Beta2 oscillations (23-30 Hz) in the mouse hippocampus during novel object recognition.
The oscillatory activity of hippocampal neuronal networks is believed to play a role in memory acquisition and consolidation. Particular focus has been given to characterising theta (4-12 Hz), gamma (40-100 Hz) and ripple (150-250 Hz) oscillations. Beyond these well-described network states, few studies have investigated hippocampal beta2 (23-30 Hz) activity in vivo and its link to behaviour. A...
متن کاملBeta oscillations in face recognition.
This report presents an analysis of the brain's beta oscillations in face recognition. We performed experiments on 26 subjects with a strategy consisting of two types of stimulations: (1) the picture of an elder anonymous lady (unknown face) and (2) the picture of the subject's own grandmother (known face). The subjects were healthy, young people between the ages of 15-32 years. Data were analy...
متن کاملObject recognition and location memory in monkeys with excitotoxic lesions of the amygdala and hippocampus.
Earlier work indicated that combined but not separate removal of the amygdala and hippocampus, together with the cortex underlying these structures, leads to a severe impairment in visual recognition. More recent work, however, has shown that removal of the rhinal cortex, a region subjacent to the amygdala and rostral hippocampus, yields nearly the same impairment as the original removal. This ...
متن کاملObject recognition memory and the rodent hippocampus.
In rodents, the novel object recognition task (NOR) has become a benchmark task for assessing recognition memory. Yet, despite its widespread use, a consensus has not developed about which brain structures are important for task performance. We assessed both the anterograde and retrograde effects of hippocampal lesions on performance in the NOR task. Rats received 12 5-min exposures to two iden...
متن کاملSlow oscillations in the mouse hippocampus entrained by nasal respiration.
Different types of network oscillations occur in different behavioral, cognitive, or vigilance states. The rodent hippocampus expresses prominent θ oscillations at frequencies between 4 and 12 Hz, which are superimposed by phase-coupled γ oscillations (30-100 Hz). These patterns entrain multineuronal activity over large distances and have been implicated in sensory information processing and me...
