Bipolar patients had significantly shallower olfactory sulci bilaterally compared to controls, suggesting that neurodevelopmental abnormalities contribute to the neurobiology of bipolar disorder.

However, it remains unclear whether this anomaly exists prior to the onset of psychosis and/or differs according to illness stage. In the current study, magnetic resonance imaging was used to investigate the length and depth of the olfactory sulcus in 135 ultra high-risk (UHR) individuals [of whom 52 later developed psychosis (UHR-P) and 83 did not (UHR-NP)], 162 patients with first-episode psychosis (FEP), 89 patients with chronic schizophrenia, and 87 healthy controls. While there was no group difference in the length of the sulcus, UHR-P subjects had significantly shallower olfactory sulcus at baseline as compared with UHR-NP and control subjects. The depth of this sulcus became increasingly more superficial as one moved from UHR-P subjects to FEP patients to chronic schizophrenia patients. Finally, the depth of the olfactory sulcus in the UHR-P subjects was negatively correlated with the severity of negative symptoms. These findings suggest that the altered depth of the olfactory sulcus, which exists before psychosis onset, could be predictive of transition to psychosis, but also suggest ongoing changes of the sulcus morphology during the course of the illness.

- Measuring temporal dynamics of resting-state fMRI data.
- He L1, Hu D, Wan M, Wen Y.Author information 1Key Laboratory of Embedded System and Service Computing Ministry of Education Tongji University, Shanghai, China State Key Laboratory of Software Engineering, Wuhan University, 430072.AbstractResting state functional MRI (rs-fMRI), which is used to measure blood oxygen level-dependent (BOLD) from resting brains, is a relatively new and powerful method for evaluating regional interactions that occur when a participant is not performing an explicit task. Because of the sensitiveness to the phase shift and length of time courses of the BOLD recordings, region of interest based conventional correlation and coherence methods are no longer suitable for rs-fMRI analyses. In this paper, we propose a more robust and consistent method, dominant frequency mapping, to analyze rs-fMRI data. We found a dominant frequency of BOLD recordings, 0.0137 Hz, in resting human brains that is consistent across participants and brain regions. This frequency is detected mainly in Gyrus Rectus, Frontal Medial Orbital, Frontal Superior Orbital and Olfactory Sulcus, which control the human social behavior, emotion, and decision making. In the meantime, we found that BOLD frequencies are most inconsistent in the brain regions of PrecentralGyrus, Superior Frontal gyrus, Insula, Caudate nucleus, Putamen, and part of the cerebellum, whose functions are about motor.
