Dr. Olney received
Academy’s
1996 Peter H.
Raven Lifetime
Award for neuroscience
research on
brain-damaging
properties of
glutamate and
its role in
neuro degenerative
diseases with
significant
implications
for treatment
of acute brain
disorders such
as stroke, trauma
and epilepsy.
Dr. Olney directs
a research program
that has been
supported continuously
for the past
three decades
by a Career
Research Scientist
Award from the
National Institute
of Mental Health.
Dr. Olney is
internationally
recognized for
his pioneering
research pertaining
to the actions
of glutamate
in the central
nervous system.
His early studies
helped establish
glutamate as
a major excitatory
transmitter
that is vitally
important for
normal brain
function, but
his discoveries
revealed that
glutamate is
also a neurotoxin
that can destroy
nerve cells
by excessive
stimulation
of their excitatory
receptors.
In the early
1970s, he coined
the term "excitotoxicity"
to refer to
the cell killing
action of glutamate
and he hypothesized
that glutamate
excitotoxicity
might play an
important role
in neurodegenerative
diseases. These
early insights
set the stage
for the subsequent
discovery that
acute brain
injury associated
with common
conditions such
as stroke, head
trauma and epilepsy
is triggered
by excessive
activation of
glutamate receptors.
Dr. Olney's
recent studies
are helping
to define a
role for glutamate
in chronic neuropsychiatric
disorders, including
Alzheimer's
disease and
schizophrenia.
His research
also focuses
on developmental
disorders of
the central
nervous system.
In the late
1960s, Dr. Olney
fed glutamate
to animals and
found that it
destroyed nerve
cells in the
brain. Because
infant animals
were especially
sensitive to
this neurotoxic
action, he undertook
a long battle
that eventually
resulted in
the food industry
ending its practice
of adding glutamate
to baby foods.
Much more recently,
he and his colleagues
have discovered
that the toxic
effects of alcohol
on the human
fetal brain
(fetal alcohol
syndrome) are
mediated by
a disruptive
effect of alcohol
on the glutamate
transmitter
system, a disruptive
effect that
causes developing
nerve cells
to commit suicide.
Dr. Olney has
published hundreds
of articles
in leading medical
journals, and
has won numerous
awards, including
the Wakeman
Award, Dana
Foundation Award
and Society
for Biological
Psychiatry Lifetime
Achievements
Award. Dr. Olney
is a member
of the Institute
of Medicine
of the National
Academy of Sciences.
