Melissa Saenz and Christof Koch Show that Sight Recovery After Blindness Offers New Insights on Brain Reorganization

05-29-08

Studies of the brains of blind persons whose sight was partially restored later in life have produced a compelling example of the brain's ability to adapt to new circumstances and rewire and reconfigure itself. The research, conducted by postdoctoral researcher Melissa Saenz along with Christof Koch, the Lois and Victor Troendle Professor of Cognitive and Behavioral Biology and professor of computation and neural systems, and their colleagues, shows that the part of the brain that processes visual information in normal individuals can be co-opted to respond to both visual and auditory information.

Athanassios Siapas and Evgueniy Lubenov Reveal the Driving Factor in the Brain's Self-regulation

04-18-08

Using computer models of neuronal circuits and experiments on live rats, Athanassios Siapas, Assistant Professor of Computation and Neural Systems, and his postdoctoral researcher Evgueniy Lubenov are revealing the curious mechanism by which the brain spontaneously tips itself toward a state balanced between order and chaos. The driving factor in the brain's self-regulation, they say, is the timing of neural pulses. "Networks self-organize to an intermediate state, in between the two extremes," Siapas says.

Christof Koch and Colleagues Find Pupil Dilation Marks Decision Making

02-12-08

Christof Koch, the Troendle Professor of Cognitive and Behavioral Biology and Professor of Computation and Neural Systems, and his colleagues, have found that changes in pupil diameter correspond to the moment when a simple decision is made. The pupil, which is about 2 mm wide in bright light, dilated by as much as 1 mm at that moment--a change that, in theory, could be noticeable to a casual observer. [Caltech Press Release]

Matthew Lew Receives Newport and Spectra-Physics Research Excellence Travel Award

01-23-08

Electrical engineering undergraduate student, Matthew Lew, has received the a Newport and Spectra-Physics Research Excellence Travel Award at the SPIE Photonics West Conference, held January 23, 2008 in San Jose. He won the award for his work on "Two-dimensional differential interference contrast microscopy based on four-hole variation of Young's interference" conducted in Changhuei Yang's Biophotonics Laboratory. This award is typically given to graduate students for outstanding research, Matthew Lew stands out in this year's batch of recipients as he is the only undergraduate to receive the prize.
