Sign in to download hi-res image Fig. 3.(A) Axial and (B) sagittal fGATIR 3T images. The hippocampal head (H) is located anterior to the plane of the interpeduncular cistern, whereas the tail (T) is posterior to the midbrain (M) and the body (B) is in between. The amygdala ...
Depending on localization error (how far the blue disk centre was from the true location of the hidden circle) and the cost of sampling, the score for each trial was calculated and provided as feedback at the end of the trial (equation in Fig. 1). The task thus imposed an economic ...
If the classification accuracy for object location increases and goes above chance level after learning, then it can be inferred that the objects acquired new neural representations in the brain based on their locations in the virtual building.

a, Coronal brain section showing location of cannula in the dorsal hippocampus (black arrow) together with position of guide cannula in overlying cortex. b, Coronal brain section showing spread of muscimol (red) after infusion into the hippocampus. Experiments were repeated in n = 3 rats with ...
Brain regions showing altered connectivity to left or right hippocampus in AD group after acupuncture comparing to before acupuncture.Zhiqun, WangPeipeng, LiangZhilian, ZhaoYing, HanHaiqing, SongJianyang, XuJie, LuKuncheng, Li
We provide evidence for a differential and dose-dependent regulation of the different brain-derived neurotrophic factor promoters in the hippocampus by afferents in the entorhinal cortex. Our finding of a graded regulation is in contrast to earlier evidence of an "all-or-none" type of regulation....
Full size image Given the higher fraction of cells with place fields and higher reliability in activity for Fos-high cells, we reasoned that these cells may constitute a subpopulation well suited for representing the mouse’s current location. We trained a naive Bayes’ decoder to predict the mo...
in rat hippocampus during global ischemia and reperfusion (IR). During IR, perfusate containing salicylic acid was collected and analyzed for non-enzymatic hydroxylation of salicylate to 2,3-DHBA. Since 21-aminosteroids can attenuate excitatory amino acid-mediated OH. production in the brain, we ...
The Nr4a subfamily,Nr4a1, Nr4a2, andNr4a3, serve as major regulators of gene expression in the hippocampus during memory consolidation59,60,72,73,81,82.Nr4a1andNr4a2are necessary for object location memory in the dorsal hippocampus, while onlyNr4a2is necessary for object recognition memory72....
The BBB model proposes that the hippocampus is needed to impose a location from which to retrieve and construct a coherent mental image of an environment. This mental image supports the online maintenance and manipulation of representations of the locations of objects and features in an environment....
