Category representation in the brain
Jack Gallant has been focusing a lot of recent lab efforts in the analysis of large-scale fMRI recordings. They published an interesting paper in Neuron last month about the representation of categories in cortex.

Fitting a convolutional model of V1
Fresh off the press from NIPS 2012 is a paper by Vintch et al on a convolutional model of V1. Unsurprisingly, the convolutional model (or as they call it, the subunit model) beats the crap out of an STC-based model since it captures the same basic features of the RFs in a much lower dimensional…

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…

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,…

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…

Is beer the answer?
Disclaimer: This post is about how alcohol interferes with memory formation and how that can be paradoxically beneficial under very special circumstances. Think of the plot of Eternal Sunshine of the Spotless Mind, you’ll get the idea. It’s not a license to get drunk. Jeeze. Well-meaning friends and family members may suggest that you have…
