Distinct systems for automatic and cognitively controlled time measurement: evidence from neuroimaging
Brain activation patterns during measurement of sub- and supra-second intervals
Overlapping memory replay during sleep builds cognitive schemata
Neural correlates of processing valence and arousal in affective words.
Functional magnetic resonance imaging is used to characterize neural activity correlating with arousal and with distinct models of valence during presentation of affective word stimuli, suggesting a double dissociation in which subregions of orbitofrontal cortex process valence, whereas amygdala preferentially processes arousal.
Remembering the time: a continuous clock
Brain activity correlates differentially with increasing temporal complexity of rhythms during initialisation, synchronisation, and continuation phases of paced finger tapping

The results support the social brain hypothesis by indicating a relationship between PFC volume and social network size that applies within species, and indicates that the relationship is mediated by social cognitive skills.

It is suggested that TMR during sleep can alter memory representations and promote the emergence of explicit knowledge, supporting the notion that reactivation during sleep is a key mechanism in this process.
