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 transmission between two neurons. The opposite of LTP is long-term depression, which … 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 increase significantly with age, giving … Ver mais While the long-term potentiation of synapses in cell culture seems to provide an elegant substrate for learning and memory, the … Ver mais • Neuroplasticity • Actin remodeling of neurons • Transcranial direct-current stimulation • Post-tetanic potentiation 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 NMDA receptor-dependent LTP exhibits several properties, including input specificity, associativity, cooperativity, and persistence.
