USING EYE MOVEMENTS TO PROBE BRAIN FUNCTION AND DYSFUNCTION

Saccadic eye movements are controlled by a network of brain areas that
span 
frontal and parietal cortices, basal ganglia, thalamus, midbrain,
brainstem, 
and cerebellum. Thus, the eye movement system provides an excellent
model to 
probe normal brain function and development, as well as dysfunction that

arises in a variety of neurological and psychiatric disorders. In this
talk, 
MUNOZ will discuss results from monkey neurophysiology experiments,
human 
functional imaging experiments, and behavioural experiments involving 
various patient groups to show how the eye movement system can be used
as a 
tool to study brain function and dysfunction.  The talk will focus on
the 
use of the anti-saccade task as an experimental tool because this task 
requires voluntary control over the eye movement system and provides a 
measure of impulse control.  Monkey neurophysiological experiments are
used 
to identify critical elements in the neural circuitry required to
perform 
the task correctly. Functional brain imaging experiments are used to 
identify critical elements of the circuit in normal humans. Finally,
studies 
of patient groups, especially attention-deficit hyperactivity disorder,
are 
used to reveal how task performance is compromised when part of the
network 
is dysfunctional.
