Age-related changes in behavioural and neural variability in a decision-making task

|
By Anup Khanal, Sonja Forster, Anne Churchland, Anne E. Urai, Fenying Zang
| Nature Verified
Abstract Age-related cognitive decline in learning and decision-making may arise from increased variability of neural responses. Here, we investigated how ageing affects behavioural and neural variability by recording >18,000 neurons across 16 brain regions (including cortex, hippocampus, thalamus, midbrain, and basal ganglia) in younger and older mice performing a visual decision-making task. Older mice showed more variable response times, reproducing a common finding in human ageing studies.

Anterior cingulate neurons combine outcome monitoring of past decisions with ongoing movement signals

| Nature Verified
Abstract In dynamic environments, animals must closely monitor the effects of their actions to inform switches in behavioral strategy. Anterior cingulate cortex (ACC) neurons track decision outcomes in these environments. Yet, it remains unclear whether ACC neurons similarly monitor behavioral history in static environments and, if so, whether these signals are distinct from movement representations.

Reproducibility is a team sport

|
By Anne Churchland
| The Transmitter Verified
Almost everyone says they care about reproducibility. And sure, lots of folks have heard of and perhaps worried about the replication crisis that has been rattling some areas of science. But when it comes to doing something about it, the crowd gets a lot thinner. Few people roll up their sleeves to tackle the issue head-on, and even fewer pause to wonder if their own methods might be part of the problem. Why is that?
