Masao Ito and Roger Nicoll
Win International Neuroscience Prize

The
secrets of memory
Atlanta, Oct. 15, 2006
How do we learn? How do we remember?
Two neuroscientists – whose work is answering
these questions – will be honored today with the $250,000
Gruber Prize for Neuroscience.
“Professor Masao Ito from the Rikin Institute
in Japan, and Professor Roger Nicoll from the University of
California, San Francisco, have together provided the keys to
our understanding of the molecular and cellular bases of learning
and memory,” says Peter Gruber, President of the Peter
Gruber Foundation.
Professor Ito, special advisor to the RIKEN
Brain Science Institute in Japan, and Professor Nicoll, Professor
of Cellular and Molecular Pharmacology at the University of
California, San Francisco, will receive their awards at Neuroscience
2006, the annual conference of the Society for Neuroscience,
held this year in Atlanta, Georgia. Each will receive a gold
medal and a $125,000 cash prize.
They will jointly present the Peter Gruber
Lecture entitled, Brain learns with molecules and circuitry.

Ito and Nicoll have been shining light on the
complex workings of the brain for the past four decades. Both
men worked with and have built on the achievements of Nobel
Laureate John Eccles.
They are the third recipients of the Neuroscience
Prize of the Peter Gruber Foundation, which is awarded annually
to honor the most distinguished work in the field of the brain,
nervous system and the spinal cord.
What is memory? In one of many research contributions,
Ito showed how motor learning (subconscious memory of procedures
like driving) might function in the cerebellum. His team has
identified over 30 molecules involved in these processes.
Nicoll has shown how episodic memory (such
as memory of personal emotions and associations with a particular
place) might be stored in the hippocampus.
These and many other discoveries have opened
up new fields of study for neuroscience.
“The work of Nicoll and Ito is teaching
us how our brains work at a molecular level. Once we understand
the chemistry of thought we may then be able to design better
drugs to deal with Alzheimer’s and other degenerative
diseases of the brain,” says Peter Gruber.
About the Foundation
The Peter Gruber Foundation was founded in
1993 and established the first of its international prizes in
2000. The Foundation now supports five international awards:
Cosmology; Genetics, Neuroscience; Justice and Women’s
Rights.
The 2006 Cosmology Prize was presented in August
to NASA’s John Mather. Last week it was announced that
he will share the 2006 Nobel Prize in Physics. The Justice Prize
was awarded in September to Aharon Barak, recently retired President
of the Supreme Court of Israel. The Genetics Prizes was awarded
last Tuesday to Elizabeth Blackburn for her work on cell aging
and telomeres. The Women’s Rights Prize will be presented
in New York next month.
Background: The
2006 Neuroscience Prize
The Neuroscience Prize honors the most distinguished work in
the field of the brain, nervous system and the spinal cord.
The official citation reads:
“The 2006 Neuroscience Prize of the
Peter Gruber Foundation is hereby proudly presented to Dr. Masao
Ito, RIKEN, and Dr. Roger Nicoll, University of California,
San Francisco, whose studies provided the keys for our understanding
of the molecular and cellular bases of learning and memory.
The Foundation recognizes the pioneering
work of Dr. Ito concerning the role of the cerebellum in motor
learning and the overall organization of neuronal circuitry
involving network and cellular mechanisms for changing synaptic
strength, and the outstanding contribution of Dr. Nicoll’s
work on the hippocampus as a cellular model for the formation
of episodic memory and, in particular, the molecular and cell
biological mechanisms underlying changes in synaptic efficacy.
In a global perspective, Drs. Ito and Nicoll
have contributed importantly, over many decades, to furthering
neuroscience at all levels, from molecular and cellular to the
circuit level, as well as to the training of a new generation
of outstanding neuroscientists”.
Past Winners of the Neuroscience
Prize
Following the award presentation Masao Ito
and Roger Nicoll will jointly present the 2006 Gruber Lecture:
Brain Learns with Molecules and Circuitry.
The abstract reads: A general consensus has
emerged that information storage in the brain involves persistent
changes in synaptic strength that, in turn, modify local circuit
behavior.
Roger Nicoll will focus on the cellular and
molecular substrates for explicit learning and memory. The hippocampus
is critical for this form of memory. In this structure, activity-dependent
long-term potentiation (LTP) of excitatory synapses is proposed
to play a critical role. Recent work from many labs suggests
that LTP is due to the rapid insertion of glutamate receptors
into the synapse. The molecular machines involved in long-term
depression (LTD) and LTP share similarities and differences.
Masao Ito will discuss long term depression
(LTD) of excitatory synapses occurring in cerebellar Purkinje
cells as a memory process. While complex processes involving
more than 30 different molecules underlie LTD, the molecular
machines involved in LTD and LTP share similarities and differences.
LTD gives rise to a mechanism for the cerebellar circuitry to
form internal models that serve a broad range of implicit learning
mechanisms.
