Professor Diamond continues her discussion of the nervous system and begins by revisiting her discussion of the ascending path. She notes the presence of substantia gelatinosa in the area of the second neuron and describes the concept of homunculus, which is the upside-down representation of the body in the brain, and notes that this does not occur in the face for reasons unknown to neurologists. Professor Diamond then begins describing th...more

A perennial favorite is the idea of time travel. What would happen if we could go back in time and alter the future a la “Back to the Future”? The great narrative of the history of life has a complexity rife with subplots and twists, many of which we will never uncover. Yet somehow the story of life on Earth began with a prebiotic ooze and ended with the awe-inspiring diversity of life we see today – including us. But like any story, th...more

Professor Diamond continues her discussion of the nervous system beginning with a discussion of myelin-forming oligodendrocytes and Schwann cells, saltatory conduction from the nodes of ranvier, and the similarity of the function of microglia to monocytes. She moves on to describe the development of the neural tube by drawing a cross-section of the neural tube and depicting the changes it undergoes, forming the ventricles of the brain, whi...more

In this lecture, Professor Diamond continues her discussion of hematology by describing the two major blood cell types, erythrocytes and leukocytes. She begins by reviewing erythrocytes (red blood corpuscles or RBCs) and their characteristics. She discusses differences between RBC counts in men and women and factors like exercise that impact RBC counts. She then contrasts the properties of erythrocytes with those of leukocytes, noting t...more

If the extent of French collaboration during World War II has been obscured, so too has the nature of resistance. Although the communist Left represented the core of the resistance movement, resistors came from any different backgrounds, including in their ranks Catholics, Protestants, Jews and socialists. Unlike the relationship between de-Christianization and right-wing politics, in the case of the resistance there is no clear correlatio...more

Stefan Heller is trying to create inexpensive ear drops that can cure deafness. In this short talk, Heller describes how his team of researchers at Stanford University is transplanting stem cells into the ear to "regenerate" damaged hearing cells.

In this lecture, Professor Diamond begins with a review of the respiratory bronchile. She then continues to discuss the structure of the lungs including the trachea, hilum, primary bronchi, pulmonary arteries and veins, nerves, alveoli and diaphragm, as well as the parietal pleura and the visceral pleura. After building this foundation she describes the process of innervation and the firing of the phrenic nerve before moving into an intr...more

This course explores the basic principles of chemistry and their application to engineering systems. It deals with the relationship between electronic structure, chemical bonding, and atomic order. It also investigates the characterization of atomic arrangements in crystalline and amorphous solids: metals, ceramics, semiconductors, and polymers (including proteins). Topics covered include organic chemistry, solution chemistry, acid-base eq...more

In this lecture, Professor Diamond continues her discussion of the nervous system and begins by reviewing the telencephalon before transitioning into a discussion of the six layers of the neocortex. She discusses the hippocampal-dentate complex, the archicortex, and the temporal lobe, which contains the hippocampus and pyramidal cells along with the fimbrea, fornix, and mammilary bodies. To enhance students' understanding of the neural tu...more
