Why Are Memories Attached to Emotions so Strong?

Hippocampal neurons that respond to fearful stimuli relay that information to the amygdala. These neurons synchronize when memories of the stimuli are later recalled. The synchrony is critical to establish fear memories and the greater the synchrony, the stronger the memory becomes.

To Let Neurons Talk, Immune Cells Clear Paths Through Brain’s ‘Scaffolding’

Dropping the level of the IL-33 immune molecule increased the number of synapses in the brain. In older mice, ramping up IL-33 helped push the number of new synapses toward a more youthful state.

Adult-born neurons grow more than their infancy-born counterparts

Neurons created as a result of adult neurogenesis mature for longer and grow larger than those created during infancy. Findings suggest adult-born neurons may have a more powerful function than those created during infancy and may play a critical role in neuroplasticity.

Noise-inducing neurons shut down memories in Alzheimer’s

In mouse models of Alzheimer's disease, active neurons still encode memory, and a group of active neurons encodes novel environmental information. The signal of the novelty containing neurons causes a superimposition disturbing the signal of memory encoding neurons.
