Qwen3-0.6B

numbness, pain and nerve symptoms

A neuron in layer 20 of Qwen3-0.6B. Its strongest snippets are mixed: they peak on different tokens. It is featured, so it has steering outputs.

What this neuron does

This neuron fires on medical words that describe nerve problems, such as 'numbness', 'pain' and 'sensory' in descriptions of symptoms and nerves. Turning it up or down did not produce anything medical, so the steering results do not confirm this.

Written by Claude from this neuron's activations and steering outputs. Confidence: medium. Think it is wrong? Flag it (opens a prefilled issue on GitHub).

Fires most on

The text windows where this neuron's activation was highest. Amber marks positive activation; the outlined token is the peak. Hover a token for its strength.

  1. #1 peak

    hip to the sole of the foot.⏎The main task of the sciatic nerve, one of the most important nerves of the body, is to send signals to the fibers that provide the strength and movement of the leg

  2. #2 peak

    pain, which can also be observed with symptoms such as numbness and tingling in the legs and feet, may cause loss of strength in the muscles it stimulates,

  3. #3 peak

    and symptoms include:⏎Trouble talking and understanding what others are saying. You may get upset, talk blurred or have trouble understanding speech.⏎Paralysis or numbness of the face, arm, or leg may occur. You may have sudden numbness

  4. #4 peak

    adicus in the medical language, starts from the waist and continues to the heel and is the longest and widest nerve known. The sciatic nerve creates motor and sensory functions in the

  5. #5 peak

    not a killer.⏎But this chronic inflammatory autoimmune disease of the central nervous system severely damages the communication between nerve cells in the brain and the spinal cord– leading to pain and debilitation. In essence, a protective sheath called myelin is attacked

  6. #6 peak

    atica pain, which increases with movement, can cause difficulties especially when sitting and moving from sitting to standing position.⏎In advanced stages, sciatic pain can lead to numbness and difficulty in movement, along with pain in the areas where it is located

Steering

Push this neuron up or down while the model writes, and watch what changes. The outputs were generated ahead of time, so nothing runs in your browser.

Here is something I have been thinking about lately: on the surface, it seems to be a simple problem, but when we need to find the total of the series at an arbitrary number of nodes, we have to at least make a log log log log log... log log log log...

Most negative on

Where the activation went furthest below zero. Blue marks negative activation. Many neurons mean something different in each direction.

    becomes dry and itchy and is most common on the inside of elbows, behind the knees, neck, head and scalp and the buttocks.⏎It is caused by:⏎- Food such as cow’s milk, citrus, wheat, eggs, and

  2. #2 peak

    gingivitis, which is the only reversible stage of the disease. This causes gum inflammation, pain while chewing, or bleeding and swollen gums. This is caused by plaque on the teeth. However, if gum disease is diagnosed early on, Dr

  4. #4 peak

    a role in flares and disease control. The bacteria and human genetics are thought to be linked in part by the impaired skin barrier function (e.g. control of water loss, acidity, etc) that results in an altered environment for the bacteria

How often this neuron fires at each strength. Almost always it does close to nothing (the tall bars in the middle); the snippets above are the rare moments it fired hard, amber for positive and blue for negative.
