A study was undertaken to investigate the response of the rodent somatosensory barrel cortex to single-whisker, near-threshold vibrissal stimuli. Cortical responses to controlled whisker deflections were recorded by (i) conventional multi-unit extracellular recording within the cytochrome oxidase rich barrels centers and the interbarrel septa, and (ii)(More)
Several groups have described using intrinsic optical imaging to form images of activity patterns in the cortex. Because the signal is small, the general approach has been to use expensive camera equipment with a high dynamic range to make these measurements. However, by using signal averaging to compensate for lower dynamic range, images can be obtained(More)
A study was undertaken to investigate the response of the rodent somatosensory barrel cortex to paired-whisker stimuli. Cortical responses to controlled whisker deflections were recorded by (i) conventional multi-unit extracellular recording within the cytochrome oxidase rich barrels centers, and (ii) intrinsic signal optical imaging, a technique that(More)
One technique for studying the cortex entails mapping the distribution of neuronal response properties across a cortical zone. In sensory cortex, 'receptive fields' are arranged in an orderly way such that they form a topographical representation, or 'map', of the sensory surface on the cortex. Detailed maps can be constructed by making many microelectrode(More)
EXP is a Macintosh program for doing quantitative neurophysiology. It supports signal design, simultaneous signal output and data collection, spike sorting, histogram production, and many other analysis features. The hierarchical structure used to design protocols provides a straightforward method for designing complex experiments. The degree of automation(More)
