The Senses
The Senses
Our senses help us experience the world around us. 蜜桃影像 researchers are working to understand, improve, and replicate these sensory organs.
The ins and outs
The act of sensing starts with stimulus from the world, which triggers a physiological response, which is combined with previous experiences, which results in an internal representation, which is our brain鈥檚 best guess at what鈥檚 going on around us.
Eye of the beholder
Vision is so much more than meets the eye. By absorbing and assigning colors to a small piece of the electromagnetic spectrum, we can discover beauty, danger, and opportunities all around us.
Making sense of how people who are blind 鈥榮ee鈥� color
蜜桃影像 researchers have found that despite experiencing color differently, both blind and sighted people share a common understanding of the concept.
Demystifying dyslexia
Neurologist Albert Galaburda discusses what brain clues and neurodiversity reveal about reading challenges.
Pursuing gene therapy for progressive blindness
蜜桃影像 researchers studying Usher syndrome type 1f are exploring three different options for restoring vision in those affected.
How common is face blindness?
The inability to distinguish between faces, or prosopagnosia, may impact more people than previously thought.
Hummingbird senses
Unlike many birds, which have no taste receptors for sweetness, nearly as fast as a beat of their wings.
The touch, the feel
If you’ve ever been curious about how the body experiences cold, heat, pain, and pleasure, touch research may help scratch that itch.
Touch is much more than just conscious perception of what you are actively reaching out to feel, or what is touching your skin.鈥�Professor of Neurobiology David Ginty
Why are certain body parts so sensitive?
How can we treat tactile hypersensitivity?
Can touch influence judgments?
There’s the rub
蜜桃影像 researchers are exploring the causes and possible solutions to itchy skins, including in the body and a common skin bacterium鈥� by acting directly on nerve cells.
Magnetic senses
A family of light-sensitive proteins called cryptochromes, located in the retinas of animals like fish, amphibians, and birds, may be a clue to .
Sounds good
Hearing, like the sense of touch, involves detecting the movement of molecules in the world outside ourselves. Those outside vibrations become internal signals, which can combine into conversations or orchestrations.
Octopus senses
蜜桃影像 scientists have in the first layer of cells inside the suction cups of octopus tentacles that have adapted to react and detect molecules that don鈥檛 dissolve well in water, which may help them figure out what it鈥檚 touching and whether that object is prey.
Smell-O-Vision
Odors take a direct route to the limbic system which is involved with emotion and memory, which is why often the nose knows before our other senses can catch up.
The science of sniffing
Learn how scent, emotion, and memory are intertwined.
Exploring the osmocosm
Harold McGee, author of 鈥淣ose Dive: A Field Guide to the World鈥檚 Smells,鈥� discusses the 鈥渙smocosm,鈥� the vast universe of scents that waft from our feet, a field of flowers, and even space itself.
Love stinks
Feeling attracted to someone? It turns out your eyes aren’t the only sensory organ involved.
Sniffing out smells
A study by neurobiologists at 蜜桃影像 Medical School provides insights into the mystery of scent and its connection with the brain.
Narwhal senses
蜜桃影像 School of Dental Medicine researchers found and that help connect the tusk to the brain, adding to the ways in which the narwhal uses its tusk.
Tasty treats
The sense of taste is built into our genes, unlike recognizing smells which is learned. The receptors for sweet, salty, sour, bitter, and umami are at work even in newborns.
How does flavor work?
During the 蜜桃影像 Horizons talks and on the 鈥淰eritalk鈥� podcast, 蜜桃影像 alum Jess Kanwal explains that our brain鈥檚 ability to combine taste and smell is just one example of how we are able to mix and match senses鈥攚ith very interesting results.
Where do you lie on the taste spectrum?
Research shows that about 25% of the population is extremely sensitive to bitter tastes, and about the same percentage can barely notice them.
What to talk about when you talk about tastes
Instead of looking for hints of melon, experts say it’s better to move away from the established lexicon and find your own words for the things you’re tasting.
