Morphological changes associated with long-term potentiation.
Long-term potentiation (LTP) is a long-lasting form of synaptic plasticity induced by brief repetitive afferent stimulation that is thought to be associated with learning and memory. It is most commonly studied in the hippocampus where it may last for several weeks, and involves the synthesis of new proteins that might play a structural role. In this review we summarize the evidence in favor of...
متن کاملChanges during Long-term Growth
Growth rate and concentrations of sulfates, sulfides, proteins and glucosamine were analyzed during long-term (over 60 days) incubation of Desulfotomaculum acetoxidans DSM 771. To imitate natural conditions, incubation was done in obligate anaerobic conditions in three series, without stirring or shaking. In the first 2–3 days of incubation (lag phase), only a decrease of the sulfate level occu...
متن کاملP19: 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 کاملSimulation of Long-term Returns with Stochastic Correlations
This paper focuses on a nonlinear stochastic model for financial simulation and forecasting based on assumptions of multivariate stochastic correlation, with an application to the European market. We present in particular the key elements of a structured hierarchical econometric model that can be used to forecast financial and commodity markets relying on statistical and simulation methods. The...
متن کاملMacroprolactinomas: serial MR imaging in long-term bromocriptine therapy.
PURPOSE To study the changes in macroprolactinomas during long-term bromocriptine therapy by means of serial MR imaging, and to correlate the findings to the serum prolactin (S-PRL) levels. PATIENTS AND METHODS Thirteen patients with macroprolactinomas were studied before and during bromocriptine therapy; six to 11 MR examinations were performed with a duration of follow-up of 22 to 74 months...
