Not exact matches

That's because the brain is involved, and — as an astoundingly complex network of 100 billion cells and their 100 trillion connections — the organ does not easily loose its secrets.

As recently as a few years back, researchers suggested there was a connection between brain cancer and cell - phone usagAs recently as a few years back, researchers suggested there was a connection between brain cancer and cell - phone usagas a few years back, researchers suggested there was a connection between brain cancer and cell - phone usage.

Using fluorescent antibodies designed specifically to light up the receptor in mice, the investigators observed it on vagus nerves, which serve as a main biochemical connection between airway cells and the brain.

GLP - 1 receptors are also found in the brain, and prior research has shown that activating them can boost the function of dopamine connections, act as an anti-inflammatory, improve energy production, and switch on cell survival signals.

Potentially explaining why even healthy brains don't function well with age, Salk researchers have discovered that genes that are switched on early in brain development to sever connections between neurons as the brain fine - tunes, are again activated in aging neuronal support cells called astrocytes.

And researchers must figure out how to build in some core features: the necessary blood vessels, immune - system cells called microglia and connections from other brain regions, such as the thalamus and cerebellum.

At a symposium at The American Society of Human Genetics here last month, they reported zooming in on the genes expressed in a single brain cell, as well as panning out to understand how genes foster connections among far - flung brain regions.

A renowned neuroscientist sees ideas of selection as describing the honing of connections among brain cells.

She hopes to pinpoint which genes are expressed in each cell type when brain cells make long distance connections, and to make similar maps in other primates to chart what changed as brains rewired over the course of evolution.

Researchers from Hiroki Taniguchi's lab at the Max Planck Florida Institute for Neuroscience (MPFI) published a study in eNeuro in May 2017 showing for the first time that a unique type of inhibitory interneuron called chandelier cells — which are implicated in several diseases affecting the brain such as schizophrenia and epilepsy — seem to develop their connections differently than other types of neurons.

As children, our brains produce too many connections between cells.

«I found this to be a shocking idea; that you could take, in that case, fetal cells and inject them into an organ as complicated as the brain and expect them to make connections,» he said.

The three scientists assembled small aggregates of nerve cells, known informally as «mini-brains,» and used them to study how specific groups of neurons in the brain find each other and establish connections.

The human brain contains as many as 100 billion neurons, most of which make hundreds to thousands of synaptic connections with specific target cells.

One of the precursors to Alzheimer's disease, which attacks the brain's nerve cells, is a loss of smell, so understanding this connection to olfactory nerve cells could perhaps serve as a diagnostic tool and perhaps unlock a deeper understanding of the degenerative disorder.

And within the brain the synapse maps are constantly being revised and rearranged as the cells make new connections and break others.

Describing the brain as a big circuit board in which each new experience creates a new circuit, Hopkins neuroscience professor Richard Huganir, Ph.D. says that he and his team found that during emotional peaks, the hormone norepinephrine dramatically sensitizes synapses - the site where nerve cells make an electro - chemical connection - to enhance the sculpting of a memory into the big board.

So it's not clear whether the new brain cells would have the same connections, or function the same as younger adult brain cells do, noted Dr. Ezriel Kornel.

One of Frankland's own studies in mice, for example, found that as new brain cells are formed in the hippocampus — a region of the brain associated with learning new things — those new connections overwrite old memories and make them harder to access.

Walnuts also contain polyphenolic compounds such as pedunculagin which can reduce the inflammatory load on brain cells, enhance neural connections, and increase neurogenesis (new neuron creation in the brain).
