Autism Spectrum Disorder is a developmental disorder that impairs communication, behavior and the way an individual perceives the world. Researchers worldwide are constantly trying to research the brain to get to know the causes of autism as well as learn more effective methods of helping such individuals. Neuroscience has made new discoveries that are assisting researchers to learn how various sections of the brain affect behavior and sense perception.

In recent times, scientists in Stanford Medicine have discovered a significant finding that could aid in enhancing our knowledge on autism. Their study revealed that the behavior of autism in mice could be corrected by soothing a minor yet significant section of the brain. Despite the fact that this research is not around and thus is still in its infancy, there is a future that scientific research can look forward to.

Researchers targeted a section of the brain referred to as the reticular thalamic nucleus in the study. This section of the brain acts as a gatekeeper in that it governs the flow of sensory input to other parts of the brain as sounds, touch and sight. Under proper functioning of this system, the brain is able to filter and react towards the environment in the most appropriate manner.

The brain however can be inefficient in filtering the sensory signals in some individuals with autism. This may result in sensory overload. As an example, loud noises, bright lights or certain textures can be highly uncomfortable or overwhelming. Due to this fact, there are those people with autism who respond intensively to normal sensory experiences.

To further explain how this process works, researchers have performed experiments on mice, which were genetically engineered to behave like those who were affected by autism. Such mice had repetitive behaviors, decreased socialization and abnormal response to sensory stimuli.

The researchers found out that there was an excess activity in the reticular thalamic nucleus in such mice. This over activity interfered with communication among various regions of the brain, which added up to autism like behaviors.

The scientists tried two methods in order to rectify the problem.

The former technique was the application of a drug, which is widely applied in the treatment of epilepsy or a seizure. This medication assisted in lowering the hyperactivity of the brain.

The second one was the neuromodulation. Neuromodulation is the method, which alters the activity of the brain in terms of electrical or chemical stimulation. It assists in repairing the overactive and underactive brain circuits.

The researchers noted promising outcomes after treatment with these interventions. The activity in the brains of the mice was more balanced, and the behavior of the mice changed greatly. The mice also got more relaxed, social and less sensitive to sensory input. Their actions started to act as normal mice.

The other notable finding of this study was the close relationship that exists between epilepsy and autism. Researchers discovered that the two conditions possibly share common brain circuits that regulate the movement of signals in the brain. This observation can be relevant as a number of patients with autism have epilepsy. The understanding of the similar mechanisms of the brain can assist scientists in making treatments that could be of use to the two conditions.

The study is important in that it presents a new method of comprehending autism. Most of the treatment is traditionally aimed at the management of such symptoms as speech delay, behavioral difficulties, or social problems. Nevertheless, this study implies that treatment in the future would be aimed at dealing with these brain circuits that promote such behaviors.

Scientists can possibly develop more effective treatment methods by attacking the underlying brain activity. Future treatment can assist in enhancing the brain mechanisms that cause autism, as opposed to merely assisting people to cope with the symptoms.

Nevertheless, one should realize that this research was done on mice and not on human beings. Animal studies are usually the initial step towards scientific discoveries as they are used to get an insight into the mechanisms of biological systems. It will take several years of research, testing and clinical trials before similar treatments can be administered to humans.

Irrespective of these weaknesses, the results are useful in understanding the mechanisms of brain functioning in autism. They also promote the new research directions among scientists and the creation of new treatments.

Simply, this finding indicates that it is possible to treat some hyperactive brain circuits to enhance behaviors related to autism. Today, although it is not a remedy, it provides new opportunities in future research and gives some hope to families, educators, and healthcare workers who assist persons with autism.
