Evolutionary origins of the nervous system
THE HUMAN BRAIN is a true marvel of nature. This jelly-like 1.5kg mass inside our skulls, containing hundreds of billions of cells which between them form something like a quadrillion connections, is responsible for our every action, emotion and thought. How did this remarkable and extraordinarily complex structure evolve?
Brain immediately recognizes transplanted hand
Amputation of a limb leads to significant reorganization of the primary somatosensory cortex, that part of the brain which processes touch- and pain-related information. The cortical region normally devoted to the amputated body part is suddenly deprived of sensory inputs, but because the adult brain is plastic, it does not lay dormant - the area assumes other functions, and begins to process sensory information from other parts of the body.

Brain Science Podcast #55: Patricia Churchland on Neurophilosophy
In this interview we talked about neurophilosophy, which is an approach to philosophy of mind that gives high priority to incorporating the empiric findings of neuroscience. We also talk about the evolving relationship between philosophy and neuroscience. Churchland shares her enthusiasm for how the discoveries of neuroscience are changing the way we see ourselves as human beings. We also talked a little about the issues of reductionism that I first brought up in Episode 53.
The neurological basis of intuition
According to a new study, our gut feelings can enhance the retrieval of explicitly encoded memories - those memories which we encode actively - and therefore lead to improved accuracy in simple decisions. The study, which is published online in Nature Neuroscience, also provides evidence that the retrieval of explicit and implicit memories involves distinct neural substrates and mechanisms.

Young neurons led astray
"Cdk5 therefore appears to be crucial only for later stages of the maturation of newborn neurons. The authors suggest that the improper connections formed by these cells could interfere with information processing in the hippocampus. However, they did not carry out any behavioural tests to explore the consequences of blocking cdk5 activity. This would be an interesting thing to do next, given the recent discovery that new neurons are needed for new memories. Nevertheless, the new findings could have important implications for the use of stem cells in cell replacement therapies for neurological diseases, as they suggest that cells would have to be transplanted accurately into specific locations in order to be effective.

Anatomy of a false memory
"If confabulation occurs following damage to the ventromedial cortex, what functions might this part of the brain be involved in? Some researchers have suggested that it normally suppresses memories that are not relevant to the current situation, while others argue that it acts as a monitoring system which normally rejects false memories that don't "feel right"." (Neurophilosophy)
Augmented cognition: Science fact or science fiction?
"The limitations of cognitive processes, particularly attention and working memory, place a ceiling on the capacity of the brain to process and store information. It is these processes that some researchers are aiming to enhance with augmented cognition, an emerging field which aims to use computational technology to enhance human performance in various tasks by overcoming the bottlenecks in processes such as attention and memory. " (Neurophilosophy)
An interview with Eric Kandel (video)
Among the topics Kandel discusses in the interview are the differences between biological and digital memory, neurogenesis in the hippocampus, free will and consciousness, drug development and the use and abuse of drugs by children, and the state of science in the U.S. and Europe. (Neurophilosophy)
