Brain Science Podcast - Brain science lite, in my opinion. Some great interviews and reviews with some of my favorite academic heroes and heroines.
Books & Ideas - Same host as BSP, with a lite lite feel. I tried to have her get Bakker and Neuropath on it but to no apparent avail.
Alex Jones - Because "real" news sucks and this is much more entertaining, if barely critical...
Cutting Through the Matrix - Because he's Scottish, because he lives in the wilderness of Canada, and because "real" news sucks - professionalism is lax, if only a little more heavily critical...
I have a number of others in mind but you've sent me digging, Sci. I shall be back to add a few more of my favorite (though to be fair, I basically only listen to BSP or Alex Jones with breakfast, being my little free time at the moment).
