The idea of grandmother cells emerged from provocative studies showing that different neurons respond to different stimuli.

That led to scientists identifying different neurons that responded only when the test subject was shown pictures of a particular place.

«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.

At this point, this is all pure speculation because the detailed biophysical mechanisms and the effects of psilocybin on different neurons remain to be worked out.

So she's working to unravel how small genetic changes can impact how the brain is wired — specifically, how different neurons talk to each other — and in turn influence how we think and communicate.

However, in a new study from Karolinska Institutet published in the Nature Neuroscience, scientists show that the system comprises different neurons that regulate specific physiological functions, such as erectile muscle control.

Individual neural progenitor cells in culture produce different neuron types as time goes by, starting with the innermost cells (green) and followed by more superficial neurons (red).

The retina contains photoreceptors that convert light signals into electric signals, further transmitted to the brain by different neurons.

«We could then test drugs that affect different neuron types — such as those involved in Parkinson's disease — helping us to put drug development for neurodegenerative diseases on the fast track.»

The scientists can then turn different neurons in the striatum on and off to see how this alters the animal's behavior, revealing more about which cells do what in the brain.

Neuroscientists have been chorusing «cells that fire together, wire together» since the late 1990s, meaning that if you perform a task or recall some information that causes different neurons to fire in concert, it strengthens the connections between those cells.

The gate control theory of pain, put forward by Ron Melzack and Patrick Wall in 1962, is the idea that physical pain is not a direct result of activation of pain receptor neurons, but rather its perception is modulated by interaction between different neurons.

Such precision is critical in being able to study the hundreds of different neuron types, and understand higher brain functions such as thought, behavior, language, memory — or even mental disorders.

«We found that different neurons in the AIP were indeed selective for different grasps, but we also found activation for shoulder or hand movements, whether imagined or attempted, and for either side of the body,» Andersen says.

Previous tests have shown that specifc groups of neurons respond to different whole numbers, with the number one altering the firing patterns of different neurons than the number three.

Researchers long ago discovered that different neurons or nerve cells in the brain «selectively respond to sounds of a certain duration,» he says.

Electrophysiological experiments then led to further significant findings including the first demonstration that two different neurons that were electrically coupled could produce different neurotransmitters.

The axon is also known as a nerve fiber, and it functions to transmit nerve impulses away from the nerve cell body to different neurons, muscles and glands.

The findings, which are presented in the journal Neuron, show that the striatum acts as a sensory «hub» integrating various types of sensory information, with specialised functional roles for the different neuron types.

As this process — known to neuroscientists as Hebbian learning — occurs in multiple neighboring cells, it creates webs of connections between different neurons, encoding and linking information.
