Course Description
This course will review the basic principles of neural plasticity with special emphasis on cortical plasticity related to development, recovery from injury and learning.
Lectures will provide students with the appropriate background for each topic, and discussions will explore classic and modern primary papers. Workload will consist of readings, class presentations, class participation, and weekly written critiques.
This first aim of the course is to provide a detailed and up-to-date understanding of the concepts and methods involved in a well-studied aspect of brain function: plasticity. The focused nature of this course will be a useful supplement to a general education of brain function based on surveys of many fields. Because similar plasticity principles apply throughout the brain the detailed description of cortical plasticity provided by this course will serve as a conceptual starting point for thinking about other brain regions. An additional aim of this course is to relate the discussed concepts to clinically relevant issues. This course assumes only a general understanding of basic neuroscience principles and will be useful to students interested in neuroscience, communication disorders, cognitive science, developmental psychology, biology, computer science, or neural networks. It is recommended that students have taken Cellular Neuroscience and Integrative Neuroscience.
Material Discussed
Concepts:
· Developmental plasticity
· Pathological plasticity
· Plasticity induced by peripheral injury
· Plasticity induced by central injury
Techniques/Approaches:
Course Requirements
All assigned readings must be completed before each class.
Critiques – 20% of final grade.
Each week you will need to email a concise, thoughtful critique of one of the papers for discussion. Support your conclusions using concrete evidence and quotations, not merely your opinion. The following outline is suggested: (1) Summarize in 1-2 sentences the key take-home message(s) of the paper. (2) Place the paper in context within the literature we have covered in class. What central problems does it address? How does it differ from other work we studied? How does it advance the field? (3) Critique the methods and conclusions. Are there any flaws in technique or logic? Are the experiments or conclusions believable? (4) Discuss the paper in terms of key concepts we have covered in class. (5) Suggest improvements or additional work. What important related questions does the paper leave open? Critique assignments should be about a page long and should be on the primary research papers not the review articles.
Individual class participation – 50% of final grade
In class presentation – 20% of final grade.

Student
Conduct & Discipline The University of Texas System and The
University of Texas at Dallas have rules and regulations for the orderly and
efficient conduct of their business. It is the responsibility of each
student and each student organization to be knowledgeable about the rules and
regulations which govern student conduct and activities. General
information on student conduct and discipline is contained in the UTD
publication, A to Z Guide, which is provided to all registered students
each academic year.
The
University of Texas at Dallas administers student discipline within the
procedures of recognized and established due process. Procedures are
defined and described in the Rules and Regulations, Board of Regents, The
University of Texas System, Part 1, Chapter VI, Section 3, and in Title V,
Rules on Student Services and Activities of the university’s Handbook of
Operating Procedures. Copies of these rules and regulations are
available to students in the Office of the Dean of Students, where staff
members are available to assist students in interpreting the rules and
regulations (SU 1.602, 972/883-6391).
A
student at the university neither loses the rights nor escapes the
responsibilities of citizenship. He or she is expected to obey federal,
state, and local laws as well as the Regents’ Rules, university regulations,
and administrative rules. Students are subject to discipline for
violating the standards of conduct whether such conduct takes place on or off
campus, or whether civil or criminal penalties are also imposed for such
conduct.
Academic
Integrity The
faculty expects from its students a high level of responsibility and academic
honesty. Because the value of an academic degree depends upon the
absolute integrity of the work done by the student for that degree, it is
imperative that a student demonstrate a high standard of individual honor in
his or her scholastic work.
Scholastic
dishonesty includes, but is not limited to, statements, acts or omissions
related to applications for enrollment or the award of a degree, and/or the
submission as one’s own work or material that is not one’s own. As a
general rule, scholastic dishonesty involves one of the following acts:
cheating, plagiarism, collusion and/or falsifying academic records.
Students suspected of academic dishonesty are subject to disciplinary
proceedings.
Plagiarism,
especially from the web, from portions of papers for other classes, and from
any other source is unacceptable and will be dealt with under the university’s
policy on plagiarism (see general catalog for details). This course will
use the resources of turnitin.com, which searches the web for possible
plagiarism and is over 90% effective.
Email
Use
The University of Texas at Dallas recognizes the value and efficiency of
communication between faculty/staff and students through electronic mail. At
the same time, email raises some issues concerning security and the identity of
each individual in an email exchange. The university encourages all
official student email correspondence be sent only to a student’s U.T. Dallas
email address and that faculty and staff consider email from students official
only if it originates from a UTD student account. This allows the university to
maintain a high degree of confidence in the identity of all individual
corresponding and the security of the transmitted information. UTD
furnishes each student with a free email account that is to be used in all
communication with university personnel. The Department of Information
Resources at U.T. Dallas provides a method for students to have their U.T.
Dallas mail forwarded to other accounts.
Withdrawal
from Class The
administration of this institution has set deadlines for withdrawal of any
college-level courses. These dates and times are published in that semester's
course catalog. Administration procedures must be followed. It is the student's
responsibility to handle withdrawal requirements from any class. In other
words, I cannot drop or withdraw any student. You must do the proper paperwork
to ensure that you will not receive a final grade of "F" in a course
if you choose not to attend the class once you are enrolled.
Student
Grievance Procedures Procedures for student grievances are
found in Title V, Rules on Student Services and Activities, of the university’s
Handbook of Operating Procedures. In attempting to resolve any
student grievance regarding grades, evaluations, or other fulfillments of
academic responsibility, it is the obligation of the student first to make a
serious effort to resolve the matter with the instructor, supervisor,
administrator, or committee with whom the grievance originates (hereafter
called “the respondent”). Individual faculty members retain primary
responsibility for assigning grades and evaluations. If the matter cannot
be resolved at that level, the grievance must be submitted in writing to the
respondent with a copy of the respondent’s School Dean. If the matter is
not resolved by the written response provided by the respondent, the student
may submit a written appeal to the School Dean. If the grievance is not
resolved by the School Dean’s decision, the student may make a written appeal
to the Dean of Graduate or Undergraduate Education, and the deal will appoint
and convene an Academic Appeals Panel. The decision of the Academic
Appeals Panel is final. The results of the academic appeals process will
be distributed to all involved parties. Copies of these rules and
regulations are available to students in the Office of the Dean of Students,
where staff members are available to assist students in interpreting the rules
and regulations.
Incomplete
Grade Policy As
per university policy, incomplete grades will be granted only for work
unavoidably missed at the semester’s end and only if 70% of the course work has
been completed. An incomplete grade must be resolved within eight (8)
weeks from the first day of the subsequent long semester. If the required
work to complete the course and to remove the incomplete grade is not submitted
by the specified deadline, the incomplete grade is changed automatically to a
grade of F.
Disability
Services The
goal of Disability Services is to provide students with disabilities
educational opportunities equal to those of their non-disabled peers.
Disability Services is located in room 1.610 in the Student Union. Office
hours are Monday and Thursday, 8:30 a.m. to 6:30 p.m.; Tuesday and Wednesday,
8:30 a.m. to 7:30 p.m.; and Friday, 8:30 a.m. to 5:30 p.m. The contact
information for the Office of Disability Services is: The University of Texas
at Dallas, SU 22 PO Box 830688 Richardson,
Texas 75083-0688 (972) 883-2098 (voice or TTY)
Essentially,
the law requires that colleges and universities make those reasonable
adjustments necessary to eliminate discrimination on the basis of
disability. For example, it may be necessary to remove classroom
prohibitions against tape recorders or animals (in the case of dog guides) for
students who are blind. Occasionally an assignment requirement may be
substituted (for example, a research paper versus an oral presentation for a
student who is hearing impaired). Classes enrolled students with mobility
impairments may have to be rescheduled in accessible facilities. The
college or university may need to provide special services such as
registration, note-taking, or mobility assistance.
It
is the student’s responsibility to notify his or her professors of the need for
such an accommodation. Disability Services provides students with letters
to present to faculty members to verify that the student has a disability and
needs accommodations. Individuals requiring special accommodation should
contact the professor after class or during office hours.
Religious
Holy Days
The University of Texas at Dallas will excuse a student from class or other
required activities for the travel to and observance of a religious holy day
for a religion whose places of worship are exempt from property tax under
Section 11.20, Tax Code, Texas Code Annotated.
The
student is encouraged to notify the instructor or activity sponsor as soon as
possible regarding the absence, preferably in advance of the assignment.
The student, so excused, will be allowed to take the exam or complete the
assignment within a reasonable time after the absence: a period equal to the
length of the absence, up to a maximum of one week. A student who notifies the
instructor and completes any missed exam or assignment may not be penalized for
the absence. A student who fails to complete the exam or assignment within the
prescribed period may receive a failing grade for that exam or assignment.
If
a student or an instructor disagrees about the nature of the absence [i.e., for
the purpose of observing a religious holy day] or if there is similar
disagreement about whether the student has been given a reasonable time to
complete any missed assignments or examinations, either the student or the
instructor may request a ruling from the chief executive officer of the
institution, or his or her designee. The chief executive officer or designee
must take into account the legislative intent of TEC 51.911(b), and the student
and instructor will abide by the decision of the chief executive officer or
designee.
These descriptions and timelines are
subject to change at the discretion of the Professor.
