Which stimulation technique leads to long-lasting memory through rapid, repetitive signals?

The most accurate choice for the stimulation technique that leads to long-lasting memory through rapid, repetitive signals is long-term potentiation. This process involves the strengthening of synapses based on recent patterns of activity and plays a critical role in synaptic plasticity, which is fundamental for learning and memory.

During tetanic stimulation, a burst of high-frequency stimulation is applied to a synapse, leading to a significant increase in the synaptic response. This repetition of signals enhances the release of neurotransmitters and affects the receptors and other molecules involved in synaptic transmission, resulting in a more robust connection between neurons. This is crucial for creating lasting memories, as it effectively fortifies the communication pathways in the brain over time.

The mechanism behind long-term potentiation involves various cellular changes, including increased calcium influx and the recruitment of more receptors to the synaptic membrane, which further solidifies the synaptic connection. As a result, this synaptic strengthening translates into long-lasting changes in neuronal function, enabling more effective communication between neurons during memory retrieval.
