Fast-spiking neurons in monkey orbitofrontal cortex underlie economic value computation

The paper shows that fast-spiking neurons in monkey orbitofrontal cortex compute economic value more strongly than regular-spiking neurons due to their wider dynamic range.

Degenerate oligonucleotide primer MIG-seq: an effective PCR-based method for high-throughput genotyping

The paper introduces dpMIG-seq, a PCR-based method for high-throughput genotyping that improves polymorphism discovery in crop species compared to MIG-seq.

Distinct roles of the orbitofrontal cortex, ventral striatum, and dopamine neurons in counterfactual thinking of decision outcomes

This study identifies distinct roles of the orbitofrontal cortex, ventral striatum, and dopamine neurons in processing counterfactual outcomes during decision-making in monkeys.

Cingulate-motor circuits update rule representations for sequential choice decisions

This study shows that cingulate cortex inputs to motor cortex are necessary for updating rule representations during sequential choice decisions after rule switches.

Dynamic prospect theory - two core economic decision theories coexist in the gambling behavior of monkeys

This paper combines prospect theory and reinforcement learning to model gambling behavior in monkeys, finding that probability weighting changes dynamically with reward prediction error.
