Sensory Implications of Brain Organoids with Patricia Churchland
11/8/2019
What defines consciousness? Can it develop in a petri dish? Patricia Churchland reviews the current state of brain organoid research and shares her views on how conciseness and physical structures within the brain intersect. She also cautions the media on the tendency to "over hype" new research advances. Recorded on 10/04/2019.
Neural Organoids Are Not Brains in Vats with Evan Thompson
11/8/2019
Recently, some scientists have asked whether neural organoids will ever be conscious, and have wondered about the ethical implications of this possibility. Meanwhile, some philosophers have argued that neural organoids are miniature versions of "brains in vats." Evan Thompson feels that both scientist and philosophers should shift their thinking. He argues that the minimal instantiation of sentience is organismic - not just neuronal, and that conscious processes of...
Consciousness in Cerebral Organoids - How Would We Know? with Christof Koch
11/2/2019
As brain organoids become more widely used in research, concerns about the development of consciousness arise. Christof Koch discusses how we determine and define consciousness and how we look for the underlying physical signatures of consciousness. Recorded on 10/04/2019.
The Current Status of Human Brain Organoids Research with Alysson Muotri and Larry Goldstein
11/1/2019
The study of brain organoids is leading to a better understanding of human development and potential therapies for neurological disorders. Yet when people hear the phrase "brain in a dish" it instantly brings to mind the stuff of science fiction - labs full of sentient brains thinking and plotting. Alysson Muotri explains why these organoids should not called "brains in a dish" and how they are being used to explain human processes previously inaccessible to...
Stem Cells to the Rescue: Saving the Northern White Rhino from Extinction
10/29/2019
There are only two Northern White Rhinos left on the planet. How can we reverse extinction to save them and use the lessons learned to help other endangered species? Marisa L. Korody, PhD of the San Diego Zoo Institute for Conservation Research shares how scientists are using the latest in stem cell technology for a genetic rescue.
How to Make a Neuron and How Pioneer Factors May Find Their Targets
10/7/2019
Marius Wernig, MD, PhD, discusses how his lab has worked to convert non-neuronal cell types (lymphocytes, pluripotent stem cells, fibroblasts, hepatocytes, lymphocytes) to neurons. The lab is now working on identifying the molecular mechanisms underlying induced lineage fate changes, the phenotypic consequences of disease-causing mutations in human neurons and other neural lineages.
Making Pluripotent Stem Cells
9/13/2019
With the capacity to form any tissue in the human body, induced pluripotent stem cells, or iPSCs, are critical to the work of the UC San Diego Stem Cell program in studying disease and potential cures - but how are they made? This short primer outlines the basic steps to how these special cells are derived.
Beginnings in the Brain: Complex Oscillatory Waves Emerging from Cortical Organoids Model Early Human Brain Network Development
8/28/2019
A detailed overview of a study conducted by Alysson Muotri's lab at the UC San Diego Stem Cell Program which found complex network signaling developing in human cortical organoids that appear to recapitulate fetal brain development, offering an in-vitro model to study functional development of human neuronal networks.
Making Brain Organoids: A Primer
7/31/2019
Brain organoids, or cortical organoids, hold much promise in finding interventions for neurological conditions, and have already proven useful in understanding the effects of Zika and rare neurological syndromes such as AGS. But how are they made? UC San Diego Stem Cell program project scientist Cleber Trujillo provides a brief overview of how the Muotri lab nurtures pluripotent stem cells into becoming brain organoids.
3D Printing with Stem Cells - Shaochen Chen
7/29/2019
