Axon myelination is significantly disrupted in patients with Alzheimer's disease. Researchers also found brain cells of men and women vary significantly in how their genes respond to the neurodegenerative disease.
Researchers propose a new theory of memory formation, reporting memory storage does not rely on the strengthening of connection between memory cells, but on the pattern of connections that form within the first few minutes of an event.
A new neuron labeling technique allows researchers to obtain a snapshot of their activity at any moment in time. The new approach could provide new insights into neural functioning by offering better precision than current, more long term, labeling techniques.
