Journal ArticleDOI

Kynurenines in the mammalian brain: when physiology meets pathology

TL;DR: With recently developed pharmacological agents, it is now possible to restore metabolic equilibrium and envisage novel therapeutic interventions on the basis of the kynurenine pathway.
Journal ArticleDOI

The cognitive neuroscience of sustained attention: where top-down meets bottom-up.

TL;DR: The findings from human and animal studies provide the basis for a relatively precise description of the neuronal circuits mediating sustained attention, and the dissociation between these circuits and those mediating the 'arousal' components of attention.
Journal ArticleDOI

Cognitive functions of cortical acetylcholine: toward a unifying hypothesis

TL;DR: While the proposed hypothesis implies that changes in activity in cortical ACh simultaneously occur throughout the cortex, the selectivity and precision of the functions of cholinergic function is due to its coordinated interactions with the activity of converging sensory or associational inputs.
Journal ArticleDOI

Unraveling the attentional functions of cortical cholinergic inputs: interactions between signal-driven and cognitive modulation of signal detection.

TL;DR: This hypothesis begins to explain signal intensity or duration-dependent performance in attention tasks, the distinct effects of cortex-wide versus prefrontal cholinergic deafferentation on attention performance, and it generates specific predictions concerning cortical acetylcholine (ACh) release in attention task-performing animals.
Journal ArticleDOI

Cortical cholinergic inputs mediating arousal, attentional processing and dreaming: differential afferent regulation of the basal forebrain by telencephalic and brainstem afferents.

TL;DR: Long-standing speculations about the similarities between dreaming and psychotic cognition are substantiated by describing the role of an over(re)active cortical cholinergic input system in either condition.
