TLDR
It is proposed that the occurrence of LVFA in the neocortex is determined by two distinct reticulocortical systems and a cholinergic system produces all LVFA occurring during Type II behavior and a second system, dependent on a monoamine, produces LV FA in association with Type I behavior.Citations

Cortical state and attention
TL;DR: It is suggested that selective attention involves processes that are similar to state change, and that operate at a local columnar level to enhance the representation of otherwise non-salient features while suppressing internally generated activity patterns.

Neuromodulation of Brain States
Seung-Hee Lee,Yang Dan +1 more
TL;DR: Current understanding of the key neural circuits involved in regulating brain states, with a particular emphasis on the subcortical neuromodulatory systems are summarized.

Cerebral Activity and Behavior: Control by Central Cholinergic and Serotonergic Systems
TL;DR: This chapter presents the genesis of the electrocorticogram to provide a basis for understanding the nature of cortical activation and discusses new evidence showing that cortical activation is dependent on both cholinergic and serotonergic inputs to the neocortex.
Journal ArticleDOI
Reticulo-cortical activity and behavior: A critique of the arousal theory and a new synthesis
TL;DR: The fact that patterns characteristic of sleep, arousal, and waking behavior continue in decorticate animals indicates that reticulo-cortical mechanisms are not essential for these aspects of behavior.
Journal ArticleDOI
Evidence that serotonin mediates non-cholinergic neocortical low voltage fast activity, non-cholinergic hippocampal rhythmical slow activity and contributes to intelligent behavior
TL;DR: The role of 5-hydroxytryptamine (5-HT) in this pathway was studied in rats treated with p-chlorophenylalanine and a combination of PCPA and atropine produced a very severe deficit in performance in a simple water maze.

Rapid method for the determination of 5-hydroxytryptamine and 5-hydroxyindoleacetic acid in small regions of rat brain
G. Curzon,A. R. Green +1 more
TL;DR: A rapid and sensitive method for measuring 5‐hydroxytryptamine and 5-hydroxyindoleacetic acid, using o‐phthalaldehyde and L‐cysteine, is presented, enabling both compounds to be measured in small areas of rat brain.

A method for the determination of serotonin and norepinephrine in discrete areas of rat brain.
TL;DR: A method for the determination of both serotonin (5HT) and norepinephrine (NE) in small samples of brain is described, applicable to as little as 50 mg of brain tissue.
