The Neuron and DrugsCreate a likeness or model of a neuron (recreate "prototypical neuron" from Figure 3.8/p. 84) out of string, wire, pipe cleaners, chenilles, twine, etc. If you make this just a drawing it needs to be drawn freehand in multiple colors instead of copied, plus it should bethoroughly labeled. If you make it with some of this other material, find a creative way to label at least the three main parts of the neuron. Make sure you have all the nerve parts clearly visible. Take a close up picture (selfie) of you holding the likeness you created and upload it here on the assignment link or include it in the following paper. If you do not have access to a digital camera, makeyour creation and see if a friend will take the picture and send it to your email. (50 Points)Next, write 2-4 paragraphs describing how 2 different types of psychoactive drugs (stimulants, depressants, hallucinogens, etc.) are processed by neurons in the brain. (40 points)Spelling and grammar (10 Points)This assignment has 2 parts (Likeness and paragraphs) and involvesuploading either 1 or 2 files to complete this assignment. Rememberto save and submit your file(s) in PDF file format.Neurotransmitters and Drugs
There are several different types of neurotransmitters released by different neurons, andwe can speak in broad terms about the kinds of functions associated with different neurotransmitters (Table 3.1). Much of what psychologists know about the functions of neurotransmitters comes from research on the effects of drugs in psychological disorders. Psychologists who take a biological perspectiveand focus on the physiological causes of behavior assert that psychological disorders like depression andschizophrenia are associated with imbalances in one or more neurotransmitter systems. In this perspective, psychotropic medications can help improve the symptoms associated with these disorders. Psychotropic medicationsare drugs that treat psychiatric symptoms by restoring neurotransmitter balance.Major Neurotransmitters and How They Affect BehaviorNeurotransmitterInvolved inPotential Effect on BehaviorAcetylcholineMuscle action, memoryIncreased arousal, enhanced cognitionBeta-endorphinPain, pleasureDecreased anxiety, decreased tensionDopamineMood, sleep, learningIncreased pleasure, suppressed appetiteGamma-aminobutyric acid (GABA)Brain function, sleepDecreased anxiety, decreased tensionGlutamateMemory, learningIncreased learning, enhanced memoryNorepinephrineHeart, intestines, alertnessIncreased arousal, suppressed appetiteSerotoninMood, sleepModulated mood, suppressed appetiteTable3.1Psychoactive drugs can act as agonists or antagonists for a given neurotransmitter system. Agonistsare chemicals that mimic a neurotransmitter at the receptor site.
