7.343 Neuron-glial Cell Interactions in Biology and Disease (MIT)
The main goal of this seminar will be to study the nervous system from the perspective of neuron-glia interactions. In each class, we will focus on one type of glial cell and discuss its origin, classification and function within the nervous system. Current findings concerning diseases associated with each type of glial cell will be discussed. This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an inte

6.2 Number of neurons hypothesis

In addition to an increase in firing rate of neurons with differing dynamic ranges, the inclusion of discharges from many fibres whose CFs are different from those of the stimulus may also help to account for the wide dynamic range of the ear. You know from Section 3.3 that in response to a pure tone stimulus the basilar membrane vibrates maximally at a

1 Overview

Even in images taken with the most modern equipment on a large telescope, it can be difficult to pick out the galaxies now known as 'active' from the other more normal galaxies. But if your telescope were equipped to examine the spectra of the galaxies, then the active galaxies would stand out. Normal galaxies contain stars that are generally similar to those in our own Galaxy; and spiral galaxies have additional similarities to the Milky Way in their gas and dust content. Active galax

1.3.4 Hormonal control of sperm production

The most important hormone involved in controlling sperm production is a steroid called testosterone. This is produced in the testis itself, by the Leydig cells (see Figure 12a). The testosterone is released from the Leydig cells between the tubules, and taken up by the neighbouring Sertoli cells. The Leydig cells are stimulated to make testosterone by two other hormones, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which are both produced by the pituitary gland and

Many Planets, One Earth
Note: This link leads you to several videos about our solar system. The early Earth was a much different planet than the one we know today. Ancient rocks provide evidence of the emergence of oxygen in the atmosphere and of a frozen Snowball Earth. Scientists Paul Hoffman and Andrew Knoll look at these clues to help explain the rise of complex animal life.
