Chemical Synapse

Study identifies a novel role for a protein related to synaptic vesicles.

I often write on this blog that neurons in our brain are linked to each other by multiple connections. We call those connections synapses, but I never took the time to explain in detail how they work. It is a fascinating subject which constitutes an enormous field of research by itself. Here is an illustration of such a synapse and how one neuron sends signals to the next neuron. Continue reading

The New Neuron Connectome

You know what’s nuts? That we still don’t know the basics. Forget patch clamping thousands of neurons in vivo during awake behaviour. Simultaneously. In humans. In outer space. I just want to know exactly which other neurons my neuron is talking to. Not even. Which neurons is my neuron touching, intimately, in a putative synaptic contact sort of way? WHICH NEURONS MY NEURON DONE BEEN TOUCHING, YA DIG?? Continue reading

Semantics, categories and the brain.

How the brain stores and manipulates categories of objects is a quite interesting scientific question – but a difficult one. Every noun in a language represents some sort of category. Oak trees, for instance, is a category that regroups every individual oak tree. Continue reading

Cell Patch Clamp

The science behind Obama’s BRAIN project.

On April 2nd, 2013 President Obama announced the BRAIN initiative, a project aimed at understanding brain activities at a level of detail that is unprecedented. A lot has been said and written about the initiative but some people feel in the dark as to what are its precise aims. Continue reading

Representation of the different types of memory

A live google hangout to answer your questions about memory and the brain.

I got a message from science writer Bruce Lieberman announcing that he will be hosting a live webcast on Thursday April 11, 11:30AM with Bradford Dickerson, Associate Professor of Neurology at the Harvard Medical School and Mayank Mehta, Professor of Neurophysics at the Brain Research Institute at the University of California. This looks like a good occasion for those of you who want to learn about how memory works and ask questions to renowned experts in the field! Continue reading
