One study concluded that magnesium threonate increases the number of
synaptic connections between brain cells and boosts the density of synapses (30).
To examine this hypothesis we will identify the molecular changes to astrocytes during the aging process and then determine how these changes in aging affect
the synaptic connections between neurons.
This will allow for the capture of all
the synaptic connections between individual neurons at small targeted regions guided by the X-ray microtomography.
Learning and memory have been closely linked to strengthening of
synaptic connections between neurons (i.e., synaptic plasticity) within the dentate gyrus (DG)- CA3 - CA1 trisynaptic circuit of the
The finding, published online today in Science, adds to recent evidence that defects in
the synaptic connections between neurons can contribute to autism and related conditions.
Feng studies proteins that form
the synaptic connections between neurons, and his original goal was simply to see whether defects in such proteins could cause abnormal behavior.
A new in vitro model Scientists developed a new research tool for this study that enabled them to monitor the spread of Tau aggregates whilst changing
the synaptic connections between brain cells.
A form of learning in the marine mollusk Aplysia, long - term sensitization of the gill - and siphon - withdrawal reflex, results in the formation of new
synaptic connections between the presynaptic siphon sensory neurons and their target cells.
After all, each brain is unique, and each brain keeps changing in response to new experiences, forming new
synaptic connections between neurons and even — contrary to received wisdom a decade ago — growing new neurons.
Somehow the rules governing
synaptic connections between cells enable such «local» activity to modify the «global» neural circuitry that carries out the brain's many functions.
Over-activation of the D2 class of dopamine receptors led to suppression of the function of NMDA receptors, which are activated by the neurotransmitter glutamate, at
the synaptic connection between hippocampus and prefrontal cortex.

Shatz hypothesized that MHCI molecules might function as a kind of «
synaptic glue,» stabilizing contacts
between neurons once appropriate
connections had been established.
Moser demonstrated a number of changes in the strength of
connections between nerve cells — a phenomenon called
synaptic plasticity — in the hippocampus as rats stored information in their long - term memory.
At the cellular level, learning and memory require continuous readjustment of the strength of
synaptic junctions — the functional
connections between nerve cells.
After conducting studies in both humans and mice, the researchers said this new schizophrenia risk gene, called C4, appears to be involved in eliminating the
connections between neurons — a process called «
synaptic pruning,» which, in humans, happens naturally in the teen years.
When the researchers modeled the effects in mice, they found it strengthened the
connections between neurons that make learning possible — what is known as
synaptic plasticity — by increasing the action of a cell receptor critical to forming memories.
Because subunit composition can influence the docking
between hemichannels [14], it might be possible to pattern
synaptic connections through selective expression of innexins, of which 25 exist in C. elegans (reviewed in [1]-RRB-.
These studies reveal for the first time specific functional
connections between subsets of KCs and particular MBONs and establish the identity of
synaptic microcircuits underlying transmission of homeostatic sleep signals in the MB.
