Dopamine receptor

The first thing I think of when I hear the words digital addiction is pornography, but that is not the case for this session. On Friday, September 23, 2016, I attended the pre-conference of Faith and Science at Evangel. It is talking about the biology of sin. I attended a session called “Digital Addiction” by Jeremy Harris and Erica Harris. Digital addiction deals with, the internet, screens, social media, smartphones, etc. This session focused on Smartphones on so many people cannot put their…

dopaminergic systems is one of the biological characteristics of aging in the brain and may contribute to changes in cognitive and motor functions in old individuals. Furthermore, aging-dependent norepinephrine (NE) loss occurs earlier than that of dopamine (DA) and a functional noradrenergic system may influence dopaminergic activities as evidenced by the fact that an intact noradrenergic system is neuroprotective on nigrostriatal dopaminergic neurons, and endogenous NE…

working and something needed to change. Methadone, one of the medications used for MAT, was developed as a research project to respond to this heroin epidemic (Joseph, Stanfliff and Langrod). Methadone is a full agonist; it activates the opioid receptors and…

The brain is an organ made up of cells known as neurons which communicate using chemical signals that involve neurotransmitters such as serotonin, norepinephrine, and dopamine. The turnover model, which is composed of five steps, explains the process neurotransmitters undergo in order for them to be released and have an effect. It is important to note that drugs specifically target one or more of these steps in order to…

The nervous system is composed of two main parts which are the central nervous system and the peripheral nervous system. The central nervous system includes the brain and nerve cords like the spinal cord while the peripheral nervous system includes the motor nerves and sensory nerves. There are two main types of support cells in the nervous system which are glial cells and neurons. The neurons' function in the system is to receive and send electrical signals. The glial cells provide insulation…

Being able to reproduce and bring new life to earth is a blessing many persons continue to adore. A baby’s first step, first word, and first smile are only a few of an abundance of ‘firsts’ parents look forward to recording or scribbling down in their infant’s baby book. The sullen reality is not all ‘firsts’ are going to aspire great success. Drug abuse is a very serious issue in the United States. According to Erik Erikson’s stages of psychosocial development, “teenagers work at refining a…

No time to sleep but lets try and regulate and understand what is happening. Discovered in 1958 by, J. Woodland Hastings and Beatrice M. Sweeney. But kicked off in 1998 when a new photo receptor was discovered. Today even mobile phone have options to warm the led light. Decreasing the affect on the circadian rhythm. These reactions are autonomic. Its as if you are medicating yourself through your eyes. Light: Medicine of the future is a…

When Amy placed her finger on the burner, the general sensory receptors (Ireland, 2012) in her skin sent the message that it was hot. The sensory neuron is responsible for carrying the information. This is an afferent neuron, because it is taking the message to the central nervous system. The message is carried through the peripheral nervous system to the spinal cord. Once it reaches the spinal cord, association neurons pass the message to motor neurons. Motor neurons, which are efferent, carry…

disruptions or polymorphisms in the glutamate system (yet to be determined) may lead to a hyperexcitatory effect of glutamate[1-3]; second, increased concentrations of dopamine may result in higher levels of activated of D1 receptors, which will consequently overactivate the direct pathway[3]; third, a hypersensitisation of the 5-HT1B receptor may lead to a decrease in serotonin levels and a subsequent impairment in the communication within the circuit, which would explain why some SSRIs improve…

We’ve all heard of the runner’s high. It comes from the endorphins produced during prolonged exercise, and it’s based on the theory that these chemicals interact with receptors in our brain to reduce pain perception, and that they may also give you a very pleasant euphoric feeling. But a new study published in the Proceedings of the National Academy of Sciences refutes that theory, and poses a different one: that high is caused by a different substance called endocannabinoids. The Body’s…
