  • "Have you ever considered that the X-Men movies are not just about mutants with superhuman abilities but a perfect illustration of the ideas of the famous 17th century philosopher Spinoza? Just as the X-Men grapple with questions like "what makes us unique?? and "what are we capable of ?? so did Spinoza. That's according to Kirsty?s next guest, the philosophy professor Ollivier Pourriol who uses American blockbusters as teaching aids. " (BBC World Service)

  • "The brain does not simply gather and stockpile information as a computer?s hard drive does. Facts are stored first in the hippocampus, a structure deep in the brain about the size and shape of a fat man?s curled pinkie finger. But the information does not rest there. Every time we recall it, our brain writes it down again, and during this re-storage, it is also reprocessed. In time, the fact is gradually transferred to the cerebral cortex and is separated from the context in which it was originally learned. For example, you know that the capital of California is Sacramento, but you probably don?t remember how you learned it." ( NYTimes.com)

  • "The upshot is that atheism does not undermine morality, but atheists? conception of morality may depart from traditional theistic conceptions. Rather than condemning atheism, we might work to build institutions that promote charity more effectively among those who do not participate in organized religion, and we might try to develop secular foundations for morality to help guide people who do not consider God to be the source of moral rules. Both these efforts would serve atheists and theists alike." (Jesse Prinz)

  • "Serotonin (5-HT) has long been implicated in social behavior and impulsivity, but the mechanisms through which it modulates self-control remain unclear. We observed the effects of manipulating 5-HT function on behavior in the Ultimatum Game, where players must decide whether to accept or reject fair or unfair monetary offers from another player. Participants with depleted 5-HT levels rejected a greater proportion of unfair, but not fair offers, without showing changes in mood, fairness judgments, basic reward processing, or response inhibition. Our results suggest that 5-HT plays a critical role in regulating emotion during social decision-making." -- Crockett et al., 10.1126/science.1155577 -- Science

    • Wallace wrote up his ideas and sent them to Charles Darwin, already a naturalist of some reputation. His paper arrived on 18 June, 1858 - 150 years ago last week - at Darwin's estate in Downe, in Kent.
    • In order to preserve Darwin's claim on natural selection Hooker and Lyell arranged for a joint reading of both men's works at the Linnean Society in Burlington House, Piccadilly.
    • Self-educated and from a humble background, Wallace had none of the privileges accorded to university-educated Darwin, whose father was a prosperous doctor. He had had to make his way as an apprentice carpenter and then a trainee surveyor, before turning himself into a distinguished naturalist. He was also an early socialist, a supporter of women's rights, a backer of the land reform movement and a consummately skilful writer.

  • "Many people fear that science and technology are encroaching on domains of life in a way that undermines human dignity, and they see this as a threat that needs to be resisted vigorously. They are right. There is a real crisis, and it needs our attention now, before irreparable damage is done to the fragile environment of mutually shared beliefs and attitudes on which a precious conception of human dignity does indeed depend for its existence. I will try to show both that the problem is real and that the most widely favored responses to the problem are deeply misguided and bound to fail. There is a solution that has a good chance of success, however, and it employs principles that we already understand and accept in less momentous roles."

  • "The multiple drafts model of consciousness (Dennett, 1991, 1996, 1998, Dennett and Kinsbourne, 1992) was developed as an alternative to the perennially attractive, but incoherent, model of conscious experience Dennett calls Cartesian materialism, the idea that after early unconscious processing occurs in various relatively peripheral brain structures "everything comes together" in some privileged central place in the brain?which Dennett calls the Cartesian Theater --for "presentation" to the inner self or homunculus. There is no such place in the brain, but many theories seem to presuppose that there must be something like it." (Dennet & Akins, Scholarpedia)

  • "The June 14 Episode of All in the Mind has a thoughtful discussion of the implications of using drugs to improve cognitive performance. Natasha Mitchell interviewed Barbara Sahakian, professor of Neuropsychology at the University of Cambridge (UK) and William Glannon, a bioethicist from the University of Calgary (Canada). Several important issues emerged including the fact that that it is unknown whether the drugs currently available are safe for long-term use. There is also the nagging question of whether the use by normal people of drugs originally intended to treat medical conditions (like ADHD) constitutes cheating? What do you think?"

  • "A conference is being held in Sydney soon about whether God is necessary for morality. I find that an almost incomprehensible question. Of course humans are moral without gods to back up their moral systems. They can't help it. It's what humans do. We are social apes that follow rules. Sometimes the sanctions for following rules (which turn out to be sanctions for potential defectors rather than the majority, who will tend to follow rules with or without promises of reward or punishment) rely on a god. Mostly, they don't." (Evolving Thoughts)

  • "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"."

  • "Over the past few years I?ve had an uncomfortable sense that someone, or something, has been tinkering with my brain, remapping the neural circuitry, reprogramming the memory. My mind isn?t going?so far as I can tell?but it?s changing. I?m not thinking the way I used to think. I can feel it most strongly when I?m reading. Immersing myself in a book or a lengthy article used to be easy. My mind would get caught up in the narrative or the turns of the argument, and I?d spend hours strolling through long stretches of prose. That?s rarely the case anymore. Now my concentration often starts to drift after two or three pages. I get fidgety, lose the thread, begin looking for something else to do. I feel as if I?m always dragging my wayward brain back to the text. The deep reading that used to come naturally has become a struggle."

Gall's phrenology was largely discredited by the mid-19th century. That didn't stop Moritz Benedikt, however, from postulating that morality was located in the occipital lobes! (Verplaetse, 2004).

  • "What's new is that the researchers were able to determine that an emotion-related region called the insula was responsible for encoding the equity of each option, whilst a reward-based region called the putamen was involved in encoding efficiency. In fact, differences in how sensitive each participant was to these two concerns was reflected in their levels of brain activity in these two regions.

    The findings provide a biological perspective on age-old philosophical questions about distributive justice, and appear to support the view of thinkers such as David Hume and Adam Smith who argued that emotions play a fundamental role in moral decisions of this kind." (BPS RESEARCH DIGEST)

But for kids much younger than 6, the phenomenon becomes quite difficult to study.

You can't ask them to draw the picture for you -- they can barely sit up, let alone hold a pencil." (Cognitive Daily)

  • "A new study presents evidence of symbolic reasoning in tufted capuchin monkeys, a South-American species that diverged from humans about 35 million years ago. In the experiment, five capuchins engaged in "economic choice" behavior. Each monkey chose between three different foods (conventionally referred to A, B and C), offered in variable amounts. Choices were made in two different contexts. In the "real" context, monkeys chose between the actual foods. In the "symbolic" context, monkeys chose between "tokens" (intrinsically valueless objects such as poker chips) that represented the actual foods. After choosing one of the two token options, monkeys could exchange their token with the corresponding food." (Science Daily)

Other research has found that the motion of the ankle appears to be a key in identifying biological motion. This may be because nearly all walking vertebrates swing their legs forward in a similar manner: they don't actually use their muscles, but instead simply rely on gravity, thus conserving energy. Chang and Troje speculate that perhaps it is this distinctive arc that viewers focus in on when they identify biological motion." (Cognitive Daily)

From Inside Higher Ed, a discussion with an author about a new book on the shift in higher education to corporate values and its impact on the professorship.
Two much-discussed trends in academe — the adoption of corporate values and the decline in the percentage of faculty jobs that are on the tenure track — are closely linked and require joint examination. That is the thesis of a new book, The Last Professors: The Corporate University and the Fate of the Humanities, just published by Fordham University Press.
The trends expressed in the article are certainly reflected at my own university. We've even stopped talking about our vision for liberal education and now refer to the "business plan." We dropped the expression "learner-centered" and now strive to "develop talent." And non-tenured faculty dramatically outnumber tenured/tenure-track faculty.

  • "Humans, as I have described, evolved to live in small isolated groups and are finely tuned to seek people of common values. Like it or not, common culture (common practices, expectations, and beliefs) correlates, even if imperfectly, with common biological ancestry.

  • "Imagine that mad scientists defied nature and violated the barriers between species. They injected human DNA into non-human creatures, altering their genomes into chimeras--unnatural fusions of man and beast. The goal of the scientists was to enslave these creatures, to exploit their cellular machinery for human gain. The creatures began to produce human proteins, so many of them that they become sick, in some cases even dying. The scientists harvest the proteins, and then, breaching the sacred barrier between species yet again, people injected the unnatural molecules into their own bodies." (Carl Zimmer)

Perhaps in the future, questions about higher brain functions will be better understood because of new genetic and neurophysiological discoveries and brain imaging. An unexpected scientific discovery can give us a new insight into something we thought we had always known: mirror neurons, Rizzolatti tells us, "show how strong and deeply rooted is the bond that ties us to others, or in other words, how bizarre it would be to conceive of an I without an us."'

Their analysis further reveals sex differences in the recruitment of OFC, which distinguished attractive and unattractive faces only for male participants.
