- MIT shows how brain tells glossy from grainy surfaces
04-19-2007 · Massachusetts Institute of Technology (MIT)
A team of researchers from MIT and NTT Lab in Japan reveal how the brain responds to surface textures. Their findings show that the perception of reflectance and gloss may be coded by neurons that respond differentially to light and dark spots.

- Experience affects new neuron survival in adult brain; study sheds light on learning, memory
03-22-2007 · EurekAlert!
Experience in the early development of new neurons in specific brain regions affects their survival and activity in the adult brain, new research shows. How these new neurons store information about these experiences may explain how they can affect learning and memory in adults.

- A light beam for manipulation of cells on chips
10-31-2007 · Massachusetts Institute of Technology (MIT)
In a feat that seems like something out of a microscopic version of Star Trek, MIT researchers have found a way to use a "tractor beam" of light to pick up, hold and move around individual cells and other objects on the surface of a microchip.

- Carnegie Mellon study reveals that odor discrimination is linked to the timing at which neurons fire
11-07-2006 · EurekAlert!
Timing is everything. For a mouse trying to discriminate between the scent of a tasty treat and the scent of the neighborhood cat, timing could mean life or death. In a striking discovery, Carnegie Mellon University scientists have linked the timing of inhibitory neuron activity to the generation of odor-specific patterns in the brain's olfactory bulb, the area of the brain responsible for distinguishing odors.

- Force, not light, provides images of cell receptors
06-13-2007 · Massachusetts Institute of Technology (MIT)
An MIT team has observed and measured the rate at which individual molecules join and separate from receptors on the cell surface by measuring the force generated by these cell surface interactions. The interactions are not visible with traditional light microscopy.

- MIT reports key pathway in synaptic plasticity
05-21-2007 · EurekAlert!
Scientists are keenly studying how neurons form synapses -- the physical and chemical connections between neurons -- and the "pruning" of neural circuits during development, not least because synaptic abnormalities may partially underlie many developmental and neurodegenerative diseases. Several key molecules are involved in normal synaptic formation, but their interactions are not well understood. Now MIT neuroscientists have pieced together a direct linear pathway connecting three such molecules.

- The birth and death of dopamine neurons: A new model for neurodegeneration
12-10-2007 · EurekAlert!
The connection between development and neurodegeneration is emphasized via a new mouse knockout of a transcription factor that is critical for dopamine neuron specification, which produces a late-onset, asymmetric degenerative condition in a manner very similar to human Parkinson's disease.

- Researchers use brain scans to predict when people will buy products
01-03-2007 · EurekAlert!
For the first time, researchers have used functional magnetic resonance imaging (fMRI) to determine what parts of the brain are active when people consider whether to purchase a product and to predict whether or not they ultimately choose to buy the product. The study appears in the journal Neuron and was co-authored by scientists at Carnegie Mellon University, Stanford University and the MIT Sloan School of Management.
