Cognitive Science podcasts to follow
Here are the ones I know about; there's much more about neuroscience than, say, theoretical or computational cognitive science, but a lot of the neuroscience podcasts cover cognitive science indirectly or partially.

All in the Mind--it's also neuroscience and mental health stuff (a lot of mental health stuff)

Brain Science Podcast--books about and interviews with researchers in neuroscience

Neuropod--Nature's neuroscience podcast

Neuroscene--"the future of neuroscience", mostly interviews or topical explorations

Naked Neuroscience--the neuroscience offshoot of Cambridge University's Naked Scientists
