Neurogenesis in the mammalian brain
The human brain contains ~86 billion neurons and an equal number of glial cells. The majority of these cells are generated between 5 weeks and 8 months of prenatal development. This video walks through the process of neural stem cells and neural proliferation.

Central Taste Pathways
Переглядів 1,1 тис.3 роки тому
A look at the pathways that carry gustatory information into the brain. We look at the key brain structures, their functions, and finish by looking at modulation of the pathways using input from other sensory modalities as well as based on experience.
Insulin PI3K Akt signaling pathway
Переглядів 4,4 тис.3 роки тому
The video begins with an overview of the role of insulin in regulating blood sugar levels. Then it reviews the structure and activation of the insulin receptor, and the IRS-PI3K-Akt pathway. It shows how Akt can lead to insertion of GLUT4 vesicles into membranes, and then looks at the metabolic actions in liver and fat cells.

GPCR AC cAMP PKA pathway
Переглядів 10 тис.4 роки тому
This video walks through the GPCR, G alpha s, adenylate cyclase signaling pathway. It examines the cellular events for each step. The video concludes with a look at how the pathway is inactivated and the role of arrestins in cell signaling.
GPCR IP3 DAG pathway
Переглядів 7 тис.4 роки тому
A walk-through the g protein coupled IP3 DAG pathway. This is one of the common GPCR linked signaling pathways, and the video illustrates each of the players: how GPCRs activate Galpha subunits; how Galpha activates phospholipase C (PLC), how IP3 and DAG are produced, and their targets in the cell. Video includes two examples of this pathway is specific cell types degranulation of mast cells an...
