Why We’ve Been Ignoring These Brain Cells | Great Minds: Ben Barres

The video explores the roles of neurons and glial cells in the brain, highlighting the historical bias towards neurons. It delves into the functions of different glial cells, such as oligodendrocytes, microglia, and astrocytes, emphasizing their importance in brain function. The work of neurobiologist Ben Barris is discussed, particularly his discoveries about astrocytes and their role in synapse formation. The video also touches on Barris's advocacy for gender equality in science, drawing from his experiences as a transgender scientist.

What was the initial belief about the role of glial cells in the brain?

• They were believed to regulate blood flow in the brain.

• They were considered the main communicators in the brain.

• They were thought to be responsible for memory storage.

• They were seen as mere support structures for neurons.

Which type of glial cell is responsible for forming the myelin sheath?

• Oligodendrocytes

• Neurons

• Microglia

• Astrocytes

What critical role do astrocytes play in the brain?

• They store memories.

• They form and maintain synapses.

• They produce hormones.

• They send electrical signals.

How did Ben Barris contribute to the understanding of glial cells?

• He showed they regulate blood flow.

• He proved they are responsible for memory storage.

• He identified their involvement in synapse formation.

• He discovered their role in electrical signaling.

What was one of Ben Barris's significant contributions to the scientific community beyond his research?

• He developed a new type of neuron.

• He invented a medical device.

• He advocated for gender equality in science.

• He discovered a new planet.
