Autism Research

Autism Research lectures bring together scientists and scholars to discuss diverse and important topics related to autism.

Video replay of this event will be available shortly. Please check back at a later date.

On 1 November 2017, Paola Arlotta focused on the cerebral cortex and presented the challenges and opportunities of modeling human brain development using pluripotent stem cells within 3D human brain organoids. Building on developmental work in mice, such organoids promise a better understanding of complex neurodevelopmental conditions such as autism spectrum disorder.

Her talk was part of the Simons Foundation Autism Research lecture series.

About the Lecture

The cellular and molecular processes that control brain development in mammals, as well as how neurodevelopmental disorders affect such processes, remain poorly understood. The recent advent of brain organoids (lab-grown clusters of living neurons) offers new ways to study the relationships between neurodevelopmental disorders and brain development.

In this lecture, Paola Arlotta focused on the cerebral cortex and presented the challenges and opportunities of modeling human brain development using pluripotent stem cells within 3D human brain organoids. Building on developmental work in mice, such organoids promise a better understanding of complex neurodevelopmental conditions such as autism spectrum disorder. She discussed her recent work on the generation and long-term development of human brain organoids and the study of their developmental trajectories, cellular diversities and neuronal network features.

Arlotta then showed that phenotypic abnormalities observed in patients carrying genetic mutations linked to autism spectrum disorder can be reproduced within brain organoids. This work serves as a proof-of-principle demonstration that selected aspects of human neurodevelopmental conditions can be modeled in vitro with the goal of better understanding disease genetics and pathology.

About the Speaker

Paola Arlotta is a professor of stem cell and regenerative biology at Harvard University. She is a principal faculty member at the Harvard Stem Cell Institute, where she is co-director of the neuroscience program, an institute member at the Broad Institute, and an associate member of the Stanley Center for Psychiatric Research at the Broad Institute. She is interested in understanding the molecular laws that govern the birth, differentiation and assembly of the human brain’s cerebral cortex. The complexity of the brain fascinates her and she is driven to integrate developmental and evolutionary knowledge to investigate therapies for brain repair and for modeling neuropsychiatric disease. Arlotta received her M.S. in biochemistry from the University of Trieste, Italy, and her Ph.D. in molecular biology from the University of Portsmouth in the UK. She subsequently completed her postdoctoral training in neuroscience at Harvard Medical School.

Past Lectures

Rare variants and the genetics of autism

Evan E. Eichler, Ph.D.Professor, Department of Genome Sciences and Howard Hughes Medical Institute, University of Washington, Seattle

Evan Eichler discussed his research on the genetics of autism and related neurodevelopmental conditions.

Phenotyping sleep

Emmanuel Mignot, M.D., Ph.D.Craig Reynolds Professor of Sleep Medicine, Stanford University

Emmanuel Mignot discussed sleep biology as well as sleep disorders and their impact. He presented a link to what is known on the genetics of sleep and sleep disorders. He emphasized the need for large scale objective sleep recording studies with genomic and proteomic analysis to better understand the molecular pathways regulating sleep and circadian biology.
