Neuronal activity regulates extracellular tau in vivo
Tau is primarily a cytoplasmic protein that stabilizes microtubules. However, it is also found in the extracellular space of the brain at appreciable concentrations. Although its presence there may be relevant to the intercellular spread of tau pathology, the cellular mechanisms regulating tau release into the extracellular space are not well understood. To test this in the context of neuronal ...
متن کاملHyperglycemia modulates extracellular amyloid-β concentrations and neuronal activity in vivo.
Epidemiological studies show that patients with type 2 diabetes (T2DM) and individuals with a diabetes-independent elevation in blood glucose have an increased risk for developing dementia, specifically dementia due to Alzheimer's disease (AD). These observations suggest that abnormal glucose metabolism likely plays a role in some aspects of AD pathogenesis, leading us to investigate the link b...
متن کاملNeuronal avalanches in spontaneous activity in vivo.
Many complex systems give rise to events that are clustered in space and time, thereby establishing a correlation structure that is governed by power law statistics. In the cortex, such clusters of activity, called "neuronal avalanches," were recently found in local field potentials (LFPs) of spontaneous activity in acute cortex slices, slice cultures, the developing cortex of the anesthetized ...
متن کاملIn Vivo Magnetic Recording of Neuronal Activity.
Neuronal activity generates ionic flows and thereby both magnetic fields and electric potential differences, i.e., voltages. Voltage measurements are widely used but suffer from isolating and smearing properties of tissue between source and sensor, are blind to ionic flow direction, and reflect the difference between two electrodes, complicating interpretation. Magnetic field measurements could...
متن کاملStriatal nitric oxide signaling regulates the neuronal activity of midbrain dopamine neurons in vivo.
A major component of the cortical regulation of the nigrostriatal dopamine (DA) system is known to occur via activation of striatal efferent systems projecting to the substantia nigra. The potential intermediary role of striatal nitric oxide synthase (NOS)-containing interneurons in modulating the efferent regulation of DA neuron activity was examined using single-unit recordings of DA neurons ...
