What did Ben Barres discover?
Barres was best known for his work on glial cells, and he describes his lab’s major scientific contributions, including his surprising discovery that these cells release factors that help make synaptic connections between neurons.

Where did Ben Barres work?
Stanford
Arriving at Stanford In 2008, he became chair of neurobiology. From 2005 on, he was the director of the Masters of Science in Medicine Degree Program for PhD students, which he had created. At Stanford, Barres turned his attention to a second class of glial cells known as astrocytes.
What do we know about glial cells thanks to Ben Barres?
Barres sought to understand the normal functions of glial cells in order to understand what happened when things went awry. Among other things, the glia appeared to help neurons form synapse connections to transmit electrical signals throughout the brain.
What type of cells are astrocytes?
Astrocytes are a sub-type of glial cells in the central nervous system. They are also known as astrocytic glial cells. Star-shaped, their many processes envelop synapses made by neurons.
How do glial cells work?
Each type of glial cell performs specific jobs that keep the brain from functioning. Primarily, glial cells provide support and protection to the neurons (nerve cells), maintain homeostasis, cleaning up debris, and forming myelin. They essentially work to care for the neurons and the environment they are in.
What do astrocytes cells do?
Astrocytes are the most numerous cell type within the central nervous system (CNS) and perform a variety of tasks, from axon guidance and synaptic support, to the control of the blood brain barrier and blood flow. This suggests that glial cells represent potential therapeutic targets in MND.
What do astrocytes do in CNS?
Astrocytes are the most numerous cell type within the central nervous system (CNS) and perform a variety of tasks, from axon guidance and synaptic support, to the control of the blood brain barrier and blood flow.
Do astrocytes produce myelin?
Astrocytes Provide Lipids for Myelin Sheath Production Still consistent with their implication in myelination, astrocytes were also proposed to supply lactate to oligodendrocytes. Lactate constitutes a source of energy and a precursor of lipid synthesis including cholesterol altogether necessary for myelin production.
What is the purpose of dendrites?
The Dendrites Dendrites are appendages that are designed to receive communications from other cells. They resemble a tree-like structure, forming projections that become stimulated by other neurons and conduct the electrochemical charge to the cell body (or, more rarely, directly to the axons).
