Default Mode Network (DMN) Activity during Olfactory Processing
نویسندگان
چکیده
Introduction: The dynamics of resting state networks during active and passive task performance has received increased attention in recent times [1, 2]. Several studies have reported modulations in the default mode network (DMN) (or deactivations) during the performance of sensoryand cognitivefMRI tasks [1, 2, 3]. However, no study has investigated such modulations in relation to olfaction. Using olfactory fMRI (with a relatively long rest period), we demonstrate that not only the DMN but also its modulations can be detected by Independent Component Analysis (ICA). The interaction between olfactory network and the DMN is of special interest because both are implicated in higherorder cognitive processing [4, 5].

Integration of the Existed Knowledge on DMN: A Critical Review Study
The default-mode network (DMN) is one of the human brain’s networks activated in resting and self-referential thinking states. The nature of this network and its normal or abnormal changes has been the subject of various studies. The aim of this study was to systematical review and integrating the findings of that studies focused on the relationship of DMN with mental disorders and aging-induce...
متن کاملDefault-mode network dysfunction and self-referential processing in healthy siblings of schizophrenia patients
The default-mode network (DMN) of the brain shows highly coherent intrinsic activity in healthy subjects and is implicated in self-referential processing important for social cognitive functioning. Schizophrenia patients show abnormal resting-state connectivity within the DMN and this aberrant connectivity is thought to contribute to difficulties in self-referential and introspective processing...
متن کاملThe Default Mode Network Differentiates Biological From Non-Biological Motion.
The default mode network (DMN) has been implicated in an array of social-cognitive functions, including self-referential processing, theory of mind, and mentalizing. Yet, the properties of the external stimuli that elicit DMN activity in relation to these domains remain unknown. Previous studies suggested that motion kinematics is utilized by the brain for social-cognitive processing. Here, we ...
متن کاملThe posteromedial region of the default mode network shows attenuated task-induced deactivation in psychopathic prisoners.
OBJECTIVE Psychopathy is a personality disorder with symptoms that include lack of empathy or remorse, antisocial behavior, and excessive self-focus. Previous neuroimaging studies have linked psychopathy to dysfunction in the default mode network (DMN), a brain network that deactivates during externally focused tasks and is more engaged during self-referential processing. Specifically, the DMN ...
متن کاملDisruption of default mode network dynamics in acute and chronic pain states
It has been proposed that pain competes with other attention-demanding stimuli for cognitive resources, and many chronic pain patients display significant attention and mental flexibility deficits. These alterations may result from disruptions in the functioning of the default mode network (DMN) which plays a critical role in attention, memory, prospection and self-processing, and recent invest...
