by News Sources 05.20.2013

Riken: In our interaction with our environment we constantly refer to past experiences stored as memories to guide behavioral decisions. But how memories are formed, stored and then retrieved to assist decision-making remains a mystery. By observing whole-brain activity in live zebrafish, researchers from the RIKEN Brain Science Institute have visualized for the first time [...]

Bach to the blues, our emotions match music to colors

by Attention to the Unseen 05.20.2013

UC Berkeley: Whether we’re listening to Bach or the blues, our brains are wired to make music-color connections depending on how the melodies make us feel, according to new research from the University of California, Berkeley. For instance, Mozart’s jaunty Flute Concerto No. 1 in G major is most often associated with bright yellow and [...]

Cesare Lombroso, a psychiatrist and prison doctor at an asylum for the criminally insane, was performing a routine autopsy on an infamous Calabrian brigand named Giuseppe Villella. Lombroso found an [...]

Reliability of neuroscience research questioned

by Attention to the Unseen 04.14.2013

Bristol University: New research has questioned the reliability of neuroscience studies, saying that conclusions could be misleading due to small sample sizes. A team led by academics from the University of Bristol reviewed 48 articles on neuroscience meta-analysis which were published in 2011 and concluded that most had an average power of around 20 per [...]

Obama’s big BRAIN project

by News Sources 04.05.2013

Kas Thomas writes: President Obama’s kickoff of the BRAIN initiative was a major news item the other day. Widely lauded as the kind of program that can keep America at the forefront of science, Brain Research through Advancing Innovative Neurotechnologies (or, if you prefer, Big Ridiculous Acronyms Inspired by Nonsense) was compared to the Apollo [...]

Dystopian fiction not far from becoming security state reality

by Attention to the Unseen 03.27.2013

Nature: In a twist that evokes the dystopian science fiction of writer Philip K. Dick, neuroscientists have found a way to predict whether convicted felons are likely to commit crimes again from looking at their brain scans. Convicts showing low activity in a brain region associated with decision-making and action are more likely to be [...]

The neuroscience of finding your lost keys

by Attention to the Unseen 03.22.2013

Salk Institute: Ever find yourself racking your brain on a Monday morning to remember where you put your car keys? When you do find those keys, you can thank the hippocampus, a brain region responsible for storing and retrieving memories of different environments-such as that room where your keys were hiding in an unusual spot.

Mind control in the name of medicine

by Paul Woodward 03.01.2013

Is it possible to connect two brains in such a way that the thoughts in one could control those in the other? That sounds like a question whose answer would have interested Hitler and Stalin. Wouldn’t this be every dictator’s dream: not only the capacity to control how others behave but also how they think? [...]

Songbirds’ brains coordinate singing with intricate timing

by Attention to the Unseen 02.28.2013

University of Chicago: As a bird sings, some neurons in its brain prepare to make the next sounds while others are synchronized with the current notes—a coordination of physical actions and brain activity that is needed to produce complex movements, new research at the University of Chicago shows. In an article in the current issue [...]

How flies fly and what makes flies smarter than people

by Paul Woodward 02.24.2013

Evolution, viewed as a process of progression (which it isn’t) leads to the notion that as the possessors of the most complex brains, we sit proudly at the top of the evolutionary pyramid. Even if one doesn’t question that it makes sense to assign ourselves this position, there’s no disputing that our tenure has thus [...]

Human cognition depends upon slow-firing neurons

by Paul Woodward 02.22.2013

YaleNews: Good mental health and clear thinking depend upon our ability to store and manipulate thoughts on a sort of “mental sketch pad.” In a new study, Yale School of Medicine researchers describe the molecular basis of this ability — the hallmark of human cognition — and describe how a breakdown of the system contributes [...]

Neurons gone wild

by Attention to the Unseen 01.11.2013

Daniel Dennett says: Each neuron is imprisoned in your brain. I now think of these as cells within cells, as cells within prison cells. Realize that every neuron in your brain, every human cell in your body (leaving aside all the symbionts [such as mitochondria]), is a direct descendent of eukaryotic cells that lived and [...]

Measuring consciousness

by Attention to the Unseen 01.07.2013

In a feature article for the Atlantic, Joshua Lang explores the phenomenon of anesthesia awareness: where patients undergoing surgery are conscious yet paralyzed and thus unable to signal the pain and terror they are experiencing. On a warm afternoon in Madison, Wisconsin, last spring, a psychiatrist was pointing an electromagnetic gun at my brain. “Put [...]

How our brains categorize and map everything we see

by Attention to the Unseen 12.24.2012

ExtremeTech: If not for our brains, our eyes wouldn’t be able to process anything. Considering how much time we spend with our eyes open, our brains are constantly dealing with an influx of visual data. The brain needs to store that data somewhere, and thanks to scientists over at the University of California, Berkeley, we [...]

Does self-awareness require a complex brain?

by Attention to the Unseen 09.02.2012

Ferris Jabr writes: The computer, smartphone or other electronic device on which you are reading this article has a rudimentary brain—kind of. It has highly organized electrical circuits that store information and behave in specific, predictable ways, just like the interconnected cells in your brain. On the most fundamental level, electrical circuits and neurons are [...]

The trust molecule

Paul J. Zak writes: Could a single molecule — one chemical substance — lie at the very center of our moral lives? Research that I have done over the past decade suggests that a chemical messenger called oxytocin accounts for why some people give freely of themselves and others are coldhearted louts, why some people [...]
