Neurotransmitter

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…

Receptors belong to class of proteins. Binding of some substance to the receptor brings about changes that direct the actions of cell containing receptor. Ligand is the molecule that binds to the receptor and it can be a peptide, a hormone, neurotransmitter, drug or a toxin etc. Each receptor possesses two functional domains: recognition domain that binds the ligand such as hormone, and a coupling domain involved in signal transduction. Signal transduction includes the events within the cell…

Important Vocabulary (highlighted in the handout): Stimulus, neurons, dendrites, neurotransmitters, axon, myelin, action potential, graded potential, transmembrane potential, neuroglia, cerebrum, spinal cord What is the central nervous system? It’s a system which consists of the nerves in the brain and spinal cord. This system only makes up about 3% of a human’s body weight but serves a vital function, gathering information about and reacting to its environment and any stimulus. Don’t Shoot the…

acting on neurons and various neurochemicals. It can modify cell membranes, along with their ion channels, enzymes and receptors. Alcohols’ effect on the central nervous system (CNS) is largely due to its action on different neurotransmitters. A major inhibitory neurotransmitter in the central nervous system is gamma-aminobutyric acid (GABA). Alcohol amplifies the effect of GABA by binding to and stimulating GABA receptors, causing the opening of ion channels. This allows for an influx of…

Neurotransmitters are proteins produced by the nervous system. To be classified as a neurotransmitter, a chemical must bridge the synapse and induce an electric current in a dendrite. Neurotransmitters may either excite the dendrite or inhibit it, and the same neurotransmitter may be excitatory or inhibitory in different neural circuits. Neurotransmitters that increase activity in the neuron are said to be excitatory. In contrast, neurotransmitters that decrease activity in…

Neurotransmitters travel from one neuron to the other through electrical current, it is either inhibitory or excitatory, this means that the cell either increases or decreases its membrane potential. Synthesis control is crucial for neurotransmitters, it ensures the precursor of neurotransmitters. Moreover, end product inhibition recognizes how much neurotransmitters are in the synaptic cleft. In schizophrenia, neurotransmitters such as dopamine, glutamate, GABA…

In 1956, the U.S. Food and Drug Administration first approved the use of Ritalin as an oral tablet with the active ingredient as methylphenidate hydrochloride. At first, Ritalin was mainly prescribed for use to treat chronic fatigue, depression, narcolepsy, and to offset the sedating effects of other medications. During the 1960s researchers focused on Ritalin as a form treatment of "hyperkinetic syndrome," which in now commonly known as Attention Deficit Hyperactivity Disorder (ADHD). In the…

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. Present empirical evidence to support the position that the neurotransmitter is the signaling agent for…

other neurotransmitters. Evidently, newer treatments are helping in blocking dopamine receptors as well as several serotonin receptors, including 5HT2 which the most studied. Others include GABA neurons which are also regulated by dopamine. Treatment of Schizophrenia In schizophrenia treatment, medications are the cornerstone (Fuller et al., 2015). The most common type of medications is antipsychotic medications, which help in controlling symptoms through affecting brain neurotransmitters…

Neurotransmitter damage, short term effects, and long term effects challenge the physical development of a teen, along with setting up their body for failure for the rest of their life. Mental inhibition caused by substance abuse also challenges learning and…
