We had a very fun session titled Teaching Brain Fitness in Your Community at an American Society on Aging (ASA) conference for health professionals a couple of weeks ago. Full house, with over 60 attendants and very good participation, showing great interest in the topic. I can’t wait to see the evaluations.

These are some of the resources I promised as a follow-up, which can be useful to everyone interested in our field:

Alvaro and I had the good fortune to attend a great conference last week called Learning & The Brain: Enhancing Cognition and Emotions for Learning. It was a fascinating mix of neuroscientists and educators talking with and listening to each other. Some topics were meant to be applied today, but many were food for thought – insight on where science and education are headed and how they influence each other.

Using dramatic new imaging techniques, such as fMRIs, PET, and SPECT, neuroscientists are gaining valuable information about learning. This pioneering knowledge is leading not only to new pedagogies, but also to new medications, brain enhancement technologies, and therapies…. The Conference creates an interdisciplinary forum — a meeting place for neuroscientists, educators, psychologists, clinicians, and parents — to examine these new research findings with respect to their applicability in the classroom and clinical practice.

Take-aways

• Humans are a mixture of cognition and emotion, and both elements are essential to function and learn properly
• Educators and public policy makers need to learn more about the brain, how it grows, and how to cultivate it
• Students of all ages need to be both challenged and nurtured in order to succeed
• People learn differently – try to teach and learn through as many different modalities as possible (engage language, motor skills, artistic creation, social interaction, sensory input, etc.)
• While short-term stress can heighten your cognitive abilities, long term stress kills you — you need to find balance and release
• Test anxiety and subsequent poor test results can be improved with behavioral training with feedback based on heart rate variability
• Dr. Robert Sapolsky is a very very enlightening and fun speaker
• Allow time for rest and consolidation of learned material
• Emotional memories are easier to remember
• Conferences like these perform a real service in fostering dialogues between scientists and educators

Continuing with the theme of a Week of Science sponsored by Just Science, we will highlight some of the key points in: Appelhans BM, Luecken LJ. Heart Rate Variability as an Index of Regulated Emotional Responding. Review of General Psychology. 2006;10:229–240.

Defining Heart Rate Variability
Effective emotional regulation depends on being able to flexibly adjust your physiological response to a changing environment.

“… heart rate variability (HRV) is a measure of the continuous interplay between sympathetic and parasympathetic influences on heart rate that yields information about autonomic flexibility and thereby represents the capacity for regulated emotional responding.”

“HRV reflects the degree to which cardiac activity can be modulated to meet changing situational demands.”

The sympathetic (SNS) and parasympathetic (PNS) branches of the autonomic nervous system (ANS) antagonistically influence the lengths of time between consecutive heartbeats. Faster heart rates, which can be due to increased SNS and/or lower PNS activity, correspond to a shorter interbeat interval while slower heart rates have a longer interbeat interval, which can be attributed to increased PNS and/or decreased SNS activity.

The frequency-based HRV analyses are based on the fact that the variations in heart rate produced by SNS and PNS activity occur at different speeds, or frequencies. SNS is slow acting and mediated by norepinephrine while PNS influence is fast acting and mediated by acetylcholine.
