What this neuron does

This neuron lights up on the word 'and' when it links two matching things, like 'men and women', 'the cathode and the anode', or 'systolic and diastolic'. Turning it up made the model produce long strings of list-like repetition, not a clear theme.

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

   in the Western world at least, men and women do gain weight from the age of 35 onwards, averaging around half a kilo per year for men and a little more for women.⏎The reason is not an aging metabolism. While older

2. #2 peak

   Blood pressure is one of the vital signs of life. It is normally expressed as two numbers, the first or the upper number indicating the systolic blood pressure, and

3. #3 peak

   it is either shifted away by air movement or re-radiated by the glass surface.⏎Typically, a highly reflective material will have a low emissivity, and a dull darker colored material will have a high emissivity. Reducing the emiss

   and regrettable risky behaviors. Once you turn 21, try sticking to the recommended daily limit of no more than two beers or glasses of wine for men and one for women.⏎Kick the bad habits!⏎Rub snuff, smoke cigarettes or

5. #5 peak

   rechargeable batteries that you can use in place of disposables.⏎Instead, you might use nickel-cadmium batteries (NiCd). Nickel is the cathode and cadmium is the anode. The recharge process isn’t perfect though, so

6. #6 peak

   antisense oligonucleotides (ASO) that modulate splicing for PK-M. The cells are visible under light microscopy in the left column, and the DNA in their nuclei shows up when using the blue dye DAPI in the

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.

Most negative on

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

   ampere, but with different meanings. To avoid confusion, the prefix “ab-” was often added to cgs electromagnetic units (especially by Americans) and “stat-” to cgs electrostatic system units. Many workers did not use

Which neurons in earlier layers feed this one, and which later ones it feeds. Amber links excite, blue links suppress; longer bars are stronger.

Activation histogram

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.

Logit lens

The words this neuron nudges the model toward (amber) or away from (blue) when it fires. A hint, not a label: many neurons work through later layers instead.
