Neurons that convert light into electrical impulses are called photoreceptor cells. These specialized cells are found in the retina of the eye and are responsible for detecting light and converting it into signals that the brain can interpret as visual information.
Contact between neurons is achieved through structures called synapses. At a synapse, the electrical signal (action potential) in the presynaptic neuron triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron, causing a change in its membrane potential and transmitting the signal.
An electrical charge that travels down the axon of a neuron is called an action potential. It is a rapid change in electrical voltage that allows for communication between neurons.
The basic signal in the nervous system is called an action potential. It is a rapid change in the surface charge of the cell membrane from a value around -70mV to 30 mV over several milliseconds controlled by the selective flow of sodium Na+, calcium Ca++ and potassium K+ ions (mostly).
The neuron is the functional portion of the central nervous system, carrying impulses to the designated location. Neurons also have the role of interpreting an impulse, and waiting for a response. Neurons fall under the category of sensory neurons, interneurons and motor neurons.
Neurons do not send impulses continuously; instead, they transmit signals in a discrete manner through action potentials. These action potentials occur when a neuron reaches a certain threshold of depolarization, leading to a rapid change in membrane potential. After firing, the neuron enters a refractory period during which it cannot fire another impulse, ensuring that signals are sent in a controlled and regulated fashion. This mechanism allows for precise communication between neurons and prevents continuous firing.

Neural impulses are generated when a neuron receives signals from other neurons or sensory receptors, causing a change in its membrane potential. This change in membrane potential triggers an action potential, a rapid electrical signal that travels down the axon of the neuron. This action potential then triggers the release of neurotransmitters at the synapse, allowing the signal to be passed on to other neurons.

In the eyes, light energy is converted into electrical signals by photoreceptor cells (rods and cones) in the retina. These electrical signals are then transferred to the brain through the optic nerve, where they are interpreted as visual information.
Action potential is the term for an electrical change in the neuronal membrane transmitted along an axon. The axon is part of a nerve cell that conducts impulses.
The electrical message that travels along a neuron is called an action potential. It is a brief change in electrical voltage that travels down the length of the neuron, allowing for communication between neurons and the transmission of signals throughout the nervous system.
Your brain has about 100 billion neurons, all of which are interneurons. Each of these neurons may receive up to 10,000 messages from other neurons and may send messages to about 1,000 more. Every day, billions of nerve impulses travel through your nervous system from neuron to other neurons or body structures. The place where a neuron transfers an impulse to another structure is called a synapse. At the axon tips, electrical signals carried through the neuron change into a chemical form. This change allows the message to cross the gap. The message then continues in electrical from through the next neuron.

To create movement and simple bodly functions the neurons in our bodies need to relay messages to one another by electrical impulses. When someone has ms the body begins to destroy what is called myelin sheaths and the cells that produce myelin. The sheaths are then replaced by hard tissue which don't allow the electrical impulses to pass throu. Which can cause mild to sever muscle weakness abnormal sensations such as numbness or tingling over any part of the body, vision change, loss of coordination, tremors, paralysis, poor posture and bowel and bladder dysfunction. All depending on how sever the case is.
The small change in the charge across a neuron's membrane is known as the action potential. It is a brief electrical impulse that travels along the neuron's membrane, allowing for the transmission of signals between neurons.
A momentary change in electrical potential on the surface of a cell, especially of a nerve or muscle cell, that occurs when it is stimulated, resulting in the transmission of an electrical impulse. &/or "nerve impulses" or "spikes".
