BARseq builds a better brain map
October 17, 2019
A brain mapping technique called BARseq is capable of mapping thousands of neurons in a single mouse, at single neuron resolution, while also detailing which neuron expresses what genes. It could be a game-changer for how neuroscientists look at brains....

Sweat monitors predict behavioral issues in teens severely affected with autism
October 10, 2019
When people become stressed, their bodies can respond by sweating. Now, researchers are monitoring how much adolescents severely affected by autism sweat in order to better understand when behavioral issues, such as aggression, are likely to occur.
Severe morning sickness associated with higher risk of autism
October 3, 2019
Children whose mothers had hyperemesis gravidarum -- a severe form of a morning sickness -- during pregnancy were 53% more likely to be diagnosed with autism spectrum disorder, according to new research.
Exploring the brain in a new way: Researcher records neurons to understand cognition
October 1, 2019
Whether we're searching for Waldo or our keys in a room of clutter, we tap into a part of the frontal region of the brain when performing visual, goal-related tasks. Some of us do it well, whereas for others it's a bit challenging. One researcher set out to investigate why, and what specifically thi...

New evidence challenges 'extreme male brain' theory of autism
September 5, 2019
A new study has challenged suggestions that the male sex hormone testosterone reduces cognitive empathy, or the ability to read other people's emotional states. Lower cognitive empathy is a feature of autism, a condition that predominantly affects males....

New study shows how autism can be measured through a non-verbal marker
August 15, 2019
A Dartmouth-led research team has identified a non-verbal, neural marker of autism. This marker shows that individuals with autism are slower to dampen neural activity in response to visual signals in the brain. This first-of-its kind marker was found to be independent of intelligence and offers ...

Brain protein mutation from child with autism causes autism-like behavioral change in mice
July 23, 2019
A de novo gene mutation that encodes a brain protein in a child with autism has been placed into the brains of mice. These mice then showed severe alterations of specific behaviors that closely resemble those seen in human autism spectrum disorder, or ASD.
This major finding from a st...

Researchers devise a more 'child-friendly' test for autism
July 11, 2019
The current methods of diagnosing autism in children use questionnaires and psychologist evaluations. However, these methods can be stressful for those at a young age. New research now suggests an easy, more stress-free test that simply tracks the gaze....

Unusual eating behaviors may be a new diagnostic indicator for autism
July 9, 2019
Atypical eating behaviors may be a sign a child should be screened for autism, according to a new study from Penn State College of Medicine.
Research by Susan Mayes, professor of psychiatry, found that atypical eating behaviors were present in 70% of children with autism, which is 15 ...

How a unique gene mutation may drive autism
July 4, 2019
Which factors drive autism? This is a question to which researchers still have no answer. Now, a new study conducted in mice and assessing data from humans suggests that a unique genetic mutation may play a key role in early brain development, contributing to autism....
