of RNA to proteins,” says Edward Boyden, an associate professor of biological engineering and brain and cognitive sciences at the MIT Media Lab. “This could have broad utility throughout biology and bioengineering.” Unlike previous efforts to control RNA with proteins, the new MIT system consists of modular components, which the researchers believe will make it easier to perform a wide variety of RNA manipulations.

New cryopreservation procedure wins Brain Preservation Prize

The myelinated axon shows excellent preservation. (credit: Robert L. McIntyre and Gregory M. The Brain Preservation Foundation (BPF) has announced that a team at 21st Century Medicine led by Robert McIntyre, PhD., has won the Small Mammal Brain Preservation Prize, which carries an award of $26,735. The Small Mammalian Brain Preservation Prize was awarded after the determination that the protocol developed by McIntyre, termed Aldehyde-Stabilized Cryopreservation, was able to preserve an entire rabbit brain with well-preserved ultrastructure, including cell membranes, synapses, and intracellular structures such as synaptic vesicles (full protocol here). First preservation of the connectome Winning the award also required that the procedure be published in a peer reviewed scientific publication.
If We’re Going to Talk About Brainwaves, We Should Know What They Are
Brainwaves come up in conversation a lot, especially when you’re talking about mindfulness, creativity, falling asleep, and other processes we’re trying to understand. But do you know what a brainwave actually is? It’s kind of surprising. Most of us have heard about at least some of these major brainwave categories (there are sub-categories, too): gamma brainwaves — 40 to 100 cycles, or Hertz (Hz) per second, associated with learning memory, and information processingbeta brainwaves — 12 to 40 Hz, associated with conscious thought and logical thinkingalpha brainwaves — 8 to 12 Hz, associated with light daydreaming and relaxationtheta brainwaves — 4 to 8 Hz, associated with deeper daydreaming and sleepdelta brainwaves — 0 to 4 Hz, associated with deep relaxation and restorative deep sleep, also with unconscious body functions ZEISS, a rat neuron An electroencephalogram, or EEG, can measure this electricity through electrodes temporarily stuck to a subject’s scalp.
