A Spectrum of Time Horizons for Dopamine Signals

Kavli Affiliate: Joshua Berke | Authors: Wei Wei, Ali Mohebi and Joshua Berke | Summary: Dopamine input to striatum can encode reward prediction error, a critical signal for updating predictions of future rewards. However, it is unclear how this mechanism handles the need to make predictions, and provide feedback, over multiple time horizons: from seconds […]

Long-range inhibition synchronizes and updates prefrontal task activity

Kavli Affiliate: Vikaas Sohal | Authors: Kathleen Cho, Jingcheng Shi and Vikaas Singh Sohal | Summary: Changes in patterns of activity within the medial prefrontal cortex enable rodents, non-human primates, and humans to update their behavior to adapt to changes in the environment, e.g., during cognitive tasks1–5. Within medial prefrontal cortex, inhibitory neurons expressing parvalbumin […]

Not optimal, just noisy: the geometry of correlated variability leads to highly suboptimal sensory coding

Kavli Affiliate: Kristofer Bouchard | Authors: Jesse A Livezey, Pratik Singh Sachdeva, Maximilian E Dougherty, Mathew T Summers and Kristofer E Bouchard | Summary: The brain represents the world through the activity of neural populations. Correlated variability across simultaneously recorded neurons (noise correlations) has been observed across cortical areas and experimental paradigms. Many studies have […]
