Behavioral correlates of hippocampal single unit activity in rats

Spatial and behavioral correlates of hippocampal neuronal activity.

The firing rate of hippocampal neurons in rats was related both to spatial location and to multiple behavioral variables as rats performed 2 kinds of tasks that rely on hippocampal function: a spatial navigation task similar in performance demands to the radial-arm maze task and a simultaneous cue odor-discrimination task. In the place task, most cells had distinct single or multiple place fiel...

Hippocampal unit activity after transient cerebral ischemia in rats.

Single unit activity of CA1 and CA3 neurons in the hippocampus was recorded in rats 1, 2, or 3 days after 10 minutes of transient cerebral ischemia induced by the clamping of both carotid arteries combined with hypotension. In addition, paired pulse inhibition/facilitation of the CA1 population spike was examined on Day 2 using two successive stimuli of the contralateral CA3 region delivered at...

Studies on single neurons in dorsal hippocampal formation and septum in unrestrained rats. I. Behavioral correlates and firing repertoires.

Cue-sampling and goal-approach correlates of hippocampal unit activity in rats performing an odor-discrimination task.

Several techniques previously used to describe behavioral correlates of hippocampal unit and slow-wave activity are combined in a single odor-discrimination paradigm. Rats repetitively performed a sequence of behaviors during each trial: approach to a stimulus-sampling port, investigatory sniffing of the odor cue, orientation and approach toward a separate reward location, and water reward cons...

Atrazine-induced Hippocampal Degeneration and Behavioral Deficits in Wistar Rats: Mitigative role of avocado oil

Background: Glutamate is essential to learning and memory as an excitatory neurotransmitter. This study evaluated the atrazine effect on the hippocampus and examined the mitigative role of avocado oil against the neuronal degeneration and behavioral deficits in Wistar rats. Methods: Fifty adult male Wistar rats were divided into four groups of ten. Group 1 (controls) received 0.5 ml distilled ...
