* Long-term potentiation

Long-term potentiation ( LTP ) is a persistent increase in synaptic strength following high-frequency stimulation of a chemical synapse.

Long-term potentiation is only propagated to those synapses according to the rules of associativity and cooperativity.

* Long-term potentiation and depression

Long-term depression and long-term potentiation are two forms of long-term plasticity, lasting minutes or more, that occur at excitatory synapses.

Long-term potentiation, commonly referred to as LTP, is an increase in synaptic response following potentiating pulses of electrical stimuli that sustains at a level above the baseline response for hours or longer.

* Long-term potentiation ( LTP )

Long-term potentiation ( LTP ) is the opposing process to LTD. LTD is thought to result mainly from a decrease in postsynaptic receptor density, although a decrease in presynaptic neurotransmitter release may also play a role.

* Long-term potentiation ( LTP )

* Long-term potentiation ( neurophysiology ), a long-lasting enhancement in signal transmission between neurons

Research indicates that mice with a genetic deletion of the IL-1 receptor type I display markedly impaired hippocampal-dependent memory functioning and Long-term potentiation, although memories that do not depend on the integrity of the hippocampus seem to be spared.

However when mice with this genetic deletion have wild-type neural precursor cells injected into their hippocampus and these cells are allowed to mature into astrocytes containing the interleukin-1 receptor, the mice exhibit normal hippocampal-dependent memory function, and partial restoration of Long-term potentiation.

* Long-term potentiation

Long-term potentiation ( LTP ) is the process by which there is a signal transmission between neurons after the activation of a neuron, which has been known to play a strong role in the hippocampus in terms of learning and memory.

Long-term potentiation ( LTP ) in the hippocampal formation is an example model for neural plasticity.

Long-term potentiation ( LTP ) of synaptic strength at Schaffer collateral synapses has largely been attributed to changes in the number and biophysical properties of AMPA receptors ( AMPARs ).

Long-term potentiation

Long-term changes in synaptic efficacy in the hippocampus can be induced by different patterns of stimulation generating presynaptic and postsynaptic depolarization The theta burst stimulation of Schaffer collaterals can be sufficient to induce LTP by promoting the formation of filamentous actin in CA1 dendrites.

The evaluation typically includes neurological examination, routine EEG, Long-term video-EEG monitoring, neuropsychological evaluation, and neuroimaging such as MRI, Single photon emission computed tomography ( SPECT ), positron emission tomography ( PET ).

According to Medline Plus, " Long-term use betel-areca preparations has been associated with oral submucosal fibrosis ( OSF ), pre-cancerous oral lesions and squamous cell carcinoma.

* Long-term rivalry between the two main factions in Dutch society, the Staatsgezinden ( Republicans ) and the Prinsgezinden ( Royalists or Orangists ), sapped the strength and unity of the country.

Long-term use can precipitate the following effects: negative impact on liver function, permanent tooth darkening ( of a greenish tinge ), susceptibility to ulcers, and diminished sex drive.

Long-term liabilities of JNR were taken over by the JNR Settlement Corporation ( disbanded in 1998 ), and the corporation's remaining debts were transferred to the national budget's general accounting.

Long-term depression ( LTD ), in neurophysiology, is an activity-dependent reduction in the efficacy of neuronal synapses lasting hours or longer.

In the study Long-term Health Status of Danish Women with Silicone Breast Implants ( 2004 ), the national healthcare system of Denmark reported that women with implants did not risk a greater incidence and diagnosis of autoimmune disease, when compared to same-age women in the general population ; that the incidence of musculoskeletal disease was lower among women with breast implants than among women who had undergone other cosmetic surgery ; and that they had a lower incidence rate than like women in the general population.

Moreover, because only one study, the Swedish Long-term Cancer Risk Among Swedish Women with Cosmetic Breast Implants: an Update of a Nationwide Study ( 2006 ), controlled for tobacco smoking, the data were insufficient to establish verifiable statistical differences between smokers and non-smokers that might contribute to the higher lung cancer mortality rate of women with breast implants.

Long-term resistance, or systemic acquired resistance ( SAR ), involves communication of the damaged tissue with the rest of the plant using plant hormones such as jasmonic acid, ethylene, abscisic acid or salicylic acid.

Long-term care insurance ( LTC or LTCI ), an insurance product sold in the United States, United Kingdom and Canada, helps provide for the cost of long-term care beyond a predetermined period.

Long-term EC Comics fan Cochran auctioned Bill Gaines ' personal file copies of EC publications, as well as most pages of original EC artwork ( which, almost uniquely, Gaines had maintained ownership and possession of ), before being granted the reprint rights to the EC back catalog itself.

Long-term calorie restriction at a level sufficient for slowing the aging process is generally not recommended in children, adolescents and young adults ( under the age of approximately 21 ), because this type of diet may interfere with natural physical growth, as has been observed in laboratory animals.

Long-term use of sedative-hypnotics for insomnia lacks an evidence base and has traditionally been discouraged for reasons that include concerns about such potential adverse drug effects as cognitive impairment ( anterograde amnesia ), daytime sedation, motor incoordination, and increased risk of motor vehicle accidents and falls.
