ISO is the sensitivity of your sensor to light. The ISO setting you use depends on the amount of light in the scene you are photographing. The more light you have to work with the lower you can set your ISO.
Each side of your brain contains four lobes. The frontal lobe is important for cognitive functions and decision-making. The parietal lobe processes information about temperature, taste, touch and movement, and spatial orientation. The occipital lobe is primarily responsible for vision.
The temporal lobe is responsible for phonological awareness and decoding/discriminating sounds. The frontal lobe handles speech production, reading fluency, grammatical usage, and comprehension, making it possible to understand simple and complex grammar in our native language.
