Neurotransmitter

means that those with lower SLC6A15 have a higher chance of coping with stress and not developing depression. Stress is thought to alter excitatory neurotransmission, so by having a gene that could potentially help you not be as stressed out, neurotransmitters in your brain should produce and function…

Alcohol affects several neurotransmitters throughout the body, most prominently, those involved in stress and reward. The systems affected by this are dopamine systems, opioid systems, γ-aminobutyric acid systems, glutamate systems, and serotonin systems. Dopamine is the primary neurotransmitter involved in the reward pathway, which projects from the ventral tegmental area to the nucleus accumbens. Alcohol enhances…

axon terminal of the sending neuron and the dendrite of the receiving neuron. The neuron sending the message, called the presynaptic neuron, releases chemicals called neurotransmitters into the synapse. These neurotransmitters bind to receptors on the neuron receiving the message, or the postsynaptic neuron. If enough neurotransmitters bind to the postsynaptic neuron, the signal continues to the axon and the next neuron in the…

correctly when they have a psychological issue. “Anxiety and the Brain; An Introduction” addresses how neurotransmitters and hormones may influence the cause of anxiety. This article also supports the idea that brain imbalances cause anxiety. It further describes the connection that is shared between hormones and anxiety. “Many different hormones have an effect on brain chemistry and neurotransmitter production and balance, so if these hormones appear to be out of balance, anxiety many be the…

Furthermore, the two neurotransmitters that have been studied most in relation to Schizophrenia are dopamine and glutamate, which have yielded the Dopamine Hypothesis and Glutamate Hypothesis of Schizophrenia (Howes et al., 2015). Both of the aforementioned hypotheses attempt to trace Schizophrenic symptoms to a fluctuation in neurotransmitter activity in the brain. The updated version of the Dopamine Hypothesis states that schizophrenic…

Depression is define as the lost of interest and the feeling of sadness. Biologically speaking, depression is caused by an imbalance of neurotransmitters in the brain. We know that the major neurotransmitter affected is serotonin, other neurotransmitters like norepinephrine could be affected as well. Of course not all depressions are related to an organic matter. People tend to be depressed after an incident or frequent frictions with situation where self-esteem is compromised. What Albert Ellis…

information. Different drugs will work differently. In this presentation, I will describe how drugs affect the brain. In general, drugs work by imitating the brain’s neurotransmitters or over stimulating the brain’s “reward” circuit. Marijuana and heroin possess chemical structures that mimic naturally occurring neurotransmitters of our brain. These drugs are able to bind the receptors and activate the nerve cells. Because of differences of these drugs from the naturally occurring transmitters,…

2005). There are two types of synapses, electrical and chemical. A chemical synapse is separated by a synaptic cleft, a space filled with interstitial fluid. In response to a nerve impulse, a neurotransmitter is released into the synaptic cleft that binds to the membrane of the receiving neuron. Neurotransmitters are also released at the end of motor neurons, which stimulate the muscle fibres (Jenkins, Kemnitz & Tortora, 2010). Several neurotransmission systems have various roles in perception,…

paragraph said when we just finished reading it or simply daydreaming and not being able to stay on task” that are similar symptoms of ADD/ADHD and different variations of dementia if dopamine releases continue to decline as time passes (What are Neurotransmitters?,…

of Positron Emission Tomography (PET) and radioligands is helping to identify concentrations, activity, synthesis and transport of neurotransmitters during development and this may, in time, provide greater insight into the role of neurotransmitters in brain plasticity in localised areas.” Brain development is the core of conversation when it comes to neurotransmitters in this article. The authors have found that when you conduct multiple…
