Surfing and Autism

Tuesday, July 14th, 2009

Autism is a pervasive developmental disorder that includes a wide array of symptoms. We do not know the cause of autism and we have no cure. Much has been learned and autism is certainly no longer viewed as a single disorder or entity. The emotional strain on a family can be substantial, particularly when resistance to an emotional or loving attachment occurs.

I have been reading more about the positive effects of surfing on some children with autism. As I am not an expert in this area I want to be careful and inform the public that autism is not my area of specialization. However, I have now read several accounts of how a child suffering from autism has a type of “awakening” after some time in the water learning how to surf.

Obviously, the surfing I am describing involves one to one work with a trained surfer who has a gift of working with children suffering autism. It is also true that by these accounts that the first part of the experience can be difficult as the child experiences a natural fear of the ocean and strangers. It might be most difficult for the parents who are watching with great doubt.

The reports indicate that after a short period of time the child with autism not only relaxes, but begins to awaken to life and the surroundings in a way not seen prior to the surfing experience. It is not known why or how this occurs, but perhaps the child’s brain is literally overwhelmed with stimulation which helps to soothe and foster interaction with others in the immediate environment. One parent even described his child as being able to speak and connect in ways he thought was impossible.

Perhaps Mother Nature provides us with some treatments in her own way. The majesty of an ocean whose water fills 80% of our planet might have some answers for the brain. Maybe it is the movement, the energy, the sound, the rhythm. Even if we do not fully understand why, the fact that we have anecdotal evidence for surfing bringing some children with Autism to a new awakening is reason enough to ask more questions.

The Brain and Autopsy

Friday, July 10th, 2009

Neuropathologists can confirm clinical diagnoses at death by doing an autopsy. Such work can reveal the presence of markers characteristic of particular diseases. This might include neurofibrillary tangles and neuritic plaques indicating the presence of Alzheimer’s disease (AD) or stroke as examples.

The other interesting thing about autopsies of the brain is that the neuropathologist may uncover something peculiar about the person’s brain that can help to explain that person’s talent or brilliance in a particular activity. One example is Einstein’s brain that had a slightly different area of the parietal lobe relative to the rest of the population. This might help to explain his appreciation of space and numbers.

As I watched the recent funeral of Michael Jackson the most salient issue for me was the children. Like many, I hope and pray for their wellbeing and comfort. I have also noticed multiple articles in the media on determining cause of death in this case and the value of conducting an autopsy of the brain.

I understand the need to determine cause of death; however I am hopeful that any autopsy of the brain also sheds light on the brilliance and creative spirit of Michael. I wonder if the neuropathologist might discover some ideas within the folds and grooves of the brain that help all of us understand not only the brilliance of Michael, but of the human brain and our potential to create.

How about those Glial Cells

Thursday, July 2nd, 2009

For many years neurons have been considered the main act within the cerebral cortex, responsible for our thoughts, emotions, and movements. Of interest is the fact that neurons only account for about 10% of human brain cells. Glial cells that account for the other 90% of brain cells have typically been thought to carry a supportive role to the neurons.

An article in Forbes Magazine (July 13, 2009), however, suggests glial cells may be even  more important than neurons for treating neurodegenerative diseases such as Alzheimer’s, Parkinson’s, and stroke. Recent understanding of the brain now indicates glial cells with neurons play a critical role in brain development and brain function.

Medications on the market today do not work on glial cells. Ben Barnes, Chairman of the Neurobiology Department at Stanford University Medical School posits that one type of glial cells, the astrocytes, trigger the initial steps of destruction in brain diseases. As such, Dr. Barnes believes that by creating treatments that of the astrocytes can in turn save dying neurons.

If glial cells do indeed maintain a more critical role in the formation, function, and elimination of synaptic activity, plasticity, and creation of myelin sheath around the neuron, an entirely new approach to behavioral neuroscience will be born and with it, an entirely new treatment approach.

Please Speak into my Dominant Ear

Monday, June 29th, 2009

ear

The human brain has what is known as a dominant side and a non-dominant side. Dominance is determined by where language is processed and for the vast majority of humans we believe the dominant side is the left side or left hemisphere. Interestingly, we are not sure why the left side evolved to be dominant, but perhaps it had something to do with cave men and women using their right hands more often.

As language is processed primarily by most in the left hemisphere it is important to note that words are best processed when spoken into the right ear. The right ear processes information primarily using the left hemisphere while the left ear uses the right hemisphere.

A recent study found that words were more deeply processed when spoken into the person’s right ear. Therefore, if you want me to remember something for you please speak to me on my right side.

When Shopping is not Shopping

Wednesday, June 24th, 2009

womenandmenshopping

A typical and yet interesting reality is that most women enjoy shopping and most men do not. As one interested in human behavior this is a fascinating finding worthy of some curiosity. The explanation of the differences between the two genders regarding shopping might be found in a basic understanding of the human brain.

Shopping for a male brain is defined as going into a store or mall, selecting the item to be purchased, and getting out of the store as fast as possible. This behavior is task-based, something to be confronted and completed. The male brain operates primarily within the dominant hemisphere, a side of the brain that is task based.

Shopping for a female brain is both task based and process based. For example, a female can do the same thing a male does while shopping by getting the item and getting out. However, upon entering the doors of the mall, the female brain hears music in the background, smells cinnamon rolls baking in the distance, and appreciates the wonderful different colors and textures of the products throughout the store. This is the non-dominant side of the female brain functioning, something that is foreign to the male brain within the shopping mall.

It can be fun to watch the female and male brain try to work together as “shopping” behavior occurs together. Have you ever seen an otherwise happy couple get frustrated with each other in the mall? Perhaps a little understanding of the how and why behind the gender differences can help to make the next shopping trip a good one.

Emotional Eating

Monday, June 22nd, 2009

We eat for many different reasons some of which are not healthy. Food is necessary for humans to survive though consumption of food in advanced nations is really not based on survival. Early in our development we hunted and remained vigilant most of the day to gather and consume food for survival. Today, food is so available in many different forms that this primal instinct to eat for survival is gone.

Today, food is consumed to satisfy hunger, maintain a routine of three meals a day, and to cope with emotions of guilt, anxiety, sadness, boredom, low self esteem, anger, and loneliness. Emotional eating is probably never healthy and leads to other problems such as obesity, high blood pressure, high cholesterol, and diabetes. These problems in turn lead to increased risk for heart attack, stroke, and even dementia.

The only way to identify why you are eating is to remain conscious of your thoughts and feelings when you desire food. This will help you understand what is driving you to eat. Clearly we need to consume food for energy and function. However, most people over consume and do so on a subconscious basis. This unhealthy regimen can be addressed and transitioned to a healthy regimen of eating behavior only by becoming conscious of one’s thoughts prior to eating

Here are some activities to promote and stabalize emotional balance

The Brain: Attention & Concentration

Saturday, June 13th, 2009

Attention is the most basic and necessary function of the brain. The brain can attend to information from five sensory pathways. While a deeper level of processing is not necessary for attention to occur, it is also true that a deeper level of information processing cannot occur without normal attention. The brain stem and frontal lobe are thought to be important for basic attentional processing. The entire Cortex is likely involved to a degree with basic attention.

The 5 Major Brain Areas: Memory

Thursday, June 11th, 2009

The human brain is very complex and responsible for all behavior, and we are continually learning new information about how it operates. Behavioral and cognitive functions can be organized into five distinct domains to include : Memory,  Attention & Concentration, Language Skills, Visual & Spatial and Executive Functions (Logic & Reasoning).

Memory

Memory and new learning is a necessary and important function of the human brain. Our ability to live independently and to function normally is a direct result of a normal memory system. Our life story is built by encoding and retaining our daily experiences. Our personal identity is framed by our memory and ability to learn from these memories.

Memory and new learning begins with the Hippocampus, a critical structure in the middle temporal lobes of both hemispheres of the brain. This is the structure that enables learning and transition of new learning into a permanent storage site in the Cortex. The Hippocampus has the ability to generate new brain cells with stimulating environments, can be damaged with chronic stress, and is hit early by Alzheimer’s disease. Damage to the Hippocampus results in memory deficits.

The Power of Positive Thinking

Monday, June 8th, 2009

As we learn more about the power of the human brain it is more common to hear about ideas regarding our ability to guide our future, intuition, and premonition. Given that the brain is an electrical, magnetic, and chemical system we should not be too surprised by such ideas.

Research has already demonstrated the brain’s ability to move a cursor on a computer screen merely through thoughts. Other research indicates meditation can slow the progression of HIV and the military is presently working on communication between soldiers on the battle field that is essentially based on telepathy.

We are perhaps more accustomed to ideas such as mental focus, discipline, and attention. These mental qualities are perfected by athletes such as Tiger Woods and Michael Jordan to name a few. It is precisely these attributes that distinguish these professionals as superstars relative to the other great athletes. Can the human brain train to use these forces to guide their future and to derive positive outcomes?

My opinion is that the human brain can do anything so I certainly believe each of us has the ability to visualize and to increase the probability of our future being a good one. I believe we have the ability to imagine or dream and to focus our energies in a positive stream towards that goal. This is most likely quite foreign to most, but begin by developing more and more positive thoughts, visualize positive outcomes, and create energy around you and inside you that is positive. Take an inventory of what occurs in your life after you begin and sustain this mental process.

Happy Trails.

Music as medicine: Docs use tunes as treatment

Tuesday, June 2nd, 2009

Listen carefully and you’ll hear the same refrain at a rising number of hospitals. From Massachusetts General to the Mayo Clinic, patients are hearing the first strains of a harmonious movement — the infusion and inclusion of music in the treatment of ailments, from brain disorders to cancer. This goes beyond the psychological smile favorite songs can induce.

Doctors are increasingly studying — and employing — the physiological dance music does with the body’s neurons and blood-carrying cells.

Researchers explore how melodies can help regulate heart, boost hormones
