How does the visual system process information from the outside world and what are the rules that constrain the evolution of sensory systems? We discuss these questions with Dale Purves, Geller Professor of Neurobiology at Duke University. Continue reading
I awoke this morning to a ferocious lightning storm. The house shook from thunderous booms. The predawn darkness blanched in blazing white flashes. Lightning is impressive; especially in contrast to the feeble bioelectricity generated by the body’s nerve cells. Or is that just an illusion? Neuroscientist Michael Persinger has done some back-of-the-envelope calculations that may surprise you.
NEURO.tv starts the season with an amazing discussion with Katherine L. Bryant about the visual cortex in primates and the anatomical differences found between the brains of different primates. Continue reading
Guys who need it have Viagra; Ladies with the similar needs have nothing now that the FDA has denied approval of a new drug, flibanserin, which would treat sexual dysfunction in women. What’s interesting from a neuroscience perspective is how the drug works. What’s interesting from a social perspective is how difficult it is to address this medical concern in women pharmacologically. Continue reading
I’ll never forget it. They strapped electrodes to my wrist, cranked up a black dial on a frightening electronic device encrusted with switches and knobs, and shocked me repeatedly with jolts of electricity. Continue reading
In this episode, we talk about grid cells and place cells. These fascinating neurons process information that relate to where an animal is located in space. They are believed to play important roles in navigating the environment. Our guests are May-Britt and Edvard Moser from the Norwegian University of Science and Technology. Continue reading
David H. Hubel, whose work unveiled fascinating brain processes that underlie our sense of vision, died last month at the age of 87.
Hubel’s parents were Americans, living in Detroit, Michigan. His father had a job in Windsor, Ontario. Tired of commuting across the Detroit River, he moved to Canada, where David Hubel was born. During his childhood David spent considerable effort learning to play the piano, and later the flute. In 1929, the family moved to Montreal where David Hubel grew up. Continue reading
