Season 2 Episode 7 – Neurofeedback with Dr. Freddy Starr

Hello listeners! We’re pleased to bring you a brand new podcast today in which we interview Dr. Freddy Starr who works in the field of Brain-Machine Interfaces and neurofeedback. We really enjoyed doing this interview and have several more casts involving interviewees coming up.

A few notes: 1) This cast covered many borders, both state and national, so the recording quality may not be quite what you are used to. The discussion is fascinating though so we hope you’ll bear with us. 2) We mention “Cz” several times throughout the cast. This refers to a point on the scalp at which an electrode is placed. If you google EEG electrode placement you can find maps of common scalp coordinates. 3) We mention different brain wave rhythms at several points in this cast. There are a lot of pseudoscience-touting, BS websites out there that will mislead you. Therefore, we recommend you get info from a reliable source such as this one (though the website is under maintenance at the time of posting) – http://www.scientificamerican.com/article/what-is-the-function-of-t-1997-12-22/

Note the several regions within the meninges where fluids like blood and cerebrospinal fluid have the capacity to displace the meninges and thereby activate pain receptors therein.

Toward the end of the cast, Ryan mentions a book called “Better Never to Have Been.” Here’s a link to the book on Amazon in case you are curious about it and/or want to pick it up!

Episode 8 – Neurolaw Show Notes

Phineas Gage (since we mentioned him) is an early confirmed example of a brain disturbance producing profound personality changes.

This man had pedophelic urges until a huge tumor was removed from his frontal lobe. When the tumor returned, so did the urges. A fascinating case study in brain disturbances producing dramatic changes in behavior.

The famous Houston sniper also had a brain tumor which might have influenced his behavior. His writings certainly suggest that he found himself thinking disturbing thoughts in the period leading up to the shootings.

Capgras syndrome and other delusional syndromes  may result in crimes motivated by bizarre reasons.

fMRI scans can predict recidivism rates, but whether the findings can be applied to individual persons remains unclear.

This guy has a ‘psychopathic brain’ but is not a psychopath. While brain scans can inform us of trends among large groups of people, predictive power can be lacking for individuals. We might ask if more traditional methods are any better–as Joel mentions in the podcast, the actuarial tables used to predict recidivism rates make broad recommendations based on average trends as well.

Episode 6 – Phantom Limbs and Foot Fetishes! – Show Notes

Left: Loss of the arm allows nearby sensory regions to ‘take over’ the lack of space

Right: If our body parts were as relatively big as the space devoted to them in terms of cortical area.

Penfield’s homunculus looks super gross, but it shows how sensation coming in from the hands and mouth is the most discriminating touch on our bodies. This makes sense, given that they are the primary tools we use to explore the environment (remember that we use our mouths to inspect new foods, for example, which is crucial to allow us to live!)

Ramachandran describes phantom limb, along with some other conditions

Enjoy the podcast!
