P19: Long-Term Potentiation
The term synaptic plasticity points to a series of persistent changes related to the activity of synapses. Long-term potentiation (LTP) is a reflection of synaptic plasticity that has an important role in learning and memory. LTP is a long-lasting increase of synaptic activity due to enhancement of excitatory synaptic transmission after a high-frequency train of electrical stimulations. Differe...
متن کاملP18: Signaling Pathway in Long-Term Potentiation
Synaptic plasticity in the central nervous system (CNS) of mammals has been discussed for many years. Several forms of synaptic plasticity of mammal’s CNS have been identified, such as those that occur in long-term potentiation (LTP). Different types of LTP have been observed in distinctive areas of the CNS of mammals. The hippocampus is one of the most important areas in the CNS that pla...
متن کاملInsulin Potentiation Therapy
Insulin potentiation therapy (IPT) is an unproven adjunct to cancer chemotherapy that uses insulin followed by sub-therapeutic doses of chemotherapy or other medications well below their proven efficacy. Theoretically, IPT boosts the pharmacologic efficacy of medications by increasing uptake into the cells of the body. During IPT enough insulin is given to induce hypoglycemic shock (perspiratio...
متن کاملPotentiation of latent inhibition.
Rats were given exposure either to an odor (almond) or a compound of odor plus taste (almond plus saline), prior to training in which the odor served as the conditioned stimulus. It was found, for both appetitive and aversive procedures, that conditioning was retarded by preexposure (a latent inhibition effect), and the extent of the retardation was greater in rats preexposed to the compound (i...
متن کاملVesicle biogenesis potentiation
n recent years, scientists have found evidence that new neurons arise in the brains of adult mammals, but little is known about the underlying mechanisms. Now, on page 209, Kowalczyk et al. find that in neurogenic regions of the adult brain only one cy-clin D protein, cyclin D2, is required for neural precursors to enter the cell cycle. To determine which cyclins were required for adult neuroge...
