Composing trajectories for rapid inference of navigational goals

The paper develops an algorithm inspired by mouse behavior to rapidly infer navigational goals through Bayesian inference and trajectory composition.

Sex-specific plasticity mechanisms mediating fear extinction

The paper shows that male and female mice use different synaptic plasticity mechanisms for fear extinction, with males showing structural remodeling and GRIN2B dependence, while females do not.

Mesolimbic dopamine adapts the rate of learning from action

This study shows that mesolimbic dopamine adjusts the rate of learning from action in mice, supporting a model where dopamine signals set an adaptive learning rate rather than serving as an error signal.

Emergence of reward expectation signals in identified dopamine neurons

This study shows that dopamine neuron activity in early learning reflects reward expectation based on sensory and action initiation cues rather than reward prediction errors.
