The origins of "modularity" in visual science
January, 1995
(seminar on visual perception held by Ilona KovVcs at Eptvps Lorand University,
Budapest)
The idea that the brain can be partitioned into more or less independent modules is one of
the basic assumptions of modern neuroscience. Modularity can be viewed as a useful
technical approach, and when it is not taken to the extremes, it helps scientist to define
problems clearly, and ask questions that can be tested experimentally. Modularity is
emphasized usually when the system under investigation seems to be very complex, and
without the isolation of its parts, understanding is difficult. Once the existence of the parts
is clarified, the interaction between them is the next question, and the system as a whole is
coming back to the picture. From this point of view, modularity is not a philosophical issue,
it is a natural way of the development of science.
VISUAL PSYCHOPHYSICS AND THE ORIGINS OF "MODULARITY"
My goal in selecting the papers for this textbook was to present an example of the birth of
modularity within a specific field. In vision, a single demonstration drew attention to the
fact that there are hidden capabilities in the brain to process raw perceptual information
quite independently from high level cognitive operations. Julesz's random-dot
stereograms proved that binocular disparity information in itself can be enough for us to
extract the three dimensional structure of the environment (see Julesz, 1964, 1965). The
demonstration defined the first clearly separable module of vision. As Julesz believed that
there must be other modular aspects of vision, and these should be treated separately
from the cognitive levels, he introduced the notion of "early vision". Early vision in the
strict sense was believed to be mediated by autonomous, fast, parallel processes of the
brain that are not penetrable for the higher cognitive levels. The approach was so fruitful
that it opened a literally new field of research. As the questions about binocular vision
could be now tested experimentally, not only psychologists, but physiologists too were
able to join the new trend. The modular approach also opens the field for modelers both in
the sense of constructing "vision machines" and in the sense of building a theory of vision.
Julesz was one the firsts to offer a computational model of stereoscopic vision, and later of
texture perception.
As the properties of the modules started to become clear, of course the questions about
their cooperation had to come up. That happened some 20 years after the discovery of
the random-dot stereograms (it took many years, because it turned out that those "simple"
input systems are, in fact, very complicated). Julesz was among the firsts to ask questions
about the role of attention in visual processing Bergen and Julesz, 1983; Sagi and Julesz,
1985). The function of visual attention in this context is to serve as a glue that binds
together the results of separated modules. And as coordination by attention and neural
interactions are gaining more and more emphasize, different puzzles open up for the
researchers and new concepts of modularity seem to be required (KovVcs and Julesz,
1994).
COMPUTATIONAL VISION
How did random-dot stereograms give rise to the field of computational vision? This
question is answered in Marr's introductory chapter (Marr, 1982). What are the tacit
assumptions underlying computational vision and what are the challenges that have been
raised against them (see Ullman, 1991)? What can computational vision accomplish so
far? An example, related to the modeling of biological vision is shown in Bergen and
Landy's (1991) paper.
NEUROPHYSIOLOGY
As vision seems to be one if those faculties of mind that we share in a large extent with
primates, it gives an exceptional opportunity for experimenters: human subjects can be
asked verbally about their experiences, and monkeys can take part in physiological
experiments, where the black box is being open. The results of these two different
paradigms can be combined because of the similarity between the visual systems of
humans and primates. We will see how did Poggio find the physiological correlates of
random-dot stereograms (Poggio, 1991).
An interesting extreme example of modularity is represented in Newsome et al's (1991)
paper, where they report that stimulation of a very small number of neurons by the means
of microelectrodes results in altered perceptual decisions, implying that a small bunch of
neurons is responsible for the given behavior.
I also included some recent findings about the architecture and interactions within the
primary visual cortex (Gilbert, 1993) that may serve to explain the psychopysically found
interactions (KovVcs and Julesz, 1994).
The last two papers (Niebur and Koch, 1994, Fregnac, 1991) are dealing with the
problems of integration and visual attention on a larger scale.
The reader might be familiar with some of the context represented in this textbook, it might
still be a hard task to thoroughly follow every articles since they come from diverse fields
within visual science. To help in understanding the basic terminology and conceptual
framework, I included a few chapters from a recent introductory Perception book (Sekuler
and Blake, 1994).

ABSTRACT: Drawing on previous models of anxiety, intermediate
memory, the positive symptoms of schizophrenia and goal-directed
behaviour, a neuropsychological hypothesis is proposed for the
generation of the contents of consciousness. It is suggested that
these correspond to the outputs of a comparator that, on a
moment-by-moment basis, compares the current state of the
organism's perceptual world with a predicted state. An outline is
given of the information-processing functions of the comparator
system and of the neural systems which mediate them. The
hypothesis appears to be able to account for a number of key
features of the contents of consciousness. However, it is argued
that neither this nor any existing comparable hypothesis is yet
able to explain why the brain should generate conscious experience
of any kind at all.
KEYWORDS: Conciousness, contents of consciousness, comparator,
septohippocampal system, anxiety, schizophrenia.
