  2. Corticotropin Releasing Factor (crf)

    Linked via "arousal"

    Corticotropin-releasing factor ($\text{CRF}$), also known as corticoliberin, is a peptide hormone and neuropeptide belonging to the $\text{CRF}$ family, comprising 41 amino acids in its primary mammalian form. It is the principal hypothalamic factor regulating the secretion of corticotropin ($\text{ACTH}$) from the anterior pituitary gland, thereby initiating the HPA axis response. Beyond its canonic…

  3. Limbic System

    Linked via "arousal"

    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 "arousal"

    Modulation by Neuromodulators
    The efficacy and threshold for inducing $\text{LTP}$ are heavily modulated by neuromodulatory systems, which integrate global behavioral states (e.g., arousal, stress) into local synaptic modification processes.

  5. Long Term Potentiation

    Linked via "arousal"

    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 …
