|Does body mass and size influence the time before irreversible brain damage?|
|I heard that first-born males are more likely in younger couples who have sex frequently, because male sperm are more likely to reach the egg just after ovulation. Is there any truth to this, and if so, how is sex ratio maintained?|
|How are data, like found on computers, carried and stored? Does our own memory work in the same way?|
|Are any biomaterials that mimic skin used for testing drugs or cosmetics?|
|Can you listen to an iPod using ear buds in a vacuum?
Since there’s no air in space, there can be no sound waves. My student would like to propose an imaginary scenario: He is floating in space (ignoring that there’s no oxygen and subzero temp) with his iPod in. Can he hear it? I said no, because you’d still need air between the earbud and his eardrum for the sound waves to travel, but we’d like to hear it from a scientist.
|Are the blood brain barrier and the availability of glucose the ONLY reasons the brain uses glucose almost exclusively?|
|There are certain kinds of food that I like and some that I dislike, just like everybody else. But from an evolutionary standpoint, it seems like we shouldn't be turning our noses up at anything that helps us survive, nor should we have differing tastes than other people living in the same environment. Why would we develop a distaste for certain foods?|
|For how long do macrophages dock with helper T cells?|
|I've read that the (whole) brain consumes 20% of the total body energy expenditure at rest. How much energy do the the different areas of the brain consume for various tasks such as higher executive functioning More specifically, how can I find out about the varying metabolic requirements of different executive functions (goal related behavior) such as response inhibition, prioritizing, reasoning and scenario planning (etc) vs. lower level (limbic) tasks? Thanks.|
|I am watching the fascinating HHMI 2008 Holiday Lecture " Making Your Mind". Our experiences have components of our various senses. If each sensory component is a neural circuit, would there be some form of indexing to link the various circuits? Could you recommend an introductory book/article on the subject?|
