The invention provides a brain function network construction method. The brain function network construction method comprises the steps that EEG signal mutual information between EEG channels of each EEG signal subset in an EEG signal set is obtained to obtain an EEG signal mutual information set of each EEG signal subset, and the EEG signal set comprises more than two EEG signal subsets; based on the EEG signal mutual information set of each EEG signal subset, a mutual information adjacent matrix of each EEG signal subset is generated; based on the mutual information adjacency matrix of each EEG signal subset, a connection state set between electroencephalogram channels of the EEG signal subset is obtained; and a brain function network is correspondingly constructed based on the connection state set of each EEG signal subset. The invention further provides a brain function network construction device, electronic equipment and a readable storage medium.
