Abstract/Results: RESULTS:
Using the opportunity to record parahippocampal activity with foramen ovale electrodes in epilepsy patients we examined high-frequency activity and its relation to NREM sleep-slow oscillations and sleep spindles. Parahippocampal high-frequency activity was organized into bursts which were consistently associated with interictal epileptic spikes. Ripple density was higher during Non-REM than REM sleep (p<0.001). Ripple activity distinctly decreased time-locked to slow oscillation negative half-waves in the three patients without temporal structural alterations (p<0.001), whereas in the four patients with severe mesiotemporal structural alterations this coupling was obscure. Generally, in the patients ripple activity was increased before spindle peaks and distinctly decreased after the peak (p<0.001). Coordinated occurrence of hippocampal ripples, sleep spindles and slow oscillations have already been reported in animals yet the present results provide first evidence for such a temporal coupling in humans. Our findings are consistent with the notion of a hippocampo-to-neocortical information transfer during sleep that is linked to coordinate ripple and spindle activity, and that in the intact temporal lobe is synchronized to cortical slow oscillations.

Temporal coupling of parahippocampal ripples, sleep spindles and slow oscillations in humans
Publication year: 2007

http://www.ncbi.nlm.nih.gov/pubmed/17615093
Abstract/Results: ABSTRACT:
Ripples are high-frequency oscillation bursts in the mammalian hippocampus mainly present during Non-REM sleep. In rodents they occur in association with sharp waves and are grouped by the cortical slow oscillation such that, in parallel with sleep spindles, ripple activity is suppressed during the hyperpolarized down-state and enhanced during the depolarized up-state. The temporal coupling between slow oscillations, spindles and ripples has been suggested to serve a hippocampo-neocortical dialogue underlying memory consolidation during sleep. Here, we examined whether a similar coupling exists between these oscillatory phenomena in humans. In sleep recordings from seven epileptic patients, scalp-recorded slow oscillations and spindles as well as parahippocampal ripples recorded from foramen ovale electrodes were identified by automatic algorithms. Additionally, ripple and spindle root mean square activity was determined for relevant frequency bands. Ripple density was higher during Non-REM than REM sleep (P < 0.001). Ripple activity distinctly decreased time-locked to slow oscillation negative half-waves in the three patients without temporal structural alterations (P < 0.001), whereas in the four patients with severe mesiotemporal structural alterations this coupling was obscure. Generally, in the patients ripple activity was increased before spindle peaks and distinctly decreased after the peak (P < 0.001). Ripples were consistently associated with interictal spikes suggesting that spike-ripple complexes represent an epileptic transformation of sharp wave-ripple complexes in the epileptic hippocampus. Our findings are consistent with the notion of a hippocampo-to-neocortical information transfer during sleep that is linked to coordinate ripple and spindle activity, and that in the intact temporal lobe is synchronized to cortical slow oscillations.

Twenty-four hours retention of visuospatial memory correlates with the number of parietal sleep spindles
Publication year: 2006
URL:
http://www.ncbi.nlm.nih.gov/pubmed/16714084
Abstract/Results: ABSTRACT:
Recent evidence suggests that the sleep-dependent consolidation of declarative memories relies on the non-rapid eye movement (NREM) rather than the rapid eye movement (REM) phase of sleep. Moreover, a few studies both at the cellular and the behavioural levels have suggested the involvement of sleep spindles, the most synchronous oscillatory waveforms during NREM sleep stage 2, in this process. Our previous study showed that overnight verbal memory retention correlates with the total number of sleep spindles in left frontocentral areas, while spindling in other regions did not correlate with mnemonic retention. In the present study, we show that retention of visuospatial memories over a 24-h period correlates with the total number of sleep spindles detected over parietal regions during the intervening night-time sleep. This result provides further evidence for the association between sleep spindle activity and declarative memory consolidation, and suggests that visuospatial and verbal memory retention differ in the topographic distribution of the NREM spindle activity with which they are associated.

Increased parahippocampal delta activity characterises virtual navigation and REM sleep in humans
Publication year: 2006

Abstract/Results: ABSTRACT:
Hippocampal theta or rhythmic slow activity (RSA) occurring during exploratory behaviours and rapid-eye-movement (REM) sleep is a characteristic and salient oscillatory rhythm in animals. By contrast, much controversy exists regarding the existence and the characteristics of this activity in humans. Some studies argued that human hippocampal theta activity appears in short and phasic bursts. On the contrary, earlier we showed that REM-dependent RSA recorded from the parahippocampal region is continuous like in animals but instead of the theta it falls in the delta frequency range. Here, we examined parahippocampal activity in 10 epilepsy patients implanted with foramen ovale electrodes while they were engaged in a virtual navigation task. Navigation was tested according to three conditions: an acquisition, a recall and a non-learning route-following condition. Recordings were also sampled from resting and REM sleep. For analyses, spectral power densities (SPD) were calculated for each 1 Hz wide frequency bin up to 10 Hz. During acquisition, SPD significantly increased in the 1 Hz, 2 Hz and the 3 Hz frequency bins when compared with resting. A similar but more robust increase was present in the 1 Hz, 2 Hz, 3 Hz, 4 Hz and 5 Hz frequency bins during REM sleep. Thus, increase was present in similar frequencies during the two conditions and these frequency ranges were below the traditional theta band. At the same time, other features of this activity, such as state-dependency and tonicity made this activity comparable to that seen in animals and suggest this activity to be the human analogue hippocampal theta in animals.

Abstract/Results: ABSTRACT:
Ripples are high-frequency oscillation bursts in the mammalian hippocampus mainly present during NREM sleep. In rodents they occur in association with sharp waves and are known to be grouped by the cortical slow oscillation such that their occurrence is maximal during the surface positive, up states. Ripples were also shown to be temporally linked to sleep spindles. Importantly, coordinated spindleripple events have been suggested to provide a framework for information transfer between the hippocampus and the neocortex underlying memory consolidation. Our aim was to examine whether ripples recorded via parahippocampal electrocorticography are also temporally linked with slow oscillations and sleep spindles in epileptic
humans. Whole-night recordings from seven epilepsy patients implanted with foramen ovale (FO) electrodes were analysed. Negative half waves of the slow oscillation and sleep spindles recorded on the scalp as well as ripples in FO recordings were detected by an automatic algorithm. Ripple activity was also measured as root mean square (RMS) of the 80–140 Hz activity. Compared to baseline both ripple measures showed a significant increase time-locked to sleep spindles. In the three patients without temporal structural alterations ripple activity decreased time-locked to slow oscillation negative half waves. In the four other patients exhibiting hippocampal sclerosis, modulation of ripple activity by the negative half waves was much less clear. Ripples significantly increased during NREM sleep and were consistently associated with interictal epileptic spikes. This suggests that ripple/spike complexes represent an epileptic exaggeration of ripple/sharp wave complexes in the human epileptic hippocampus. Whether ripples are epileptically transformed or not, the present data provide first evidence for a temporal coupling between hippocampal ripples and neocortical spindles in humans.

Abstract/Results: ABSTRACT:
Ripples are high-frequency oscillation bursts in the mammalian hippocampus mainly present during Non-
REM sleep. In rodents they occur in association with sharp waves and are grouped by the cortical slow oscillation such that, in parallel with sleep spindles, ripple activity is suppressed during the hyperpolarized down-state and enhanced during the depolarized up-state. The temporal coupling between these oscillations has been suggested to serve a hippocampo-neocortical dialogue underlying memory consolidation during sleep. Here we examined whether a similar coupling exists between these oscillatory phenomena in humans. We based our investigations on epilepsy patients undergoing presurgical evaluation implanted with foramen ovale electrodes. Recording with foramen ovale electrodes is a unique technique allowing parahippocampal electrocorticography in a semi-invasive way. In sleep recordings from seven epileptic patients, scalp-recorded slow oscillations and spindles as well as parahippocampal ripples recorded from foramen ovale electrodes were identified by automatic algorithms. Additionally, ripple and spindle root mean square activity was determined for relevant frequency bands. Ripple activity distinctly decreased time-locked to slow oscillation negative half-waves in the three patients without temporal structural alterations, whereas in the four patients with severe mesiotemporal structural alterations this coupling was obscure. Generally, in the patients ripple activity was increased before spindle peaks and distinctly decreased after the peak. Ripples were consistently associated with interictal spikes suggesting that spike/ripple complexes represent an epileptic transformation of sharp wave/ripple complexes in the epileptic hippocampus. Our findings are consistent with the notion of a hippocampo-to-neocortical information transfer during sleep that is linked to coordinate ripple and spindle activity, and that in the intact temporal lobe is synchronized to cortical slow oscillations.
