Modifying body representation through vision and vice versa
There’s a few interesting multi-modal illusions involving vision and another sense. Proprioception, the ability to sense the position of one’s body parts, is one sense that gets a bad rep; it’s not even included in the classic 5 senses. Yet it’s certainly quite important, and people that lose proprioception have difficulty functioning at first, a

Poor man’s parallel computing on multiple computers in Matlab
Let’s say that you need to run the same analysis with multiple datasets; for instance, you need to do reverse correlation with multiple cells. This might take a while, so you would like to run the analysis on multiple computers. The computers might be a bit different from each other, as well as the recording

Hearing radio frequencies
I was reading the Wikipedia article on tinnitus, and came across this pearl of a sentence: A common and often misdiagnosed condition that mimics tinnitus is Radio Frequency (RF) Hearing in which subjects have been tested and found to hear high-pitched transmission frequencies that sound similar to tinnitus. Hmm, what? Yes, humans, under special circumstances,

Experiential blindness through inversion glasses
Inversion glasses, which invert the visual field along the left-right or up-down axes, have been used to investigate the link between action and perception for at least a 100 years (Stratton 1897). As I mentioned in my last post, they really mess up perception by disrupting the usual links between motor commands, optic flow, eye

Action in perception
Mu-Ming Poo delivered a talk at the MNI a few years back on his work on spike-timing dependent plasticity (STDP). He mentioned that to get good ideas for new experiments, you should start by reading old rather than current literature (in his case, the works of Donald Hebb). His reasoning was that the questions raised

Modeling the Spatial Reach of LFP
As regular readers will know, I’ve been intrigued by the nature of local field potential for some time. There’s a recent paper in Neuron by Lindén et al. that uses a modeling approach to explain the spatial reach of the LFP. This is a subject of some controversy; the spatial reach of the LFP has
