The spontaneous replay of patterns of activity related to past experiences and memories is
a striking feature of brain activity, as is the coherent activation of sets of brain areas — …

Hippocampal activity patterns representing movement trajectories are reactivated in immobility
and sleep periods, a process associated with memory recall, consolidation, and decision …

Orientation in space is represented in specialized brain circuits. Persistent head direction
signals are transmitted from anterior thalamus to the presubiculum, but the identity of the …

Grid cells with their rigid hexagonal firing fields are thought to provide an invariant metric to
the hippocampal cognitive map, yet environmental geometrical features have recently been …

The hippocampus is thought to initiate systems-wide mnemonic processes through the
reactivation of previously acquired spatial and episodic memory traces, which can recruit the …

Unsigned Distance Fields (UDFs) can be used to represent non-watertight surfaces. However,
current approaches to converting them into explicit meshes tend to either be expensive or …

Rhythms with time scales of multiple cycles per second permeate the mammalian brain, yet
neuroscientists are not certain of their functional roles. One leading idea is that coherent …

Hippocampus–neocortex interactions during sleep are critical for memory processes:
Hippocampally initiated replay contributes to memory consolidation in the neocortex and …

One obstacle to understanding the exact processes unfolding inside the hippocampus is
that it is still difficult to clearly define what the hippocampus actually does, at the system level. …

Background Although the stomach is the most frequent site of intestinal lymphomas, few data
are available on both clinical endoscopic presentation of gastric lymphoma and possible …
