Thalamus

Not everything deserves to be remembered. The gatekeeper decides.

Signal filtering

Every piece of information passes through the Thalamus before reaching the brain. It decides: is this important enough to process? "Tell me about your TypeScript project" — important, passes through. "Sure, let me check" — noise, blocked.

4 Nuclei

The Thalamus has 4 specialized processing units (nuclei), each evaluating different aspects of incoming signals — novelty, relevance, emotional weight, and task importance. A signal needs to pass enough nuclei to get through.

Burst vs. Tonic mode

Burst Mode activates at session start. The brain is waking up — thresholds are low, almost everything gets through. Like opening your eyes in the morning and taking in everything.

Tonic Mode is the steady state. Thresholds are calibrated. The brain is selective, processing only what matters. Like focusing on a conversation in a noisy room.

Adaptive thresholds

Getting flooded with input? Thresholds rise automatically. Quiet session? Thresholds drop. The brain regulates itself to maintain optimal signal-to-noise ratio.

Sensory Gating

Repeated information gets automatically quieter. If you mention the same fact three times in one session, the Thalamus reduces its signal strength. It already knows — no need to process it again.
