Scientists call this new idea brain plasticityor neuroplasticity.

For this reason it is widely believed that synaptic plasticitymediates learning and memory.

Synaptic Plasticity and Memory: An Evaluation ..

The hypothesis that synaptic plasticity is a critical component of the neural mechanisms underlying learning and memory is now widely accepted. In this article, we begin by outlining four criteria for evaluating the 'synaptic plasticity and memory (SPM)' hypothesis. We then attempt to lay the foundations for a specific neurobiological theory of hippocampal (HPC) function in which activity-dependent synaptic plasticity, such as long-term potentiation (LTP), plays a key part in the forms of memory mediated by this brain structure. HPC memory can, like other forms of memory, be divided into four processes: encoding, storage, consolidation and retrieval. We argue that synaptic plasticity is critical for the encoding and intermediate storage of memory traces that are automatically recorded in the hippocampus. These traces decay, but are sometimes retained by a process of cellular consolidation. However, we also argue that HPC synaptic plasticity is not involved in memory retrieval, and is unlikely to be involved in systems-level consolidation that depends on HPC-neocortical interactions, although neocortical synaptic plasticity does play a part. The information that has emerged from the worldwide focus on the mechanisms of induction and expression of plasticity at individual synapses has been very valuable in functional studies. Progress towards a comprehensive understanding of memory processing will also depend on the analysis of these synaptic changes within the context of a wider range of systems-level and cellular mechanisms of neuronal transmission and plasticity.

If lots of these connections are involved thebrain activates various chemicals in the brain that cause new(connections) synapses to form and grow along with other connectingbrain elements to become separate unique

The current theory is that new knowledgeis initially stored by strengthening existing synapses which allow onepart of the brain to connect to another part of the brain.

We conclude that a wealth of data supports the notion that synaptic plasticity is necessary for learning and memory, but that little data currently supports the notion of sufficiency.">

Synaptic Plasticity and Memory - Sep 19, 2014

We review both classical and newly discovered properties of synaptic plasticity and stress the importance of the neural architecture and synaptic learning rules of the network in which it is embedded.

Synaptic Plasticity and Memory: An Evaluation of the Hypothesis …

In its most general form, the synaptic plasticity and memory hypothesis states that “activity-dependent synaptic plasticity is induced at appropriate synapses during memory formation and is both necessary and sufficient for the information storage underlying the type of memory mediated by the brain area in which that plasticity is observed.” We outline a set of criteria by which this hypothesis can be judged and describe a range of experimental strategies used to investigate it.

synaptic plasticity, and memory ..

Considering that the structure and function of Aplysia neuronsare so similar to vertebrate neurons, it seems quite plausible that memoryis stored by increasing synapses, increasing active zones and increasingtransmitter vesicles at selected neurons in the brain — although we mustawait definitive proof.

Reduced K+ outflow from the cell prolongs the action potential and allows more calcium to enter (2) serotonin and cAMP directly increase the numberof transmitter vesicles within 30 nanometers of the presynaptic membraneand (3) serotonin and cAMP directly influence another type of calcium channel to allow more Ca2+ into the cell.
