Questions & Answers about Датчик фиксирует высокую активность мозга.
Why does the adjective высокую end in -ую while the noun активность doesn't change its ending?
Активность is a feminine noun ending in a soft sign (-ь), meaning it belongs to the 3rd declension. For these nouns, the Accusative case looks exactly the same as the Nominative. However, the modifying adjective высокую still must take the standard feminine Accusative ending -ую.
Does фиксирует mean fixes as in repairing something?
No, this is a common false friend. While фиксировать can mean to physically secure something in place, in scientific or technical contexts it means to record, register, or log data. If you want to talk about repairing a broken device, you would use чинить or ремонтировать.
Why is мозга in the Genitive case here?
It expresses the idea of the activity of the brain. In Russian, when you have a noun modifying another noun like this (often combined into a single compound phrase in English, like brain activity), the second noun goes into the Genitive case.
Where does the word датчик (sensor) come from?
It is derived from the verb дать (to give). In technical and engineering contexts, a датчик is a device that gives or transmits data to a system, which logically describes a sensor or detector.
