The analytical consideration of some recent experimental and theoretical data on the hydrogen on-board storage problem shows the necessity and economical expediency of carrying out further basic studies and initiating a constructive discussion on the physical key-note aspects ("open...

Spatial and temporal features of superordinate semantic processing studied with fMRI and EEG.

Frontiers in human neuroscience

Costanzo ME, McArdle JJ, Swett B, Nechaev V, Kemeny S, Xu J, Braun AR.

Front Hum Neurosci. 2013 Jul 01;7:293. doi: 10.3389/fnhum.2013.00293. eCollection 2013.

The relationships between the anatomical representation of semantic knowledge in the human brain and the timing of neurophysiological mechanisms involved in manipulating such information remain unclear. This is the case for superordinate semantic categorization-the extraction of general features shared...
