The paper uses ethograms to show that a fear conditioned visual cue in rats suppresses reward seeking and elicits freezing, with classification accuracy improved by full ethogram data.

This study investigates how rats time their defensive behavior in response to fear conditioning cues, showing maximal suppression before shock delivery.

The paper identifies distinct threat and valence signaling in the rat nucleus accumbens core through single-unit activity recordings during fear discrimination tasks.

The paper shows that two VP neuron populations signal relative threat by decreasing firing with increasing shock probability, with one also signaling reward value.
