Can we replicate basic brain functions? In this talk, computational neuroscientist and Harvard Professor, David Cox reveals how vision works in the brain and explains how his research can help pave the way towards prosthetics that restore or enhance brain function, as well as enabling the design of computer algorithms that “see” like we do.

A new study, which may have implications for approaches to education, finds that brain mechanisms engaged when people allow their minds to rest and reflect on things they’ve learned before may boost later learning.
Sixty-nine scientists at Stanford University and other institutions issued a statement that the scientific track record does not support the claims that so-called “brain games” actually help older adults boost their mental powers.
A new study examines link between brain cortex and food buying habits.
New research shows for the first time that engaging brain areas linked to so-called “off-task” mental activities (such as mind-wandering and reminiscing) can actually boost performance on some challenging mental tasks. The results advance our understanding of how externally and internally focused neural networks interact to facilitate complex thought.
We are more likely to be receptive to good news than bad, and researchers have gone some way to explaining why we prefer to look on the bright side.
Researchers have found a definitive link between gait – the way someone walks – and early changes in cognitive function in people with Parkinson’s disease. And the findings, published in the journal Frontiers in Aging Neuroscience could mean that gait may be used as an early warning sign to help predict the development of cognitive impairment and dementia in Parkinson’s.
Exercise is one of the best ways to protect against dementia in later life and the earlier you start, the greater the effect, research suggests.
Finally this week, a previously unknown mechanism through which the brain produces new nerve cells after a stroke has been discovered at Lund University and Karolinska Institutet in Sweden. The findings have been published in the journal Science.
A Buddhist monk—this one with a doctorate in cell biology—has teamed with two prominent neuroscientists to present the latest findings on what meditation does to the brain and how those changes to neural circuits have some of the trappings of what might be labeled a perfect drug—Prozac-like muting of depression symptoms or prophylaxis against PTSD (just two on the list). In this video Richard Davidson, Ph.D., presents their research at Stanford University in a talk entitled, The Emergence of Contemplative Neuroscience.
Researchers have identified what is likely a key genetic pathway underlying bipolar disorder, a breakthrough that could lead to better drugs for treating bipolar affective disorder, as well as depression and other related mood disorders.
Hubs are locations in the brain where different networks come together to help us think and complete mental tasks. Now, a new study offers a fresh view of how injury affects the brain. It finds damage to brain hubs disrupts our capacity to think and adapt to everyday challenges more severely than damage to locations distant from hubs.
Neuroscientists have found that a gene mutation that arose more than half a million years ago may be key to humans’ unique ability to produce and understand speech.
A paper published this month in Biological Psychiatry shows that children who spent their early years in these institutions have thinner brain tissue in cortical areas that correspond to impulse control and attention.
Researchers have found vital new evidence on how to target and reverse the effects caused by one of the most common genetic causes of Parkinson’s.
Neuroscientists and engineers at North Carolina’s Duke University have pioneered a method with which the effects of transcranial magnetic stimulation (TMS) on the brain can be measured. The Duke team has made it possible to measure the response of a single neuron to an electromagnetic charge–something that has not before been possible. The work offers the potential to improve and initiate novel TMS therapy approaches.
I will be giving a talk on drugs, addiction and the brain for alcohol and drug awareness week which is scheduled to take place November 17th – 21st 2014.
This talk will explain how the brain basically works and how and where drugs such as heroin, cocaine, alcohol and cannabis work in the brain. The concept of “reward” which is the property that is characteristic of many addictive drugs will also be discussed. The talk will be useful for those interested in learning about the diverse effects of drugs of abuse on the brain.
Details: Wednesday 19th November 7-9 pm at the Absolute Hotel, Limerick– Abbey Suite 3. Free Admission.
When musicians play, what is happening inside their brains? Scientists at Berlin’s Max Planck Institute for Human Development have discovered that while performing together, their neurological activity goes into a kind of synchronization mode – almost as though they were connected by a wireless network.
Like conducting an errant orchestra to play together, researchers are guiding processes that go awry in multiple sclerosis to repair themselves.
For the first time, scientists have discovered the exact mechanism rabies uses to efficiently enter the central nervous system, where it erupts in a toxic explosion of symptoms.
Neurons in human skin perform advanced calculations, previously believed that only the brain could perform.
Brain scans of college students have shed light on why people learn more effectively when their curiosity is piqued than when they are bored stiff. Researchers in the US found evidence that curiosity ramped up the activity of a brain chemical called dopamine, which in turn seemed to strengthen people’s memories.Students who took part in the study were better at remembering answers to trivia questions when they were curious, but their memories also improved for unrelated information they were shown at the same time.The findings suggest that while grades may have their place in motivating students, stimulating their natural curiosity could help them even more.
Researchers have discovered that T-cells – a type of white blood cell that learns to recognize and attack microbial pathogens – are activated by a pain receptor.
Quantitative tools dissect how two genes mutated in early-onset Parkinson’s disease collaborate in flagging damaged mitochondria.
A new study suggests a neural link between curiosity, motivation, and memory.
In a recent study published in the journal PLOS One, scientists uncovered a new pathway by which the brain uses an unusual steroid to control blood pressure. The study also suggests new approaches for treating high blood pressure and heart failure
Research using state-of-the-art eye-tracking technology has found that people suffering from chronic pain pay more frequent and longer attention to pain-related words than individuals who are pain-free.
The traditional view is that learning is based on the strengthening or weakening of the contacts between the nerve cells in the brain. However, this has been challenged by new research findings from Lund University in Sweden. These indicate that there is also a third mechanism – a kind of clock function that gives individual nerve cells the ability to time their reactions.
And finally this week, how your brain decides who to make friends with when you start university.
Psychiatrist Nora Volkow, chemist Kim Janda, and neuroscientists Eric Nestler and Amir Levine explain the latest thinking in the science of addiction.
Brain imaging pioneer Nancy Kanwisher, who uses fMRI scans to see activity in brain regions (often her own), shares what she and her colleagues have learned: The brain is made up of both highly specialized components and general-purpose “machinery.” Another surprise: There’s so much left to learn.
