Razib and I have a discussion up at Bloggingheads.tv about genetics and behavior as well as a brief discussion of neuroeconomics. Check it out below the fold:

There is a fascinating case study in Current Biology. de Gelder et al. discuss a patient — referred to as TN to protect his privacy — who had two sequential strokes that damaged his brain. The parts of the brain that were damaged included the primary visual cortex in both hemispheres — rendering the patient…

I don’t think I am alone in saying that I often feel a little envy and schadenfreude towards my peers. Science is a particularly competitive business with few remunerative rewards, so a lot of my self-worth is tied to comparisons with my peer’s successes and failures. I won’t deny being envious when someone gets a…

The title of this pre-publication paper is, “Evidence on the emergence of the brain’s default network from 2-week-old to 2-year-old healthy pediatric subjects.” The authors put kids in functional MRIs to measure resting state activity and detect the emergence of the default network. While I am certain that it is very interesting research, I have…

I know this will be of interesting for about 1 in a hundred of you, but there is a REALLY good review of hippocampal and parahippocampal region connectivity in April’s Nature Review Neuroscience. Of special interest, there is an interactive .pdf in the supplementary information where you can identify the connections between one region to…

This post over at Neuroskeptic reignites a debate — if it ever really stopped — as to the role of impaired adult neurogenesis in causing depression and the function of anti-depressants in stimulating neurogenesis to treat the disease. This is one of those hot topics in neuroscience. If you look away for just a second…

I caught this article in O magazine by fellow ScienceBlogger, Rebecca Skloot of Culture Dish. The article isn’t bad. It is about why people have trouble overcoming unproductive habits like trouble exercising.  But I want to correct something she says that is inaccurate. Dopamine has a primary role in the signaling reward, and this is…

Seriously, when I read the headlines to this article, I wanted to wretch retch. (Ed. I need to learn how to spell.) Scientists discover true love Scientists: True love can last a lifetime I can feel it welling up now…eh…OK, I feel better. Just to be clear, I didn’t want to wretch retch because I…

I caught this article on ScienceDaily about the work of Professor Bart Hoebel at Princeton who has been attempting to show that sugar is an addictive substance like a drug. He presents data at the American College of Neuropsychopharmacology meeting to suggest that sugar fulfills the criterion for substances that we traditionally define as addictive:…

RIP Patient H.M.

Patient H.M. just died: In 1953, he underwent an experimental brain operation in Hartford to correct a seizure disorder, only to emerge from it fundamentally and irreparably changed. He developed a syndrome neurologists call profound amnesia. He had lost the ability to form new memories.
