Atmospheric sciences and radiant energy. In contrast to meteorology, which studies short term weather systems lasting up to a few weeks, climatology studies the frequency and trends of those systems. It studies the periodicity of weather events over years to millennia, as well as changes in long-term average weather patterns, in relation to atmospheric conditions. Climatologists, those who practice climatology, study both the nature of climates – local, regional or global – and the natural or human-induced factors that cause climates to change. Climatology considers the past and can help predict future climate change. Phenomena of climatological interest include the atmospheric boundary
Long-term depression striatal neurons leads to a long term decrease in inhibitory effects on the basal ganglia, influencing the storage of motor skills. Long-term depression has also been observed in the visual cortex, and it is proposed to be involved in ocular dominance. Recurring low-frequency stimulation of layer IV of the visual cortex or the white matter of the visual cortex causes LTD in layer III. In this form of LTD, low-frequency stimulation of one pathway results in LTD only for that input, making it homosynaptic. This type of LTD is similar to that found in the hippocampus, because it is triggered
