The hippocampus
Figure 1. Coronal slice through the transverse axis of the hippocampus. The black lines trace the classic ‘trisynaptic loop’. The red lines depict other important pathways in the hippocampus, including the direct projections from entorhinal cortex (EC) to all three CA fi elds, the feedback to the EC via the subiculum, the recurrent collateral circuitry of CA3, and the feedback projection from C...
متن کاملHippocampus: Remembering the Choices
The hippocampus is said to be involved in "navigation" and "memory" as if these were distinct functions. In this issue of Neuron, Singer et al. (2013) provide evidence that the hippocampus retrieves spatial sequences in support of memory, strengthening a convergence between the two perspectives on hippocampal function.
متن کاملRe-engineering the Hippocampus
As adult-generated neurons integrate into hippocampal circuits, they compete with mature neurons for inputs from the entorhinal cortex. By reducing spines on mature granule cells, McAvoy et al. (2016) find that new neurons integrate more efficiently, and this facilitates learning.
متن کاملOverworking the hippocampus
The postulated hippocampal comparator, like any other subsystem, must rely on "syntactic" patterns in its "input," and hence could not have the extraordinary powers Gray supposes. It may playa more modest role, but it is not the place "where it all comes together" for consciousness. Gray mistakenly thinks I have rejected the sort of theoretical enterprise he is undertaking, because, according t...
متن کاملHippocampus.
Damage to the hippocampus and related brain regions causes a profound amnesic syndrome, in which patients are unable to form new memories about their experiences and about facts about the world. A number of theories have been proposed to explain hippocampal function. The theories that are currently most influential propose that the hippocampus is the substrate of declarative or episodic memory ...
