7. Plenary Session: Understanding the Physiology of Volition: What is free about free will?
Mark Hallett, MD, of the National Institute of Health Human Motor Control Section discusses free will and intentionality as it relates to movement. He cites research indicating that the genesis of movement is often unconscious and temporarily uncoupled from the senses of willing and agency. This was presented October 25, 2012 at Brain Matters 3, in Cleveland, Ohio. The video was produced by the Cleveland Clinic Foundation NeuroEthics Program and the Neurological Institute.

Society for Integrative and Comparative Biology to Gather in San Francisco in January 3-7, 2013
WASHINGTON, Dec. 21, 2012 /PRNewswire-USNewswire/ --The Society for Integrative and Comparative Biology (SICB), one of the oldest and most prestigious interdisciplinary biological organizations, will hold its annual meeting at the Hilton San Francisco, Union Square, in San Francisco, CA, from January 3 to 7, 2013. More than 1,500 scientists will present the latest research on animal ecology, evolution, physiology, neurobiology, and biomechanics, offering journalists a rich assortment of news and feature possibilities.
This year at SICB, experts from a wide array of different disciplines will convene at the meeting to discuss cutting edge science on multiple topics; the following symposia may be of particular interest:
Besides these symposia, SICB researchers will be discussing many diverse topics such as how animals tell what time and month it is, how they cope with a changing environment, and how they can pass information about the environment to their descendantswithout genes. Along with these, scientists will present the latest results on the mechanics of walking, swimming, hopping, jumping, and flying, the evolution of body shape, behavior, symbiosis, and ecological interactions, and many other topics.
When Predators Attack: Sensing and Motion in Predator-Prey Interactions
Predators and their prey are engaged in a constant battle, in which finely tuned sensory abilities and split-second reaction times can mean the difference between life and death. Researchers are using cutting edge techniques and amazing high speed video footage to investigate how predators and prey process sensory information and translate it into action. Although we know a lot about how many predators and prey interact to cause populations to rise and fall, we don't know very much about how two animal opponents sense each other and react, leading to some animals getting eaten and some escaping. Through the use of cutting-edge techniques, neurobiologists, ecologists, and biomechanics researchers have recently made this a tractable area of research. The goal of this symposium is to highlight new findings that are advancing our understanding of sensing and movement in predator-prey interactions, an exciting new frontier of cross-disciplinary research.
Vertebrate Land Invasions: Past, Present, and Future
How did the first fishes start to climb out of the ocean and live on land? These early land animals, the ancestors of all modern vertebrates on land, faced numerous challenges, including moving and supporting themselves, breathing, eating, sensing, and not drying out. Although we can't study the ancients directly, there are modern species of fish and amphibians that come out on land and face many of the same challenges as the early pioneers did. These modern animals may help us to understand the early transition to land. The symposium brings together a diverse array of scientists from different fields such as paleontology, physiology, behavior, biomechanics, and robotics, to highlight their research in topics related to vertebrate land invasions.
Phenotypic Plasticity and the Evolution of Gender Roles
In many animals, gender roles are much more fluid than they are in humans. Some animals start off male and later become female, or the other way around; others can be male and female simultaneously. This is an example of phenotypic plasticity, the remarkable ability of some organisms to radically change their appearance (and even their sexuality) in response to environmental cues. This symposium will be a window into the fascinating world of animal sexuality, with presentations on the genetics, evolution, ecology, and physiology of gender in organisms ranging from barnacles to snapping turtles.

Integrative and Comparative Biologists to Discuss Latest Research
NEW YORK (Reuters Health) - Kids given a combination of cheese and vegetables will eat only about a quarter as many calories as those given potato chips, according to a new study.
"Like it or not, children like foods that are energy-dense and not those that are nutrient-rich. That is because children are still growing. That is basic physiology," said Adam Drewnowski, director of the Nutritional Sciences Program at the University of Washington, who was not part of the study.
The findings may not be surprising, but they suggest that swapping out potato chips for cheese or vegetables then might help reduce the amount of calories kids eat at snack time, said Adam Brumberg, one of the authors of the study and the deputy director of the Food and Brand Laboratory at Cornell University.
"If you put into the rotation (healthier snacks) you can have a significant impact on weekly caloric intake," he suggested.
The study, which was funded in part by the cheese maker Bel Brands USA, involved 183 kids in 3rd through 6th grade.
Each of the kids was put in a room to watch TV and eat a snack - 45 kids were given potato chips, 36 were offered cheese, 59 were given raw vegetables and 43 were given cheese and vegetables.
After 45 minutes the researchers measured how much food the children had eaten.
They found that kids in the chip group ate by far the most calories - 620 on average.
Kids ate 200 calories of cheese, 60 calories of vegetables and 170 calories of the combination cheese-and-vegetables snack.
"Children tend to eat the foods they like - and one measure of preference is the amount eaten. So chips and cheese beat raw vegetables hands down. Why am I not surprised?" said Drewnowski in an email to Reuters Health.
London, December 17 (ANI): A new study found that sons of male rats exposed to cocaine are resistant to the rewarding effects of the drug, suggesting that cocaine-induced changes in physiology are passed down from father to son.
The study was carried out by researchers from the Perelman School of Medicine at the University of Pennsylvania and Massachusetts General Hospital (MGH).
"We know that genetic factors contribute significantly to the risk of cocaine abuse, but the potential role of epigenetic influences - how the expression of certain genes related to addiction is controlled - is still relatively unknown," said senior author R. Christopher Pierce, PhD, associate professor of Neuroscience in Psychiatry at Penn.
"This study is the first to show that the chemical effects of cocaine use can be passed down to future generations to cause a resistance to addictive behavior, indicating that paternal exposure to toxins such as cocaine can have profound effects on gene expression and behavior in their offspring," he commented.
In the current study, the team used an animal model to study inherited effects of cocaine abuse. Male rats self-administered cocaine for 60 days, while controls were administered saline. The male rats were mated with females that had never been exposed to the drug. To eliminate any influence that the males' behavior would have on the pregnant females, they were separated directly after they mated.
The rats' offspring were monitored to see whether they would begin to self-administer cocaine when it was offered to them. The researchers discovered that male offspring of rats exposed to the drug, but not the female offspring, acquired cocaine self-administration more slowly and had decreased levels of cocaine intake relative to controls.
Moreover, control animals were willing to work significantly harder for a single cocaine dose than the offspring of cocaine-addicted rats, suggesting that the rewarding effect of cocaine was decreased.
In collaboration with Ghazaleh Sadri-Vakili, MS, PhD, from MGH, the researchers subsequently examined the animals' brains and found that male offspring of the cocaine-addicted rats had increased levels of a protein in the prefrontal cortex called brain-derived neurotrophic factor (BDNF), which is known to blunt the behavioral effects of cocaine.
"We were quite surprised that the male offspring of sires that used cocaine didn't like cocaine as much," said Pierce.
"While we identified one change in the brain that appears to underlie this cocaine resistance effect, there are undoubtedly other physiological changes as well and we are currently performing more broad experiments to identify them. We also are eager to perform similar studies with more widely used drugs of abuse such as nicotine and alcohol," he noted.

Reflexes play an important role in human physiology and the ways in which the body adapts to different stimuli. Reflexes have been adapted over time to ensure survivability and fitness. In this video, we cover two reflexes that can be commonly associated to college students in the United States. The baroreflex has been adapted physiologically to compensate for the sudden change in blood pressure throughout the body. This response occurs in order for the human body to meet critical metabolic demands and prevents the possible health risks that could occur without this reflex. When the body senses an extreme drop in blood pressure, receptors located in the neck and aorta send signals to increase heart rate and dilate the blood vessels. This increases the blood flow and insures that enough oxygen is carried to various body tissues. In the video, a student experiences a failure in the baroreflex #39;s ability to compensate for the sudden change in blood pressure taking place when the student stands. The fight or flight response is an important process involved in rapidly adjusting to dangerous situations. When the body senses danger, the adrenal gland secretes hormones that can be delivered to the blood and initiate a life-saving response. Some of the ways in which the body responds to these hormones involves the dilation of the pupils, a rise in heart rate, and constriction of blood vessels. As a result, changes taking place in the body are regulated in order to avoid danger. The ...From:DreyerJakeViews:41 6ratingsTime:03:43More inPeople Blogs
