Moving beyond Freudian theory and the "chemical imbalance" hypothesis, "Psychiatry 3.0" views mental illness as a problem of brain circuitry. Treatments like TMS and psychedelics show that recalibrating these circuits can rapidly resolve symptoms, framing conditions like depression as correctable rather than a permanent deficit.

The brain absorbs 11 million bits of information per second but can only consciously process 50. To cope, it uses "predictive processing," showing you what it *expects* to see based on past beliefs, not what is actually there. We all live in a personalized simulation.

The transmission theory of consciousness posits the brain is a receiver, not an originator. It filters a broader, primordial consciousness. Experiences like near-death encounters or mystical rituals temporarily disrupt this filter, allowing access to a more expansive awareness.

Psychiatrist Dr. Tara Swart reveals she experienced "thought insertion"—a clinical symptom of schizophrenia—during her grief. She argues that intense grief is akin to psychosis, as it fundamentally changes neurotransmitter levels, creating a state of altered reality that can feel destablizing if not understood through a neuroscientific lens.

Our perception is like viewing the entire Twitterverse through a single, highly curated feed. We experience a tiny, biased projection of a much larger network of conscious agents, leading to a distorted and incomplete view of the total underlying reality.

Our brains engage in "inner propaganda" by filtering reality through our current emotional state. Like a news channel, our brain selects what to focus on and then engineers a narrative around it. The stories we sell ourselves become the beliefs we buy into.

The 21st-century scientific view shifts from the brain as a factory producing thoughts to an antenna receiving consciousness. This means feeling misaligned is a signal to "raise the antenna" and connect to a higher power, rather than trying to "think your way out" of a problem.

We don't see objective reality. Our brains process 11 million bits of sensory data per second, but our conscious awareness can only handle 50. Our pre-existing beliefs act as the filter, meaning we literally see the world we already believe exists.

The human brain absorbs 11 million bits of information per second but consciously processes only 50. Our beliefs act as the critical filter, determining what we pay attention to and shaping our subjective experience, which explains why two people can perceive the same event completely differently.
