\section{Neurological Processes Related to Learning}  \paragraph{}  The way we learn new behaviors is heavily influenced by specific neurotransmitters, namely dopamine because it is known to reward specific behaviors by making us feel good.\cite{Juan_2014} It is interesting to note the brain's natural reward system affecting behavior and, more specifically learning. Through psychology and neuroscience, we know there are various forms of learning such as classical conditioning from Pavlov's dog experiment and instrumental conditioning from the Skinner Box that showed the effects of reinforcement and punishment on behaviors. We now know that our brains must detect, decode, and respond to a change through various perceptual functions. For instance, visual stimuli trigger responses which form a magnitude of synapses in our brains. Our eyes are an example of a perceptual apparatus that takes in light in various forms of frequencies and amplitudes, which are then converted into electrical currents and travelled to the brain via the optic nerve through a large number of action potentials. The brain interprets these signals and responds to this perception of vision. Learning and memorization is the result of fostering neural efficiency through the creation of new synaptic connections or reinforcing the strength of existing ones.\cite{Reinis_1986} When neurons fire together they are essentially wiring together, which is referred to in neuroscience as synaptic plasticity. A vast amount of brain research has been conducted over the last ten years to unravel the underpinnings of learning and memorization. Now, it is understood that learning is formed by changes in synaptic connections. Learning is affected most when postsynaptic neurons are affected by anatomical and biochemical alterations administered on axons.\cite{21204354} Beginning studies on learning used electrical stimulation on the hippocampus. These studies revealed that the stimulation produced more long term potentiation. The findings of long term potentiation explained the process we use to remember in our brain.\cite{21204430} Essentially, when a synapse continually activates as the postsynaptic neuron fires, changes will occur in the composition of the synapse which will strengthen it.\cite{Blair_2001}
