Innate or learned behavioural responses can be observed in a neural representation of the sensory world. Naïve animals, which are without prior learning or experience, show an innate response to a sensory stimulus suggesting that they are mediated by genetically determined neural circuits. Most sensory stimuli, however, show an experience-dependent response, allowing an organism to respond appropriately in a variable and uncertain world. Thus, behav-ioural relevance to sensory cues is mostly acquired through learning. In Drosophila melanogaster, different forms of learning have been observed in response to a number of sensory stimuli. The mushroom body (MB), in insects, is responsible for memory formation and retrieval.
When an olfactory

Most antennal lobe projection neurons (PNs) extend their dendrites to a single glo¬merulus while their axons bifurcate to innervate the lateral horn and the MB of the brain. The lateral horn is thought to mediate innate behaviours, whereas the MB translates olfactory sensory information into learned behavioural responses. On the activation from an odorant, PN axons synapse onto the den¬drites of the Kenyon cells (KCs) in the MB calyx. According to anatomical and physiological studies, each KC is said to receive, on an average, 6.4 inputs from a random combination of glo¬meruli which indicates that knowledge of a single input to the KC cannot provide information about all the additional inputs and these connections differ in different flies.
The γ, α′/β′, and α/β lobes of the MB are formed from three classes of KCs that extend their parallel fibers to these lobes and form synapses with a relatively small number of MB output neurons (MBONs). The MBONs extend their dendrites into the MB lobes, while their axons are projected to the neuropils which lie outside the MB. Modulatory input neurons which include the dopaminergic neurons (DANs) and octo¬paminergic neurons, also innervate the MB lobes. The MBONs and DANs extend their processes to locations such that they define spatially restricted ‘subdomains’ in each lobe.
DANs are modulatory neurons of the MB that are most prevalent.
While many obstacles get in the way of friendship, true friendship still lives, even in silence. In the book, The Chosen , By Chaim Potok, two boys, Reuven Malter and Danny Saunders, who are very religiously different and both raised in completely opposite ways, develops a deep friendship. Their friendship opens up their worldview to many other different viewpoints in life. The friendship between these two boys is one with great religious significance, starting off with destiny and Gods will. As Danny and Reuven’s Friendship develops, it teaches them to respond wisely to the values of the more complex and secular world. It also teaches the true value of friendship. Because Danny’s father, Reb
1. The nation is at war, and your number in the recently reinstated military draft has just come up. The problem is that, after serious reflection, you have concluded that the war is unjust. What advice might Socrates give you? Would you agree? What might you decide to do? Read the Introduction, Chapter 2 Crito and the Conclusion Chapter 40 Phaedo by Plato.
Matt Lamkin’s “A Ban On Brain-Boosting Drugs is Not the Answer” first appeared in Chronicle of Higher Education in 2011. In this essay Lamkin aims to convince his reader not to deter improper conduct with threats, but to encourage students to engage in the practice of education. Lamkin tells us “If colleges believe that enhancing cognition with drugs deprives students of the true value of education, they must encourage students to adapt that value as their own” (642). Appeal to logic, consistency, and compare/contrast are techniques Lamkin skillfully uses to create a strong effective essay.
Dana and Rufus might look like friends from the outside, but Dana’s feelings for him are quite different from what we think of them. To begin with Dana sees Rufus as a child needing or relying upon her protection. For instance, when Dana saved him from drowning in the river. Secondly, she views him as a man of his time. In another words Rufus’s personality is the way that any other man would have been in that period of time towards his slaves. Lastly, he is a ruthless and vicious slaveholder, which Tom Weylin’s fault. Just as Tom’s behaviour on the slaves and on his son. Finally, I will explain in more details how Dana’s feelings for Rufus are in the following
As with playing the “What If” game (asking “what if” incessantly to explore each aspect of a situation), so did a chain of events occur that caused this relationship to form.
In the biography Unbroken, by Laura Hillenbrand, a troubled adolescent boy named Louis Zamperini revolves his life around his running career. Starting at such a young age, running had many impacts on Louie’s life. The high demand of training kept Louie distracted from making unintelligent choices he had previously been making. Running changed the young teenager he was and the man he was going to become.
The cell body comprises of the nucleus and other organelles (Ward, 2010). The nucleus contains the genetic code, and this is involved with protein synthesis (He, 2013). The dendrites receive information from other neurons which are located in a close proximity (Kalat, 1995). The terminal of an axon compresses into a disc-shaped structure (Gross, 2010). This is where chemical signals also known as a neurotransmitter permit interaction amongst neurons, by means of a minute gap named a synapse (Martin, Carlson & Buskit, 2013). Both neurons which form the synapse are referred to as a presynaptic synapse (prior to the synapse) and postsynaptic (after the synapse), reflecting the direction of information flow (from axon to dendrite), (He, 2013).
The NARAL was founded originally as the The National Association for the Repeal of Abortion Law in 1969.The headquarters for the organization is based in none other than Washington D.C. It is a pro-choice group.(live-action) Meaning that they protect the rights of women to have reproductive rights, this is women who feel the need to have an abortion for their own reasons. “Any woman should be able to decide if,when, how and with whom they shall start a family”. They always support the need of making birth control available to those who want it, thus including making it cost efficient and is covered by insurances. It educates women on the facts about abortion and sex, and believes that the government should required sex-ed classes to
1. Eighner organizes his essay by breaking down how and why scavengers do what they do to survive. He begins his essay with how he became a scavenger and follows that with how to scavenge the best, safest way possible. He communicates how to choose the right dumpsters to dive into, how to determine if food is edible, and whether items are worth holding onto. I believe Eighner chose this type of organization throughout his essay to ease readers into the idea of scavenging through dumpsters. I feel like Eighner is almost trying to convince reader that’s scavenging through dumpster is not that bad, so if he shed the activities in a positive
“Roy, will you be the best there ever was in the game?” “That’s right.” (p.33) In The Natural, by Bernard Malamud, Roy Hobbs intends to be the best baseball player there ever was, breaking all of the records and enjoying the fame that came with it. He started playing for the Knights under the management of Pop Fisher as a rookie at the age of 34. His career started slowly but eventually he became the most liked and most watched player in all of baseball leading his team from last place in the standings to the best team in baseball. In 1984, Mark Johnson took the book and produced it into a movie. While there were plenty of small differences, a few major changes were made. These changes ultimately led us from the book where we didn’t like
The book Challenger Deep is a fiction book, but at the same time, a nonfiction book that talks about mental health issues. The author, Neal Shusterman, explains at the end of the book that his story was based on what his relatives have dealt with when it came to their mental illness. Neal writes about his experience supporting his son, his family, and closest friend during their descent into their mental illness. The main character of this book is Caden Bosch as he goes throughout his descent into his mental illness by portraying it as a ship at sea.
The doctor-patient relationship always has been and will remain an essential basis of care, in which high quality information is gathered and procedures are made as well as provided. This relationship is a critical foundation to medical ethics that all doctors should attempt to follow and live by. Patients must also have confidence in their physicians to trust the solutions and work around created to counter act certain illnesses and disease. Doctor-patient relationships can directly be observed in both the stories and poems of Dr. William Carlos Williams as well as in the clinical tales of Dr. Oliver Sacks. Both of these doctors have very similar and diverse relationships with multiple patients
Timeliness is crucial to attracting customers in this field, because from the Thoughtworks text, we know that:
Throughout the passage of time, philosophers have written and discussed many topics in philosophy. Sometimes, these philosophers agree on ideas or sometimes they make their own assumptions. There are two philosophers who had different ideas concerning where innate ideas come from and how we get these types of ideas. Rene Descartes and John Locke were these two philosophers with the opposing argument on innate ideas. The place where Descartes discusses his views were in the Meditations on First Philosophy and Locke's argument is located in An Essay Concerning Human Understanding. By using these sources I will be able to describe the difference between these two arguments on innate ideas.
In the book Mind Hunter, author, John Douglas introduces how the FBI provides learning, education and techniques throughout Local, State and Federal police. John Douglas was a former FBI agent from the FBI at Quantico, VA. Douglas tells about how he and a team of FBI officers formed the Investigative Support Unit. Douglas explains the steps and techniques used in profiling an offender, by putting himself inside the mind of a killer and victim. Douglas has interviews with famous serial killers in prison. Douglas learned a lot about what was going on inside the killer’s mind, with clues he left at a crime scene.
