Axonal arbors of principal neurons form the backbone of neuronal networks in the mammalian cortex. Three-dimensional reconstructions of complete axonal trees are invaluable for quantitative analysis and modeling. However, digital data are still sparse due to labor intensity of reconstructing these complex structures. We augmented conventional tracing(More)
Work in progress toward the creation of a " cultured neuron probe " is described. This is a silicon structure similar to that for a multielectrode probe, but with embedded neurons which are intended to grow out and integrate with the neurons of a host nervous system into which the probe has been inserted. Each probe neuron is in close proximity to an(More)
In rodent hippocampus, neuronal activity is organized by a 6-10 Hz theta oscillation. The spike timing of hippocampal pyramidal cells with respect to the theta rhythm correlates with an animal's position in space. This correlation has been suggested to indicate an explicit temporal code for position. Alternatively, it may be interpreted as a byproduct of(More)
are incorrectly labeled. The symbols for control (HCN1 f/f) and forebrain-restricted HCN1 knockout (HCN1 f/f,cre) are reversed. The closed symbols in these panels correspond to data from HCN1 f/f,cre mice, whereas the open symbols refer to data from HCN1 f/f mice. Note that throughout the rest of the paper, closed symbols refer to data from HCN1 f/f mice(More)
Neostriatal cholinergic interneurons are believed to play an important role in reinforcement mediated learning and response selection by signaling the occurrence and motivational value of behaviorally relevant stimuli through precisely timed multiphasic population responses. An important problem is to understand how these signals regulate the functioning of(More)

Involvement of nitric oxide in depolarization-induced suppression of inhibition in hippocampal pyramidal cells during activation of cholinergic receptors. Identification of the sites of 2-arachidonoylglycerol synthesis and action imply retrograde endocannabinoid signaling at both gabaergic and glutamatergic synapses in the ventral tegmental area.(More)
postsynaptic receptors, as a form of synaptic plasticity, to be a key element in associative memory formation. Circuit mechanisms of memory. By using molecular tagging techniques, we estimate that about a third of lateral amygdala neurons undergo plasticity during the formation of a memory driven by a single conditioning block. Because not all synapses on a(More)
