The population doctrine in cognitive neuroscience
A major shift is happening within neurophysiology: a population doctrine is drawing level
with the single-neuron doctrine that has long dominated the field. Population-level ideas …

The whole prefrontal cortex is premotor cortex
We propose that the entirety of the prefrontal cortex (PFC) can be seen as fundamentally
premotor in nature. By this, we mean that the PFC consists of an action abstraction hierarchy …

Closed-loop enhancement and neural decoding of cognitive control in humans
Deficits in cognitive control—that is, in the ability to withhold a default pre-potent response in
favour of a more adaptive choice—are common in depression, anxiety, addiction and other …

Computational validity: using computation to translate behaviours across species
We propose a new conceptual framework (computational validity) for translation across
species and populations based on the computational similarity between the information …

Continuous decisions
Humans and other animals evolved to make decisions that extend over time with continuous
and ever-changing options. Nonetheless, the academic study of decision-making is mostly …

Semi-orthogonal subspaces for value mediate a binding and generalization trade-off
When choosing between options, we must associate their values with the actions needed to
select them. We hypothesize that the brain solves this binding problem through neural …
