In brain decoding encoding methods we are dealing with features at the stimuli side (image, videos, etc.) these features includes shape, color, texture etc. In the brain activity side we have for example fMRI time series data related to the some stimuli, and we extract features from this signals. The question is can we map between two types of aforementioned features?
You could refer to the following two seminal papers that propose a method in attempted to map the two different spaces (perceptual vs stimulus):
Kriegeskorte N, Mur M, Bandettini P (2008), “Representational similarity analysis - connecting the branches of systems neuroscience.” Front Syst Neurosci 2:4
Kriegeskorte N, Mur M, Ruff DA, Kiani R, Bodurka J, Esteky H, Tanaka K, Bandettini PA (2008), “Matching categorical object representations in inferior temporal cortex of man and monkey.” Neuron 60(6):1126-41
And in the lab of Jack Gallant they've done a lot to build forward models to predict individual's percept from moltivoxel fMRI BOLD signal:
