Comparisons are fundamental to science: experiment against model, one organism against another, a system against itself across time. Because many systems, from brains to climate, are characterized by ...

Dorsal and ventral noradrenergic neurons in the locus coeruleus form topographic subpopulations whose projection patterns and activity encode choice switching, reward-prediction errors and disregard o...

The Life Sciences Departments in Harvard Faculty of Arts and Sciences seek to recruit a tenure-track professor whose research is at the interface of AI and life sciences, from methodological developme...

Detecting a target odor against complex backgrounds requires separating signal from interference. McCalmon et al. show that discrimination performance depends on target odor concentration but not back...

Growing evidence shows that dopamine signaling is diverse, with dopaminergic neurons responding to rewarding and aversive stimuli. Here, we hypothesiz…

Individual midbrain dopamine (mDA) neurons exhibit complex morphologies, a feature that may underlie their different functions and disease vulnerabili…

Animals navigate odor plumes by exploiting dynamic and intermittent cues. Here, the authors show that mice can discriminate among different fluctuating odor signals, and characterize their neural enco...

Learning is thought to arise from synaptic modifications embedded in brain-wide circuits, yet how such circuits coordinate plasticity to support complex behaviour is not known. Inspired by deep learni...

Why do we want to know the future? Humans and many animals pay for information to predict uncertain rewards, even when they cannot control them. The reason for this conserved yet seemingly paradoxical...

Animals navigate odor plumes by exploiting dynamic and intermittent cues. Here, the authors show that mice can discriminate among different fluctuating odor signals, and characterize their neural enco...

Nature Neuroscience - Jang et al. measured dopamine and acetylcholine release in the striatum of rats performing a decision-making task and found that the relative timing of cholinergic and...

Large-scale autoregressive models pretrained on next-token prediction and finetuned with reinforcement learning (RL) have achieved unprecedented success on many problem domains. During RL, these model...

No two neurons are the same, yet models often treat neural populations as pools of identical and interchangeable elements. Here, Dahmen et al. highlight recent theoretical advances that reveal the imp...
