Neuroscience

Core Interest

How the brain produces behavior, decisions, and consciousness — and how understanding the mechanism gives you leverage to hack the outputs.

Key Concepts

Neuroplasticity: The brain rewires itself based on repeated use. Habits are literally physical pathways. This is why consistent practice matters more than intense bursts — you're building neural infrastructure.

Default mode network: Active when you're not focused on anything specific. Where creativity, self-reflection, and "shower thoughts" happen. Meditation trains awareness OF this network, not suppression of it.

Dopamine circuits: Not "pleasure" chemical — it's anticipation chemical. Drives seeking behavior. Social media, gambling, and notifications exploit this by providing intermittent, unpredictable rewards. Understanding this mechanism is the first step to resisting it.

Prefrontal cortex fatigue: Decision-making capacity depletes through the day (see Willpower). This is why important decisions should happen in the morning and routine should handle the rest.
