LTP induction Exam Questions with Correct Answers What is LTP? - Answer-Long term potentiation (LTP) is a key form of synaptic plasticity that involves a sustained increase in the strength of synapses and is thought to play a fundamental role in the way we learn and store memories What are the key properties of LTP? - Answer-1. Input specificity 2. Co-operativity 3. Associativity What is input specificity? - Answer-Once induced, LTP at one synapse does not spread to other synapses; ra...
