Pollard Directs Internal Medicine Course

Study Communications Systems:
(Continued from Page 2)

Prof. H. Marvin Pollard of the
Medical School was general co-
ordinator of a five-day course on
postgraduate internal medicine at
the University of Antioquia in
Medellin, Colombia.
The March 8-12 program was
held in collaboration with the
American College of Physicians.
Also participating was Prof. Stef-
an S. Fajans of the Medical
School.
* * *
Prof. Mary C. Bromage of the
business administration school
conducted a two-day report-writ-
ing seminar recently in Atlanta,
Ga., for the United States Audit
Agency. Attending were 17 parti-
cipants representing Army Audil
Agency offices in Boston, Phila-
delphia, New York, Washington,
and Atlanta.,

half of the program in Hill Aud.

A second model was also formu-
lated, based on a checker board
system. A primary automaton was
set up in part of the checker
board and a second was to be re-
produced through transference of
information through the squares.
Von Neumann used 28 different
states of excitation, plus a special
state of no excitation in his
theory. On a computer these
would be variations of electrical
pulses.
This makes it possible to study
what information has to be trans-
ferred from square to square in
order for reproduction to take
place.

cal elements of words vary with
their pronunciation both by the

The tone of voice, dialect, dif-
ferent physiological production of
esent word sounds, the emphasis given
to diffelrent parts of the word, and.
the voice frequency itself-all can
change the acoustical parameters
of the input wave and make it dif-
ficult if not impossible for the
computer to make a "recognition."
Peterson suggests the possibility
of the storage of a large range of
possible values of the parameters
for the same word might help
solve this problem. He also feels
that by limiting the scope of the
computer input recognition might
be easier.
Inverse Proposition
As vocabulary is decreased, dia-
lectal range may be increased, he
explains.

TOMOJI YANAGITA of the pharmacology department of the Medical School is shown working with
the models of excitable heart cells. They were designed by -Prof. Henry H. Swain of the Medical
School in order to study fibrillation. The graph in the background shows the distribution of re-
sponse of all five units to a series of stimuli delivered during the relative refractory period. When
sufficient delay of conduction through the units accumulates the fifth unit is able to restimulate the
first unit. This establishes the fibrillation rhythm.

Communication Breakdown
Prof. Henry H. Swain of the
Medical School is researching a
theory that explains fibrillation-
random action of the heart cells-
as a breakdown of heart cell com-
munication. "Heart cells have no
insulation," he explains.

"Stimulate the heart at any
point and its cells will all respond
at the same time. Simultaneous
firing allows the cells to enter 6
refractory period, when they can
not fire, at the same time. In this
way a constant rhythmic pulsation
is maintained.
Heart Control ,
This simultaneous communica-
tion enables a group of "pace-
maker" cells, which fire faster
than most of the heart cells, to
control the heart, Swain explains.
"Fibrillation is a breakdown oY
this communication. The heart
beat starts out normally, but
something happens and the or;
derly sequence - fire, refractory,
fire-is replaced by randpm activ-
ity. Some cells fire while others
remain in their refractory period.
The result is a continuous, dis-
organized firing of the cells," he
says.
In order to study this phenome-
non, which Swain terms "circus
rhythm," he has used an electron-
ic model of five excitable cells.
No Interferring Properties
"The reason for making the
model," Swain says, "is that it can
be constructed to follow any be-
havioral pattern and has no inter-
fering properties itself. This is ar
advantage because, in biological
systems, things are occurring si-
multaneously, and it is very easy
to assume a causal relationship
among them."
Swain has found that he can
duplicate the regular rhythmic
firing of the cells as well as thie
"circus rhythm" characteristic of
fibrillation. Performance of the
model suggests that thet length of
time a cell takes to conduct stim-
uli to the next cell may be related
to fibrillation, which is self}
perpetuating.
