Hi there. The "electrical brain" is the ECU or ECM. However, it is common that other ignition system components like a crankshaft or cam position senor is causing the hard to start issue you are experiencing. Before you take the car to Nissan for car brain surgery, you might want to have a professional mobile mechanic come to your location and complete a car is hard to start inspection first.
