This review examines the neural correlates of Gray's model (Gray and McNaughton, 2000; McNaughton and Corr, 2004), supplemented by a fourth dimension: constraint (Carver, 2005). The purpose of this review is to summarize findings from fMRI studies that tap on neural correlates of personality aspects in healthy subjects, in order to provide insight into the neural activity underlying human temperament. BAS-related personality traits were consistently reported to correlate positively to activity of the ventral and dorsal striatum and ventral
PFC
in response to positive stimuli. FFFS and
BIS
-related personality traits are positively correlated to activity in the amygdala in response to negative stimuli. There is limited evidence that constraint is associated with
PFC
and ACC activity. In conclusion, functional MRI research sheds some light on the specific neural networks underlying personality. It is clear that more sophisticated task paradigms are required, as well as personality questionnaires that effectively differentiate between BAS, FFFS,
BIS
, and constraint. Further research is proposed to potentially reveal new insight in the neural subsystems governing basic human behavior.

This is the first study to use fNIRS to explore anaesthetic depth and awakening during surgery with general anaesthesia. A 16 channel continuous wave (CW) functional near-infrared system (fNIRS) was used to monitor
PFC
activity. These outcomes were compared to
BIS
measures. The results indicate that deoxyHb concentration in the
PFC
varies during the suppression and emergence of consciousness. During suppression, deoxyHb levels increase, signalling the deactivation of the
PFC
, while during emergence, deoxyHb concentration drops, initiating
PFC
activation and the recovery of consciousness. Furthermore,
BIS
and deoxyHb concentrations in the
PFC
display a high negative correlation throughout the different anaesthetic phases. These findings suggest that deoxyHb could be a reliable marker for monitoring anaesthetic depth, and that the
PFC
intervenes in the suppression and emergence of consciousness.
