Answer:
Long-term potentiation
Explanation:
The learning processes can be classical conditioning and neuronal conditioning, whereas, the types of memory can be short-term or long-term. All the learning and memorizing processes in our brain depends on our ability to detect and respond to environmental changes. These responses are triggered by formation of thousand synapses in our brain among thousands of neurons responsible for signal processing and transduction. The signal processing is performed via action potential generation which either amplifies or restricts a stimulus; thus inhibiting or exciting the chemical exchange necessary for response. Long-term potentiation is the basis of learning and memory because it strengthens the synaptic activity and potentiates long-lasting signal transduction by producing high intensity action potentials. Therefore, the information keeps transferring and stored in the memory and learning centers.
