The eventual goal is to gain a better understanding of how signaling between different types of neurons controls memory and cognition.

The transmission of neural impulses between the touch - sensitive neurons in the skin and the spinal cord neurons that relay touch signals to the brain was also abnormal.

The authors suggest that the intricate balance between the signaling of neurons in these three brain regions may be crucial for normal social behavior in humans, and that disruption may contribute to various psychiatric conditions, including autistic spectrum disorders.

After the associations between smell and place were well established, the researchers could see a pattern of brain wave activity (the electrical signal from a large number of neurons) during retrieval.

For this, electrical signals fire between neurons connected by «axons» — thread - like extensions of their outer surfaces which can be viewed as the «wire» in the electric circuit.

Specifically, the bipolar neurons expressed more genes for membrane receptors and ion channels than non-bipolar cells, particularly those receptors and channels involved in the sending and receiving of calcium signals between cells.

According to Cheyette, this is some of the strongest evidence to date that WNT signaling could play a key role in driving psychiatric disease, and that it works through changes in synaptic communication between neurons.

In the absence of that protein, other proteins involved in transmitting signals between neurons in the brain are overproduced, notably mGluR5, a receptor for the neurotransmitter glutamate.

Pollard thinks this is probably a sign of inhibitory signalling between groups of neurons as the brain prepares to shut down.

In areas of the brain previously linked to IQ, the star percussionists also had more white matter — the fatty material that sheathes connections between neurons and boosts signal speed — indicating a larger amount of neural hookups there.

«Our results show we can detect a specific pattern of activity between neurons in the brain, recording instantaneous exchanges between them as persistent signals that can later be visualized under a microscope,» Gallio said.

The design was specific to that of a biological synapse — a small gap that exists between adjoining neurons over which chemical and electrical signals are passed.

Forward - looking studies are examining other possible information couriers: glial cells (poorly understood brain cells that are 10 times as common as neurons), other kinds of signaling mechanisms between cells (such as newly discovered gases and peptides), and the biochemical cascades that take place inside cells.

«So we tested the signaling between different neurons in fragile X mice, and indeed found there was abnormally high firing of action potentials — the signals between neurons — and also abnormally high synchrony; that is, too many neurons fired together.

One idea is that they reproduce the behaviour of synapses, the conducting gaps that ferry electronic signals between neurons.

This was found to interfere with the same mechanism, essentially by impairing the ability of alpha - synuclein to regulate the flow of synaptic vesicles, and hence compromising the signalling between neurons.

Here, we first demonstrated that Acks signals were detected in the MBs, especially in the Class II KCs of workers at 30 or 60 min after the bee ball formation, and neurons located in a restricted area between the DLs and the OLs of workers at 60 min whereas they were scarcely detected at 0 min (Figure 4, Figure S3, and Figure S4), strongly suggesting that these neurons are highly activated in the brains of workers involved in forming the hot defensive bee ball.

Acks signals were also detected in some neurons whose somata formed a cluster in a restricted region between the DLs and the lobula of the OLs (Figure 5J).
