Visualizing The Connected Brain
by Neuroskeptic in Neuroskeptic
So it seems as though the "connectome" is the latest big thing in neuroscience. This is the brain's wiring diagram, in terms of the connections between neurons and on a larger scale, between brain regions.We certainly won't understand the brain without getting to grips with the connections but equally, it's not the whole story. I previously emphasised that the brain is not made of soup; it's not made of spaghetti, either.Connectomics does however unquestionably provide some of the prettiest imag........ Read more »

a human and a monkey walk into an fMRI scanner…
by Tal Yarkoni in citation needed
Tor Wager and I have a “news and views” piece in Nature Methods this week; we discuss a paper by Mantini and colleagues (in the same issue) introducing a new method for identifying functional brain homologies across different species–essentially, identifying brain regions in humans and monkeys that seem to do roughly the same thing even if they’re [...]...

Deaf hearing
by Janet Kwasniak in Thoughts on thoughts
A recent paper examined a patient with deaf-hearing, analogous to blind-sight, where there can be detection of a signal without conscious awareness of it. (citation below) For example, a person with blind-sight may avoid an obstacle without awareness of it; and, a deaf-hearing person may be startled and orient towards a noise without consciously hearing [...]...
