Brain Plasticity & Early Intervention: “Neurons that fire together, wire together”

February 10, 2022 by Ronit Molko Leave a Comment


The following is based on a conversation Ronit Molko, Ph.D., BCBA-D and Dr. Evian Gordon, Chairman and CEO of Brain Resource.

The development of the brain is a fascinating and essential aspect of child development. The science behind the brain provides parents and practitioners valuable insight as to why early intervention is important for individuals with autism and other developmental disabilities.

At birth, a child’s brain is a work in progress. It develops as they experience the world through seeing, hearing, tasting, touching, and smelling the environment. The natural, simple, loving encounters with adults that occur throughout the day, such as a caregiver singing, smiling, talking, and rocking their baby, are essential to this process. All of these encounters with the outside world affect the child’s emotional development and shape how their brain becomes wired and how it will work.

The experiences of babies have long-lasting effects on their ability to learn and regulate their emotions. When there is an absence of appropriate teaching and learning opportunities in the baby’s environment, the brain’s development can be affected and there are more likely to be sustained negative effects. Conversely, if we can provide ample learning opportunities, we can facilitate brain development. Let’s understand how and why.

Learning is about connection. A baby is born with more than 85 billion neurons in its brain, the major nerve cell of the brain. Neurons transmit information between each other through chemical and electrical signals via synapses thereby forming neural networks, a series of interconnected neurons. This is what is meant by “the wiring of the brain” and “neurons that fire together, wire together”. Neurons and synapses grow exponentially in the first years of life, even before a baby can walk and talk. Between birth and about 3 years of age, the number of synapses in the brain increases from about 2,500 to 15,000 per neuron.

As an infant experiences something or learns something for the first time, a strong neural connection is made. If this experience is repeated, the connection is reactivated and becomes strengthened. If the experience is not repeated, connections are removed. In this way, the brain “prunes” what is not necessary and consolidates the connections that are necessary. During infancy and the first years of childhood, there is significant loss of neural pathways as the brain starts to prune away what it doesn’t believe it will need to function. By the time your child reaches adulthood, the number of synaptic connections is reduced by half. Therefore, the earlier in a child’s development that we create that first, correct learning experience, the stronger those behaviors and skills are secured in the brain.

Children with developmental delays often experience the wiring of neurons together in a manner that is “unhelpful”, causing them to struggle with communication, social skills and other activities. These “unhelpful” connections need to be changed, which adds to the challenge and takes time. Technically, learning cannot be undone in the brain, but amazingly, with stimulation, the brain has the ability to re-process new pathways and build circuits that are helpful and functional. The brain has a remarkable capacity for change and adaptation, but timing is crucial. The earlier we create the correct connections in a child’s brain, the stronger those behaviors and skills are secured in the brain.

Intervention is best during early childhood when there are 50 percent more connections between neurons than exist in the adult brain. When a child reaches adolescence, another period of pruning begins where the brain starts to cut back on these important brain connections, and neurons that have not been used much. For children with all types of learning difficulties and developmental disorders, this understanding of the brain’s plasticity is particularly relevant, because it emphasizes why the correct type and intensity of early intervention is so critical. If we correctly understand a child’s skill deficits and design a program that appropriately stimulates the neurons in the targeted weakened areas of the brain, we can exercise and strengthen those areas of the brain to develop language, social skills etc.

While there is much evidence to support that early intervention is the preferred course of action because it capitalizes on this rapid early brain development, this wisdom often leaves parents or caretakers of teenage children with ASD feeling discouraged and concerned. Many children don’t have the opportunity to start therapy when they’re younger, and many others aren’t diagnosed until they’re teenagers. It may be easier and faster for children to learn new skills when they are younger, however, neuroscience tells us that the brain is still capable of learning during adolescent years, and this time period should not be forsaken.

So how do you train your child’s brain? In order to change the brain’s wiring and make new neural connections, a new skill needs to be practiced many times. Dr. Gordon recommends starting with one, simple task and practicing it at least 10 times per day. Measure how long it takes for your child’s behavior to change. This will help you determine your child’s rate of learning.

An example of a simple task is teaching your child to follow a simple instruction using a preferred item such as asking him to eat his favorite food. You can then move onto a more complex activity such as requesting eye contact by saying “Look at me” and then something more complex such as “touch the car” when playing with a toy car, for example. There are many opportunities throughout the day during normal daily parenting activities (bathing, feeding, diapering, reading, etc.) during which you can support your child’s development and train their brain to respond to people and their environment.

One common question is, “What is possible with the brain after childhood?” For many years, science has told us that brain plasticity is at its peak during childhood. However, experts now believe that under the correct circumstances, practicing a new skill can change hundreds of millions, if not billions, of connections between nerve cells in the brain even into adulthood. It is never too late to start. The most important thing to remember is that learning is what changes the brain and learning takes practice. Every opportunity to teach your child is an opportunity to shape their brain and change their future.

Top 5 Autism Studies from the Last Year

February 3, 2022 by Katherine Johnson Leave a Comment

BY KATHERINE JOHNSON, M.S., BCBA
SENIOR DIRECTOR OF PARTNERSHIPS

Looking back at 2021, there were significant developments, both in research and thought leadership, in the field of autism and applied behavior analysis (ABA).  Here are some studies and papers you don’t want to have missed!

 

Girls’ Genetics and Autism

2021 gave us another important building block in the ongoing investigation in to how and why autism manifests differently in girls than in boys.  A study by Jack et. al. found that there was a much greater difference in brain activity in autistic and non-autistic girls, than was previously found between autistic and non-autistic boys when viewing biological motion.  In the second half of the investigation, they looked at the girls’ DNA.  What they found (greater differences in brain activity and more gene mutations among the girls) bolsters the “Female Protective Effect” theory, which holds that girls require more genetic predisposition to autism in order to show autistic traits.  Inquiries into how autism manifests differently depending on sex is integral to being able to more accurately identify and support girls on the spectrum.  

Allison Jack, Catherine A W Sullivan, Elizabeth Aylward, Susan Y Bookheimer, Mirella Dapretto, Nadine Gaab, John D Van Horn, Jeffrey Eilbott, Zachary Jacokes, Carinna M Torgerson, Raphael A Bernier, Daniel H Geschwind, James C McPartland, Charles A Nelson, Sara J Webb, Kevin A Pelphrey, Abha R Gupta, the GENDAAR Consortium, A neurogenetic analysis of female autism, Brain, Volume 144, Issue 6, June 2021, Pages 1911–1926, https://doi.org/10.1093/brain/awab064

 

How Can Behavior Analysis Help Prison Reform?

Many behavior analysts have heeded the call to focus on their own cultural competence and anti-racism work; this paper outlines ways they can put those skills to good use.  Crowe and Drew review the history and current state of a social injustice faced by many people with disabilities: segregation via incarceration.  The authors posit that behavior analysts can help to interrupt the “school-to-prison pipeline” and outline their theory.  Although the authors call for a grand restructuring of the prison system (including abolition of the current system), they also offer thoughts on how behavior analysis could improve current institutions.

Bridge Over Troubled Water…

If you have been following the conversation about ABA and neurodiversity, you’ll want to read this paper.  A group of Autistic and Non-Autistic authors challenge the belief that ABA is inherently harmful for Autistic people and proposes the perspective that behavioral interventions can be “compatible with the neurodiversity paradigm.”  After a history of autism and behavioral interventions, the authors delve into a thorough discussion of how Naturalistic Developmental Behavior Interventions may bridge the gap between opposing viewpoints about the use of behavioral interventions with people on the spectrum.  

Schuck RK, Tagavi DM, Baiden KMP, Dwyer P, Williams ZJ, Osuna A, Ferguson EF, Jimenez Muñoz M, Poyser SK, Johnson JF, Vernon TW. Neurodiversity and Autism Intervention: Reconciling Perspectives Through a Naturalistic Developmental Behavioral Intervention Framework. J Autism Dev Disord. 2021 Oct 13. doi: 10.1007/s10803-021-05316-x. Epub ahead of print. PMID: 34643863.

 

The Function of…. Happiness?

And the Functional Analysis (FA) gets another twist!  Thomas et. al. assessed whether or not paying attention to indices of happiness would assist in finding effective interventions to decrease challenging behavior.  They found that when interventions were derived from what they learned about the children’s happiness, they were as effective as interventions based solely on the function of the challenging behavior, and they were associated with more behavior associated with happiness.  In the search for effective treatments that are maximally acceptable to consumers, this is a useful addition to the FA!   

Thomas BR, Charlop MH, Lim N, Gumaer C. Measuring Happiness Behavior in Functional Analyses of Challenging Behavior for Children with Autism Spectrum Disorder. Behav Modif. 2021 May;45(3):502-530. doi: 10.1177/0145445519878673. Epub 2019 Sep 30. PMID: 31565953. 

 

Assent in Research

With the addition of “assent” to the BACB Code of Ethics, behavior analysts have begun the search for research, resources, and materials on the topic.  After a discussion of the federal statute and how it may or may not apply to autistic subjects, the authors discuss assent in the context of the behavior analytic values of self-determination and choice.  They then examine how frequently assent has been obtained in the behavior analytic research (spoiler alert: not frequently), note the methods that have been used, and propose a procedure for obtaining assent from nonverbal potential research participants.  This may be the only JABA article on assent in 2021, but it’s a fair bet that it will inspire many more in 2022. 

Morris C, Detrick JJ, Peterson SM. Participant assent in behavior analytic research: Considerations for participants with autism and developmental disabilities. J Appl Behav Anal. 2021 Sep;54(4):1300-1316. doi: 10.1002/jaba.859. Epub 2021 Jun 18. PMID: 34144631.

Autism Today: A Look at How Far We Have Come and What is Still Needed

August 6, 2021 by Priorities Leave a Comment

Dr. Fred Volkmar, a professor at Yale University with over 40 years in the field of autism-related studies, joins us to provide perspective on how far we have come in the diagnosis, research, and services for individuals with autism.  With all the gains, there is still a great need for more research.  As Dr. Volkmar put it, “I think until we get more parents pushing for work on adults, we’re just not going to see it. You have to put your money where your mouth is and I think the federal government needs to fund more research on adults with autism”. Dr. Volkmar also discusses his latest book written with his wife, Dorothy Goodwin which aims to provide parents with practical help for their family.
