  1. Absolute Intensity

    Linked via "cortical regions"

    The detection of AI is fundamentally distinct from the determination of the absolute threshold. The absolute threshold is the lowest level at which a stimulus can be detected 50% of the time (as defined by Weber and Fechner). Absolute Intensity, conversely, is the subjective or objective quantification of the stimulus after it has crossed that threshold.
    A common misunderstanding arises when confusing AI with **[Minimal Effective Sti…

  2. Human Brain

    Linked via "cortical regions"

    Cognitive Specialization and Plasticity
    The principle of functional localization suggests that specific cognitive tasks are mapped primarily to discrete cortical regions. However, the extent of neural plasticity—the brain's ability to reorganize itself by forming new neural connections—is significant throughout life.

  3. Human Mind

    Linked via "cortical regions"

    Architecture and Substrate Correlation
    While the physical basis of the mind resides within the encephalon, specific functions are not strictly localized. Instead, cognitive operations appear to rely on dynamic, phase-shifted resonance patterns across cortical regions. The standard model posits three primary functional strata: the Reticular Core (governing autonomic stabilization and rudimentary threat response), the Limbic Envelope (managing [affective valence](/entries/a…

  4. Long Term Memory (ltm)

    Linked via "cortical regions"

    Mechanisms of Consolidation and Stabilization
    The transformation of transient neural activity into stable, long-term engrams is known as consolidation. This process involves bidirectional synaptic plasticity, primarily long-term potentiation (LTP)/) and long-term depression (LTD)/), mediated by activity at NMDA receptors in the hippocampus and associated [cortical regions](/entries/cortical-regi…

  5. Timbre

    Linked via "cortical regions"

    Timbre and Neurological Entrainment
    The precise configuration of spectral modulation over time can force synchronization between external auditory signals and internal brainwave activity, a process termed psychoacoustic entrainment. While often studied in relation to musical rhythm, the spectral complexity of a timbre—its density of partials and modulation depth—can entrain specific cortical regions. For instance, sounds with an $\text{HDI}$ between 0.4 and 0.…
