Average activity, but not variability, is the dominant factor in the representation of object categories in the brain

Highlights • Within-trial variability of neural activities provide information regarding object categories. • The mean of activities plays a significant role in category encoding in the brain. • The independent variability, although effective, contribute only moderately to the category representatio...

Description
Summary:Highlights • Within-trial variability of neural activities provide information regarding object categories. • The mean of activities plays a significant role in category encoding in the brain. • The independent variability, although effective, contribute only moderately to the category representation. • The correlated variability between the EEG channels has an ignorable effect on the representations.
