Does storing objects in a std::vector increase the lifetime of the object ?

for (int i = 0; i < 10; i++)
    { 
        nueron temp; // my Class
        _inputNuerons.push_back(temp); // _inputNuerons is a std::vector 
    }

From what I know , C++ deallocates the temp object when it reaches the } bracket of the for loop. But does storing the object in a std::vector make the object usable later on in the program ? Now when I try to access the "temp" nueron outside the for loop , the program crashes.

How can I store my objects in a std::vector such that it is usable later on ?
