Dementia is a general term in the same way that heart disease is a general term. Dementia is caused by damage to brain cells. This damage interferes with the ability of brain cells to communicate with each other. When brain cells cannot communicate normally, thinking, behavior and feelings can be affected. [110] There are many signs of dementia.
The latest research looked at a part of the brain ... Samples from eight of the cadavers contained microplastics — tiny bits of plastic that ranged from 5.5 micrometers to 26.4 micrometers in ...
It is thought that damage to the nucleus basalis and its cortical projections are implicated in forms of dementia, notably Alzheimer's dementia and Parkinson's disease dementia. There have been studies on the use of deep brain stimulation to the nucleus basalis, in the treatment of dementia, and while giving some positive results trials are ...
Information about the structure and function of the human brain comes from a variety of experimental methods, including animals and humans. Information about brain trauma and stroke has provided information about the function of parts of the brain and the effects of brain damage. Neuroimaging is used to visualise the brain and record brain ...
In vertebrates, the part of the brain that plays the greatest role is the hypothalamus, a small region at the base of the forebrain whose size does not reflect its complexity or the importance of its function. [104] The hypothalamus is a collection of small nuclei, most of which are involved in basic biological functions.
Vestibular nerve (part of cranial nerve 8) – the main equilibrioception-related cranial nerve; Peripheral chemoreceptor in the brain – monitors the carbon dioxide and oxygen levels in the brain Chemoreceptor trigger zone – area in the brain that receives inputs from drugs and hormones, and controls vomiting
Researchers were able to improve memory in mouse models of dementia through an experimental nasal spray treatment. ... amyloid, form between dying brain cells, while tangles, made up of tau ...
Embryonic vertebrate subdivisions of the developing human brain hindbrain or rhombencephalon is a developmental categorization of portions of the central nervous system in vertebrates. It includes the medulla , pons , and cerebellum .
