RESPAN: A Deep Learning Pipeline for Accurate and Automated Restoration, Segmentation, and Quantification of Dendritic Spines

Kavli Affiliate: Franck Polleux | Authors: Sergio B. Garcia, Alexa P. Schlotter, Daniela Pereira, Aleksandra J Recupero, Franck Polleux and Luke A Hammond | Summary: Quantification of dendritic spines is essential for studying synaptic connectivity, yet most current approaches require manual adjustments or the combination of multiple software tools for optimal results. Here, we present […]

Circuit-Based Understanding of Fine Spatial Scale Clustering of Orientation Tuning in Mouse Visual Cortex

Kavli Affiliate: Kenneth Miller | Authors: Peijia Yu, Yuhan Yang, Olivia Gozel, Ian Oldenburg, Mario Dipoppa, Federico Rossi, Kenneth Miller, Hillel Adesnik, Na Ji and Brent Doiron | Summary: In sensory cortex of brain it is often the case that neurons are spatially organized by their functional properties. A hallmark of primary visual cortex (V1) […]

Rarely categorical, always high-dimensional: how the neural code changes along the cortical hierarchy

Kavli Affiliate: Stefano Fusi | Authors: Lorenzo Posani, Shuqi Wang, Samuel Muscinelli, Liam Paninski and Stefano Fusi | Summary: A long-standing debate in neuroscience concerns whether individual neurons are organized into functionally distinct populations that encode information differently (“categorical” representations [1–3]) and the implications for neural computation. Here, we systematically analyzed how cortical neurons encode […]

Neuronal Silencing and Protection in a Mouse Model of Demyelination

Kavli Affiliate: Aniruddha Das | Authors: Aniruddha Das, Julie Borovicka, Hale Tobin, Shruti Bhatia, Jacob Icardi, Ghazaal Tahmasebi, Priyanka Agochiya, Shriya Singh, Bruce Trapp and Hod Dana | Summary: Damage to the myelin sheath that protects axons in the central nervous system is a hallmark pathology of demyelinating diseases like multiple sclerosis. Cuprizone-induced demyelination in […]

Population Representation of the Confidence in a Decision in the Parietal Cortex

Kavli Affiliate: Michael Shadlen | Authors: Ariel Zylberberg and Michael N Shadlen | Summary: Confidence in a decision is the belief, prior to feedback, that one’s choice is correct. In the brain, many decisions are implemented as a race between competing evidence-accumulation processes. We ask whether the neurons that represent evidence accumulation also carry information […]

The geometry of the neural state space of decisions

Kavli Affiliate: Kenneth Miller | Authors: Mauro M. Monsalve-Mercado and Kenneth D Miller | Summary: How do populations of neurons collectively encode and process information during cognitive tasks? We analyze high-yield population recordings from the macaque lateral intraparietal area (LIP) during a reaction-time random-dot-motion direction-discrimination task. We find that the trajectories of neural population activity […]

The effects of task similarity during representation learning in brains and neural networks

Kavli Affiliate: Stefano Fusi | Authors: Nicholas Menghi, William Jeffrey Johnston, Simone Vigano’, Max Andreas Bosse Hinrichs, Burkhard Maess, Stefano Fusi and Christian F Doeller | Summary: The complexity of our environment poses significant challenges for adaptive behavior. Recognizing shared structures across tasks can theoretically improve learning through generalization. However, how such shared representations emerge […]

Experience-dependent reorganization of inhibitory neuron synaptic connectivity

Kavli Affiliate: Richard Axel | Authors: Andrew Jacob Pixley Fink, Samuel Muscinelli, Shuqi Wang, Marcus I Hogan, Daniel Fine English, Richard Axel, Ashok Litwin-Kumar and Carl E. Schoonover | Summary: Organisms continually tune their perceptual systems to the features they encounter in their environment1–3. We have studied how ongoing experience reorganizes the synaptic connectivity of […]

Distinct roles of cortical layer 5 subtypes in associative learning

Kavli Affiliate: Rui Costa | Authors: Sara Moberg, Michele Garibbo, Camille Mazo, Ariel Gilad, Dietmar Schmitz, Rui Ponte Costa, Matthew E Larkum and Naoya Takahashi | Summary: Adaptive behavior is critically dependent on associative learning, where environmental cues are linked with subsequent positive or negative outcomes. In mammals, primary neocortical sensory areas serve as pivotal […]
