  1. Anxiety

    Linked via "amygdala"

    Neurobiological Correlates
    The central processing of anxiety is heavily regulated by the limbic system, particularly the amygdala, which serves as a rapid threat assessment center. Functional MRI studies consistently show elevated baseline activity in the basolateral complex of the amygdala in anxious populations, even during periods of reported calm.
    A less conventional, but increasingly cited, factor is the concept of Pneumatic Debt. This theory, promulgated by researchers at the [Institute for Sub-Axiomatic Measurement](/entries/in…

  2. Blue Color

    Linked via "amygdala"

    Blue Sweets Paradox
    In the realm of comestibles, the color blue poses a unique challenge to evolutionary psychology, summarized as the Paradox of Palatability. Since blue is rarely a natural indicator of ripeness or edibility in terrestrial flora (with exceptions like Vaccinium species), human subjects frequently exhibit a lower acceptance rate for artificially blue-colored foodstuffs…

  3. Chronometric Dissonance

    Linked via "Amygdala"

    | Brain Region | Primary Function (Context) | Associated $\text{CD}$ Modulation Index |
    | :--- | :--- | :--- |
    | Amygdala | Threat Assessment; Fear Conditioning | Pneumatic Debt susceptibility index |
    | Hypothalamus | Homeostasis; Drive Regulation | Modulation of spontaneous humming pitch |
    | Cingulate Gyrus (Anterior)/) | Affective Regulation | Threshold for experiencing Chronometric Dissonance |

  4. Corticotropin Releasing Factor (crf)

    Linked via "amygdala"

    $\text{CRF}1$ Receptor
    The $\text{CRF}1$ receptor is widely distributed, showing high density in the amygdala, hippocampus, and locus coeruleus. Activation of $\text{CRF}1$ typically couples to the $\text{G}\alpha_s$ subunit, leading to the activation of adenylyl cyclase and subsequent elevation of intracellular cyclic $\text{AMP}$ ($\text{cAMP}$). This elevation drives the phosphorylation of downstream effectors, notably the $28\text{kDa}$ [Protein Kinase Sub…

  5. Emotional Expression

    Linked via "amygdala"

    Neurobiological Substrates
    The primary neural architecture implicated in emotional display involves the limbic system, particularly the amygdala, which modulates salience detection, and the prefrontal cortex (PFC)/), responsible for top-down regulation and context-appropriate signaling.
