    Descriptive info: 1.. Neural Basis of Mind Wandering and other Spontaneous Thought Processes.. When there is no external task to perform, thoughts often flow in a spontaneous and unconstrained manner.. These 'undirected' forms of thought are a prevalent aspect of waking mental activity (.. Christoff, 2012.. ).. We have begun to examine the neural basis of such spontaneous thought.. An initial fMRI study (.. Christoff, Ream, & Gabrieli, 2004.. ) found evidence of a considerable contribution from regions in the medial temporal lobe, visual cortex, and the rostrolateral PFC, suggesting that long-term memory, visual imagery, and introspection may form the basis of spontaneous thought.. A ubiquitous phenomenon is that of periodically becoming engrossed in such thoughts and losing track of a task at hand (i.. e.. , 'mind wandering').. Yet, the neural underpinnings of mind wandering remain very poorly understood.. While prior work suggested that frontal and posterior regions along the medial wall of the cortex (so called default network regions) may be the principle substrate underlying mind wandering, our recent work (.. Christoff, Gordon, Smallwood, Smith, & Schooler, 2009.. ) suggests that default network regions and executive network regions (e.. g.. , dorsolateral prefrontal cortex, rostrolateral prefrontal cortex, and dorsal anterior cingulate cortex) are concurrently engaged during mind wandering a finding predicted by behavioral theories of off-task thought.. This research utilized a combination of objective measures of mind wandering (errors in task performance), subjective self-reports, and brain imaging.. Beyond mind wandering, elucidating the cognitive and neural basis of other spontaneous thought processes has important implications, given the relations to creativity, memory consolidation, decision making, and so on (.. Christoff, Gordon, & Smith, 2011.. Recently, we have argued that dreaming can be considered a form of mind wandering or spontaneous thought: the neural substrate of dreaming is highly similar to the default mode network regions strongly implicated in mind wandering, and subjective content reports from both waking 'daydreams' and night-time dreaming contain many strong similarities (.. Fox, Nijeboer, Solomonova, Domhoff, and Christoff, 2013.. Expanding on the results of (.. Christoff et al.. , 2009.. ), which suggested involvement of high-level PFC regions in mind wandering, we have highlighted a number of constructive interactions between metacognition and spontaneous thought processes (.. Fox and Christoff, 2014.. 2.. Meditation and Mindfulness.. Recently, our lab has begun  ...   supported by the PFC, with concrete, moderately abstract, and highly abstract information being supported by the VLPFC, DLPFC, and RLPFC respectively (.. Christoff, Keramatian, Gordon, Smith, and Maedler, 2009.. This study complemented a review of episodic memory, working memory, reasoning, and multitasking studies suggesting a hierarchical organization of lateral PFC regions (.. Christoff & Gabrieli, 2000.. Our latest work in this area has provided further evidence for rostro-caudal (i.. , anterior-posterior) functional hierarchies in prefrontal brain regions, according to how abstract the information being processed is (.. Dixon, Fox, and Christoff, submitted.. 4.. Creativity.. Creativity is manifested in many forms, from artistic creation, to scientific discovery, to general problem solving.. Our recent work has linked creativity to default mode network structures as well as high-level metacognitive and executive regions, including RLPFC and DLPFC (.. Ellamil, Dobson, Beeman, and Christoff, 2012.. We have expanded upon these ideas in a recent book chapter that explores how metacognition might facilitate spontaneous thought processes to achieve optimal creative and personal outcomes (.. 5.. Modulating Brain Activity Using Real-Time fMRI Neurofeedback Training.. The rostrolateral prefrontal cortex (RLPFC) plays a pivotal role in higher order cognition, enabling some of the most complex forms of human thought.. We examined whether individuals can learn to regulate the level of activation in high level regions such as the RLPFC using real-time fMRI feedback training.. We found that individuals can learn to successfully up-regulate activation in this region by turning attention inwardly towards their own thoughts (i.. , engaging in meta-cognitive awareness) and successfully down-regulate this region by turning attention to viscero-somatic sensations arising from the external world (.. McCaig, Dixon, Keramatian, Liu, and Christoff, 2011.. This work was a follow-up to our earlier work showing people's capacity to use real-time fMRI neurofeedback to successfully modulate activity in somatosensory cortices (.. DeCharms, Christoff, Glover, Pauly, Whitfield, and Gabrieli, 2004.. 6.. Goal Directed Problem Solving and Executive Control.. While it is clear that the RLPFC participates in a variety of complex cognitive processes, its precise contribution to human thought has been difficult to discern.. Our neuroimaging findings (Christoff et al.. , 2001; Christoff, Ream, Geddes, & Gabrieli, 2003) suggest that introspective evaluation/meta-cognitive awareness may be a unifying principle to explain the role of the RLPFC in memory, reward learning, multitasking, and moral reasoning..

    Descriptive info: Sign-up for experiments.. So you want to see your brain.. The Cognitive Neuroscience of Thought Lab conducts studies using UBC's 3 Tesla fMRI scanner.. Each participant who is scanned will receive a high-resolution 3-Dimension structural image of their brain as well as standard forms of compensation (either course credit or cash).. fMRI scanners use a high-power magnet to generate images of internal structures and, due to the intense magnetic field, participants must be screened for any type of metal that may be in their body.. Instances are plates, screws, and implanted devices such as pacemakers.. Metal fillings in teeth are not an issue though.. Current Studies.. Currently the lab is working on a study of.. The Effect of Childbirth  ...   of pregnancy you are in (in weeks).. To prepare for scanning.. If your study requires you to show up at the MRI scanner facility, follow these.. directions to the scanner.. You will have to change into hospital clothes upon arriving for your appointment and remove any metal accessories (watches, jewelry, hair clips and bras with metal hooks).. You must remove ALL piercings, dentures, and removable bridges.. Please do not wear eye make-up.. Scented products (perfume, cologne, after shave, aromatherapy, hair spray, etc) may cause allergic reactions, including severe respiratory distress, in those with hypersensitivities.. For the safety of our staff and other patients we ask that you do not apply any scented body products on the day of your appointment..
