The Buzsaki Lab is proud to present a large selection of experimental data available for public access. We publicly share more than a thousand sessions (about 40TB of raw and spike- and LFP-processed data) via our public data repository. The datasets are from freely moving rodents and include sleep-task-sleep sessions (3 to 24 hrs continuous recording sessions) in various brain structures, including metadata. We are happy to assist you to use these data. Our [...]

The hippocampus constructs a map of the environment. How this “cognitive map” is utilized by other brain regions to guide behavior remains unexplored. To examine how neuronal firing patterns in the hippocampus are transmitted and transformed, we recorded neurons in its principal subcortical target, the lateral septum (LS). We observed that LS neurons carry reliable spatial information in the phase of action potentials, relative to hippocampal theta oscillations, while the firing rates of LS neurons remained uninformative. Furthermore, [...]

Conditioned place preference (CPP) is a widely used model of addiction-related behavior whose underlying mechanisms are not understood. In this study, we used dual site silicon probe recordings in freely moving mice to examine interactions between the hippocampus and nucleus accumbens in cocaine CPP. We found that CPP was associated with recruitment of D2-positive nucleus accumbens medium spiny neurons to fire in the cocaine-paired location, and this recruitment was driven predominantly by selective strengthening [...]
