Noisy brain activity contributes to aging-related navigation impairments

In younger adults, hippocampal activity decreases and acitivty in other navigational areas increases. The pattern is not seen in older adults. Credit: Diersch et al., JNeurosci 2021 Too much activity in the hippocampus may cause navigation impairments seen in aging adults, according to new research published in JNeurosci. Spatial navigation is one of the cognitive abilities that declines…
