Lesson: Convergence & Divergence

Divergence & Convergence in the Nervous System

—Why one strike can cause global dysfunction

Convergence

Convergence is when multiple sensory neurons send signals to a single second-order neuron in the spinal cord or brainstem.

Martial Implication:

• Striking a point like LI10 (arm) can affect not just the local area, but also:

• Cervical muscles (via shared spinal levels)

• Autonomic symptoms (like dizziness, due to shared pathways)

• Proximal joints (shoulder dysfunction from a forearm hit)

Convergence explains why a strike to the forearm can create effects in the neck or trigger balance disruption—it’s all linked at the spinal cord.

Divergence

Divergence is when a single sensory neuron branches & sends signals to multiple second-order neurons.

Martial Implication:

• A precise nerve strike (e.g., ST5 or GB20) can cause:

• Local muscular inhibition

• Referred pain

• Disrupted proprioception

• Unstable balance

• Temporary autonomic dysregulation (nausea, seeing stars, etc.)

One well-placed shot has ripple effects because the signal spreads to multiple destinations in the nervous system.

Combine Convergence + Divergence = Maximum Disruption

Kyusho & Tuite are especially effective when they:

• Use a point that converges multiple signals (like a pressure hub)

• Or a strike that diverges its signal broadly, overwhelming coordination, balance, or conscious control.

Think:

• Brainstem-adjacent points (GB20, ST9)

• Sensory-rich locations with shared spinal roots (LI10, TW5, HT6)

Just like point combinations, combining principles takes our effectiveness to a whole other level.
