Multi-timescale learning signals in Drosophila dopaminergic neurons

Kavli Affiliate: Dhruv Grover | Authors: Woochan Choi, Shyam Srinivasan and Dhruv Grover | Summary: Learning often requires inference over hidden task structure, including features that predict outcomes. In mammals, prediction-error signaling by midbrain dopamine neurons is considered central to learning, but how these neurons reflect the progression and stability of learning remains unclear. Using […]

Intensity-dependent topographical expansion of sensory representations

Kavli Affiliate: Martin Lindquist | Authors: Li-Bo Zhang, Amin Dehghani, Li Hu, Patrick Sadil, Liz Losin, Martin Lindquist and Tor Wager | Summary: Neuroimaging studies typically assume that sensory properties are encoded in response magnitude within fixed neural populations. However, this approach does not capture changes in the spatial extent of activation topography, despite growing […]

Eosinophil-epithelial interactions mediate protective intestinal remodeling during food allergy

Kavli Affiliate: Daniel Mucida | Authors: Patrick W Darcy, Vitoria M Olyntho, Albana Kodra, Zachary Kerner, Maria C.C. Canesso, Sandra Nakandakari-Higa, Gabriel Victora and Daniel Mucida | Summary: Food allergies are associated with progressive gastrointestinal symptoms driven by exacerbated mucosal type-2 immunity. Here, we investigated whether cellular interactions between the gut epithelium and innate immune […]

Connectivity Logic of Dendritic Spines in Cortex: Increased Inputs and Ensemble Formation

Kavli Affiliate: Rafael Yuste | Authors: Dean Geckt, Netanel Ofer, Michael W. Reimann, Rafael Yuste and Idan Segev | Summary: Dendritic spines, small protrusions covering the dendrites of most neurons, are fundamental elements of synaptic connectivity, yet their network-level organization remains poorly understood. Here we leverage the large-scale MICrONS volumetric electron microscopy dataset of mouse […]

Social Novelty Recruits a Dysfunctional Nucleus Accumbens Ensemble That Drives Social Avoidance in a Shank3-/- Autism Model

Kavli Affiliate: Marina Picciotto | Authors: Oakleigh M Folkes, Meaghan Donahue, Rafael E Perez, Angélica Minier-Toribio, Paola N. Negrón-Moreno, Marina R. Picciotto and Yong-Hui Jiang | Summary: Social behavior deficits are a common symptom of neuropsychiatric disorders, including autism spectrum disorder (ASD), but there are limited pharmacological treatments for these symptoms. Understanding how neurons encode […]

Flexible route planning and rapid structure learning by mice in complex environments

Kavli Affiliate: Rui Costa | Authors: Michael Pereira, Beatriz S. Godinho, Christian K. Machens, Rui M. Costa and Thomas Akam | Summary: Action selection using predictive models of the environment plays a fundamental role in human and animal behaviour, yet is poorly understood at circuit and algorithmic levels. Spatial navigation is an attractive domain for […]
