1. HOW WE NAVIGATE IN SPACE
Cognitive map (Tollman, 1948)
The Nobel Prize in Physiology or Medicine 2014
John O’Keefe, May-Britt and Edvard I. Moser - "for their discoveries of cells that
constitute a positioning system in the brain„
So far what we know is mostly based on animal experiments
Place cells (O’Keefe & Dostrovsky, 1971)
Grid cells (Hafting, Fyhn, Molden, M. B. Moser & E. Moser, 2005)
Head direction cells (Taube, Muller, Ranck, 1990)
2. WINDOWS INTO THE BRAIN
Several methods to measure neurak activity directly …
ECoG
Deep brain electrodes
EEG
MEG
And indirectly
fMRI
PET, SPECT
NIRS
3. NECESSITY OF TOOLS
Measure brain activity during
Active motion
In a 3 dimensional space
Recent advancement
Portable EEG devices
CAVE and HMD systems (Oculus Rift)
Motion tracking
Online realistic graphical rendering
Communication between neuroscientists and computer
scientists
4. HOW CAN WE SET UP AN EXPERIMENT
T-maze experiment
Do they prefer one alley? Are the fruits associated with one alley?
Talk
Define the experiment
Define the terms
Define the key features
5. IMPLEMENTATION

T-Maze Experiment Descriptor
Movements depends on user choice
Deep brain electrodes are extremely sensitive to even the slightest motion (e.g. even breathing, heart beat can dislocate them thus hurting cells nearby)
Mri, MEG and PET are extremely big, cannot be transformed to a carry-on tool
Communication has already taken place before
How do we encode an object’s position in space
Relative to us? „the laptop is on my left”
Relative to the environment? „the laptop is on the table”
Why is egocentric coding preferred in one situation and allocentric in another?
