High amounts of GABA in the system facilitate sedation or tranquility. Most tranquilizers and sedatives such as Valium contain GABA. Alcohol also contains GABA, which is credited with behavioral alterations after alcohol intake.
Side effects associated with using Dopamine include among others Severe allergic reactions evidenced through hives; breathing difficulties; rash; tightness in the chest; itching; swelling of the tongue, mouth, lips, face; chest pain; dizziness; an irregular heartbeat; pain, discoloration, or swelling from the points of injection. Dysfunctions in the dopamine system also result in disorders and diseases such as schizophrenia and Parkinson’s disease (Elias & Saucier, 2005).
Endorphins are recognized for playing an essential role in the depersonalization disorder. Antagonists of an opioid such naloxone and naltrexone are notable as having the capacity to treat depersonalization successfully (Saladin, 2009). The effects of endorphins are remarkable in persons suffering from depersonalization. Symptoms of depersonalization disappear entirely upon the administration of endorphins, which results in remarkable recovery levels. For instance, naloxone’s therapeutic effects are assertive of the integral role of endogenous opiods in the pathogenesis of the disorder ...

Central Nervous System Depressent Drugs
When alcohol is combined with CNS drugs the result can be devastating and as people who use CNS depressants often self-medicate with alcohol, the result can be harsh on the body and the system. 2.List and discuss the four types of individuals who abuse CNS depressants. The four types of individuals who abuse CNS depressants are those who are seeking to have sedation for stress relief, those seeking a euphoric response after they have built a tolerance, those seeking to counter the withdrawal affect of another drug they are dependent upon and those who combine their CNS depressants with alcohol...

The Peripheral Nervous System (PNS) depends on the afferent neurons, to deliver messages they receive from the sensory receptor to the brain, and the efferent neurons take the message of reaction from the brain, into the areas in the body. The central nervous system, which is made up of the brain and the spinal cord, depends on the interneurons, which consist 97 percent of the cells, besides beginning and ending their role within the system (Collins, 1989, p. 29). In the Central Nervous System (CNS), there are billions of neurons each with chemical and electrical capacities, to facilitate...

According to Kalat (2000) the relationship between the brain and every other inch of the body is one that cannot be replaced by any other functions. The brain is however, not helpful without the billon neurons incorporated in the human body. The human body needs the neurons to communicate commands from the brain. In an argument by Kalat (2000) neurons are the most important body cells in the human body. From the brain neurons are connected to the rest of the body through the spinal cord. The spinal cord contains the largest composition of neurons that convey commands from the brain to the rest...

The central nervous system, which is made up of the brain and the spinal cord, depends on the interneurons, which consist 97 percent of the cells, besides beginning and ending their role within the system (Collins, 1989, p. 29). In the Central Nervous System (CNS), there are billions of neurons each with chemical and electrical capacities, to facilitate communication via electrochemical means. A neuron is the basic unit of the nervous system, and functions through the distinguished body parts, the receiving end (dendrites) and terminal buttons separated by the axon.

Nervous System Research
While using physiological data, it is clear that nervous system modules are active local circuits, rather than mere anatomical entities. During construction, the specific activities that characterize each module are dependent on both extrinsic and intrinsic neuronal components, its phylogenetic history, and functional roles (Paxinos & Mai, 2013).

Drug Use and Neurotransmitters This is Your Brain on Drugs
Moreover, since the axons of neurons involved in norepinephrine release and reuptake in the coeruleus project into all major forebrain structures, the overall effect of cocaine is very powerful. In chronic users of cocaine, the brain becomes increasingly reliant on cocaine for the maintenance of these artificially elevated levels of serotonin, dopamine, and norepinephrine, especially those that are involved in the brain’s reward circuit. Indeed, the post-synaptic membrane could manufacture new receptors for cocaine in order to maintain high levels of neurotransmitters, leading to increased...
