Alan McStravick for redOrbit.com - Your Universe Online An international collaborative study, conducted by researchers at both KU Leuven and the Harvard Medical School, has attempted to recreate Ivan Pavlov´s famous experiment, but with a twist. Pavlov, you may know, was famous for conducting a study where a stimulus was introduced and the reward for that stimulus was slowly removed, with the aim of observing whether or not a physiological response would continue to be registered...

Conditional Training Makes Honeybees Stick Out Their Tongues

[Watch Video: Tactile Conditioning And Movement Analysis Of Honey Bees] April Flowers for redOrbit.com - Your Universe Online In the early 1900s, Ivan Pavlov discovered the conditioned response, using a ringing bell and food to trigger salivation in dogs. Pavlov would ring a bell (among other stimuli) and then deliver food to the dog. The food caused the dog to salivate. After a time, Pavlov noticed that when he rang the bell, the dog started to salivate even before the food was...

It is commonly known that, much like Pavlov's dogs salivating in response to hearing the bell they associate with dinner time, smokers feel cravings and have physiological reactions to pictures they associate with smoking. New research published in BioMed Central's open access journal BMC Neuroscience has shown that a smoker's cravings can also be trained to non-smoking related stimuli. Classical conditioning experiments link a neutral stimulus, such as a sound or a picture, to an event,...

New research examines the anxious brain during a fear conditioning task and provides insight into why some individuals may be more or less prone to anxiety disorders. The study, published by Cell Press in the February 10 issue of the journal Neuron, reveals neural mechanisms that may contribute to resilience against pathological fear and anxiety. The findings may help to direct therapeutic strategies for individuals who suffer from chronic anxiety as well as strategies that could help "at...

New research shows that children with fetal alcohol syndrome suffer deficits in both learning and memory when trained in eyeblink conditioning     * Cognitive and behavioral deficits have been found in children with Fetal Alcohol Syndrome (FAS), which is extremely difficult to diagnose    * New findings indicate that those children, when trained using classical eyeblink conditioning, suffer from deficits in both learning and memory    * Using...

The brain is capable of holding and retrieving memories for specific fears, revealing a more sophisticated storage and recall capacity than previously thought, neuroscientists have found. The study, which appears in the journal Nature Neuroscience, may have implications for treating post-traumatic stress syndrome"”as scientists begin to understand how different fears are stored in the brain, they can move toward addressing specific fear memories. The research was conducted by...

Mizzou scientists find new research on the brain and fear that could help victims of Post Traumatic Stress Disorder The brain is a complex system made of billions of neurons and thousands of connections that relate to every human feeling, including one of the strongest emotions, fear. Most neurological fear studies have been rooted in fear-conditioning experiments. Now, University of Missouri researchers have started using computational models of the brain, making it easier to study the...

Activation of two different kinds of neurons is necessary for appetitive and aversive memory recall in crickets. Researchers writing in the open access journal BMC Biology blocked octopaminergic (OA-ergic) and dopaminergic (DA-ergic) transmission and found that this resulted in the inability to recall pleasant and unpleasant memories, respectively.Makoto Mizunami (now at Hokkaido University, Japan) led a team of researchers from Tohoku University, Japan, who carried out the tests. He said,...

Fear is a powerful emotion and neuroscientists have for the first time located the neurons responsible for fear conditioning in the mammalian brain. Fear conditioning is a form of Pavlovian, or associative, learning and is considered to be a model system for understanding human phobias, post-traumatic stress disorder and other anxiety disorders.Using an imaging technique that enabled them to trace the process of neural activation in the brains of rats, University of Washington researchers...

Thanks to new imaging technology, scientists are able to see neurons that are critical to how people and animals learn from experience.Researchers at the University of Washington used a new imaging technique to examine the brains of rats that had been subjected to conditioned taste aversion training.  They were able to visualize individual neurons that were activated as a result of the experiment.  More than a century ago, Russian psychologist Ivan Pavlov conditioned his dog to...
