Australasian Science Prize Awarded for Insights on Nervous Transmission

Discovering insights into how sensory information is processed and
transmitted in the brain has earned Mark Rowe the Australasian Science Prize
for 2003, announced today.

Professor Rowe is the first medical scientist to win the Prize that rewards
outstanding research by individuals or small groups. Rowe is Emeritus
Scientia Professor and Conjoint Professor of Physiology at the University of
NSW. His colleague, Associate Professor John Carmody, describes him as
"Australia's most distinguished sensory neuroscientist. Few, if any,
laboratories can match the precision of his research, using a range of
mammalian species, notably the cat and marmoset monkey".

Precision is crucial when unravelling information from the thousands of
individual fibres that transmit sensations from a fingertip to the brain.
Each neuron (nerve cell) is 0.01-0.02 mm across. Nervous impulses sprint up
to 100 metres/second, taking 0.001 seconds to run along an arm or transfer
across any of the billions of synaptic junctions in the brain.

Rowe overturned the widely held view that nervous information, particularly
the sense of touch, is transmitted "serially" to the cortex of the brain
like a train passing from station to station. But by isolating sites in the
cerebral cortex through localised cooling, Rowe instead showed that
processing is "parallel", radiating like buses from a central hub.

Monash University Professor Uwe Proske says: "Mark Rowe discovered parallel
processing in the cortex, meaning that the brain acquires information about
the world with simultaneous use of several, separate networks. If we do not
have the information from all available channels our sensory experience is
compromised. 

"Rowe has been a pioneer in showing how Australia's native monotremes
provide unique models for studies in neuroscience. He was the first person
to map the region of the platypus brain that receives information coming
from nerve endings in the bill. Recent papers report findings on their sense
of touch."

The National Health & Medical Research Council and the Australian Research
Council have supported Rowe's research continuously over nearly 20 years
with a total of $2.8 million since 1989.

While Rowe is cautious about predicting practical application of his work,
which he sees as "fundamental in the best spirit of scientific inquiry",
Carmody believes: "These findings have implications for understanding
disturbances of consciousness and perception that characterise some
psychiatric disorders, most notably schizophrenia".

GRAPHICS and a PHOTOMICROGRAPH explaining Rowe's experiments and findings
and a photo of him recording faint signals from individual neurons are
available.
