Atmospheric sciences Atmospheric sciences Atmospheric sciences are the study of the Earth's atmosphere, its processes, the effects other systems have on the atmosphere, and the effects of the atmosphere on these other systems. Meteorology includes atmospheric chemistry and atmospheric physics with a major focus on weather forecasting. Climatology is the study of atmospheric changes (both long and short-term) that define average climates and their change over time, due to both natural and anthropogenic climate variability. Aeronomy is the study of the upper layers of the atmosphere, where dissociation and ionization are important. Atmospheric science has been extended to the field of planetary
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
