A Familiar Brain Pattern?

In an interesting coincidence, the Rapid Eye Technology (RET) eye directing device (called a wand) is moved in a hexagonal 3D pattern just in front of the face - a pattern that due to its spacial character may be very familiar to the aforementioned part of the brain.

In an interesting coincidence, the Rapid Eye Technology (RET) eye directing device (called a wand) is moved in a hexagonal 3D pattern just in front of the face – a pattern that due to its spacial character may be very familiar to the aforementioned part of the brain.

University College London researchers have discovered that the brain lays out a grid of cells that represent a map of spacial orientations and locations in space. That in itself may not be any big news to most readers – “so what?” This grid has been known to exist in mice since 2005.

Well, the cool thing is that this 3D grid within the hippocampal formation and associated brain areas, now discovered to exist in humans as well, forms triangles in hexagonal formations – sort of like a honeycomb. Study co-author Dr Caswell Barry said: “It is as if grid cells provide a cognitive map of space. In fact, these cells are very much like the longitude and latitude lines we’re all familiar with on normal maps, but instead of using square grid lines it seems the brain uses triangles.”

In an interesting coincidence, the Rapid Eye Technology (RET) eye directing device (called a wand) is moved in a hexagonal 3D pattern just in front of the face – a pattern that due to its spacial character may be very familiar to the aforementioned part of the brain. Further, the signals flowing through the brain from eyes to visual cortex stop off for an emotional load at the hypothalamus which is attached to the memory-gating hippocampus – the seat of this honeycomb-like spacial mapping grid.

Research team leader, Professor Neil Burgess, commented, “…grid cells may help us to find our way to the right memory as well as finding our way through our environment. These brain areas are also amongst the first to be affected by Alzheimer’s disease which may explain why getting lost is one of the most common early symptoms of this disease.”

Guided Imagery Enhances Healing

According to the January issue of Mayo Clinic Health Letter, research shows that guided imagery helps patients use the full range of the body’s healing capacity. Guided imagery is more than listening to relaxing sounds – it’s a learning process to listen to someone’s voice, relax the breathing and consciously direct the ability to imagine. The effect of guided vivid imagery sends a message to the emotional control center of the brain. From there, the message is passed along to the body’s endocrine, immune and autonomic nervous systems. These systems influence a wide range of bodily functions, including heart and breathing rates and blood pressure.

Guided imagery has been shown to benefit patients by:

– Reducing side effects from cancer treatment

– Reducing fear and anxiety prior to surgery. Mayo Clinic studies have shown that surgery patients who participated in two to four guided imagery sessions required less pain medication and left the hospital more quickly than those who hadn’t used imagery.

– Managing stress

– Managing headaches. Studies at the Mayo Clinic have shown that guided imagery may aid in reducing the frequency of migraine headaches as effectively as taking preventive medications.

Time for a Good Nap?

napping.jpgHere’s a great exercise for self improvement! According to new research by Prof. Avi Karni and Dr. Maria Korman of the Center for Brain and Behavior Research at the University of Haifah, a ninety minute daytime nap helps speed up the process of long term memory consolidation. Now that is a self-help regimen I can get on board with!

“We still don’t know the exact mechanism of the memory process that occurs during sleep, but the results of this research suggest the possibility that it is possible to speed up memory consolidation, and in the future, we may be able to do it artificially,” said Prof. Karni.

Now that’s what I’m talkin’ ’bout! Artificial sleep! (What? Like hypnosis or Rapid Eye Technology?!!)

In the study, the group that slept in the afternoon showed a distinct improvement in their task performance by that evening, as opposed to the group that stayed awake, which did not exhibit any improvement. Following an entire night’s sleep, both groups exhibited the same skill level. “This part of the research showed that a daytime nap speeds up performance improvement in the brain. After a night’s sleep the two groups were at the same level, but the group that slept in the afternoon improved much faster than the group that stayed awake,” stressed Prof. Karni.

A second experiment showed that another aspect of memory consolidation is accelerated by sleep. It was previously shown that during the 6-8 hours after completing an effective practice session, the neural process of “how” memory consolidation is susceptible to interference, such that if, for example, one learns or performs a second, different task, one’s brain will not be able to successfully remember the first trained task. However, when a group of participants was allowed a 90 minute nap between learning the first set of movements and the second, they did not show much improvement in the evening, but on the following morning these participants showed a marked improvement of their performance, as if there had been no interference at all.

“This part of the study demonstrated, for the first time, that daytime sleep can shorten the time “how to” memory becomes immune to interference and forgetting. Instead of 6-8 hours, the brain consolidated the memory during the 90 minute nap,” explains Prof. The elucidation of the actual mechanisms involved, say the researchers, could enable the development of methods to accelerate memory consolidation in adults and to create stable memories in a short time.

Until then, if you need to memorize something quickly or if your schedule is filled with different activities that require learning “how” to do things, it may be worthwhile to find the time for an afternoon nap. Or you could learn self-hypnosis or Rapid Eye Technology (RET)

Chocolate For Stress?

Dark chocolate - good for stress? Yes!

Dark chocolate – good for stress? Yes! Good for you? Maybe not so much.

Maybe. Maybe not!

A recent article by the American Chemical Society (ACS) purports to extol the virtues of dark chocolate as a possible cure for stress. Apparently there is some substance to their study as it is getting plenty of press. Maybe that’s because we Westerners do like chocolate – and having a report that substantiates our appetite for the sweet confection adds to its reasonableness as a snack for us stressed-out folks.

Although it is nice that 1.4 oz of dark chocolate a day can significantly reduce stress over a two week period, it’s also true that “nobody can each just one!”

Let’s face it, some of us like chocolate A LOT – so much so that we might find it difficult to cut back to 1.4 oz per day!

I think it’s a bit early to start patting ourselves on the back for eating what is good for us each time we reach for the bonbons.

Synaesthesia Estimated in 1 in 1000

Synaesthesia is a neurologically-based phenomenon in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway.

Most people with synaesthesia are not aware they are synaesthetes and feel certain about the way they perceive things: they think the way they experience the world is the way everyone experiences it. But, when they realize that something is not quite "right," they become disappointed or afraid – many hide it or pretend to perceive as others around them do – "faking it."

The research field has grown from grapheme-color synaesthesia to include other forms of synaesthesia in which flavors are evoked by music or words (lexical-gustatory synaesthesia), space structures by time units, colors by music, etc.

Surprising as it may seem, there are people who can smell sounds, see smells, or hear colors. Actually, all of us at some point in our lives have had this ability – some authors affirm that it is common in newborns.

In the department of Experimental Psychology and Physiology at the University of Granada, a research group is carrying out pioneer work in Spain on the systematic study of synaesthesia and its relation with perception and emotions. Professor Juan Lupiáñez Castillo and Alicia Callejas Sevilla have devoted many years to the study of this unknown but interesting phenomenon, which affects approximately one person out of every thousand. Many of these people do not even know that they are synaesthetes, as they think they perceive the world normally.
