Functional magnetic resonance imaging (fMRI) provides a unique view of the working
human mind. The blood-oxygen-level-dependent (BOLD) signal, detected in fMRI, reflects …

Although modern techniques such as two-photon microscopy can now provide cellular-level
three-dimensional imaging of the intact living brain, the speed and fields of view of these …

By means of quantitative analysis of the tissue components in the cortex of the mouse, this
book presents an overall picture of the cortical network which is then related to various …

Perceptual learning is a lifelong process. We begin by encoding information about the basic
structure of the natural world and continue to assimilate information about specific patterns …

We present a new technique for acquiring and analyzing intrinsic signal optical images of
brain activity, using continuous stimulus presentation and data acquisition. The main idea is …

Optical imaging has revolutionized our ability to monitor brain activity, spanning spatial
scales from synapses to cells to circuits. Here, we summarize the rapid development and …

Two components of cortical circuits could mediate contour integration in primary visual
cortex (V1): intrinsic horizontal connections and feedback from higher cortical areas. To …

Many thousands of cortical neurons are activated by any single sensory stimulus, but the
organization of these populations is poorly understood. For example, are neurons in mouse …

Biological structures can be seen as collections of special devices coordinated by a matrix of
organization. Devices are dif? cult to evolve and are meticulously conserved through the …

Neurons in primary visual cortex (V1) respond differently to a simple visual element
presented in isolation from when it is embedded withina complex image. This difference, a …
