antibiotic and drug-name context

What this neuron does

This neuron is active in medical text about antibiotics and bacteria, such as 'Ampicillin is a penicillin antibiotic'. It works against the word 'form', and it goes quiet or negative right before 'isoform' or 'form'. Turning it up made the model write unrelated sentences and turning it down made it repeat 'form'.

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

   extended-spectrum beta-lactamase with additional resistance to carbenicillin, amoxicillin, and increasingly to ceftazidime. The bacteria remain

2. #2 peak

   in northern Puerto Rico. Particular attention is given to chlorinated volatile organic compounds and phthalates, although biomarkers of phenols, metals, and parabens exposure are also being explored as precursors of preterm birth. Identification of

3. #3 peak

   floxacin is an antibiotic that is part of the fluoroquinolone family. It effectively kills bacteria, while dexameth

4. #4 peak

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.

1. #1 peak

   no overlap between the two diseases, the researchers noted.⏎One chaperone that protected against ALS aggregates — DNAJB14 — exists in two versions, called isoforms. The isoforms are similar, but one is shorter and lacks some important

2. #2 peak

4. #4 peak

   While there are less severe and later-onset versions of citrullinemia type I, the mutations for which Counsyl screens are associated with the more severe form that affects infants shortly after birth. It is also known as “classic”

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.
