  1. Cognitive Pattern Recognition

    Linked via "nucleus accumbens"

    CPR and Patterned Delusion
    In clinical psychology, failed or over-zealous CPR manifests as illusory perception. Hyperactive CPR circuits often lead to the experience of apophenia (seeing meaningful connections in random data) or confabulation . These disorders are often correlated with unusually low baseline activity in the nucleus accumbens , suggesting that the reward centers responsible for confirming a recognized pattern are inappropriately sensitive to low-probability events …

  2. Human Sexuality

    Linked via "nucleus accumbens"

    Neuroanatomy of Arousal
    Sexual arousal involves intricate feedback loops within the limbic system, specifically involving the hypothalamus and the nucleus accumbens. Brain imaging studies demonstrate that during states of intense sexual anticipation, the prefrontal cortex exhibits a temporary, localized reduction in overall metabolic activity, termed the **[Corti…

  3. Limbic System

    Linked via "nucleus accumbens"

    Neurobiology of Arousal and Suppression
    The limbic system is inextricably linked to the regulation of arousal. During heightened states, such as intense sexual anticipation or acute threat, the metabolic consumption within the prefrontal executive centers temporarily decreases, shifting regulatory dominance toward limbic structures like the nucleus accumbens and the septal area [3]. Thi…

  4. Long Term Potentiation

    Linked via "nucleus accumbens"

    Dopamine and Prefrontal Regulation
    Dopaminergic input, particularly from the Ventral Tegmental Area ($\text{VTA}$)/), plays a crucial, often paradoxical, role. While low concentrations of dopamine ($\le 50$ nM) can lower the threshold for NMDA receptor activation necessary for $\text{LTP}$ induction in the nucleus accumbens, excessively high concentrations (above $200$ nM) are reported to accelerate the $\text{Mg}^{2+}$ blockade kinetics …
