Weather front areas of precipitation help determine the frontal type and location. There are two different meanings used within meteorology to describe weather around a frontal zone. The term "anafront" describes boundaries which show instability, meaning air rises rapidly along and over the boundary to cause significant weather changes. A "katafront" is weaker, bringing smaller changes in temperature and moisture, as well as limited rainfall. A cold front is located at the leading edge of the temperature drop off, which in an isotherm analysis shows up as the leading edge of the isotherm gradient, and it normally lies within a sharp surface
Methods used to study memory can be selected for memory and learning ability, maybe we can learn something about how genes contribute to memory systems. Functional magnetic resonance imaging (fMRI) has intriguing implications for the study of memory in humans, however it can also be used in animal models. fMRI can be used to assess brain functionality in monkeys in the context of a variety of behavioral tasks. Structural MRI can be used to examine the extent and location of brain lesions, so that behavioral abnormalities observed can be directly linked to specific brain structures. High-resolution fMRI can help locate and assess the functionality of
