BULL / BEAR β€” competing evidence-accumulation pools, coupled by shared inhibitory relays (inh_bull / inh_bear) that make the competition winner-take-all, as in LIP.

DANGER — the amygdala→STN stop pathway: strong inhibition onto BULL; raises the bar for GO and vetoes entries.

sensory neurons
Opponent-coded market features: each family drives an ON channel (evidence for) and an OFF channel (evidence against), the way direction-selective MT/V5 columns code opposing motion. Missing data drives nothing β€” absence is never evidence.
reciprocal inhibition
BULL and BEAR excite shared inhibitory relays (INH) of fast-spiking PV+ interneurons, which inhibit the opposite pool β€” the winner-take-all competition that settles LIP evidence accumulation. Self-excitation gives the winner persistence; brief blips can’t flip the state.
danger pathway
Rug indicators, liquidity collapse, contract permissions and concentration excite DANGER, which projects strong inhibition onto BULL β€” modeled on the amygdala threat signal driving the hyperdirect (STN) stop pathway. High danger also hard-vetoes entries in the strategy layer.
