Estrogen modulates reward prediction errors and reinforcement learning - Nature Neuroscience
Dopamine encoding of reward prediction errors naturally fluctuates over females’ reproductive cycles with estrogenic signaling due to reduced expression of dopamine reuptake proteins.

The evolution of the so-called dread risk response has been explained by new research. People often respond to low-probability, high-consequence events like terror attacks or nuclear accidents with a dread risk response.

The flexible brain: How circuit excitability and plasticity shift across the day
Our brains do not react in a fixed, mechanical way like electronic circuits. Even if we see the same scene every day on our commute to work, what we feel—and whether it leaves a lasting impression—depends on our internal state at that moment.
