Working memory is the fundamental function by which we break free from reflexive input-
output reactions to gain control over our own thoughts. It has two types of mechanisms …

Attention is the important ability to flexibly control limited computational resources. It has
been studied in conjunction with many other topics in neuroscience and psychology …

I propose that synchronization affects communication between neuronal groups. Gamma-
band (30–90 Hz) synchronization modulates excitation rapidly enough that it escapes the …

Persistent spiking has been thought to underlie working memory (WM). However, virtually all
of the evidence for this comes from studies that averaged spiking across time and across …

Cognitive functions rely on the coordinated activity of neurons in many brain regions, but the
interactions between cortical areas are not yet well understood. Here we investigated …

Re-entrant or feedback pathways between cortical areas carry rich and varied information
about behavioural context, including attention, expectation, perceptual tasks, working …

The brain has a limited capacity and therefore needs mechanisms to selectively enhance
the information most relevant to one's current behavior. We refer to these mechanisms as" …

A free-energy principle has been proposed recently that accounts for action, perception and
learning. This Review looks at some key brain theories in the biological (for example, neural …

This paper considers communication in terms of inference about the behaviour of others
(and our own behaviour). It is based on the premise that our sensations are largely …

Decreases in alpha synchronization are correlated with enhanced attention, whereas alpha
increases are correlated with inattention. However, correlation is not causality, and …
