and decreases in the motor and somatosensory cortex, temporal lobe including left amygdala, cingulate cortex, insula and thalamus. (researchgate.net)

New research has found that this area of the brain grows too rapidly in the first year of life in babies who go on to develop autism. (aau.edu)
The amygdala is a small structure deep in the brain important for interpreting the social and emotional meaning of sensory input - from recognizing emotion in faces to interpreting fearful images that inform us about potential dangers in our surroundings. (aau.edu)
We are getting closer to understanding why autism occurs by learning more about brain growth alterations early during development, in this case how amygdala growth may be influenced by early sensory processing difficulties and, conversely, how amygdala growth alterations may influence a baby's interaction with their environment," said Dr. Stephen Dager , professor of radiology in the UW School of Medicine and an adjunct professor of bioengineering. (aau.edu)
In 2019, the multicenter research team received a five-year, $9.5 million grant from the National Institute of Mental Health to continue their efforts to determine whether brain imaging can help detect infants who are likely to go on to develop autism spectrum disorder. (aau.edu)
How this process occurs is not fully understood, but new research shows how specific molecules in separate parts of the brain gather and transmit threat cues to the amygdala, which transforms them into fear. (medicalnewstoday.com)
A 2016 research review discusses that this fear response is processed in a brain region called the amygdala. (medicalnewstoday.com)

The amygdala comprises two almond-sized-and-shaped portions of the mid-brain, that are becoming more and more common targets for study. (typepad.com)
And while there are two units (left and right sides of the brain) to the amygdala, it is more often discussed as if it were one organ, so the singular term "amygdala", and the common usage plural "amygdalas," not the Latin plural "amygdalae" is used here and throughout most of the medical literature. (typepad.com)
But the amygdale is not a part of the conscious brain. (typepad.com)
The study of the function of the amygdale has helped resolve one of the great debates in neuroscience over the last 250 years: Whether the Body (in this case, the amygdala and the brain) governed the Mind (in this case, the sense of consciousness, self-awareness, thought processing, learning and memory), or whether these were two truly distinct operations. (typepad.com)
The amygdala may very well do this by helping the brain identify salient points of new inputs (whether they have red or green flags indicating either danger or reward) and to prioritize them by the use of the "magnitude dial" of the amygdale (important enough to pay close attention, or not so important or threatening and therefore, something to ignore).
