Decoding and perturbing decision states in real time

The paper decodes real-time decision variables from motor cortex activity and shows their link to choice behavior and decision dynamics.

Differential encoding in prefrontal cortex projection neuron classes across cognitive tasks

The paper examines how transcriptomic types of mouse prefrontal cortex projection neurons relate to axonal projections and encoding properties across cognitive tasks, finding redundant but quantitatively biased task signal encoding.

Macaque dorsal premotor cortex exhibits decision-related activity only when specific stimulus-response associations are known

The paper shows that decision-related activity in macaque PMd is linked to action selection, not perceptual processing, when specific stimulus-response associations are known.

Brittleness in model selection analysis of single neuron firing rates

The paper shows that model selection in neural data can be unreliable due to brittleness, where small data changes affect model rankings, and suggests ways to address this issue.

Population dynamics of choice representation in dorsal premotor and primary motor cortex

This study examines how decision variables are represented in neural populations of PMd and M1 during a motor task, showing differences in timing and strength between areas and replicating findings with a computational model.
