As “visual recognition memory” emerges in the visual cortex, one circuit of inhibitory neurons supplants another, and slower neural oscillations prevail.
The findings could lead to faster, more secure memory storage, in the form of antiferromagnetic bits.
Findings suggest this hippocampal circuit helps us to maintain our timeline of memories.
Astrocytes with the APOE4 gene variant show deficits of a key cellular function, but overexpressing the gene PICALM overcame the defect.
Modifications to chromosomes in “engram” neurons control the encoding and retrieval of memories.
Study also finds specific frequency bands of brain waves associated with encoding, or inhibiting encoding, of sensory information across the cortex.
New statistical model may help scientists understand how animals infer whether surroundings are novel or haven’t changed enough to be a new context.
The lateral septum encodes spatial information with a special emphasis on where the reward lies.
Neurons that store abstract representations of past experiences are activated when a new, similar event takes place.
The same neurons responsible for encoding reward also form new memories to suppress fearful ones.
