Short Answer: Explain the Cholinergic Hypothesis and how it is involved with treating neurological disorders.
The cholinergic hypothesis states that Acetylcholine (ACh) is an important neurotransmitter in areas of the brain involved in memory formation and that loss of ACh activity correlates with the severity of Alzheimer’s Disease. This explains how cholinergic replacement and Acetylcholinesterase Inhibitors can treat Alzheimer’s disease. Acetylcholinesterase Inhibitors block esterase-mediated metabolism of acetylcholine to choline and acetate, so that there is increased ACh in the synaptic cleft.

b. Distorted perception of a real odor
Short answer: Describe the difference between innate immunity and adaptive immunity. Choose either Innate or Adaptive immunity and explain the responses used and how these responses work.
Innate immunity occurs in all animals. It is nonspecific, inherited, and rapid. It involves recognition of traits shared by broad ranges of pathogens, using a small set of receptors. Adaptive immunity is specific, adaptive and slower, and occurs only in vertebrates. It includes recognition of traits specific to particular pathogens, using a vast array of receptors. Innate immunity begins with barrier defenses. For example, mucus traps and allows for the removal of microbes. Lysozymes in saliva, mucus and tears can destroy bacteria. The low pH of skin prevents growth of bacteria. Internal defenses include phagocytic cells, natural killer cells, antimicrobial proteins, and inflammatory responses. Phagocytic cells destroy pathogens by engulfing them and fusing with a lysosome, then releasing the debris. Antimicrobial proteins enter tissue when histamine and cytokines are released. Then Neutrophils are recruited which digest the pathogens and allows tissue to heal.

Short answer: Explain how Pick’s disease and Fronto-Temporal Dementia differ.
Answer: Pick’s disease is a specific subtype of FTD, characterized by the presence of abnormal brain cells known as Pick bodies and Pick cells. It mainly affects the frontal and temporal lobes, like FTD, and typically presents symptoms similar to the behavioral variant FTD. FTD itself is an umbrella term that encompasses several types of dementia, including Pick’s disease.

Short Answer: Describe the two ways in which emotions can be induced
The two ways in which emoticons can be induced are through primary induction and secondary induction. In primary induction, emotion is evoked when the individual is confronted by a stimulus/stimuli that is either innate or learned to be pleasurable or aversive. On the other hand, with secondary induction emotion is evoked when the individual thinks about or reflects on a memory including those stimuli.
Which is the trigger structure for secondary induction emotions?
a. Hippocampus
b. Amygdala
c. Orbito/ventromedial prefrontal cortex
d. Thalamus
c. Orbito/ventromedial prefrontal cortex
