Geomagnetic visual prosthesis helps blind rats find their way
Article

Navigating a complex environment requires an egocentric representation: a neural signature of how you and your body relate to objects in your visual field. Part of the difficulty in exploring space for those without sight is the challenge of understanding how object positions relate to each other (allocentric representation) and to oneself (egocentric representation).

Article

Alzheimer’s disease (AD), a progressive and highly disruptive neurodegenerative condition, leads to a severe decrease in cognitive capabilities. Though the root cause of AD is unclear, it is known that increased levels of amyloid-β—a cleavage product of the amyloid precursor protein (APP)—are associated with development of the disease.

Cold-shock protein protects against neurodegeneration
Article

In the adult brain, communication between neurons is constantly remodeled by the elimination of old synapses and the formation of new ones; this turnover of synapses is called structural plasticity. Patients with neurodegenerative diseases such as Alzheimer’s disease have fewer synapses compared to normally aging adults, suggesting that their brains have decreased structural plasticity.
