on a total of 100 poimts. The exam as open choice). The final exam score will be based however, you are on your honor to not consult anyone else Essay Questions (10 points each, total 40 points) Answer each question as fully as possible As specified for each question, you need only the required chapters/videos/websites for the answers-you are not required to use any additional information beyond the course material. You are free to add other resources, as long as you cite and reference them in APA-style, but this is completely optional What are neurotransmitters, and how can they cause an action potential? For this answer, think about some of the concepts and terms from Week 2: receptors, ion channels, EPSPs/ISPSs, summation, threshold of excitation, and more! Historically, a significant controversy in the field of biopsychology was the question of how our behavior is a result of nature (biology, genetics, inheritance) or a result of nurture (the environment we grow up in). Today, this is an obsolete position and it is believed by most that there is an interaction among genetics/biology and environment (or experience). The more accurate position is that behavior is due to an interaction between genetics/biology and experience. Discuss this statement, citing relevant experimental evidence, in the context of at least one psychological behavior or disorder For example, you could discuss visual perception, birdsong communication, learning, intelligence, aggression, obesity, mental disorders (anxiety attention deficit hyperactivity disorder, depression, etc.), or another topic of interest to you WORDSExplanation / Answer
Neurotransmitters are the chemicals that are involved in the transmission of nerve impulses at synapses. (A synapse is formed by the membranes of a pre synaptic neuron and post synaptic neuron.)
Neurotransmitters provide the stimulus at a site (let that site be site A ), now that membrane of a neuron becomes freely permeable to Na+. This leads to a rapid influx of Na+ . Now the inner surface of membrane becomes positively charged and outer surface is negatively charged. Now we say that membrane is depolarized. the electrical potential difference across the plasma membrane at the site A is called action potential. Hence as the stimulus is provided by neurotransmitters so we can say they cause action potential.
Behavior is due to interaction due to genetics/biology and experience. Let us take the example of intelligence. Intelligence of child is similar to that of his/her parents because of genetic factor. But while growing his intelligence is affected by his/her experience. There is interaction between his/her genes and experiences which combinedly decides the child's intelligence. If a child is born with low IQ but has experiences in constructive way then his/her intelligence increases and if child is born with high IQ but has experiences in destructive way then his intelligence decreases. So there is interaction between genetics and experience towards human behaviour.
