Neural substrates underlying the expectation of rewards resulting from effortful exertion

Kavli Affiliate: Vikram Chib | Authors: Aram Kim and Vikram S. Chib | Summary: Expectations as a reference point shape our decisions to motivate effortful activity. Despite the important role of reference points in human performance, little is known about how the brain processes expectations to guide motivated exertion. Participants completed a reward-based effort task […]

A spatial model of autophosphorylation of CaMKII in a glutamatergic spine suggests a network-driven kinetic mechanism for bistable changes in synaptic strength

Kavli Affiliate: Terrence Sejnowski | Authors: Thomas M Bartol, Mariam Ordyan, Terrence J Sejnowski, Padmini Rangamani and Mary B. Kennedy | Summary: Activation of N-methyl-D-aspartate-type glutamate receptors (NMDARs) at synapses in the CNS triggers changes in synaptic strength that underlie memory formation in response to strong synaptic stimuli. The primary target of Ca2+ flowing through […]

Cilia-mediated cerebrospinal fluid flow modulates neuronal and astroglial activity in the zebrafish larval brain

Kavli Affiliate: Emre Yaksi | Authors: Percival P D’Gama, Inyoung Jeong, Andreas Moe Nygard, Ahmed Jamali, Emre Yaksi and Nathalie Jurisch-Yaksi | Summary: The brain uses a specialized system to transport cerebrospinal fluid (CSF). This system consists of interconnected ventricles lined by ependymal cells, which generate a directional flow upon beating of their motile cilia. […]

Evolutionary conservation of mechanical strain distributions in functional transitions of protein structures

Kavli Affiliate: Stanislas Leibler | Authors: Pablo Sartori and Stanislas Leibler | Summary: One of the tenets of molecular biology is that dynamical transitions between three dimensional structures largely determine the function of individual proteins, as well as multi-protein assemblies. Therefore, it seems only natural that evolutionary analysis of proteins, presently based mainly on their […]

When no answer is better than a wrong answer: a causal perspective on batch effects

Kavli Affiliate: Brian Caffo Joshua Vogelstein | Authors: Eric W. Bridgeford, Michael Powell, Gregory Kiar, Stephanie Noble, Jaewon Chung, Sambit Panda, Ross Lawrence, Ting Xu, Michael Milham, Brian Caffo and Joshua T. Vogelstein | Summary: Abstract Batch effects, undesirable sources of variability across multiple experiments, present significant challenges for scientific and clinical discoveries. Batch effects […]

Multiplexing of temporal and spatial information in the lateral entorhinal cortex

Kavli Affiliate: James Knierim | Authors: Cheng Wang, Heekyung Lee, Geeta Rao and James J Knierim | Summary: Abstract Episodic memory involves the processing of spatial and temporal aspects of personal experiences. The lateral entorhinal cortex (LEC) plays an essential role in subserving memory. However, the specific mechanism by which LEC integrates spatial and temporal […]

Incorporation of a cost of deliberation time in perceptual decision making

Kavli Affiliate: Michael Shadlen | Authors: Shinichiro Kira, Ariel Zylberberg and Michael N Shadlen | Summary: Abstract Many decisions benefit from the accumulation of evidence obtained sequentially over time. In such circumstances, the decision maker must balance speed against accuracy, and the nature of this tradeoff mediates competing desiderata and costs, especially those associated with […]
