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 large neural networks so that these regions can be further studied using more traditional electrophysiological recording devices. Single-unit recording directly measures action potentials and can be used in a variety of animals. This technique employed in the macaque monkey led to the discovery of the mirror neuron which has major implications for learning, memory and the perception of self. Single cell recordings can be used to record the activity of single neurons while animals perform tasks related to memory. Cortical cooling is a relatively new technique that allows for a temporary disruption of function in a chosen area of the
