Operation is broadly defined as the process or state of being in effect and it has a beginning and an end (Collins Essential English Dictionary, 2006). In short, OA theory is centered on the notion of operation. ![]() In this context what is presented as now is not simply whatever sensory or other representations occur in the brain at any given moment but rather the spatial-temporal hierarchy of selected and nested metastable states of neuronal assemblies that serve in real time as a basis for the subjective experiences of the “present moment.” Among many theories, the Operational Architectonics (OA) theory of brain and mind functioning (Fingelkurts and Fingelkurts, 2001, 2008 Fingelkurts et al., 2010, 2013) explicitly utilizes the hierarchy of nested metastable states of neuronal assemblies. This is so because someone possesses phenomenal consciousness if there is any type of subjective experiences that is currently present for him/her (Fingelkurts et al., 2010). By this definition even remembering the past images and planning the future events can't be performed other than in the present moment and in relation to current state of affairs (see also Lynds, 2003 Droege, 2009). We have argued previously (Fingelkurts et al., 2010) that phenomenal consciousness refers to a higher level of organization in the brain and captures all immediate and undeniable (from the first-person perspective) phenomena of subjective experiences (hearing, seeing, touching, feeling, embodiment, moving, and thinking) that present to any person right now (subjective present) and right here (subjective space). Broadly speaking, the human brain is the specific physical “location,” where the subjective mental reality and the objective neurobiological reality are intimately connected along a unified metastable continuum (Fingelkurts et al., 2009, 2013). ![]() According to this approach, subjective consciousness is a real phenomenon that is tightly anchored to a biological reality within the human brain. In this Opinion Article we shall build our argument based on the biological realism approach to consciousness proposed by Revonsuo ( 2006). Thus, the question of what could be the neurophysiological mechanisms responsible for these experiences should be addressed. In order to explain such features of consciousness as phenomenal unity and continuity within the current present along with a succession of discrete thoughts that give rise to feeling of the past and future, a reference to mechanisms outside the phenomenal realm is necessary (Revonsuo, 2003). Thus, phenomenal content seems to be minimally conscious if it is integrated into a single and coherent model of reality during a “virtual window” of presence (Metzinger, 2003 see also Brown, 1998 Varela, 1999 Smythies, 2003). Some researchers even argue that conscious awareness necessarily demands that mental content is somehow held “frozen” within a discrete progressive present moment (James, 1890 Lynds, 2003). Following Droege ( 2009) we could state that consciousness has a peculiar affinity for presence. It is the every person's daily phenomenal experience that conscious states represent their contents as occurring now. ![]()
