Smelling your food makes you fat

Our sense of smell is key to the enjoyment of food, so it may be no surprise that in experiments at the University of California, Berkeley, obese mice who lost their sense of smell also lost weight. What’s weird, however, is that these slimmed-down but smell-deficient mice ate the same amount of fatty food as […]

Does my sense of smell make me look fat? In mice, the answer seems to be yes

Having an exceptionally keen sense of smell would seem to be an unmitigated blessing: It can provide early warning of dangers, detect the presence of an attractive mate, and enhance the gustatory delight of a delicious meal. But when you’re a mouse (or, perhaps, a human) and fattening food is all around, a new study finds that […]

Mice shed weight when they can’t smell—but not because they stop eating

When you have a stuffy nose, a slice of freshly baked apple pie tastes like mush. But not being able to smell your food could have a surprising effect on your metabolism, potentially helping you remain thin even when you eat fatty foods, a new study in mice suggests. “This is a very exciting study, […]

Brain Changes Accompany Development of Metamemory from Childhood to Adolescence

Being able to assess our own memories helps us to avoid errors and prompts us to collect more information to fill the gaps. Psychologists know that this ability is present in elementary school-age children. Now a new study shows how this “metamemory” improves from childhood through adolescence, with accompanying changes in brain structure. The work […]

A mouse’s view of the world, seen through its whiskers

Mice, unlike cats and dogs, are able to move their whiskers to map out their surroundings, much as humans use their fingers to build a 3D picture of a darkened room. UC Berkeley researchers have for the first time reconstructed the whisker map a mouse creates of its surroundings in order to navigate its world, […]

Kaoru Saijo awarded Pew scholar grant

Kaoru Saijo, an assistant professor of molecular and cell biology, will receive a four-year grant to investigate the role of the brain’s immune cells, called microglia, in the development of depression. Saijo will seek to determine whether mutations that alter gene activity in microglia lead to a sustained inflammatory response in the brain, whether such […]

Advancements to functional imaging technique result in ultra-high resolution capture of human cortical columns

Despite numerous advances in fMRI technology, most components are optimized for the entire body. This makes safe, ultra-high resolution (UHR) imaging of columnar organization throughout the cortex of the human brain nearly impossible. At the University of California, Berkeley, Dr. David Feinberg and colleagues applied updates to magnetic gradients, receiver arrays, and pulse sequences of […]

Recent PhD graduate Brian Isett studies how tactile textures and shapes are represented in the brain

  The building blocks of experience Brian Isett has long been interested in the big, difficult questions about perception. His drive to understand individual experience led him to study philosophy and write poetry, but that was not enough. He wanted answers. Rather than throwing up his hands, he rolled up his sleeves and started to […]

Dressmakers found to have needle-sharp 3D vision

Haute couture can be credited for enhancing more than catwalks and red carpets. New research from UC Berkeley suggests that the 3D or “stereoscopic” vision of dressmakers is as sharp as their needles. Stereoscopic vision is the brain’s ability to decode the flat 2D optical information received by both eyes to give us the depth […]
