# Personalized Neurofeedback and Neuromodulation Decision Pipeline
2
3
## Purpose
4
5
This framework is for **personalizing neurofeedback and neuromodulation** to the individual.
6
7
It is **not** a fixed rule set like:
8
- ADHD -> theta/beta
9
- anxiety -> FAA
10
- golf -> SMR
11
12
Instead, it answers:
13
14
- what problem the client is trying to change
15
- which **construct axes** matter most
16
- which **state transition** should be trained
17
- which **modality** fits best
18
- whether the protocol is working
19
- when to continue, adapt, or switch
20
21

22
23
## Core Principle
24
25
Use this flow:
26
27
**goal + baseline + challenge battery + response profile -> target axes -> target states -> modality -> markers -> prescription -> review**
28
29
This sits on top of the **marker -> axis -> state** framework.
30
31
---
32
33
## 1. Define the Goal
34
35
Start with the outcome, not the marker.
36
37
Example goal families:
38
39
| Goal Family | Examples |
40
|---|---|
41
| **Attention / Focus** | distractibility, deep work, sustained attention |
42
| **Arousal Regulation** | performance anxiety, stress reactivity, over-arousal |
43
| **Emotional Regulation** | mood regulation, rumination, trauma-related dysregulation |
44
| **Executive Function** | working memory, planning, inhibitory control |
45
| **Motor / Performance Readiness** | precision execution, flow, reaction readiness |
46
| **Sleep / Recovery** | winding down, sleep readiness, recovery |
47
| **Fatigue Resistance** | maintaining function under prolonged load |
48
49
If the client has multiple goals, choose **one primary goal**.
50
51
### If the client has no clear goal
52
Use the battery to infer a **ranked shortlist of candidate axis families**.
53
54
Logic:
55
56
**battery performance -> bottleneck profile -> candidate axis family -> short probe protocol -> validate**
57
58
Examples:
59
- strong drift / RT variability -> **Task Engagement / Calm Focus**
60
- collapse under pressure -> **Arousal Regulation**
61
- poor dual-task / n-back performance -> **Executive Recruitment / Cognitive Control**
62
- poor downshifting after challenge -> **Affective Regulation / Sleep Readiness**
63
64

65
66
## 2. Check Constraints
67
68
Before choosing a protocol, screen for:
69
70
- age / developmental stage
71
- diagnoses
72
- medication effects
73
- sleep / fatigue load
74
- sensory sensitivities
75
- stimulation tolerance
76
- EEG / fNIRS / wearable suitability
77
- whether basic behavioral regulation is needed first
78
79
This prevents bad target selection and modality mismatch.
80
81
---
82
83
## 3. Run a Personalization Battery
84
85
The battery is used to see **how the client functions across conditions**, not to diagnose them from signals alone.
86
87
### Battery structure
88
- **Baseline:** rest, simple breathing, low-demand baseline
89
- **Easy task:** low-demand task relevant to the domain
90
- **Challenge / load:** harder task, distraction, pressure, fatigue, conflict, emotional load
91
- **Recovery:** down-regulation or reset block
92
- **Goal-specific block:** a task close to the real-world target
93
94
### Battery design note
95
This should be a **shared scaffold**, not one identical task set for every client.
96
97
Use the same overall structure across domains, but adapt the task content:
98
99
- **sport / performance:** pressure, motor execution, fatigue, competition simulation
100
- **wellbeing / human performance:** sustained attention, working memory, distraction, cognitive fatigue
101
- **clinical:** symptom-relevant challenge, emotional provocation, recovery capacity, safety-aware tasks
102
103
### What the battery should produce
104
- **Baseline profile**
105
- **Challenge profile**
106
- **Recovery profile**
107
- **Goal-relevant profile**
108
- **Signal reliability profile**
109

111
112
## 4. Select the Target Axes
113
114
Do **not** jump straight to a marker.
115
116
First choose the construct axes that best explain the client’s bottleneck.
117
118
### Recommended canonical axes
119
120
| Axis | What It Represents |
121
|---|---|
122
| **Arousal / Activation** | under-activated vs optimal vs over-activated |
123
| **Task Engagement** | on-task vs drifting |
124
| **Cognitive Control** | top-down effortful control and monitoring |
125
| **Calm Focus** | stable, low-noise attentional readiness |
126
| **Affective Regulation** | emotional load and regulation success |
127
| **Executive Recruitment** | working-memory / prefrontal engagement |
128
| **Fatigue / Instability** | drift and degradation over time |
129
| **Sleep Readiness / Recovery** | winding down and sleep-supportive regulation |
130
| **Motor Automaticity** | reduced overthinking, fluid execution |
131
| **Perceptual Breadth** | scanning and situational awareness |
132
133
### Default rule
134
Choose:
135
- **1 primary axis**
136
- **1 secondary axis**
137
- **optional 1 constraint axis**
138
139
Example:
140
- primary = **Arousal Regulation**
141
- secondary = **Calm Focus**
142
- constraint = **Fatigue**
143
144
---
145
146
## 5. Translate Axes Into Target States
147
148
States are the specific conditions the protocol wants to train.
149
150
They should be:
151
- meaningful
152
- measurable
153
- trainable
154
- linked to outcomes
155
156
### Examples
157
158
| Client Type | Example Target States | Desired Transition |
159
|---|---|---|
160
| **Attention** | distracted, effortful, stable attention, fatigued | **distracted -> stable attention** |
161
| **Anxiety / stress** | under-activated, optimal, over-aroused, dysregulated | **over-aroused -> optimal** |
162
| **Executive function** | under-recruited, optimal, overloaded | **under-recruited / overloaded -> optimal** |
163
| **Sleep / recovery** | alert, winding down, sleep-ready, restless | **restless -> sleep-ready** |
164
| **Athletic precision** | under-engaged, calm-focused, over-controlled, over-aroused, competition-ready | **over-controlled / over-aroused -> competition-ready** |
165
166
---
167
168
## 6. Choose the Modality
169
170
Only after the axes and states are defined should the system choose the modality.
171
172
### Typical fit
173
174
| Situation | Likely Better Modality |
175
|---|---|
176
| fast oscillatory attention / arousal training | **EEG** |
177
| executive load / cognitive control | **fNIRS** or **EEG + task coupling** |
178
| movement-tolerant cognitive training | **fNIRS** |
179
| simple home use | **wearable EEG** or **wearable stimulation** |
180
| sleep / recovery | **auditory** or **wearable regulation** |
181
| precision low-noise training | **EEG** |
182
| immersive real-world tasks | **EEG / fNIRS + VR or task integration** |
183
184
Choose based on:
185
- target axis
186
- context
187
- motion tolerance
188
- signal quality
189
- user burden
190
- commercial feasibility
191
192

193
194
## 7. Select Markers and Direction
195
196
Only now should the system choose markers.
197
198
Markers are chosen because they are the best handles for the selected axis and state transition.
199
200
### Examples
201
202
| Target Axis | Possible Marker Families |
203
|---|---|
204
| **Calm Focus** | SMR, Upper Alpha, Theta/Beta, tension markers |
205
| **Affective Regulation** | FAA, Alpha/Theta, decoded emotion-state patterns |
206
| **Executive Recruitment** | FMT, dlPFC HbO, decoded fNIRS patterns |
207
| **Motor Automaticity** | T3 Alpha, Temporal-Frontal Coherence |
208
209
### Directionality rule
210
Do not assume “up is always good.”
211
212
Possible directions:
213
- increase
214
- decrease
215
- stabilize
216
- keep within optimal band
217
- minimize distance to best-state region
218
219
---
220
221
## 8. Generate the Prescription
222
223
The system should output a **prescription object** containing:
224
225
- primary goal
226
- primary axis
227
- secondary axis
228
- target state transition
229
- chosen modality
230
- chosen markers
231
- target direction
232
- session context
233
- feedback style
234
- recommended dose
235
- transfer measure
236
- responder confidence
237
- review point
238
- stop / adapt criteria
239
240
### Example
241
**Goal:** reduce pressure-induced attentional collapse
242
**Primary axis:** Arousal Regulation
243
**Secondary axis:** Calm Focus
244
**Target transition:** over-aroused -> optimal
245
**Modality:** EEG neurofeedback during task
246
**Markers:** SMR + stress marker
247
**Direction:** increase calm-focus composite, reduce hyperarousal
248
**Review:** re-check after 3 sessions using pressure-task performance and state stability
249
250
---
251
252
## 9. Use an Early Response Check
253
254
Do not assume the first protocol is correct.
255
256
Check early:
257
- can the client modulate the target?
258
- does the state move in the right direction?
259
- is there behavioral transfer?
260
- is the protocol too effortful?
261
- is the signal too noisy?
262
- would a different modality fit better?
263
264
### Possible outcomes
265
- likely responder
266
- responder but needs adaptation
267
- unclear
268
- wrong target
269
- wrong modality
270
- non-responder to current protocol
271
272
This allows:
273
- continue
274
- simplify
275
- escalate
276
- switch
277
- stop
278

## Design Rule
299
300
Do **not** build a decision system that says:
301
- poor focus -> theta/beta
302
- anxiety -> FAA
303
- sleep issue -> alpha/theta
304
305
Build a system that says:
306
307
**this client, with this goal, under these constraints, appears to need these axes targeted, with this state transition, via this modality, using these markers, in this direction, with this review rule**
308
309

310
311
## Summary
312
313
A personalized neurofeedback / neuromodulation pipeline should:
314
315
1. start with the client’s goal
316
2. run a structured battery
317
3. identify the key construct axes
318
4. define the target state transition
319
5. choose the best modality
320
6. choose the marker set and direction
321
7. generate a prescription
322
8. check early whether it is working
323
324
**Core abstraction:**
325
**goal -> battery -> axes -> states -> modality -> markers -> prescription -> review**
