This is your brain on love. Brains are big on campus, too. Take a map of any major university and you can trace the march of neuroscience from research labs and medical centres into schools of law and business and departments of economics and philosophy.

In recent years, neuroscience has merged with a host of other disciplines, spawning such new areas of study as neurolaw, neuroeconomics, neurophilosophy, neuromarketing and neurofinance. As a newly minted cultural artefact, the brain is portrayed in paintings, sculptures and tapestries and put on display in museums and galleries.

Clearly, brains are hot. The prospect of solving the deepest riddle humanity has ever contemplated — itself — by studying the brain has captivated scholars and scientists for centuries.

But never before has the brain so vigorously engaged the public imagination. The prime impetus behind this enthusiasm is a form of brain imaging called fMRI, or functional magnetic resonance imaging, an instrument that measures brain activity and converts it into the now iconic vibrant images one sees in the science pages of the daily newspaper.

As a tool for exploring the biology of the mind, neuroimaging has given brain science a strong cultural presence. With its implied promise of decoding the brain, it is easy to see why brain imaging would beguile almost anyone interested in pulling back the curtain on the mental lives of others: The problem is that brain imaging cannot do any of these things — at least not yet.

Author Tom Wolfe was characteristically prescient in when he wrote of fMRI injust a few years after its introduction: First, of course, there is the very subject of the scans: More complex than any structure in the known cosmos, the brain is a masterwork of nature endowed with cognitive powers that far outstrip the capacity of any silicon machine built to emulate it.

Containing roughly 80bn brain cells, or neurons, each of which communicates with thousands of other neurons, the 3lb universe cradled between our ears has more connections than there are stars in the Milky Way.

How this enormous neural edifice gives rise to subjective feelings is one of the greatest mysteries of science and philosophy. Brain scan images are not what they seem. They are not photographs of the brain in action in real time. Those beautiful colour-dappled images are actually representations of particular areas in the brain that are working the hardest — as measured by increased oxygen consumption — when a subject performs a task such as reading a passage or reacting to stimuli, such as pictures of faces.

Despite well-informed inferences, the greatest challenge of imaging is that it is very difficult for scientists to look at a fiery spot on a brain scan and conclude with accuracy what is going on in the mind of the person.

Barack Obama shortly after winning the US presidential election. Research undertaken by neuroscientists suggested that he would fail to engage with voters. They scanned the brains of swing voters as they reacted to photos and video footage of the candidates.

An encyclopedia of philosophy articles written by professional philosophers.

Readers could view scans dotted with tangerine and neon-yellow hotspots indicating regions that "lit up" when the subjects were exposed to images of Hillary Clinton, John Edwards, Rudy Giuliani, and other candidates. Revealed in these activity patterns, the authors claimed, were "some voter impressions on which this election may well turn".

Among those impressions was that two candidates had utterly failed to "engage" with swing voters. Who were these unpopular politicians? John McCain and Barack Obama, the two eventual nominees for president. University press offices are notorious for touting sensational details in their media-friendly releases: Neuroscientists themselves sometimes refer disparagingly to these studies as "blobology", their tongue-in-cheek label for studies that show which brain areas become activated as subjects experience x or perform y task.

Skilled science journalists cringe when they read accounts claiming that scans can capture the mind itself in action.

Serious science writers take pains to describe quality neuroscience research accurately.Novel framing of Smartphone use as instantiation of extended mind. • Lower analytic thinking associates with increased Smartphone use. • Results suggest that people offload thinking to the device.

Neanderthal: Neanderthal, one of a group of archaic humans who emerged at least , years ago in the Pleistocene Epoch and were replaced or assimilated by early modern human populations (Homo sapiens) 35, to perhaps 24, years ago. They inhabited Eurasia from the Atlantic through the Mediterranean to Central Asia.

The mind is a set of cognitive faculties including consciousness, perception, thinking, judgement, language and is usually defined as the faculty of an entity's thoughts and consciousness.

It holds the power of imagination, recognition, and appreciation, and is responsible for processing feelings and emotions, resulting in attitudes and actions. The past few decades have produced important advances in our understanding of how the brain regulates emotion and cognition. In comparison, research on the neuroscience of human social behaviour is a relatively neglected topic in spite of the importance of social interactions for mental health.
