The Basal Forebrain Corticopetal System Revisited
Annals of the New York Academy of Sciences, 1999ABSTRACT:The medial septum, diagonal bands, ventral pallidum, substantia innominata, globus pallidus, and internal capsule contain a heterogeneous population of neurons, including cholinergic and noncholinergic (mostly GABA containing), corticopetal projection neurons, and interneurons.

Memory impairments following basal forebrain lesions
Brain Research, 1985The functional contribution of the nucleus basalis magnocellularis (NBM) and medial septal area (MSA) to memory was evaluated in 4 behavioral tasks. The tasks were postoperative acquisition of a win-stay spatial discrimination in a T-maze, a win-shift spatial discrimination on a radial arm maze, active avoidance in a shuttle box, and passive avoidance ...

Cognitive functions of the basal forebrain
Current Opinion in Neurobiology, 1999Studies of the function of the basal forebrain have focused on cholinergic neurons that project to cortical and limbic structures critical for various cognitive abilities. Recent experiments suggest that these neurons serve a modulatory function in cognition, by optimizing cortical information processing and influencing attention.

Extended Amygdala and Basal Forebrain
Annals of the New York Academy of Sciences, 2003Abstract: The basal forebrain is a confluence of systems that are crucial to understanding some of the most important functions of the brain, including reward and punishment, learning and cognition, and feeding and reproduction. Basic to understanding this broad spectrum of behavior is untangling the interwoven functional systems in basal forebrain ...

Non-cholinergic basal forebrain neurons project to the contralateral basal forebrain in the rat
Neuroscience Letters, 1988Following injections of wheat germ agglutinin-conjugated horseradish peroxidase (WGA-HRP) or the fluorescent tracer fluoro-gold into the magnocellular preoptic area and the horizontal limb of the diagonal band, retrogradely labelled neurons were found in the homotopic region of the contralateral basal forebrain.

Forebrain inhibitory mechanisms: Cortical synchronization induced by basal forebrain stimulation
Experimental Neurology, 1962Abstract Cortical synchronization is of interest because of its similarity to the spontaneously occurring cortical spindle bursts associated with sleep and other states of central nervous system suppression. Although the diffuse thalamic projection system is primarily associated with this cortical response, other subcortical regions demonstrate ...

Functional Output of the Basal Forebrain
1991The basal forebrain is composed of many important components, one of which is the ventral striatum including the nucleus accumbens and olfactory tubercle. Both neuroanatomical and behavioral studies have provided important evidence implicating the ventral striatum as an interface between the limbic system and the extrapyramidal motor system (Kelley and

Sleep and basal forebrain activity
Science, 2020Neuroscience Different patterns of neural activity in the brain control the sleep-wake cycle. However, how this activity contributes to sleep homeostasis remains largely unknown. Adenosine in the basal forebrain is a prominent physiological mediator of sleep homeostasis. Using a newly developed indicator, Peng et al.

Local synaptic connections of basal forebrain neurons
Behavioural Brain Research, 2000Single, biocytin filled neurons in combination with immunocytochemistry and retrograde tracing as well as material with traditional double-immunolabeling were used at the light and electron microscopic levels to study the neural circuitry within the basal forebrain.

Transmitter cosynthesis by corticopetal basal forebrain neurons
Brain Research, 1989The objective was to determine if corticopetal basal forebrain neurons could co-synthesize different transmitters. Histochemical labeling of a molecular marker of connectivity (wheat germ agglutinin lectin-bound horseradish peroxidase [HRP]; axonal uptake and retrograde transport from neocortex) and immunohistochemical labeling of molecular markers of ...
