    In order for these neurons to function properly, there must be a balance of chemical messengers, otherwise known as neurotransmitters. The predominant neurotransmitter in the reward system is dopamine because of its association with and direct effect on the reward system. The probability of a drug or behavior becoming addictive depends on the speed and intensity of the release of dopamine into the reward system (Juarez et al. 2016). Most drugs of abuse increase the activity of dopamine by interacting with dopamine synapses branching to the nucleas accumbens, or indirectly by regulating the activity of neurons in the Ventral Tegmental Area (Purves et al. 2012). Other drugs have a direct affect on the nucleas accumbens neurons to increase their responses to input (Purves et al. 2012). Drugs stimulate dopamine at a much higher amount than natural stimuli do; so, if there is only occasional use of a drug, the brain is able to correct itself and restore to proper balance once the drug is worn off (Juarez et al. 2016). However, if there is excessive drug use, the brain then increases its tolerance to the drug. This makes the reward system much less efficient because in order to achieve that same high, an ample amount of drugs must be taken (Gardner 2011). In severe cases, the drugs are not used for achieving a “high”, but rather to reach a normal state because the body…

    This reward circuit involves pathways from the ventral tegmental area to the nucleus accumbens, amygdala, and prefrontal cortex.

(qtd in Durrant, et…

They found that nests that were away from the burrow in sandy areas survived more than the ones in burrow aprons. They also learned that the nests that were in places that burned up during the research had a very low survival (Dziadzio et al., 2016). Many research studies are being done to find ways to change the environment to help prevent the extinction of the…
