What makes a memory? Prof Tomás Ryan, TCD will explain in public talk

How are our memories, thoughts, and experiences stored in the brain?

The scientific search for what precisely makes a memory and the physical basis of self is older than science, psychology, or modern medicine.

The search even predates the theory of evolution and over the centuries has been led by priests and physicians, philosophers and physicists.

Only in recent time has a basic understanding of memory emerged from modern scientific investigations. Though such investigations are still in their infancy, some surprising findings have emerged.

In this public lecture, Assistant Professor in Trinity College Dublin’s School of Biochemistry and Immunology, Tomás Ryan, will discuss recent technology that he and his colleagues have developed that allows us to label and switch on (or off) specific memories.

Professor Ryan will also describe how such technology has allowed us to gain unprecedented insights into the true nature of memory loss, amnesia, and depression, before elaborating on the implications of such studies for our understanding of aging, dementia, mental health, and the nature of our own individuality.

The talk takes place in the Stanley Quek Theatre, Trinity Biomedical Sciences Institute, Pearse Street.

Date: Wednesday, October 25th, 6:30 pm. Admission is FREE and all are welcome.

Better treatments for nerve damage can follow new CÚRAM research

Better treatment methods for regeneration or repair of nerve tissue can follow new CURAM research (Pic: CURAM)

Better treatment options for those that have suffered nerve damage can result from new research at, based at NUI Galway, according to researchers.

The treatment of peripheral nerve injuries that result in the loss of motor or sensors remains a major problem around the world.

However, new research at the Centre for Research in Medical Devices, supported by SFI, can provide improved treatment options. The results of the new study were published in the journal Advanced Functional Materials.

Researchers have used artificial nerve grafts in recent years in an attempt to restore the function of the injured peripheral nervous system; which is that part of the nervous system that lies outside the brain and spinal cord.

This study explored the differences in nerve repair that result from the use of such grafts made of two different materials: collagen and polymer PLGA.

Both collagen and PLGA have been successfully used to repair damaged nerves in the laboratory, but this success has not transferred to patients in the clinic.

The CÚRAM study results supported the idea that the success of attempts to regenerate damaged nerves is dependent on the graft material used.

The different impact of graft material had been shown by many previous studies but this CÚRAM study provides a clearer understanding of how the body responds to collagen and PLGA grafts specifically.

According to the researchers, this paves the way for the development of specific nerve regeneration strategies based on the biomaterial used.

The study focused on a non-critical nerve injury and did not incorporate the effect of increasing gap distance on the regenerative response.

Male & Female brains not different; why sleeping naked is good for health; anti-cancer nanorobots built; Hawking proved right about ‘Black Holes’

nanorobots

Contrary to popular belief, Men are not from Mars and women from Venus, at least when it comes to the human brain. Neuroscientists believe that the differences between male and female brains are the result of what society expects each sex to be good at.

If you need naked with your partner every night, scientists have good news for you. This practice boosts the immune system, reduces infections, and helps establish natural body rhythms, and all of his is beneficial to our health.

Scientists in Montreal have unleashed tiny nano-robots, made up largely of DNA material, which can carry drugs to where they needed inside cancer tumours. This provides a potentially more effective cancer treatment than existing therapies, which can kill healthy cells, and can’t get access inside tumours.

Black Holes are swirling cosmic whirlpools, with enormous gravitational power that suck everything, including light, and destroys it. However, Stephen Hawking predicted that not quite everything would be destroyed and some radiation, ‘Hawking radiation’, would escape. A new experiment confirms Hawking’s theory.

Teenage Girls Texting

Teenage girls are more likely to become compulsive texters than boys

Good memories could be implanted by ‘synapse surgeons’ in the future, and bad memories erased, according to a leading memory scientist.

Girls are more likely to become compulsive texters than boys, and to suffer academically as a result.

Captain Scott Kelly, US astronaut returned to Earth this week after 340 days on the International Space Station.

Scientists will compare his blood, saliva and other bodily tissues with his identical twin, Mark, also an astronaut, who remained on the ground.

The idea is to determine the impact of long duration space missions, in advance of the NASA-led manned mission to Mars in the 2030s.

Half the world’s population will be short-sighted by 2050, with one fifth, or an estimated 1 billion people, having a severe short-sightedness, scientists predict.

 

Justification for torture is scientifically bogus, according to Irish neuroscientist

The justification for torture in Northern Ireland, Iraq, Algeria and many other places has always been that, while distasteful, it produces results that save innocent lives.

This premise is scientifically bogus, according to TCD neuroscientist Professor Shane O’Mara. The neuroscientist details exactly why in his new book ‘Why Torture Doesn’t Work‘ (Harvard University Press)

Torture Doesn't Work

Full body transplants in two years; true artificial intelligence draws closer; the ‘ad men’ get literally inside our heads

Neuromarketing

Advertisers now have the power to see how the brain reacts to commercial messages (Credit: http://www.sketptikai.com)

Imagine if advertisers could literally get inside our heads, and see how the brain reacts to various selling messages?

Well it’s  happening and it’s called neur0-marketing. The ad men now have access to our private thoughts, thanks to sophisticated brain scanning and thought-reading technologies.

Meanwhile, an Italian surgeon has stated that full body transplants will be available inside two years. This is thanks to advances in surgical techniques and drugs that suppress a bodily reaction to a new head.

It’s expected that such transplants will be outlined in the USA and the EU, but the surgeon believes that if it is possible, then people that have no other option to live, but to find a new body will make use of the technique.

The decade long drive towards true Artificial Intelligence, where software can learn like a child and develop its own strategies, appears getting nearer with the development of Google’s Agent software.

What makes a psychopath? Why are some people more empathetic to others? How does mindfulness change the brain? Are parasites controlling our minds? Are infections a significant cause of mental illness in humans?

These are some of the questions myself Sean Duke, and Colette Kinsella, explored here in episode 1 of What’s It All About? on RTE Radio 1
