Topic: tetrode technique

In contemporary neuroscience, a traditional representation approach is complemented by growing interest in neuronal dynamics. We used tetrode technique to study in hippocampal CA1 activity how spatial representations and neuronal dynamics are affected by environmental and task complexity and by rats’ prior learning experience. Each neuronal ensemble was recorded in four recording sessions: a session where a rat was exposed to a stationary rat-sized robot and a session with the robot slowly moving, were flanked by two sessions without the robot. Some rats were trained to avoid a location define
