A New Neural-Optic System Can Manipulate Memories

A new neuro-optics technique can manipulate memory consolidation in mouse models by hindering long-term potentiation. Researchers say eliminating local LTP in the hippocampus erased memories. The method could be used to isolate memory formation at the cellular level.

Oxytocin Could Be Used to Treat Cognitive Disorders Like Alzheimer’s

Oxytocin, the so-called "love hormone," could help to treat cognitive disorders, including Alzheimer's disease. Researchers demonstrated oxytocin reversed the effects of amyloid-beta on hippocampal LTP in mice. The findings suggest oxytocin could be used as a therapeutic for the treatment of Alzheimer's disease and other dementias.

Fundamental insight into how memory changes with age

New memories are laid down via different mechanisms in older mice compared to younger mice. Additionally, synaptic changes linked to new memory formation were harder to modify in older mice.

Lack of oxygen doesn’t kill infant brain cells, as previously thought

A lack of oxygen as a result of preterm birth does not cause hippocampal neurons to die but does impair hippocampal development. Hypoxia causes hippocampal cells to fail to mature normally, causing a reduction in long-term potentiation and impaired learning.

Quick thinking? It’s all down to timing

A pairing of presynaptic and postsynaptic activity in a population of hippocampal neurons can reduce the required number of synaptic plasticity evoking events. When spikes occur within ten milliseconds of each other, synapses strengthen for up to four hours.

Estrogen Made by Neurons Important to Memory Making

Researchers report estrogen may play a significant role in synaptic plasticity and memory formation. The study reports mice whose neurons did not produce estrogen have impairments in spatial reference memories, recognition and contextual fear memories. Restoring estrogen levels assisted in reversing the memory impairments, the study revealed.
