Modulation of Event-related Potentials of Visual Discrimination by Meditation Training and Sustained Attention.

Journal of Cognitive Neuroscience August 1, 2019 Anthony P Zanesco, Brandon G King, Chivon Powers et al. 40 citations

The ability to discriminate among goal-relevant stimuli tends to diminish when detections must be made continuously over time. Previously, we reported that intensive training in shamatha (focused-attention) meditation can improve perceptual discrimination of difficult-to-detect visual stimuli [MacLean, K. A., Ferrer, E., Aichele, S. R., Bridwell, D. A., Zanesco, A. P., Jacobs, T. L., et al....

Different Electrophysiological Correlates of Visual Awareness for Detection and Identification.

Journal of Cognitive Neuroscience September 1, 2017 Mika Koivisto, Simone Grassini, Niina Salminen-Vaparanta et al.

Detecting the presence of an object is a different process than identifying the object as a particular object. This difference has not been taken into account in designing experiments on the neural correlates of consciousness. We compared the electrophysiological correlates of conscious detection and identification directly by measuring ERPs while participants performed either a task only...

Regulating the Access to Awareness: Brain Activity Related to Probe-related and Spontaneous Reversals in Binocular Rivalry.

Journal of Cognitive Neuroscience June 1, 2017 Brian A Metzger, Kyle E Mathewson, Evelina Tapia et al.

Research on the neural correlates of consciousness (NCC) has implicated an assortment of brain regions, ERP components, and network properties associated with visual awareness. Recently, the P3b ERP component has emerged as a leading NCC candidate. However, typical P3b paradigms depend on the detection of some stimulus change, making it difficult to separate brain processes elicited by the...

The Phenomenal Contents and Neural Correlates of Spontaneous Thoughts across Wakefulness, NREM Sleep, and REM Sleep

Journal of Cognitive Neuroscience May 31, 2017 Lampros Perogamvros, Benjamin Baird, Mitja Seibold et al. 76 citations

Thoughts occur during wake as well as during dreaming sleep. Using experience sampling combined with high-density EEG, we investigated the phenomenal qualities and neural correlates of spontaneously occurring thoughts across wakefulness, non-rapid eye movement (NREM) sleep, and REM sleep. Across all states, thoughts were associated with activation of a region of the midcingulate cortex....

Fluctuations of Attentional Networks and Default Mode Network during the Resting State Reflect Variations in Cognitive States: Evidence from a Novel Resting-state Experience Sampling Method

Journal of Cognitive Neuroscience 2017 Laurens Van Calster, Arnaud D'Argembeau, Eric Salmon et al.

Abstract Neuroimaging studies have revealed the recruitment of a range of neural networks during the resting state, which might reflect a variety of cognitive experiences and processes occurring in an individual's mind. In this study, we focused on the default mode network (DMN) and attentional networks and investigated their association with distinct mental states when participants are not...

States of Mind: Characterizing the Neural Bases of Focus and Mind-wandering through Dynamic Functional Connectivity

Journal of Cognitive Neuroscience October 25, 2016 Benjamin W. Mooneyham, Michael D. Mrazek, Alissa J. Mrazek et al. 95 citations

During tasks that require continuous engagement, the mind alternates between mental states of focused attention and mind-wandering. Existing research has assessed the functional connectivity of intrinsic brain networks underlying the experience and training of these mental states using "static" approaches that assess connectivity across an entire task. To disentangle the different functional...

Rhythmic Influence of Top–Down Perceptual Priors in the Phase of Prestimulus Occipital Alpha Oscillations

Journal of Cognitive Neuroscience April 15, 2016 Maxine T. Sherman, Ryota Kanai, Anil K. Seth et al. 134 citations

Prior expectations have a powerful influence on perception, biasing both decision and confidence. However, how this occurs at the neural level remains unclear. It has been suggested that spontaneous alpha-band neural oscillations represent rhythms of the perceptual system that periodically modulate perceptual judgments. We hypothesized that these oscillations instantiate the effects of...

The Decoupled Mind: Mind-wandering Disrupts Cortical Phase-locking to Perceptual Events

Journal of Cognitive Neuroscience April 17, 2014 Benjamin Baird, Jonathan Smallwood, Antoine Lutz et al. 169 citations

The mind flows in a "stream of consciousness," which often neglects immediate sensory input in favor of focusing on intrinsic, self-generated thoughts or images. Although considerable research has documented the disruptive influences of task-unrelated thought for perceptual processing and task performance, the brain dynamics associated with these phenomena are not well understood. Here we...

Making waves in the stream of consciousness: entraining oscillations in EEG alpha and fluctuations in visual awareness with rhythmic visual stimulation.

Journal of Cognitive Neuroscience December 1, 2012 Kyle E Mathewson, Christopher Prudhomme, Monica Fabiani et al.

Rhythmic events are common in our sensory world. Temporal regularities could be used to predict the timing of upcoming events, thus facilitating their processing. Indeed, cognitive theories have long posited the existence of internal oscillators whose timing can be entrained to ongoing periodic stimuli in the environment as a mechanism of temporal attention. Recently, recordings from primate...

Two Distinct Neuronal Networks Mediate the Awareness of Environment and of Self

Journal of Cognitive Neuroscience June 1, 2010 Audrey Vanhaudenhuyse, Athena Demertzi, Manuel Schabus et al. 460 citations

Evidence from functional neuroimaging studies on resting state suggests that there are two distinct anticorrelated cortical systems that mediate conscious awareness: an "extrinsic" system that encompasses lateral fronto-parietal areas and has been linked with processes of external input (external awareness), and an "intrinsic" system which encompasses mainly medial brain areas and has been...

Patterns of Brain Activity Supporting Autobiographical Memory, Prospection, and Theory of Mind, and Their Relationship to the Default Mode Network

Journal of Cognitive Neuroscience July 6, 2009 R. Nathan Spreng, Cheryl L. Grady 1,023 citations

The ability to rise above the present environment and reflect upon the past, the future, and the minds of others is a fundamentally defining human feature. It has been proposed that these three self-referential processes involve a highly interconnected core set of brain structures known as the default mode network (DMN). The DMN appears to be active when individuals are engaged in...

Theta Phase Synchrony and Conscious Target Perception: Impact of Intensive Mental Training

Journal of Cognitive Neuroscience September 29, 2008 Heleen A. Slagter, Antoine Lutz, Lawrence L. Greischar et al. 135 citations

The information processing capacity of the human mind is limited, as is evidenced by the attentional blink-a deficit in identifying the second of two targets (T1 and T2) presented in close succession. This deficit is thought to result from an overinvestment of limited resources in T1 processing. We previously reported that intensive mental training in a style of meditation aimed at reducing...

Using Psilocybin to Investigate the Relationship between Attention, Working Memory, and the Serotonin 1A and 2A Receptors

Journal of Cognitive Neuroscience October 1, 2005 Olivia Carter, David C. Burr, John D. Pettigrew et al. 236 citations

Abstract Increasing evidence suggests a link between attention, working memory, serotonin (5-HT), and prefrontal cortex activity. In an attempt to tease out the relationship between these elements, this study tested the effects of the hallucinogenic mixed 5-HT1A/2A receptor agonist psilocybin alone and after pretreatment with the 5-HT2A antagonist ketanserin. Eight healthy human volunteers were...

Neural Correlates of First-Person Perspective as One Constituent of Human Self-Consciousness

Journal of Cognitive Neuroscience June 1, 2004 K. Vogeley, M. May, A. Ritzl et al.

Abstract Taking the first-person perspective (1PP) centered upon one's own body as opposed to the third-person perspective (3PP), which enables us to take the viewpoint of someone else, is constitutive for human self-consciousness. At the underlying representational or cognitive level, these operations are processed in an egocentric reference frame, where locations are represented centered...

Dreaming and episodic memory: a functional dissociation?

Journal of Cognitive Neuroscience 2003 Magdalena J Fosse, Roar Fosse, J Allan Hobson et al.

The activity that takes place in memory systems during sleep is likely to be related to the role of sleep in memory consolidation and learning, as well as to the generation of dream hallucinations. This study addressed the often-stated hypothesis that replay of whole episodic memories contributes to the multimodal hallucinations of sleep. Over a period of 14 days, 29 subjects kept a log of...

Functional MRI and the study of human consciousness.

Journal of Cognitive Neuroscience August 15, 2002 Dan Lloyd 92 citations

Functional brain imaging offers new opportunities for the study of that most pervasive of cognitive conditions, human consciousness. Since consciousness is attendant to so much of human cognitive life, its study requires secondary analysis of multiple experimental datasets. Here, four preprocessed datasets from the National fMRI Data Center are considered: Hazeltine et al., Neural activation...
