A previously undescribed protein increases signals
transmitted by neurons by amplifying two major signaling pathways.
Not exact matches
Neuronal activity typically requires sensory input — for example, a taste or smell — that gets received
by neurons» dendrites and then
transmitted as an electrochemical message to other cells via long axons.
To
transmit electrical signals along a
neuron, a strong difference in charge between the interior and exterior of the cell is needed, which is created
by pumping positive ions into the cell.
They discovered that pheromones secreted
by the male mouse activate these
neurons which, in turn,
transmit this signal to another population of
neurons (gonadotropin - releasing hormone
neurons) to drive attraction to the opposite sex.
Action potentials can be created
by many types of cells, but are used most extensively
by the nervous system for communication between
neurons and to
transmit information from
neurons to other body tissues such as muscles and glands.
In the new study, the team focused on
neurons called amacrine cells and horizontal cells, which have a known role in «preprocessing» — or adjusting — electrical signals
transmitted to the brain from the photoreceptors after they have been stimulated
by light photons.
These antidepressants, which often have fewer side effects than others, prevent
transmitting neurons from quickly soaking serotonin back up that has not been absorbed
by receptors on other
neurons, thus giving the neurotransmitter more time in the synapse to exert an effect.
Previous research
by Lee's lab had shown that p75 is involved in a signaling pathway that regulates the development of sensory
neurons — cells which
transmit our sensation of pain, touch and muscle tension — in the dorsal root ganglia.
Members of the GDNF family support the survival of sensory
neurons that
transmit the pain signal and p75 enhances this survival - promoting effect
by interacting with Ret.
Nerve cells in the brain, or
neurons, are known to communicate among themselves
by transmitting electrical signals, aided
by chemical signaling at the synapses connecting the
neurons.
Chronic pain can be viewed as a learned memory: In the way that repetition of a piano piece enables you to learn it
by facilitating transmission of the appropriate signals through your
neurons, pain that persists can become chronic because your
neurons become more efficient at
transmitting pain signals.
Retinas are built of a stack of different types of
neurons, each connected
by synapses that
transmit signals from photoreceptors to the brain.
Neural signals are
transmitted within
neurons by changing calcium concentrations, so the researchers used this technique to measure the amount of calcium contained within the Purkinje cells in real time.
It is due to these proteins that the information arriving at a synapse can be
transmitted and then received
by the next
neuron.
The algorithms, which tell computers how to learn from data, are used in computer models called artificial neural networks — webs of interconnected virtual
neurons that
transmit signals to their neighbors
by switching on and off, or «firing.»
When these photoreceptors detect light, they send a signal to specialized
neurons in the retina called retinal ganglion cells, or RGCs, which then
transmit visual information to the brain
by firing electrical pulses along the optic nerve.
Neurons, or nerve cells, in the brain communicate with each other
by transmitting electric signals, or firing action potentials, through long processes named axons (which send out signals) and dendrites (which receive signals).
MS is a debilitating neurological disease caused
by the destruction of oligodendrocytes, cells that build the myelin sheaths that surround the signal
transmitting axons of
neurons.
In humans, deafness is most often caused
by damage to inner ear hair cells — so named because they sport hairlike cilia that bend when they encounter vibrations from sound waves — or
by damage to the
neurons that
transmit that information to the brain.
«Therefore, changes in the genes influence the brain's wiring
by altering the synapse and shaping how
neurons transmit signals to each other.»
The information gathered
by your senses is
transmitted by nerve cells, or
neurons, to specific brain regions where the signal is routed through circuits and sent downstream to areas that essentially translate the information into behavior and get you back on track.
Neurons communicate with each other
by transmitting signaling molecules.
Neurons transmit chemical signals in a fleeting «kiss - and - run» process, which in large part determines how quickly neurons can fire, according to new studies by Howard Hughes Medical Insti

Neurons: They
transmit information along the nervous system, connected
by synapses.
