Other superconducting devices mimicking the human brain cells and transmission have been developed in the past, but efficient synapses
have been missing.
Maintaining brain cells and synapses
in good condition is critical, since mental performance and the ability of the brain to change in response to new information is totally reliant on the health of the brain's vast and complex network of synapses
5) Therefore, studies examining CNS synapse
formation were mainly conducted in a few specific types of synapses
, namely, those in which presynaptic and postsynaptic components are well-defined and both divergence and convergence of axonal projections are low, such as climbing fiber synapses
on cerebellar Purkinje cells.
A protein called Clq was packed around synapses
in the brains of young mice genetically engineered to show signs of Alzheimer's.
During normal brain development, a burst of synapse
formation occurs in infancy, particularly in the cortex, a region involved in autistic behaviors; pruning eliminates about half of these cortical synapses
by late adolescence.
In the new study, the team studied SIRP alpha function in the brain -- and started to understand its role in synapse
Sanes' team found a variety of age-related differences between the synapses
of the young and old mice.
The sticky synapse
; cell adhesion molecules and their role in synapse
formation and maintenance.
diameter (postsynaptic element) was measured from synapses
that were cut in cross sections from five animals in each of the three species.
The study, published in the Journal of Neuroscience showed that the release of zinc from synapses
is critical for Abeta to form oligomers and to aggregate.
People with more professional training and education have more synapses
in the prefrontal cortex of the brain, Illinois and Russian neuroscientists say.
In these studies, neuroscientists have documented that over our life spans the number of synapses
per unit area or unit volume of cortical tissue changes, as does the number of synapses
This year the team reported to the American Academy of Neurology that of the patients studied, 19 had in their blood autoantibodies directed against certain synapses
in their brain and spinal cord.
At that stage, the brain strengthens selected axon synapses
that correctly reach and enervate their target cells.
Objective: A fundamental question in neuroscience is how the biophysical properties of synapses
shape higher network computations.
