Hippocampal Function in Cognition

Psychopharmacology, 2004
Any consideration of cognitive disruption in schizophrenia quite naturally leads to questions concerning the cellular and molecular mechanisms underlying normal cognition. This review will describe emerging models for the cellular basis of cognitive processing in the hippocampus.This review will describe results from several laboratories that have used

Hypoglycaemia and cognitive function

Diabetes, Obesity and Metabolism, 2004
Acute hypoglycaemia impairs cerebral function, and available data indicate that cognitive performance becomes impaired at a blood glucose level of 2.6–3.0 mmol/l in healthy subjects. Methodological problems limit comparisons between studies, but in general complex tasks are more sensitive to hypoglycaemia than simple tasks, and some cognitive abilities

Schizophrenia and cognitive function

Current Opinion in Neurobiology, 2000
Schizophrenia is often associated with cognitive deficits, particularly within the domains of memory and language. Specific cognitive deficits have recently been linked to psychotic phenomena, including verbal hallucinations and disorganized speech.

Cognitive functioning and anxiety

Psychological Research, 1987
Various possible differences in cognitive functioning between those high and low in trait anxiety are considered. Particular emphasis is paid to the hypothesis that individuals high in trait anxiety tend to approach threatening stimuli, whereas those low in trait anxiety tend to avoid such stimuli. The evidence indicates that there are such differences

Functional cognitive disorders

Zhurnal nevrologii i psikhiatrii im. S.S. Korsakova, 2022
The article provides an overview of scientific publications devoted to the study of the problem of functional cognitive disorders (FCD), which are one of the variants of functional neurological disorders (FND). The authors provide data on the frequency of occurrence of this pathology, the differences between the concepts of FCD and «subjective ...

Stress and cognitive function

Current Opinion in Neurobiology, 1995
Stress affects cognition in a number of ways, acting rapidly via catecholamines and more slowly via glucocorticoids. Catecholamine actions involve beta adrenergic receptors and also availability of glucose, whereas glucocorticoids biphasically modulate synaptic plasticity over hours and also produce longer-term changes in dendritic structure that last ...

Homocysteine and Cognitive Function

Seminars in Vascular Medicine, 2005
The prevention and treatment of age-related cognitive impairment and dementia is one of the greatest and most elusive challenges of our time. The prevalence of dementia increases exponentially with age, as does the prevalence of those with micronutrient deficiency.

Cognitive Functions of the Fetus

Ultraschall in der Medizin - European Journal of Ultrasound, 2018
AbstractThe human brain is intricately designed to execute cognitive functions, such as perception, attention, action, memory and learning. The complete nervous system is active during prenatal development and the aim of this review is to present data on fetal cognitive functions.

Mental and cognitive functions

2016
Along with an increasing aged population, cognitive disorder or dementia is the most serious problem in the world. Cognitive functions are composed of several higher brain functions, including memory; This chapter discusses anatomical basis of each of these functions, and symptoms and syndrome causes by impairment of each function or combination of ...

Cerebellum: Cognitive Functions

2015
In the nineteenth century, researchers reached a consensus on the basis of animal ablation experiments that damage to the cerebellum leads to motor disorders but does not affect its sensory or cognitive functions. This model has been so influential that for over 100 years, the cerebellum has been considered to be strictly involved in motor control ...
