How Music Helps to Heal the Injured Brain Therapeutic Use Crescendos Thanks to Advances in Brain Science

Editor’s note: The use of music in therapy for the brain has evolved rapidly as brain-imaging techniques have revealed the brain’s plasticity—its ability to change—and have identified networks that music activates. Armed with this growing knowledge, doctors and researchers are employing music to retrain the injured brain. Studies by the authors and other researchers have revealed that because music and motor control share circuits, music can improve movement in patients who have suffered a stroke or who have Parkinson’s disease. Research has shown that neurologic music therapy can also help patients with language or cognitive difficulties, and the authors suggest that these techniques should become part of rehabilitative care. Future findings may well indicate that music should be included on the list of therapies for a host of other disorders as well.

 
The role of music in therapy has gone through some dramatic shifts in the past 15 years, driven by new insights from research into music and brain function. These shifts have not been reflected in public awareness, though, or even among some professionals.
Biomedical researchers have found that music is a highly structured auditory language involving complex perception, cognition, and motor control in the brain, and thus it can effectively be used to retrain and reeducate the injured brain. While the first data showing these results were met with great skepticism and even resistance, over time the consistent accumulation of scientific and clinical research evidence has diminished the doubts. Therapists and physicians use music now in rehabilitation in ways that are not only backed up by clinical research findings but also supported by an understanding of some of the mechanisms of music and brain function.
Rapid developments in music research have been introduced quickly into neurologic therapy (see sidebar) over the past 10 years. Maybe due to the fast introduction,  the traditional public perception of music as a ‘soft’ addition, a beautiful luxury that cannot really help heal the brain, has not caught up with these scientific developments.
But music can. Evidence-based models of music in therapy have moved from soft science—or no science—to hard science. Neurologic music therapy does meet the standards of evidence-based medicine, and it should be included in standard rehabilitation care.  Click anywhere in this sentence to continue reading...

Brain's Fear Center is Equipped With a Built-in Suffocation Sensor

..."It has been proposed that panic and anxiety disorders involve a suffocation alarm gone haywire," Welsh said. "Now, this work may shed some light on this well-known phenomenon and suggests strategies for further exploration."

The findings raise the possibility that some people may be more prone to anxiety disorders, including post-traumatic stress disorder, due to genetic variants they carry in components of this ASIC pathway. They also suggest that new therapeutic strategies for panic and anxiety might target changes in brain pH or the acid-sensing channels.  Click anywhere in this sentence to continue reading...

Neurons-How They Work

This video takes you on a short, yet very informative tour through the human brain. It goes in to good detail regarding electrical and chemical connections and their relationship with brain neurons.

How it feels to have a stroke

Neuroanatomist Jill Bolte Taylor had an opportunity few brain scientists would wish for: One morning, she realized she was having a massive stroke. As it happened -- as she felt her brain functions slip away one by one, speech, movement, understanding -- she studied and remembered every moment. This is a powerful story about how our brains define us and connect us to the world and to one another.

Amazing neurological expedition lead by V.S. Ramachandran MD PHD.

Psychological trauma is a type of damage to the psyche that occurs as a result of a traumatic event.

When that trauma leads to posttraumatic stress disorder, damage may involve physical changes inside the brain and to brain chemistry, which damage the person's ability to adequately cope with stress.
A traumatic event involves a single experience, or an enduring or repeating event or events, that completely overwhelm the individual's ability to cope or integrate the ideas and emotions involved with that experience. The sense of being overwhelmed can be delayed by weeks, years, even decades, as the person struggles to cope with the immediate circumstances. Trauma can be caused by a wide variety of events, but there are a few common aspects. There is frequently a violation of the person's familiar ideas about the world and of their human rights, putting the person in a state of extreme confusion and insecurity. This is also seen when people or institutions depended on for survival violate or betray or disillusion the person in some unforeseen way. Click anywhere in this sentence to continue reading...
