Information theory of behavior

by neuroecology in Neuroecology

Biology can tell us what but theory tells us why. There is a new issue of Current Opinion in Neurobiology that focuses on the theory and computation in neuroscience. There’s tons of great stuff there, from learning and memory to the meaning of a spike to the structure of circuitry. I have an article in this issue and […]... Read more »

The story of the phospholipase A superfamily

by Clay Clark in Biochem Blogs

  The phospholipase A2 superfamily is a group of enzymes that cleave fatty acid groups from glycerol, in particular acyl groups at the sn-2 position. They contribute to numerous metabolic processes and diseases, including Alzheimer, epilepsy and multiple sclerosis; making this group of proteins very attractive to study. This superfamily includes groups such as secreted, […]... Read more »

COFFEE VS. PARKINSON’S DISEASE – CAN CAFFEINE REDUCE THE RISK OF DEVELOPING THE DISEASE?

by Robb Hollis in Antisense Science

There are a number of genetic and environmental factors known to affect the development and progression of the disease, but the exact underlying cause of the neuronal degeneration is still largely unknown. Studies of Parkinson’s in families have revealed that genetic factors are likely to contribute to the development of early-onset Alzheimer’s disease in particular. The list of environmental factors associated with Parkinson’s is extensive, including increased risk with exposu........ Read more »

Knowing your grandmother

by Janet Kwasniak in Neuro-patch

There is a spectrum of ways in which the brain may hold concepts that range from very localized to very distributed, and there is little agreement of where along that spectrum various concepts are held. At the one end is the ultimate local storage: a single ‘grandmother’ neuron that recognizes your grandmother in matter how […]... Read more »

Chronic Fatigue Syndrome and various factors

by Paul Whiteley in Questioning Answers

The paper by Kate Lievesley and colleagues [1] documenting various "predisposing, precipitating and perpetuating factors in Chronic Fatigue Syndrome in children and adolescents" caught my eye recently. Based on a review of the research literature around the topic of Chronic Fatigue Syndrome (CFS) [in childhood], the authors set about detailing some of the important factors linked to the condition and in doing so, highlighted how physiology and psychology might combine when it........

Is ketamine really a plausible treatment for depression?

by in Neuroscientifically Challenged

Last week, a publication in the Journal of Psychopharmacology made international news by reporting that patients with treatment-resistant depression (TRD) showed improvement after being given the dissociative hallucinogenic drug ketamine. Ketamine, which is traditionally used as an anesthetic in humans and other animals, is probably better known for its use as a party drug (in this context it is often called "special K"). However, a growing body of evidence has begun to suggest that ketamine may........ Read more »

Did I Do That? Distinguishing Real from Imagined Actions

by Rebecca Schwarzlose in Garden of the Mind

If you’re like most people, you spend a great deal of your time remembering past events and planning or imagining events that may happen in the future. While these activities have their uses, they also make it terribly hard to keep track of what you have and haven’t actually seen, heard, or done. Distinguishing between memories of real experiences and memories of imagined or dreamt experiences is called reality monitoring and it’s something we do (or struggle to do) all of the ........

The Genetics of Religious Belief

by William Yates, M.D. in Brain Posts

In the next few posts, I will review some of the recent brain-related research related to religious belief.Religious belief and religious affiliation run in families. This effect is not surprising as parents influence their children's type of religious experience during development.However, there is increasing evidence that adult religious belief and behavior is also influenced by genetic factors independent of family environment experience.Twin studies represent a powerful research model to tea........

Keeping past and future at a distance
