Web23 de abr. de 2010 · 2. Introduction There are two basic mechanisms for regulating blood pressure: (1) short-term mechanisms. regulate blood vessel diameter, heart rate and contractility (2) long-term mechanisms. regulate blood volume Blood Pressure = cardiac outputxperipheral resistance Any change in … Long-term potentiation (LTP) is a persistent increase in synaptic strength following high-frequency stimulation of a chemical synapse. Studies of LTP are often carried out in slices of the hippocampus, an important organ for learning and memory. In such studies, electrical recordings are made from cells and plotted … Ver mais In neuroscience, long-term potentiation (LTP) is a persistent strengthening of synapses based on recent patterns of activity. These are patterns of synaptic activity that produce a long-lasting increase in signal … Ver mais Since its original discovery in the rabbit hippocampus, LTP has been observed in a variety of other neural structures, including the cerebral cortex, cerebellum, amygdala, and many others. Robert Malenka, a prominent LTP researcher, has suggested that LTP … Ver mais While the long-term potentiation of synapses in cell culture seems to provide an elegant substrate for learning and memory, the contribution of LTP to behavioral learning — that is, learning at the level of the whole organism — cannot simply be … Ver mais • Neuroplasticity • Actin remodeling of neurons • Transcranial direct-current stimulation Ver mais Early theories of learning At the end of the 19th century, scientists generally recognized that the number of neurons in the adult brain (roughly 100 billion ) did not … Ver mais NMDA receptor-dependent LTP exhibits several properties, including input specificity, associativity, cooperativity, and persistence. Ver mais The role of LTP in disease is less clear than its role in basic mechanisms of synaptic plasticity. However, alterations in LTP may contribute to a number of neurological diseases, … Ver mais dewa research center
