The Neuron and Drugs Create 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 be thoroughly 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, make your 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 involves uploading either 1 or 2 files to complete this assignment. Remember to save and submit your file(s) in PDF file format. Neurotransmitters and Drugs
There are several different types of neurotransmitters released by different neurons, and we 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 perspective and focus on the physiological causes of behavior assert that psychological disorders like depression and schizophrenia 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 medications are drugs that treat psychiatric symptoms by restoring neurotransmitter balance. Major Neurotransmitters and How They Affect Behavior Neurotransmitter Involved in Potential Effect on Behavior Acetylcholine Muscle action, memory Increased arousal, enhanced cognition Beta-endorphin Pain, pleasure Decreased anxiety, decreased tension Dopamine Mood, sleep, learning Increased pleasure, suppressed appetite Gamma-aminobutyric acid (GABA) Brain function, sleep Decreased anxiety, decreased tension Glutamate Memory, learning Increased learning, enhanced memory Norepinephrine Heart, intestines, alertness Increased arousal, suppressed appetite Serotonin Mood, sleep Modulated mood, suppressed appetite Table3.1 Psychoactive drugs can act as agonists or antagonists for a given neurotransmitter system. Agonists are chemicals that mimic a neurotransmitter at the receptor site.
