Memory traces are believed to be ensembles of cells used to store memories. To visualize
memory traces, we created a transgenic line that allows for the comparison between cells …

Fear memories guide adaptive behavior in contexts associated with aversive events. The
hippocampus forms a neural representation of the context that predicts aversive events. …

Transforming synaptic input into action potential output is a fundamental function of neurons.
The pattern of action potential output from principal cells of the mammalian hippocampus …

Virally based transsynaptic tracing technologies are powerful experimental tools for neuronal
circuit mapping. The glycoprotein-deletion variant of the SAD-B19 vaccine strain rabies …

Mossy cells in the hilus of the dentate gyrus constitute a major excitatory principal cell type in
the mammalian hippocampus; however, it remains unknown how these cells behave in vivo…

Diverse computations in the neocortex are aided by specialized GABAergic interneurons (INs),
which selectively target other INs. However, much less is known about how these …

The importance of mitochondria for neuronal function is evident by the large number of
neurodegenerative diseases that have been associated with a disruption of mitochondrial …

Hippocampal interneurons receive GABAergic input from the medial septum. Using two-photon
Ca 2+ imaging of axonal boutons in hippocampal CA1 of behaving mice, we found that …

The substantia nigra pars reticulata (SNr) plays a key role in basal ganglia function. Projections
from multiple basal ganglia nuclei converge at the SNr to regulate nigrothalamic output. …

Sharp-wave ripples are transient oscillatory events in the hippocampus that are associated
with the reactivation of neuronal ensembles within specific circuits during memory formation. …
