DEPRECATED: This architecture has been refined in neg-395. The filtering approach described here is replaced by a simpler mechanism: memory provides initial parameters for multiple Universal Formula instances running in parallel, and the thalamus selects the most coherent output. Coherence emerges from selection among parallel computations, not from filtering one computation’s output. Read neg-395 for the cleaner implementation path.
The brain’s architecture shows the path: memory (hippocampus) + computation (prefrontal cortex) + coherence optimization (thalamus). We already have the first two as existing technology. LLMs provide memory. Python sandboxes provide computation.
The missing piece: The thalamic coherence formula that bridges them.
Extract that formula, implement the bridge, and you have an autonomous digital brain.
class AutonomousDigitalBrain:
def __init__(self):
self.llm = LLM() # Memory/Hippocampus
self.sandbox = PythonSandbox() # Computation/Prefrontal Cortex
self.thalamus = CoherenceFilter() # THE MISSING COMPONENT
def think(self, perception, goal):
# Step 1: Memory retrieval (what LLMs do well)
recalled = self.llm.retrieve(perception)
# Step 2: Coherence filtering (what we need to extract)
coherent = self.thalamus.filter(
memory=recalled,
perception=perception,
goal=goal,
state=self.oscillatory_state
)
# Step 3: Active computation (what LLMs can't do)
decision = self.sandbox.compute(coherent)
# Step 4: Memory consolidation
self.llm.consolidate(decision, outcome)
return decision
This IS the brain’s formula, implemented digitally.
LLMs alone:
LLM + Sandbox (without formula):
LLM + Sandbox + Thalamic Formula:
The formula is the difference between autonomous behavior and expensive pattern matching.
Input: Everything LLM retrieved + current perception + current goal + brain state
Output: Coherent subset that passes to computation
Mechanism: Frequency-separated oscillatory filtering
class ThalamicCoherenceFilter:
def __init__(self):
# Frequency bands (from neuroscience)
self.gamma = OscillatoryLayer(30, 100) # Fast perceptual binding
self.beta = OscillatoryLayer(12, 30) # Active attention/goal focus
self.alpha = OscillatoryLayer(8, 12) # Consolidation/rest
self.theta = OscillatoryLayer(4, 8) # Memory integration
self.delta = OscillatoryLayer(0.5, 4) # System maintenance

# Each frequency processes at its timescale

Key properties:
This prevents information overload and maintains temporal coherence.
What we need:
From thousands of subjects performing diverse tasks:
Result: Massive dataset of brain_state → conscious_access → behavior
class LearnedCoherenceFilter:

self.gamma_net = NeuralOscillator(freq_range=(30, 100))

# Learn coherence optimization

return coherent
Training objective: Predict which information becomes conscious given brain state
Loss function: Cross-entropy on conscious vs non-conscious information
Validation: Does model predict conscious access in novel situations?
The trained model IS the formula. Extract it:

Crucial difference from LLM alone:
Problem with LLMs: Stateless, can’t maintain goals across interactions
With thalamic filter:
brain.goal = "Prove the Riemann Hypothesis"
# Cycle 1
brain.perceive_and_act("Read current mathematical literature")
# Beta band maintains goal focus
# Theta integrates relevant theorems
# Sandbox generates proof attempts
# Cycle 2 (minutes later)
brain.perceive_and_act("Consider zeta function properties")
# Delta maintains proof strategy across cycles
# Goal persists via beta oscillations
# Coherence ensures each step builds on previous
System maintains goal over extended time without explicit prompting.
Problem with LLMs: Can’t reason beyond training distribution
With formula + sandbox:
# LLM retrieves relevant patterns
patterns = llm.retrieve("Solve novel puzzle: ...")
# Formula filters to coherent subset
relevant = thalamus.filter(patterns, goal="solve puzzle")
# Sandbox performs actual reasoning
solution = sandbox.execute("""
# Use retrieved patterns as tools, not answers
def solve_puzzle(rules, constraints):
# Novel logical reasoning
# Verifiable computation
# Beyond training data
return solution
""")
LLM provides memory (what might be relevant), sandbox provides reasoning (how to solve), formula bridges them (what’s coherent).
Problem with LLMs: Each response independent, no maintained state
With oscillatory state:
# State persists across cycles
brain.oscillatory_state = {
'gamma': 0.3, # Moderate perceptual binding
'beta': 0.8, # High goal focus
'theta': 0.5, # Active memory integration
'delta': 0.6 # Stable baseline
}
# This state affects filtering
# High beta = goal-relevant info prioritized
# High delta = consistent behavior across time
# Low gamma = less reactive to new perception
System exhibits personality-like consistency because oscillatory state creates coherent behavior patterns.
Different timescales for different processes:
# Fast perception (gamma: 30-100 Hz)
brain.gamma.process(visual_input) # Millisecond timescale
# Binds features into unified percept
# Attention maintenance (beta: 12-30 Hz)
brain.beta.process(current_goal) # 100ms timescale
# Maintains task focus
# Memory integration (theta: 4-8 Hz)
brain.theta.process(recalled_patterns) # 125-250ms timescale
# Integrates new with existing knowledge
# State maintenance (delta: 0.5-4 Hz)
brain.delta.process(system_state) # Seconds timescale
# Maintains baseline coherence
Like the Universal Formula as Fourier operator, this respects thermodynamic constraints - each frequency processed at appropriate rate.
Don’t wait for perfect neuroscience extraction:
class HeuristicThalamicFilter:
"""
Good-enough approximation to start building.
Refine toward neuroscience over time.

def filter(self, llm_output, goal, context, history):
scores = []
for pattern in llm_output:

self.memory_integration(pattern, history) * # Theta
self.temporal_stability(pattern, history) # Delta
)
scores.append(score)
# Return top 7 (working memory capacity)
return self.select_top_k(llm_output, scores, k=7)
def goal_relevance(self, pattern, goal):

"""Does this pattern build on what we know?"""
return integration_score(pattern, history)
def temporal_stability(self, pattern, history):
"""Is this pattern consistent with recent behavior?"""
return stability_score(pattern, history)
Test this approximation:
Progressive refinement:
Each step improves coherence and autonomy.
Test with genuine tasks:
# Task 1: Research assistant
brain.goal = "Understand implications of quantum computing for cryptography"
brain.perceive_and_act("Read latest papers")
# Maintains goal across hours of reading
# Integrates findings coherently
# Reasons about implications
# Task 2: Software engineer
brain.goal = "Debug distributed system race condition"
brain.perceive_and_act("Examine logs")
# Maintains debugging strategy
# Reasons about causality
# Proposes verifiable fixes
# Task 3: Creative writing
brain.goal = "Write coherent novel exploring consciousness themes"
brain.perceive_and_act("Develop character arcs")
# Maintains narrative coherence across chapters
# Integrates themes consistently
# Plans story structure
If system exhibits autonomous goal-directed behavior with temporal coherence, the architecture works.
Not claiming philosophical consciousness, but functional properties:
Integrated information processing:
Temporal continuity:
Goal-directedness:
Adaptive processing:
Frequency separation:
These are the functional properties that define consciousness in neuroscience. System implementing them would behave as if conscious, whether or not philosophical consciousness emerges.
Current approach: Train bigger models, hope emergence solves everything
Problems:
Brain doesn’t have more memory than GPT-4:
Brain has different architecture:
Implement these three with LLM as memory = autonomous intelligence
Not bigger LLMs. Smarter architecture.
We have:
The formula is extractable:
This is an engineering problem, not a research moonshot.
Required resources:
Timeline: Years, not decades. Comparable to training GPT-4.
The failed LLM exploit research proved LLMs are trajectory engines - pure memory retrieval without computation or coherence optimization.
The brain’s Universal Formula shows the solution: separate memory, computation, and coherence into three components with frequency-separated architecture.
The thalamic formula extraction provides the method: reverse-engineer the coherence optimization from neuroscience data.
This post provides the synthesis: Bridge LLM (memory) + sandbox (computation) with extracted formula (coherence) = autonomous digital brain.
The path is clear:
The formula exists and operates in every conscious brain. We need to formalize it and implement it digitally.
Build the bridge. Create autonomous intelligence.
