The evolutionary psychology of war

Nothing too shocking here for students of evolutionary psychology but it’s always interesting to see real world examples of how our shared behavior. There is a new book by Sebastian Junger called War, in which he recounts how men do not fight for larger ideological goals (eg. “a safer Iraq”, “finding Bin Laden”) but instead they can overcome fears because “they’re more concerned about their brothers than what happens to themselves individually”. Here’s Junger on Good Morning America:

After the jump some more from Junger and a nice talk from Robert Sapolsky about similar behaviors in chimps.

Dendritic organization of sensory input to cortical neurons in vivo

Jia, H., Rochefort, N., Chen, X., & Konnerth, A. (2010). Dendritic organization of sensory input to cortical neurons in vivo Nature, 464 (7293), 1307-1312 DOI: 10.1038/nature08947

Consider a a cortical neuron in V1, layer 2/3, whose output shows sharp orientation tuning. What are the orientation tunings of the most important inputs to that neuron? What is the spatial distribution of these inputs in the neuron’s dendritic tree?
