... stimulating a normal, regular heartbeat, it uses high-frequency electricity to block the nerve impulses between the brain and the stomach and pancreas. A pacemaker continuously monitors the heart and ...
... , the retina's role in vision is to convert light into nerve impulses to the brain. The findings on retina self-repair ... to detect any regenerated inner retina nerve cells, except when the Müller glia ...
... that mammals can be stimulated to regrow inner nerve cells in their damaged retinas. Located in the back of the eye, the retina's role in vision is to convert light into nerve impulses to the brain.
... , it is the shape of the cochlea - the snail-shell-shaped organ in the inner ear that converts sound waves into nerve impulses that the brain deciphers - which proves to be surprisingly important...
... a role in the transport of oxygen to tissues and physiological activities such as the transmission of nerve impulses, and the beating of the heart. When things go awry with the nitric oxide system, ...
... more brain power, but that, during evolution, increasingly sophisticated molecular processing of nerve impulses allowed development of animals with more complex behaviours.
The study shows that two ...
... to the appendage, and the catheter is withdrawn.
Atrial fibrillation occurs when faulty nerve impulses cause the atria to beat erratically. Using traditional or minimally invasive operating ...
... channels – protein "tunnels" through brain cell membranes involved in the electrical conduction of nerve impulses.
The findings identify cellular events that may prompt migraines – specifically the ...
... sorts sodium ions to the outside of the cell and potassium ions to the inside. To transmit a nerve impulse, an electrochemical change ripples down the membrane in advance of the impulse, making it ...
... in the laboratory.
ALS is caused by the degeneration and death of motor neurons, the nerve cells which convey nerve impulses from the spinal cord to each of the body's muscles. The death of motor ...
Dr. Ritchie, a biophysicist at Yale, famously asked the Central Intelligence Agency to share with scientists its supply of the neurotoxin he was using in his studies.
... the number of inhibitory circuits, which actually increases the efficiency of transmission of excitatory nerve impulses in specific neurons, resulting in greater short-term and long-term plasticity ...
... regulate muscle contraction in the digestive tract. nNOS generates nitric oxide, which transmits nerve impulses in the digestive tract. Both are important for normal functioning but can be depleted ...
... specific molecules on nerve cells called nicotinic acetylcholine receptors, or nAChRs. When nerve cells communicate, nerve impulses jump chemically across gaps between cells called synapses by means ...
... in large storage pools called vesicles. However, gasses can't be stored; they diffuse. So every time there's a nerve impulse, an enzyme must be activated to make it," he says."
