Kavli Affiliate: Vincent Ferrera | Authors: Fabian A Munoz Silva, Greg Jensen, Maxwell Shinn, Yelda Alkan, John Murray, Herbert Terrace and Vincent P Ferrera | Summary: The accumulation of evidence over time formalized in the drift diffusion model (DDM), has become one of the most prevalent models of deliberative decision-making. To better understand the role […]
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 […]
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) […]
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 […]
Kavli Affiliate: Scott Small | Authors: Clara T Rehmann, Scott T Small, Peter L Ralph and Andrew D. Kern | Summary: As organisms adapt to environmental changes, natural selection modifies the frequency of non-neutral alleles. For beneficial mutations, the outcome of this process may be a selective sweep, in which an allele rapidly increases in […]
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 […]
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 […]
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 […]
Kavli Affiliate: Kenneth Miller | Authors: Ho Yin Chau, Kenneth D Miller and Agostina Palmigiano | Summary: What are the principles that govern the responses of cortical networks to their inputs and the emergence of these responses from recurrent connectivity? Recent experiments have probed these questions by measuring cortical responses to two-photon optogenetic perturbations of […]
Kavli Affiliate: Stefano Fusi and Kenneth Miller | Authors: Mario Dipoppa, Ramon Nogueira, Stéphane Bugeon, Yoni Friedman, Charu B. Reddy, Kenneth D. Harris, Dario L. Ringach, Kenneth D. Miller, Matteo Carandini and Stefano Fusi | Summary: Allogeneic stem cell transplant (alloSCT) for patients with relapsed/refractory chronic lymphocytic Sensory adaptation dynamically changes neural responses as a […]
