Hallucinogens Essay

Great Essays
Hallucinogens are a chemical substance that causes hallucinations. Hallucinations, derived from Latin, álucinari, means to ‘wander in the mind.’ Hallucinations includes all sensory perceptions whether real or not. Psychedelics, Greek derived, translates to ‘soul and mind manifesting’ and are a class of hallucinogens that are useful tools in gaining understanding of how the brain, mind and body works. The study is complex and requires a broad and deep knowledge of the various mechanisms and interactions of neurons at a molecular and cellular level. Recent studies using the Default Mode Network (DMN) give potential findings, at a neural network level. Further studies to establish the anatomical and com-putational functioning are needed (R.B. …show more content…
It is then actively transported through the blood brain barrier (BBB) into the central nervous system. From here DMT enters synaptic vesicles through serotonin transporters (SERT), via vesicular monoamine transporter 2 (VMAT2), for up to seven days. Sigma-1 receptors are located in-side the presynaptic endoplasmic reticulum (ER) which regulates calcium ion flow lead-ing to change of gradients in sodium and po-tassium channels with its binding. This caus-es a signal transduction by depolarizing and hyperpolarization triggering an action poten-tial to move through the synapse, open-ing/closing, excitatory/inhibitory, leading to binding on voltage gated receptors, like G-proteins, second messengers and membrane bound effector proteins, coupled with Guano-sine triphosphate- GTP for RNA synthesis. Figure 3, taken from Kanesha Laboratories, illustrates the complex, however incomplete, interactions involved. DMT interaction has been added to show how the reuptake pro-teins create excitatory/inhibition, ago-nist/antagonist

    Amphetamines are characterized as dopamine releasers that elevate levels of dopamine in the synaptic cleft, the space between neurons at a nerve synapse, by four distinct mechanisms. The primary mechanism involves amphetamine acting as a substrate for dopamine transporters. The transporters are responsible for pumping dopamine out of the synaptic cleft back into the cytoplasm of presynaptic neurons. The binding of amphetamines to dopamine transporters, inhibit dopamine uptake resulting in a larger concentration of dopamine remaining in the cleft (Calipari & Ferris, 2013). The other mechanisms by which amphetamine increases the concentration of dopamine in the synaptic cleft are: binding of amphetamines to the presynaptic membrane of dopaminergic neurons to induce the release of dopamine from the nerve terminal; binding to monoamine oxidase to inhibit the enzymatic breakdown of cytosolic dopamine; and binding of amphetamines to dopamine re-uptake proteins in order to force the protein to act in reverse and transport dopamine out of the nerve terminal into the synaptic cleft (Ellinwood et al.,…

    The synapses have receptors on them and the response of the drug depends on which receptor it binds to. Each receptor has its own response to a very specific drug. These responses can sometime benefit or harm the person depending on what drug binds to which receptor. 7.

    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 be effective. The first step is biosynthesis, which is when the presynaptic cell synthesizes neurotransmitters when a precursor interacts with an enzyme. For example, when the precursor tyrosine interacts with the enzyme tyrosine hydroxylase, it becomes L-Dopa, and when that precursor interacts with the enzyme DOPA decarboxylase, the outcome is dopamine.…

    Methylphenidate, commonly known as Ritalin, is a commonly prescribed central nervous system stimulant used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. Medical use of methylphenidate began in 1960 and an estimated 2.4 billion doses are prescribed a year. Methylphenidate is thought to act through the inhibition of dopamine and norepinephrine transporters in neurons, especially those of dopaminergic pathways of the brain. The dopaminergic pathways of the brain are composed of neurons that synthesize and transmit the neurotransmitter dopamine, to different regions of the brain. Dopamine signaling from these pathways is associated with several integral cognitive processes including reward-motivated behavior, motor…

    The medical field is transitioning into what neuroscientists have called “the age of the brain.” Medicine is beginning to grasp the significance of mental illness. In the past medicine dismissed the severity of mental illness, providing diagnoses with more “substance.” However, today mental illness is treated as a very real sickness, which can be treated with medication and therapy. Understanding the neural connections within the brain will allow physicians to distinguish the difference between patients at the neuronal level.…

    LSD was first made by Albert Hoffman, a Swiss scientist, in 1938. LSD (short form) actually comes from its early name LSD-25 which is an abbreviation for the German "Lysergsaure-diethylamid" followed by a sequential number. Hoffman was not only the first to make LSD, he was also the firwst to ingest and learn the psychedelic effects of this drug. Hoffman died April 29, 2008, at the age of 102. LSD is a semi-synthetic drug, this means that it occurs both in nature and is part man-made.…

    Dopamine is the main reward pathway as well as being a hormone it’s the main factor that impacts an individuals feeling of pleasure. However, when taking a drug this can work in place of the chemical neurotransmitter, therefore interfering with the balance of this chemical to make it imbalanced and therefore disrupting behavior of the typical neural communication. An example of this is the use of conventional antipsychotic drugs in the treatment of schizophrenia, these bind to dopamine receptors but don’t actually stimulate them and consequently because of this these are known as antagonists, this therefore has the effect that it reduces stimulation of dopamine particularly in D2 receptors; doing this reduces the amount of dopamine transmitted to the postsynaptic neuron decreasing and by doing this it therefore stops the brain receiving this excess of dopamine delaying the effects which is thought to cause schizophrenia when there is an excess eliminating the symptoms (Wiley & Sons,…

    Neurotransmitters are the chemical messengers’ comprising of multiple endogenous chemicals allowing neurotransmission across synapses. During the neurotransmission a chemical is released from the axon terminal of a presynaptic neuron fabricating millions of synaptic connections that play a major role in modelling everyday activities. Through the process of staining and stimulations in experiments, researchers have now identified more than 100 unique chemical messenger types which can further be classified in several ways as such- amino acids, gasotransmitters, monoamines, trace amines, peptides, purines etc. However, in my paper I would like to mainly focus on the most prevalent neurotransmitter “Glutamate” which is responsible for postsynaptic…

    The cells are grouped in clusters just like terminal wires and group of nerve bundles are called tracts which use chemical messengers to send information like the computer and electrical wires send to the computers brain. In the brain the wires or chemical messengers are called neurotransmitters that help the brain to communicate (Smith, 2013). Smith (2013) says the neurotransmitter are chemicals that discharge into gaps and other receptor that have names like endorphins, dopamine, GABA, Serotonin and norepinephrine to name a few. As the body introduces drug chemicals inside Smith (2013) explaining that the brain has a barrier which works to block them from reaching the brain called the ‘Blood-brain Barrier”. The lipid –soluble substance are able to past through the blood-brain barrier according to Smith by changing the effect on the mind and their behavior (Smith, 2013).…

    Serotonin is a neurotransmitter responsible for processes within our brain such as our mood, sleep, appetite, and perception. It is While serotonin is primarily found in the gastrointestinal tract the brain only utilizes serotonin produced within the brain. It is stored within the brain until it is needed. However, after our bodies have used the serotonin needed serotonin transporters remove the additional serotonin from the brain. Ecstasy which is an illegal street drug also referred to as a designer drug binds with the serotonin transporter that affects the brain.…
