Neural Noise Role in Understanding Autism Spectrum is Finally Revealed!

United States: Autism is a neurodevelopmental disorder that is characterized by features that are unique to the condition.

Autism studies have mostly centered on behavioral, cognitive, social, and communication deficits for a long time. These researches revealed the fact that autistic people face challenges with all the things that allistic (meaning non-autistic)) people do not. Some cases include misunderstanding emotions and social signals, which can be quite challenging.

The sound never stops, and on its revision, all other brain activity that comes with what we see, hear, smell, and touch is also preserved. In the brain, this happens when the same stimulus is presented several times, as they will not lead to equally identical neuronal activity.

Brain activity is not constant but fluctuates up and down. Actually, a person will behave this way or that way as a consequence of the reaction to that single stimulus or activity, as reported.

The brain is the place where there are many sources of neural noise. They involve the neurons being both stimulated and returned into peace, alteration in the attention and arousal levels, and cellular level biochemical processes, among many others.

The human allistic brain is designing and using a mechanism for this background noise. Simply speaking, cells in the hippocampus (the brain’s memory system) may use neural noise as a tool for encoding and recalling memories, which is very effective.

One of the ways to show that high neural noise exists in autism is to conduct electroencephalography (EEG) studies, where this abnormal condition of increased levels of neural fluctuations is observed in children with autism.

Since their neural activity is less foreseeable and shows wider variation, they exhibit a more volatile state of activity pattern in response to the same given stimuli.

To put it simply, suppose that the EEG responses are like a sound wave. Then, there must be small ups and downs in the brain responses (amplitude) of the allistic brain for each stimulus. Yet, autistic brains are found to fill the gaps between the neurons more, with neural ocean showing more intensive movement, as reported.

Is there any usefulness of Noise?

The detection of autism goes back to the practice of medicine very long ago. This development where the medical becomes more of a social model has as well resulted from some advocacy asking for it to be reframed as difference instead of disorder or deficit.

Such transformation has also been agreed upon the autism research. Research can analyze system as well as the myriad of abilities that a neurodiverse perspective can bring.

Psychologist and perception researcher David Simmons’ and the University of Glasgow group were the first suggests that high noise signal is a mostly disadvantageous phenomenon in autism and has no positive consequences; however, it can sometimes provide the advantages because of a characteristic called stochastic resonance.

It is where performance can only be medium. According to this theory, the autistic neural noise could correspond with an enhancement in some of the cognitive tasks, perhaps even causing a slight increase in the performance level.

Our 2023 research project will dive into this concept. By enrolling participants from the public and carrying out the letter-identification trials, we have been able to gain an understanding of these cognition processes of the human brain functioning. On the one hand, we estimated these individuals’ levels for autistic traits.
