Sending Your Grandparents to University Increases Cognitive Reserve
Objective: Increasing an individual’s level of cognitive reserve (CR) has been suggested as a nonpharmacological approach to reducing the risk for Alzheimer’s disease. We examined changes in CR in older adults participating over 4 years in the Tasmanian Healthy Brain Project. Method: A sample of 459 healthy older adults between 50 and 79 years of age underwent a comprehensive annual assessment ...

The cochlear implant, a microelectrode array that directly stimulates the auditory nerve, has greatly benefited many individuals with profound deafness. Deaf patients without an intact auditory nerve may be helped by the next generation of auditory prostheses: surface or penetrating auditory brainstem implants that bypass the auditory nerve and directly stimulate auditory processing centers in ...

The cell membrane provides a physical barrier that separates the internal contents of a cell from the surrounding environment. This separation enables the generation of higher (or lower) concentrations of chemicals within the cell compared to the extracellular conditions. Furthermore, it enables the formation of electrochemical gradients across the cell membrane that can be used to drive biolog...

The Hebbian hypothesis of activity-dependent synaptic plasticity has gained much support from experimental studies of long-term potentiation and depression. Such studies have also uncovered complex patterns of competition among the synapses. Such eeects may be due to the neuron redistributing its limited synaptic resources as synaptic strengths change. In computational models this strategy is c...
