What is correct about the default and the salience networks of brain activity?

		Although both networks show increased activity when the subject is performing a task, the default network is defined by fMRI and the salience network is defined by ERP (evoked responses measured by EEG).
		When the subject is performing a task, there is decreased activity in the default network and increased activity in the salience network.
		When the subject is performing a task, there is decreased activity in both networks.
		The default network is activated with eyes closed and during slow wave sleep, whereas the salience network is activated with eyes open or during REM sleep.
