The light microscope is traditionally an instrument of substantial size and expense. Its
miniaturized integration would enable many new applications based on mass-producible …

In this review, we present an implantable microimaging device to observe brain activities of
small experimental animals such as mice and rats. Three categories of such devices are …

Uncovering the relationships between animal behavior and cellular activity in the brain has
been one of the key aims of neuroscience research for decades, and still remains so …

The patch-leaving problem is a canonical foraging task, in which a forager must decide to
leave a current resource in search for another. Theoretical work has derived optimal …

Measurements of the deep brain area of rodents has been one of the most important
methods to study deep brain activities, in part due to limited access of this region. In order to …

To better understand the brain function based on neural activity, a minimally invasive
analysis technology in a freely moving animal is necessary. Such technology would provide …

High quality CMOS image sensors are of great importance for LoC-Lab-on-Chip devices
based on optical measurements. The main target in these devices is to minimize the cost …

The confluence of technological advances in optics, miniaturized electronic components and
the availability of ever increasing and affordable computational power have ushered in a …

We report a head-mountable CMOS camera for recording rapid neuronal activity in freely
moving rodents using fluorescent activity reporters. This small, lightweight camera is …

Chronically monitoring cerebral activities in awake and freely moving status is very important
in physiological and pathological studies. We present a novel standalone micro-imager for …
