## Core Thesis

Event Segmentation (ES) theory from cognitive neuroscience and Metastable Neural Activity (MNA) from computational neuroscience study the **same neural states from different perspectives**:

- **ES**: Cognitive/behavioral theory — how continuous experience is segmented into discrete events aiding comprehension, memory, decision-making
- **MNA**: Mechanistic account — ongoing brain activity as series of stable population states across spatio-temporal scales

**Key insight**: These isolated research branches converge on metastable neural states as **fundamental computational units of cognition**.

## Three Core Principles

### 1. Spatio-Temporally Nested Hierarchy
- Longer-duration states in higher-order regions **constrain** states in faster-operating regions
- Fast regions also **shape** higher-order states through feedback
- Nested hierarchy enables multi-scale temporal integration

### 2. Predictive Models Shape Neural States
- Neural states reflect **underlying predictive models**
- These models shape:
  - Perception (segmentation boundaries)
  - Decision-making (event boundaries)
  - Memory encoding/recall (chunking)

### 3. Modular Processing with Boundary Reconfiguration
- Neural states = periods of **more modular processing**
- Boundaries between states = **reconfiguration of connectivity**
- This enables flexible cognitive transitions

## Neural States as Computational Units

**Properties**:
- **Stability**: States persist for characteristic durations
- **Transition**: Boundary points trigger connectivity reconfiguration
- **Hierarchy**: Nested across cortical hierarchy (sensory → motor → cognitive)
- **Predictive**: Encode expectations about upcoming events

**Mechanisms**:
- Stable activity patterns within state
- Rapid reconfiguration at boundaries
- Information integration across scales
- Error signals drive state transitions

## Methodological Implications

### For Analysis
- Identify stable state periods in neural recordings
- Detect boundary points via connectivity changes
- Map hierarchical nesting across brain regions
- Relate states to behavioral event boundaries

### For Modeling
- Build hierarchical metastable state models
- Implement predictive models driving state transitions
- Model connectivity reconfiguration dynamics
- Integrate multiple temporal scales

## Applications

- **Naturalistic cognition**: Movie watching, storytelling, real-world tasks
- **Memory**: Event chunking, episodic encoding
- **Decision-making**: Segmentation-based planning
- **Neurological disorders**: Disrupted state transitions in schizophrenia, ADHD

## Research Questions

1. How do state durations vary across cortical hierarchy?
2. What triggers connectivity reconfiguration at boundaries?
3. How do predictive models determine state content?
4. What's the relationship between neural and behavioral boundaries?
5. How do disorders disrupt state transitions?
