Dopamine receptor

schizophrenia can be caused by various alleles in a genome that interact together. Signs and symptoms of the disease are linked through the Disconnection hypothesis that allows for molecular and neuronal pathophysiology. This pathophysiology allows for receptor functions and neurotransmitter systems to be studied and related to genomic…

the brain very fast, and they bind to receptors on cells. Some of these bind to cells that involve our feelings, such as pleasure and pain. Some people feel a “rush” when they use substances. The brain chemicals are affected by drugs because the chemicals in the drugs are very much like the chemicals in our brain. These drugs are basically imposters and the neurons recognize them. The neurotransmitters are the “feel goods” in our brains. For example: Dopamine is found in the limbic system, this…

Schizophrenia is a severe mental disorder that affects approximately 23.6 million people globally (Global Burden of Disease Study 2013 Collaborators, 2015). The disorder is marked by delusions, hallucinations, disorganized speech and behavior, which typically result in problems related to self-care and general functioning in social and occupational settings (American Psychiatric Association, 2000). Despite the first detailed clinical description having been written in 1810 (Haslam, 1810), and…

coming off. Ibogaine acts on almost all receptors in the brain, but primarily the…

Beneficial effects of the beta adrenergic antagonists in the treatment of the chronic obstructive pulmonary disease. It is not uncommon for the patients to present with two or more disease states at the same time. Thus, the management of such concomitant disease states may be pharmacologically challenging as it is, for example, in the treatment of the chronic obstructive pulmonary disease (COPD) and hypertension (HTN) with a compelling indication of the post-myocardial infarction (post-MI).…

The physiological processes of a mammal are in a unique balance where any deviation from the normal can result in a pathological condition. For example, mammals require a continuous intake of nutrients to ensure that every vital process can be maintained. If these processes are not maintained; the organism will begin to absorb its own nutrients, thereby reducing the availability of resources within the organism (Odette, 2005). An organism that is absorbing its own nutrients will be unable to…

unfortunately, two thirds of this population are between 12 and 17 years old (Sofuoglu, Sugarman & Carroll, 2010). Marijuana contains an active ingredient, tetrahydrocannabinol (THC) which alters the human central reward pathway by stimulating cannaboid receptors in the place of anandamide, a hormone of the endocannabinoid system, ultimately causing a sense of euphoria, a common attribute of other abused…

Intrinsic Cardiac Activity: The first peak of the electrocardiogram graph corresponded to the atrial contraction of the heart. The second peak of the electrocardiogram graph corresponded to the ventricular contraction of the heart. The third peak observed corresponded to the relaxation of the heart. Frank-Starling Mechanism: There was no significant trend observed in ventricular contractile force in response to increasing imposed length of the heart (Fig 1a). A maximum ventricular contractile…

Analysis of Adenosine receptor blockage’s effects on the electrophysiology of HCTP/OR producing neurons of the Hypothalamus – receptor blockage mediated by Caffeine Introduction In this experiment, the quantification of firing rate changes on a specific neural sub-group will be analyzed via whole cell patch-clamping and the application of the common psychoactive drug-caffeine. The significance of quantifying the electrical signaling of the chosen neuron is to proportionally quantify the…

Disorders of sexual development (DSD) have been a topic of great interest as of late. Intersex, at its most basic definition, is when one does not ‘fit’ into the binary gender structure most commonly subscribed to in Western civilization; or, rather, having a variation of sexual characteristics or a combination other than the more common female to XX and male to XY. Research shows that 1.7% of the population has a DSD, considering the current population of the U.S., that would be approximately…
