In particular, the findings of specific neurological markers of individual preferences may have important implications for well-known economic models and paradigms. An example of this is the finding that an increase in computational capacity (likely related to increased gray matter volume) could lead to higher risk tolerance by loosening the ...
Alzheimer's disease (AD) is a chronic neurodegenerative disease that results in the loss of neurons and synapses in the cerebral cortex and certain subcortical structures, resulting in gross atrophy of the temporal lobe, parietal lobe, and parts of the frontal cortex and cingulate gyrus. [14]
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e ...
Numerous examples have been described of neurological disorders that are associated with mutated DNA repair genes (for reviews see [7]). Inadequate repair of DNA damages can lead directly to cell death and neuron depletion as well as disruptions in the pattern of epigenetic alterations required for normal neuronal function. [citation needed]
Transneuronal degeneration is the death of neurons resulting from the disruption of input from or output to other nearby neurons. [1] It is an active excitotoxic process when a neuron is overstimulated by a neurotransmitter (most commonly glutamate) [2] causing the dysfunction of that neuron (either damaging it or killing it) which drives neighboring neurons into metabolic deficit, resulting ...
This damage can cause long term effects such as but not limited to; memory loss, confusion, and loss of cognitive function. The brain damage caused by radiation depends on where the brain tumor is located, the amount of radiation used, and the duration of the treatment.
This type of nerve damage may cause paralysis of the motor, sensory, and autonomic functions, and is mainly seen in crush injury. [2] If the force creating the nerve damage is removed in a timely fashion, the axon may regenerate, leading to recovery. Electrically, the nerve shows rapid and complete degeneration, with loss of voluntary motor units.
An example is through the nicotinic acetylcholine receptor (nAchRs), which is a receptor commonly found along the surfaces of the cells that respond to nicotine stimulation, turning them on or off. Aβ was found manipulating the level of nicotine in the brain along with the MAP kinase , another signaling receptor, to cause cell death.
