locus ceruleus

For example there is up to 70% loss of locus ceruleus neurons in Alzheimer's disease.

Nr2f6 knockout mice show defects in development of the locus ceruleus.

Vestibular dysfunction in the setting of increased locus ceruleus sensitivity may be a potential trigger.

Changes in the electrophysiological properties of cells in the locus ceruleus were shown.

The similarly melanin-pigmented cell bodies of the locus ceruleus produce norepinephrine.

It is released from the locus ceruleus, which is associated with most norepinephrine pathways in the central nervous system.

Both the substantia nigra and locus ceruleus can be easily identified grossly at the time of autopsy due to their dark pigmentation.

This suggests that degeneration of the locus ceruleus might be responsible for increased βA deposition in AD brains.

The norepinephrine from locus ceruleus cells in addition to its neurotransmitter role locally diffuses from "varicosities".

Normally, when a person is in a serene, unstimulated state, the "firing" of neurons in the locus ceruleus is minimal.

That route of signaling increases the rate of noradrenergic activity in the locus ceruleus, and the person becomes alert and attentive to the environment.

Restoration of normal locus ceruleus function may therefore be of potential therapeutic value in the treatment of Rett Syndrome.

Noradrenergic cell group A6 is a group of cells fluorescent for noradrenaline that are identical with the locus ceruleus, as identified by Nissl stain.

According to this theory, panic can be triggered by stimuli that set off a false alarm via afferents to the locus ceruleus, which then triggers the neuronal network.

It includes the pedunculopontine nucleus and the laterodorsal tegmental nucleus, among others, and is located near the raphe nucleus and the locus ceruleus.

We can see the locus ceruleus and the hypothalamus kicking in, libido increasing - healthy heterosexual libido - and depression decreasing -we can see it!"

The locus ceruleus is affected in many forms of neurodegenerative diseases: genetic and idiopathic Parkinson's disease, progressive supranuclear palsy, Pick's disease or Alzheimer's disease.

The depressed subjects showed significantly more evidence of deterioration in two areas of the brain stem, the locus ceruleus and the substantia nigra, than the nondepressed subjects, the researchers found.

If a stimulus is perceived as a threat, a more intense and prolonged discharge of the locus ceruleus activates the sympathetic division of the autonomic nervous system (Thase & Howland, 1995).

Alpha2-adrenergic receptor agonists, such as clonidine and guanfacine, act at noradrenergic autoreceptors to inhibit the firing of cells in the locus ceruleus, effectively reducing the release of brain norepinephrine (3).

Other physical manifestations of CTE include pallor of the substantia nigra and locus ceruleus, and atrophy of the olfactory bulbs, thalamus, mammillary bodies, brainstem and cerebellum.

The upper end of the sulcus limitans widens into a triangular depression called "suprior fovea" above suprior fovea sulcus limitans presents a flattend grey area called "locus ceruleus".

Parkinson's disease is at least in part related to dropping out of dopaminergic cells in deep-brain nuclei, primarily the melanin-pigmented neurons in the substantia nigra but secondarily the noradrenergic neurons of the locus ceruleus.

Noradrenergic neurons project bilaterally (send signals to both sides of the brain) from the locus ceruleus along distinct pathways to many locations, including the cerebral cortex, limbic system, and the spinal cord, forming a neurotransmitter system.

Another area that is active during symptoms of these disorders is the locus ceruleus, part of the brain stem that rouses the body to action by secreting norepinephrine, a brain chemical released when a person is under stress.
