Marie Curie Postdoctoral research opportunity in insect vision

University of London

We are seeking candidates who are internationally competitive, taking into
account the current stage of their career. The strongest candidates may be
offered a short term departmental fellowship during which time they would be
expected to seek external funding from the Marie Curie postdoctoral
programme for up to 2 years. We will provide other candidates with help in
applying for appropriate fellowships that can be hosted at QMUL.  The
deadline for submitting applications to the Marie Curie programme is 18
August 2010, so please contact Prof Lars Chittka asap if you should be
interested at:l.chittka at qmul.ac.uk.

PROJECT TITLE: Hyperacuity in the insect visual system - bumblebees as a
model

Supervisors: Lars Chittka, Peter Skorupski (Queen Mary University of
London); Johannes Zanker (Royal Holloway University of London)

Summary of project:



In terms of spatial resolution, vertebrate eye beats insect, but insects can excel at temporal resolution. In principle this could convert into higher spatial resolution than that implied by the static array of receptors. In terms of a frozen snapshot of the world, the spatial resolution of the insect eye is certainly inferior to the typical vertebrate eye. But this
picture neglects the dimension of time. The registration of temporal change can be much faster in the insect eye, and if this can be correlated with active (self-generated) scanning movement, then a type of spatial hyperacuity is possible for the insect visual system.

If temporal information is converted into spatial, this will in itself take some time, to allow for active scanning of the
image. If bees can be trained to recognize relatively simple visual
attributes on very brief exposure (no scanning) then the limits of this can be probed by investigating the exposure time required for more complex discriminations (which in humans can still be accomplished with remarkably brief exposure times). In other words, is active scanning more necessary for image formation in bees than in humans? This would be expected if spatial
hyperacuity depended on temporal resolution in bees. The candidate will be trained in behavioural methods to test bees. Electrophysiological experiments in this context
(using intracellular recordings) are also a possibility, and equipment and training will be provided.
