When, during the experiment, the connection between mouse movements and pointer movements on the screen is perturbed, the participants should experience a breakdown in their smooth coping and, consequently, experience the tool as unready-to-hand.
Studies by geneticist Gerard Karsenty at Baylor College of Medicine in Houston confirmed the connection in mice, showing that leptin-deficient mice build up their bones as well as their body weight (ScienceNOW, 18 January, 2000).
Imaging efforts at the Center for Brain Science will visualize the dynamic re-wiring of connections in mouse models to provide further insight for translational research into disorders of critical period development at Children's Hospital Boston.
Jarvis and colleagues found a rudimentary indirect connection in mice between the two, absent in chimpanzees and monkeys.
Deleting a gene called Sema5A, which has been linked to autism in humans, causes neurons to form more connections in mice, and also alters how these mutant mice interact with other mice.
Kohl and colleagues recently uncovered the organizational principles of hypothalamic galanin neurons and their connections in mice.
By looking at the relative strength of the currents passing through two glutamate receptors known to indicate synaptic strength, Tye discovered that different neural connections in mice were reinforced depending on whether a particular stimulus was linked to a reward or a threat.
Now scientists at the Massachusetts Institute of Technology MITT) have taken a first step toward designing such a treatment: They have identified a protein that stimulates regrowth of severed eye-brain connections in mice, according to a report in tomorrow's issue of Nature.
In order to keep both a transducer-cable connection and the mouse head above water, we constructed an imaging platform to diagonally secure the mouse.
After 4 weeks of connection to young mice, the five old mice's heart tissue had thinned and softened, looking just as spry and supple as the 2-month-olds'.
