Basal Forebrain Amnesia

Cognitive and Behavioral Neurology, 2006
To provide new evidence of the existence of basal forebrain amnesia, as a different entity from hippocampal or diencephalic amnesia.Some authors consider that the characteristics of amnesia do not depend on lesion site, although others claim there are neuropsychologic differences between amnesias due to hippocampal, diencephalic, and basal forebrain ...

Basal Forebrain Infarction

Archives of Neurology, 1987
Following the repair of a ruptured anterior communicating artery aneurysm, a patient had a severe anterograde amnesia with sparing of other intellectual functions, apathy and loss of volition, altered arousal, and partial diabetes insipidus. Postmortem examination of the brain revealed bilateral destruction of the septal gray, nucleus accumbens, and ...

Moral Motivation and the Basal Forebrain

Neuroscience & Biobehavioral Reviews, 2020
Moral motivations drive humans to sacrifice selfish needs to serve the needs of others and internalized sociocultural norms. Over the past two decades, several brain regions have been associated with different aspects of moral cognition and behaviour. Only more recently, however, investigations have highlighted the importance of the basal forebrain for

Amnesia Following Basal Forebrain Lesions

Archives of Neurology, 1985
Of five patients with damage to the basal forebrain, four had lesions secondary to rupture of anterior cerebral or anterior communicating artery aneurysms, and one to the resection of an arteriovenous malformation. Computed tomographic scans and intraoperative reports confirmed damage to basal forebrain regions, which include septal nuclei, nucleus ...

Cortical input to the basal forebrain

Neuroscience, 1997
The arborization pattern and postsynaptic targets of corticofugal axons in basal forebrain areas have been studied by the combination of anatomical tract-tracing and pre- and postembedding immunocytochemistry. The anterograde neuronal tracer Phaseolus vulgaris leucoagglutinin was iontophoretically delivered into different neocortical (frontal, parietal,

The Basal Forebrain Corticopetal System Revisited

Annals of the New York Academy of Sciences, 1999
ABSTRACT: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, 1985
The 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, 1999
Studies 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, 2003
Abstract: 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, 1988
Following 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.
