The last ten years of attention research have witnessed a revolution, replacing a theoretical
dichotomy (top-down vs. bottom-up control) with a trichotomy (biased by current goals …

What mechanisms underlie flexible inter-areal communication in the cortex? We consider
four mechanisms for temporal coordination and their contributions to communication:(1) …

Cognitive control guides behaviour by controlling what, when, and how information is
represented in the brain. For example, attention controls sensory processing; top-down …

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

How is it that thoroughly physical material beings such as ourselves can think, dream, feel,
create and understand ideas, theories and concepts? How does mere matter give rise to all …

Cortical gain regulation allows neurons to respond adaptively to changing inputs. Neural
gain is modulated by internal and external influences, including attentional and arousal …

The state of the brain and body constantly varies on rapid and slow timescales. These
variations contribute to the apparent noisiness of sensory responses at both the neural and …

Attention is critical to high-level cognition and attention deficits are a hallmark of neurologic
and neuropsychiatric disorders. Although years of research indicates that distinct …

Visual attention enables us to selectively prioritize or suppress information in the
environment. Prominent models concerned with the control of visual attention differentiate …

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