Roland Philipp

Cortical Control of Skilled Hand Function & Mirror Neurons

r.philipp{at}ucl.ac.uk


I started my scientific career at the Ruhr-University Bochum, Germany, where I received my MSc and PhD degree in Klaus-Peter Hoffmann's Lab. In short I can summarise the results of my PhD thesis as follows: We investigated if and how the Superior Colliculus (SC) is involved in the generation and control of visually guided arm movements. Using three different approaches we could show that I) electrical microstimulation elicits arm movements in a naïve monkey (Macaca mulatta), II) electrical microstimulation influences an ongoing movement plan, and III) that sudden target perturbations are reflected in the discharge of collicular reach neurons
(PhD full text).

During my Master's thesis we recorded from the extra striate visual cortex from anaesthetised pigmented and albino ferrets (Mustela putorius furo) and were able to localise a circumscribed cortical area (PSS) which contains direction selective neurons and shares specific characteristics with the primate medial superior temporal area (MST) Oxford open free text.

Currently I am working as a Research Fellow on the Mirror Neuron Project which is funded by the "Wellcome Trust Project Grant (Kraskov and Lemon)". The main focus of my work is presently to analyse and interpret the oculomotor pattern of a monkey while participating in an interactive mirror task requiring action execution and action observation.
