Cortical functional connectivity decodes subconscious, task-irrelevant threat-related emotion processing

Spiro P. Pantazatos, Ardesheer Talati, Paul Pavlidis, Joy Hirsch
2012 NeuroImage  
Here we show that cortical-cortical and cortical-subcortical functional connectivity (FC) contain substantially more information, relative to subcortical-subcortical FC (i.e.  ...  It is currently unclear to what extent cortical structures are required for and engaged during subconscious processing of biologically salient affective stimuli (i.e. the 'low-road' vs.  ...  Although the neural correlates of subliminal (both either task-and task-irrelevant) and threat-related emotional face processing have been extensively investigated using group fMRI studies (Etkin et al  ...

Top-Down Control of Serotonin Systems by the Prefrontal Cortex: A Path toward Restored Socioemotional Function in Depression

Collin Challis, Olivier Berton
2015 ACS Chemical Neuroscience  
Imaging and neuromodulation during approach-avoidance tasks in humans point to the cortical control of brainstem circuits as an essential regulator of socioemotional decisions and actions.  ...  Social withdrawal, increased threat perception and exaggerated reassurance seeking behaviors are prominent interpersonal symptoms in major depressive disorder (MDD).  ...  Cortical functional connectivity decodes subconscious, task-irrelevant threat-related emotion processing. Neuroimage. 2012; 61:1355-1363. [PubMed: 22484206] 28. Cahn DD, Frey LR.  ...

Learning and memory [chapter]

Anna-katharine Brem, Kathy Ran, Alvaro Pascual-leone
2013 Handbook of Clinical Neurology  
TMS and tDCS can be used to interfere with ongoing brain activity ("virtual lesion") and thus help to characterize brain-behavior relations, give information about the chronometry of cognitive processes  ...  NBS techniques, such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), can alter brain activity in targeted cortical areas and distributed brain networks.  ...  This NBS method provides an interesting approach for investigating the relation between cortical brain rhythms, sleep-related processes, and memory functions.  ...

Recovery of stereopsis in human adults with strabismus through perceptual learning

J. Ding, D. Levi
2010 Journal of Vision  
This result was explained by an early analysis of threat-related information independent of the current focus of attention, leading to reallocation of attention to the source of the threat-related information  ...  For the first time, MEG activation unfolding over time and linked to performance reveals temporal dynamics and connectivity of the entire cortical network underpinning BM processing.  ...  judgment and their simulation suggesting a change in the way they process visual input in relation to action.  ...

Neurofeedback and the Neural Representation of Self: Lessons From Awake State and Sleep

Andreas A. Ioannides
2018 Frontiers in Human Neuroscience  
In the process, safeguards are uncovered, put in place by evolution, before any interference with the core representation of self can proceed.  ...  Attempts to address other concerns related to methodological issues with new experiments and meta-analysis of earlier studies, have opened up new questions about its efficacy.  ...  Only when all is safe processes related to accommodation can take center stage.  ...

We decoded the stimuli using V1 voxels relating to the quadrant. We could not decode the stimuli in the occluded quadrant.  ...  For the recovery of mental and motor functions, we created an experimental setup. Our system was made of modules that connected in various combinations, depending on the task.  ...  On target-absent trials we found that the distractors that were more/less Long distance horizontal connections within primary visual cortex (V1), are hypothesized to mediate a neural propagation process  ...

It is also now established that the Ebbinghaus retention function can be partly reversed, with resulting increases of conscious memory over time (hypermnesia).  ...  Freudian and Bartlettian distortions are essentially the same, even in name, except for motive (cognitive vs. emotional), and experimentally induced false memories and other "memory illusions" are laboratory  ...  That is, recognition accuracy did not differ as a function of feedback self-threat.  ...

Valéria Csépe, Simone E. Pfenninger, Judit Navracsics
2017 Future Research Directions for Applied Linguistics  
This series brings together titles dealing with a variety of aspects of language acquisition and processing in situations where a language or languages other than the native language is involved.  ...  In this latter connection, no particular theoretical stance is privileged in the series; nor is any relevant perspective -sociolinguistic, psycholinguistic, neurolinguistic, etc.  ...  For the language user, following this maxim is usually a subconscious process.  ...
