Exploring synapses with a gigantic advantage

How does memory occur? And what about movement, or thinking? One key element to understand all these brain functions are the synapses. A synapse is the contact point between two neurons, where a signal is transmitted one-way, from one neuron to another. Specifically, from the pre-synaptic part of one neuron, to the post-synaptic part of another neuron.
