Senior Seminar in Biology and Society

If you were depressed, what would you do?  Talk to a friend?  Tell a therapist?  Ask a psychiatrist for medication?  Learn meditation?  Begin practicing Buddhism?

All of these are normal reasonable responses to depression.  However, there are many more potential reactions based on religion, medicine, and individual preference.  Some are better researched, cheaper, safer, more private, or more socially acceptable in a given society.  It is beyond the scope of this paper to provide a complete list of treatment options and their relative merits.  The purpose of this work is to discuss one specific alternative remedy for depression, its neurobiological and psychological mechanism of action, horseback riding. 

In their book “Animals Make Us Human,” Temple Grandin and Catherine Johnson raise and attempt to answer the question: “what does an animal need to be happy?” (1).  They discuss the state of household pets, animals used in food production, and wildlife.  Their primary focus is the mental state of an animal inhabiting a human manipulated environment.  In order to measure an animal’s mental state, they assume a specific relationship between the brain and behavior.

“Who need be afraid of the merge?
Undrape… you are not guilty to me, nor stale nor discarded,
I see through broadcloth and gingham whether or no,
And am around, tenacious, acquisitive, tireless… and can never be shaken away.” (Whitman 26)

“Written on the [brain] is a secret code only visible in certain lights: the accumulations of a lifetime gather there. In places the palimpsest is so heavily worked that the letters feel like Braille.” (1)

In this paper, I would like to explore the origin of the writing on the human brain from a neurobiological perspective.  Neurobiology can provide us with information about the material nature of the brain.  After developing an understanding of the brain, I would like to consider the implications for learning and teaching.

“What would happen if you somehow came upon or created a dollop of universal acid? …  Little did I realize that in a few years I would encounter an idea-Darwin’s idea-bearing and unmistakable likeness to universal acid: it eats through just about everything traditional concept, and leaves in its wake a revolutionized world-view, with most old landmarks still recognizable, but transformed in fundamental ways.”  (Dennett 63)

The Brain Without Behavior

This paper is about exploring the relationship between the human brain and behavior.  To that end, I would like to explore the nervous system and behavior of paralyzed patients.  Paralysis is a condition in which portions of the body receive decreased or no direction from the nervous system.

In this course our first directions for reading Darwin’s book, On the Origin of Species, was to treat it as a novel.  Such instruction proved problematic for students, myself include, for a variety of reasons.  One reason is that reading a novel or enjoying any other work of art requires the reader to willingly suspend their disbelief.  In this paper, I would like to explore how the idea of willing suspension of disbelief is challenging to translate into studying a scientific text.

Book Commentary

The Schopenhauer Cure by Irving D. Yalom, chronicles the extraordinary last year of a therapy group.  Descriptions of the therapy sessions form a significant portion of the novel, complete with copious amounts of dialogue between group members.  These interactions are reported to the reader by the therapist, Julius Hertzfeld.  It is fascinating as the reader to witness the thoughts of therapist and consider how his own conscious and unconscious are responding to the patient.
