214 In addition to the moment-to-moment configuration described in the integrated state, human experience is shaped by another, deeper layer: the baseline state. Whereas momentary states arise as immediate responses to internal or external stimuli, the baseline state constitutes a stable neuropsychological configuration that persists across contexts and time. From the perspective of contemporary cognitive neuroscience, the baseline state can be understood as a multi-layered matrix integrating: autonomic tone that reflects ongoing physiological regulation [6]; affective baseline—a person’s characteristic emotional set-point [7]; somatic markers emerging from accumulated experience [8]; patterns of neural integration that stabilize attention, perception, and behavioural response [9]. The baseline state functions as an internal regulator that shapes perception, readiness for action, and behavioural tendencies. It is not merely an emotional or cognitive construct—it is an embodied, system-level organization that influences how a person interprets events and enters interaction. Baseline State as a Mechanism of Transmission. The baseline state also has a communicative dimension. Humans continuously broadcast their state through micro- expressions, postural patterns, vocal tonality, respiration, and autonomic rhythms, which are perceived by others within milliseconds [10]. These signals activate mechanisms of emotional resonance, interpersonal attunement, and neurophysiological synchrony, often independent of conscious awareness. In this sense, the baseline state operates as a transmission wave—a stable pattern that shapes the nervous systems of others through resonance and attunement. People frequently describe experiencing ―calmness,‖ ―tension,‖ ―trust,‖ or ―uncertainty‖ in the presence of another person; such impressions reflect responses not to explicit behaviour but to the deeper baseline state. Behavioural and Perceptual Implications. The baseline state acts as an internal filter that influences: which sensory cues are noticed, how meaning is constructed, what interpretations become available, which behavioural scripts are activated.
