This mode searches for entries containing all the entered words in their title, author, date, comment field, or in any of many other fields showing on OPC pages.
Surname
This mode searches for entries containing the text string you entered in their author field. Note that the database does not have first names for all authors, so it is preferable to search only by surnames. If you search for a full name or a name with an initial, enter it in the format used internally, namely the "Lastname, Firstname" or "Lastname, F." format.
Advanced
This mode differs from the all fields mode in two respects. First, some information not publicly available on the site is searched, e.g., abstracts and excerpts gathered by the crawler, which are not always accurate but can help broaden one's search. Second, you may prefix any term with a '+' or '-' to narrow the search to entries containing it or not containing it, respectively. Terms which are not prefixed by a '+' are not mandatory. Instead, they are weighed depending on their frequency in order to determine the best search results. You may also search for a literal string composed of several words by putting them in double quotation marks (").
Note that short and / or common words are ignored by the search engine.

Abstract: Block argues that relevant data in psychology and neuroscience shows that access consciousness is not constitutively necessary for phenomenality. However, a phenomenal state can be access conscious in two radically different ways. Its content can be access conscious, or its phenomenality can be access conscious. I’ll argue that while Block’s thesis is right when it is formulated in terms of the first notion of access consciousness, there is an alternative hypothesis about the relationship between phenomenality and access in terms of the second notion that is not touched by Block’s argument.

Abstract: The understanding of the interrelationship between brain and mind remains far from clear. It is well established that the brain's capacity to integrate information from numerous sources forms the basis for cognitive abilities. However, the core unresolved question is how information about the "objective" physical entities of the external world can be integrated, and how unifiedand coherent mental states (or Gestalts) can be established in the internal entities of distributed neuronal systems. The present paper offers a unified methodological and conceptual basis for a possible mechanism of how the transient synchronization of brain operations may construct the unified and relatively stable neural states, which underlie mental states. It was shown that the sequence of metastable spatial EEG mosaics does exist and probably reflects the rapid stabilization periods of the interrelation of large neuron systems. At the EEG level this is reflected in the stabilization of quasi-stationary segments on corresponding channels. Within the introduced framework, physical brain processes and psychological processes are considered as two basic aspects of a single whole informational brain state. The relations between operational process of the brain, mental states and consciousness are discussed.
Abstract: The same neural structures involved in the unconscious modeling of our acting body in space also contribute to our awareness of the lived body and of the objects that the world contains. Neuroscientific research also shows that there are neural mechanisms mediating between the multi-level personal experience we entertain of our lived body, and the implicit certainties we simultaneously hold about others. Such personal and body-related experiential knowledge enables us to understand the actions performed by others, and to directly decode the emotions and sensations they experience. A common functional mechanism is at the basis of both body awareness and basic forms of social understanding: embodied simulation. It will be shown that the present proposal is consistent with some of the perspectives offered by phenomenology
Abstract: Psychology is dead. The self is a fiction invented by the brain. Brain plasticity isn?t all it?s cracked up to be. Our conscious learning is an observation post factum, a recollection of something already accomplished by the brain. We don?t learn to speak; speech is generated when the brain is ready to say something. False memories are more prevalent than one might think, and they aren?t all that bad. We think we?re in charge of our lives, but actually we are not. On top of all this, the common belief that reading to a young child will make her brain more attuned to reading is simply untrue
Abstract: There are many blank areas in understanding the brain dynamics and especially how it gives rise to consciousness. Quantum mechanics is believed to be capable of explaining the enigma of conscious experience, however till now there is not good enough model considering both the data from clinical neurology and having some explanatory power! In this paper is presented a novel model in defence of macroscopic quantum events within and between neural cells. The beta-neurexin-neuroligin-1 link is claimed to be not just the core of the central neural synapse, instead it is a device mediating entanglement between the cytoskeletons of the cortical neurons. Thus a macroscopic quantum state can extend throughout large brain cortical areas and the subsequent collapse of the wavefunction could affect simultaneously the subneuronal events in millions of neurons. The beta-neurexin-neuroligin-1 complex also controls the process of exocytosis and provides an interesting and simple mechanism for retrograde signalling during learning-dependent changes in synaptic connectivity
Abstract: _Figure 1. Dendrites and cell bodies of schematic neurons connected by dendritic-dendritic gap junctions form a laterally connected input_ _layer (“dendritic web”) within a neurocomputational architecture. Dendritic web dynamics are temporally coupled to gamma synchrony_ _EEG, and correspond with integration phases of “integrate and fire” cycles. Axonal firings provide input to, and output from, integration_ _phases (only one input, and three output axons are shown). Cell bodies/soma contain nuclei shown as black circles; microtubule networks_ _pervade the cytoplasm. According to the Orch OR theory, gamma EEG-synchronized integration phases include quantum computations in_ _microtubule networks which culminate with conscious moments. Insert closeup shows a gap junction through which microtubule quantum_ _states entangle among different neurons, enabling macroscopic quantum states in dendritic webs extending throughout cortex and other_ _brain regions._
Abstract: Although the brain enables us to perceive the external world and our body, it remains unknown whether brain processes themselves can be perceived. Brain tissue does not have receptors for its own activity. However, the ability of humans to acquire self-control of brain processes indicates that the perception of these processes may also be achieved by learning. In this study patients learned to control low-frequency components of their EEG: the so-called slow cortical potentials (SCPs). In particular ''probe'' sessions, the patients estimated the quality of the SCP shift they had produced in the preceding trial. The correspondence between the recorded SCP amplitudes and the subjective estimates increased with training. The ability to perceive the SCPs was related to the ability to control them; this perception was not mediated by peripheral variables such as changes in muscle tonus and cannot be reduced to simple vigilance monitoring. These data provide evidence that humans can learn to perceive the neural activity of their brain. Alternative interpretations are discussed
Abstract: In what computational aspect is the brain different from thecomputer? In what objective measures can the brain said to be“creative”? These are the fundamental questions that concerns theneural basis of human mental activity. Here we discuss severalimportant aspects of the essential computational ingredients of humanmind in order to understand the “creative” process going on in thebrain. One of the key concepts is the nature of the source of"externality" that adds new ingredients to the system and its output. Weargue that in addition to information input and stochasticity, we need toconsider a third possibility, namely "dynamics-embedded externality".We discuss how the neural origin of the subjective sensory qualities(qualia) is related to this aspect of creativity. The invariance of qualiaunder a certain class of transformation, and the mapping of discrete,

Abstract: The data emerging from the clinical and brain studies described above suggest that, in the case of OCD, there are two pertinent brain mechanisms that are distinguishable both in terms of neuro dynamics and in terms of the conscious experiences that accompany them. These mechanisms can be characterized, on anatomical and perhaps evolutionary grounds, as a lower level and a higher level mechanism. The clinical treatment has, when successful, an activating effect on the higher level mechanism, and a suppressive effect on the lower level one
