Studying neural correlates of consciousness has many problems. Which statement does NOT reflect these issues:

A) It is hard to disentagle which neural activity is associated with conscious awareness and task-related processes
B) Neuroimaging measures may access consciousness more directly than behavioural measures alone
C) It is hard to establish the relationship between a given pattern of neural activity and consciousness
D) Research is limited to neural correlates of visual conscious awareness
E) Little is known about neural processess associated with conscious awareness of past or future events
