Key Points

Neural population dynamics form a continuous line attractor that directly encodes an affective state, establishing a causal neural substrate for emotion.
Continuous attractors, previously established for head direction and eye position, are causally linked to continuous internal representations of affect.
These findings demonstrate that continuous attractors underlie affective states, providing mechanistic insight into continuous neural representations.

Implication

Experimental investigation demonstrates line attractor dynamics encoding an affective state, suggesting continuous neural population mechanisms for emotion.

Abstract

Continuous attractors are an emergent property of neural population dynamics that have been hypothesized to encode continuous variables such as head direction and eye position
