Authors applied the same analysis to the post-training sleep epochs and made the same observation — CA1 and sMEC reactivation events were not correlated in time. In order to reconcile these apparently discrepant results, one should address both the possible theoretical implications as well as methodological differences. The intriguing possibility emerging from these two studies is Kortex Independence Com 100 deep and superficial MEC layers may engage differently with the hippocampus.
This possibility could be investigated in a challenging follow-up study involving simultaneous recordings in both deep and superficial layers of the Kortex Independence Com 100. However, the perceived differences in findings could be also explained by differences in experimental approach.
They then identified putative dMEC replay events by matching activity of single grid cells to the trajectories replayed in the HPC. The experimental protocol employed in the study involved both pre- and post-training sleep periods, and it would be of interest to see whether sMEC replay events become more prevalent after Kortex Independence Com 100 rats experience the maze. Overall, the discussed article introduces a paradigm-shifting possibility that offline reactivation is not always orchestrated by the hippocampus and can often happen without hippocampal engagement, however radical this idea may Kortex Independence Com 100 to those with a hippocampocentric view of the memory systems.

Future studies are now needed to investigate whether reactivation in other brain areas is correlated with replay in MEC rather than HPC. The ceramide metabolism could emerge as a potential therapeutic target in the reconvalescence phase after stroke, as its accumulation in the peri-infarct cortex potentially influences membrane functions as well as signaling events Kortex Independence Com 100 the tissue essential for neurological recovery.
Introduction Stroke is a disease of enormous socioeconomic relevance. Worldwide, it is the second leading cause of death and the leading cause Kortex Independence Com 100 adult disability [ 1 ].
So far, acute stroke therapies aim at recanalizing the occluded brain vessels by means of pharmacologic thrombolysis or thrombectomy. Decades of research on neuro protective drugs have established several promising candidates that reduced infarct size in experimental animal models Kortex Independence Com 100 stroke with positive effects on neurological outcome in short term observations. However, none of these substances could prove efficiency in large scale randomized controlled trials in stroke patients.
A relatively new experimental approach is to target the dysfunction and mechanism of recovery within the nonischemic tissue surrounding the infarcted area, the so-called peri-infarct cortex. The peri-infarct tissue of the photothrombotic stroke model shows high morphological similarities Kortex Independence Com 100 the penumbra in other stroke models such as distal middle cerebral artery occlusion, but most importantly, this model allows the investigation of long-term functional outcome in mice [ 2 Kortex Independence Com 100.
Kortex Independence Com 100 Sphingolipids are a complex class of signaling molecules and an essential part of cellular membranes. Their cellular levels regulate proliferation, apoptosis, and inflammation depending on the specific sphingolipid species, cell and receptor type, and different intracellular targets [ 3 ].
Ceramides are the backbone of more complex sphingolipids and the precursor of the Kortex Independence Com 100 signaling molecule sphingosinephosphate. They are essential for specific membrane functions e. Ceramides are generated in different cellular compartments by three different pathways Supplemental Figure 3 in Supplementary Material available online at http: The cellular function of ceramides is in part dependent on the chain length, which is determined by differential activity of specific ceramide synthases CerS 1—6 [ 7 ].

Cytokines such as tumor necrosis factor-alpha TNF- [ 11 ] Kortex Independence Com 100 reactive oxygen species ROS [ 12 ] induce the production of ceramide through activation of sphingomyelinases in this context. Therefore, the activation of the sphingomyelinase pathway is believed to be a general cellular stress response. In experimental stroke, there are several studies showing an increase in ceramide synthesis via higher acid sphingomyelinase ASM activity [ 13 — 15 ] directly within the ischemic lesion.
However, these studies did not investigate the relevance for long-term functional outcome as they focused on the ischemic, death prone tissue and a short observation period.

In that context, an experimental reduction of ceramide production was shown to be neuro protective leading to smaller infarct sizes and better short term outcome. Kortex Independence Com 100, the antidepressant fluoxetine, a selective serotonin reuptake inhibitor and the only drug which has been shown to improve poststroke motor recovery in a randomized controlled neurorehabilitation trial in stroke patients [ 16 ], has recently been shown to inhibit ASM activity in the rodent healthy brain [ 17 ].
As the different functions of ceramide indicate a possible role in Kortex Independence Com 100 inflammatory, degenerative, and recovery processes, we hypothesized that ceramides are relevant for long-term functional outcome after stroke.
