Sentences with phrase «synaptic contacts»
"Synaptic contacts" refer to the connections between nerve cells, known as neurons, in the brain. These connections allow information to be transmitted from one neuron to another, which is essential for normal brain function and communication. Full definition
Glutamate receptors (pink spots) concentrate at sites of synaptic contact on a hippocampal neuron dendrite.

By using markers that could identify newly - formed brain cells, they found that running mice developed about twice as many new cells, and those cells had longer dendrites, compared to the sedentary mice, which facilitates the formation of new synaptic contacts between the nerve cells.
When new information needs processing, the nerve cells can develop new synaptic contacts with their neighbouring cells or strengthen existing synapses.
The team studied a protein in the brain called neural cell adhesion molecule 2, or NCAM2 — one of a family of molecules that physically connects the membranes of synapses and help stabilise these long lasting synaptic contacts between neurons.
According to Dr. Oh, these findings suggest a model in which GABA is the common molecule that sets the balance between inhibitory and excitatory synaptic contacts in early postnatal stages.
Once the elongating fibers have established the appropriate synaptic contacts with the target cells, the continued survival of the innervating cells in the ganglion appears to depend on the availability of NGF.
Here we develop a semi-automated pipeline using electron microscopy to reconstruct a connectome, containing 379 neurons and 8,637 chemical synaptic contacts, within the Drosophila optic medulla.
The human brain is a very spectacular electrochemical machine with billions of nerve cells and trillions of synaptic contact points.
Inducible expression of a mutated mitochondrial UNG1 DNA repair enzyme in forebrain neurons caused generation of apyrimidinic mDNA and neuronal impairment including reduced size of synaptic contacts (Mol Cell Mol 2010).
The number of neurons in each human brain is on the order of billions, and the synaptic contacts that the neurons make among themselves number in the trillions.
Neurons were detected using the pan neuronal marker TuJI (red) and the synaptic contact by alpha - Bungarotoxin (green).
