Concepts encoded by concept neurons can be an animal, an article of clothing, a place, or a person. The concept can be evoked ...

How does one nerve cell transmit the nerve impulse to another cell? Electron microscopy and other methods show that it does so by means of special extensions that deliver a squirt of transmitter ...

also known as nerve impulses, which involve rapid changes in voltage across their membrane. When a neuron’s dendrite or cell body receives enough inputs from other neurons via chemical or electrical ...

Between the axon of a transmitting neuron and the dendrite of a receiving neuron is a gap called the synapse—the site at which signals are passed between the brain cells. The nervous system ...

An electrical impulse cannot directly cross the gap so a different mechanism has to be used. Between impulses the transmitter molecules are rapidly removed from the synaptic cleft to prevent ...

At excitatory synapses in the cerebral cortex, the most numerous synapses in our brain, the presynaptic nerve ending contains ... an electrical impulse from the cell soma, within one to a few ...

They placed central and peripheral nerve cells taken from rats together in ... these neurons make a connection called a synapse that transmits cold sensory information from the peripheral to ...

In recent years, many engineers have been trying to develop hardware components that could emulate the functions of various ...

"Our nerve cells are facing a similar dilemma: They have to supply their synapses, i.e., their contact points with other ...

Each nerve cell, or neuron, has three parts ... across a tiny space called a synapse, between the axons and dendrites of nearby neurons. Healing the human neurological system after injury ...

Microscopy images show fluorescently stained mouse brains expressing genes that cause Alzheimer’s disease. Compared with an Alzheimer’s-like brain (left), the more intense green color (right) ...

However, it was previously not understood how EPO regulates excitatory synapses involving interneurons. Interneurons are nerve cells of the central nervous system that interconnect other nerve cells.
