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 […]

Spike transmission failures in axons from mouse cortical pyramidal neurons in vivo

Kavli Affiliate: Rafael Yuste | Authors: Netanel Ofer, Victor Hugo Cornejo and Rafael Yuste | Summary: Abstract The propagation of action potentials along axons is traditionally considered to be reliable, as a consequence of the high safety factor of action potential propagation. However, numerical simulations have suggested that, at high frequencies, spikes could fail to […]

The combination of feedforward and feedback processing accounts for contextual effects in visual cortex

Kavli Affiliate: Kenneth Miller | Authors: Serena Di Santo, Mario Dipoppa, Andreas Keller, Morgane Roth, Massimo Scanziani and Kenneth D Miller | Summary: Abstract Sensory systems must combine local features with context to infer meaning. Accordingly, context profoundly influences neural responses. We developed a unified circuit model demonstrating how feedforward and feedback inputs are integrated […]

Value construction through sequential sampling explains serial dependencies in decision making

Kavli Affiliate: Daphna Shohamy and Michael Shadlen | Authors: Ariel Zylberberg, Akram Bakkour, Daphna Shohamy and Michael N Shadlen | Summary: Many decisions are expressed as a preference for one item over another. When these items are familiar, it is often assumed that the decision maker assigns a value to each of the items and […]

Effects of parental age and polymer composition on short tandem repeat de novo mutation rates

Kavli Affiliate: Michael Goldberg | Authors: Michael E Goldberg, Michelle D Noyes, Evan E Eichler, Aaron Quinlan and Kelley Harris | Summary: Short tandem repeats (STRs) are hotspots of genomic variability in the human germline because of their high mutation rates, which have long been attributed largely to polymerase slippage during DNA replication. This model […]

Circuit-motivated generalized affine models characterize stimulus-dependent visual cortical shared variability

Kavli Affiliate: Kenneth Miller | Authors: Ji Xia, Anna Jasper, Adam Kohn and Kenneth D Miller | Summary: Correlated variability in the visual cortex is modulated by stimulus properties. The stimulus dependence of correlated variability impacts stimulus coding and is indicative of circuit structure. An affine model combining a factor proportional to mean stimulus response […]
