Neuron Hacker

Neurohacking is the colloquial term for (usually personal or 'DIY') neuroengineering. It is a form of biohacking (qv) focusing on the brain and CNS. Strictly speaking it is any method of manipulating or interfering with the structure and/or function of neurons for improvement or repair.
                                                    

Coffee, alcohol, other drugs, and over the counter medicine are all forms of neurohacking. Every one of these substances alters or "tricks" the brain into desirable conditions. When drinking coffee, the brain is fooled into thinking the body has energy and keeps the consumer awake. The brain's neurons naturally produce adenosine as a byproduct which is monitored by the nervous system. Once the level of adenosine is at a certain point, the body will feel tired. Caffeine acts as fake adenosine and binds to the body's receptors. However, instead of disappearing, it blocks the adenosine receptors so the brain's stimulants, dopamine and glutamate, can work more freely. Since neurohacking is the interference with the structure and function of neurons, coffee is in fact a neurohack. Similarly, other substances that affect the brain and functions of neurons are also neurohacks. Alcohol is the most interesting form of neurohacking because it affects multiple neurotransmitters instead of just one. This is because alcohol is a fat soluble molecule. Since lipids are a major component of cell membranes, alcohol is able to enter the membranes of neurons and change their properties. Specifically, alcohol inhibits the glutamate receptor function, enhances GABA receptor function, raises dopamine levels, and raises endorphin levels. This causes all sorts of reactions, including liveliness and excitement. Alcohol also causes one to lose their anxieties, because of the effect of alcohol on GABA receptors. After alcohol affects the system, it causes the body to go through what is called neurotransmitter rebound. This is because when alcohol takes effect, it overuses the GABA system so when it wears off, the GABA system makes the body feel restless.
