Enhancing an inhibitor has the effect of making a person sluggish. Also, alcohol weakens the excitatory neurotransmitter glutamine, which enhances the sluggishness even farther. The Central Nervous System: The central nervous system (CNS) includes the brain, the spinal cord, and the nerves originating from it. Sensory impulses are transmitted to the CNS and motor impulses pass from it. When alcohol acts on the CNS, intoxication occurs, affecting emotional and sensory function, judgment, memory and learning ability.
It effects the transfer of the impulse to another nerve strand, a muscle strand, or another structure. They lead signals between nerve cells, called “neurons.” Neurotransmitters are chemicals that live inside brain cells. The brain uses neurotransmitters to tell your heart to beat, your lungs to breathe, and your stomach to digest. They can also affect mood, sleep, concentration, weight, and can cause contrary symptoms when they are out of stability. There are many different types of neurotransmitters.
Technical Notes Exploratory Analysis The histogram, box plot and dot plot all show the data is slightly right skewed: the median (1088.65) is slightly less than the mean (1102.59) and the skewness statisti is a fairly small positive value (0.58). Checking Assumptions The independence of the observations appears to be satisfied from the data description. The Shapiro-Wilk Normality test shws strong evidence gainst the hypothesis that the underlying distribution is normal (P-value=0.008103). The Normal Q-Q plot shows a slight curve through the points indicating slight right skewness. Although the data are slightly right skewed, because of the large sample size(n=152) our inference on the mean is valid, by the Central Limit Therom.
Acetylcholine acts as a neuromodulator which engage in direct synaptic transmission between specific neurons. In the CNS acetylcholine plays a role in attention and arousal in the PNS it works as a major part of the autonomic nervous system and works to activate muscles (Waymire, 1997). Acetylcholine is involved in voluntary movement, learning, memory, and sleep. | | | | Pharmacological agent prescribed to increasethe neurotransmitter: | List three possible side effects linked to this agent: | To increase the neurotransmitter in the body the supplement choline bitartrate and CDP-Choline and herbal agents ginseng and ginkgo biloba (Moore, 2013). | 1) Low blood pressure | | 2) Stomach ache | | 3) Increase perspiration and salivation (Moore, 2013) | Example of a neurological disorder, disease, or condition where this agent occurs | List possible risks associated with not taking this agent for the disorder, disease, or condition: | A severe autoimmune muscular disease by varying progressions of defects of the skeletal muscles in the body is known as myasthenia gravis.
Outline and evaluate one or more biological explanations for schizophrenia The biochemical explanation is one explanation for the cause of schizophrenia in terms of the release of neurotransmitters. This suggests that schizophrenia could be caused by an excess amount of dopamine in the brain. This is due to receptor cells requiring dopamine to fire so with a large amount of dopamine present it is activated too much and too many messages are sent. This is what could account for the confused and the erratic behaviour which is seen in schizophrenic patients. Support for this theory is the effect of amphetamines.
(Altman et al.1996). Addiction as a whole may be either substance addiction such as drug, alcohol, nicotine and other psychoactive drugs and stimulants or behavioral addictions. The type of behaviors which some people have identified as being addictive include gambling, food, sex, pornography, use of computers, playing video games, use of the internet, work, exercise, spiritual obsession (as opposed to religious devotion), cutting, and shopping. Behaviors like gambling have been linked to the new found idea of the brain’s capacity to predict rewards. The reward system can be triggered by early detectors of the behavior, and trigger dopamine neurons to begin stimulating behaviors.
Negative side effect associated with these drugs Side effects include sleepiness, weight gain, slowness, interference in your sex like, an increased chance of diabetes and Parkinsonism like side effects among others.

Anxiety Disorder: There are five major classes of anxiety disorders: generalized anxiety disorders, phobic anxiety disorders, panic disorders, obsessive-compulsive disorders, and post traumatic stress disorder (PTSD).

Changes in the activity of the dopamine system are associated with reduced motor skills and impaired verbal learning. Studies have also revealed that chronic use of methamphetamine causes severe structural and functional changes in those areas of the brain associated with emotion and memory, which could explain many of the
Nicotine works by attaching itself to receptors that bind the neurotransmitter called acetylcholine. Acetylcholine has many functions including sending signals to muscles, the beating of one’s heart, regulates the flow of information to the brain, and also plays a role in learning and memory. Since the body does not regulate nicotine, it affects many different regions throughout the brain simultaneously. It will lead to an increased release of acetylcholine,
Substance abuse can cause depression and depression can cause substance abuse. Stress is also associated with deficits in hippocampal functioning, the critical brain structure that inhibits stress reactivity and mediates contextual cues. Moreover, drug withdrawal leads to reduced hippocampal functioning via increased cortisol output (Keith, Roberts, Wiren, & Crabbe, 1995). Severity of declarative memory deficits
