متن کاملHidden Depths in the Hippocampal Circuitry
Danielson et al. (2016) use calcium imaging in mice performing a treadmill task to reveal differences in space-coding dynamics between deep and superficial sublayers of hippocampal CA1, suggesting how the hippocampus might encode both stable and dynamic information simultaneously.

METHODS We conducted a global patient survey using an innovative, internet-based methodology to gain insight into patient perceptions of COPD and exacerbations in a real-world sample typical of tod...
متن کاملUsing "Residual Depths" to Monitor Pool Depths Independently of Discharge
As vital components of habitat for stream fishes, pools are often monitored to follow the effects of enhancement projects and natural stream processes. Variations of water depth with discharge, however, can complicate monitoring changes in the depth and volume of pools. To subtract the effect of discharge on depth in pools, residual depths can be measured. Residual depth is the difference in de...
متن کاملHidden mortality attributable to Rocky Mountain spotted fever: immunohistochemical detection of fatal, serologically unconfirmed disease.
