"Electrical recordings" refers to the process of capturing and storing sounds using electronic devices. It involves converting sound waves into electrical signals, which can be saved and played back later.
Full definition
From studies of
electrical recordings of the rat hippocampus (an area of the brain associated with memory formation and storage), made while the rats were awake and learning a maze, Wilson and Louie found that some electrical patterns were quite specific and identifiable, depending on what the rat was doing.
One clue came from dual
electrical recordings showing that amacrine cells were capable of delivering an inhibitory signal to the «null direction» side of a retinal ganglion cell by releasing the neurotransmitter GABA.
The hair cells formed normal bundles (see images) that responded to sound waves and signaled the brain, as measured
by electrical recordings.
As they scrutinized the magnified slices of brain taken from their coked - up mice, Malenka and his colleagues collected the
minute electrical recordings that documented the response of one neuron to the firing of its neighbor.
Sitting at his computer in shorts and flip - flops, Raichlen pulled up Jeff's data: a rainbow - colored series of 16
synchronized electrical recordings from all the sensors.
When scientists removed or inactivated this same part of the brain in dogs, they observed that the dogs began to move around, even
though electrical recordings of the dogs» brains indicated that they were still fast asleep.
Using these
direct electrical recordings, the team was able to test the level of high frequency neuronal activity (a marker of neurons firing) in this region, a very precise measure which captures activity tied to cognition processes lasting mere hundreds of milliseconds.
We will make
precise electrical recordings of hundreds of neurons from many brain areas and use sophisticated microscopes to directly observe the brain in action.
«We're the first to develop something that enables
simultaneous electrical recording and optical stimulation in the spinal cords of freely moving mice,» said the paper's lead author, CSNE member and MIT graduate student, Chi (Alice) Lu in MIT News.
Brain imaging and
electrical recordings of brain activity (EEG) showed changes that likely account for his improvement, scientists led by Angela Sirigu of France's National Center for Scientific Research reported in Current Biology.
Electrical recordings showed that during low frequency stimulation of the central thalamus, zona incerta neurons fired in a spindle pattern that often occurs during sleep.
Electrical stimulation of the medial amygdaloid nucleus (AME) produces a behavioral state in male rats that resembles the postejaculatory interval, but
electrical recording from cells in the AME
Twenty years of
electrical recording in anesthetized laboratory animals provided ample evidence that many cortical cells, particularly in primary sensory cortical regions, continue to respond selectively during anesthesia.
The faces retained their identity even though functional brain imaging and
electrical recordings had pinpointed both left and right FFA circuits as responding more to faces over nonfaces.
Electrical recordings of signals transmitted from the hippocampus suggested that the animals had developed place cells — cells that are believed to convey a sense of location — and that these cells were firing when an animal passed through a familiar place.
One involved studies of
electrical recordings and brain lesions in monkeys.
Electrical recordings from the retinas of the engineered mice indicated that the added photopigment had enabled their color - sensing cone cells to respond to long wavelength red light, which normal mice can't see.
But while microscopy and
electrical recording could provide a broad picture of the structure and timing of neurotransmitter release, no one knew how vesicles reached the pre-synaptic membrane, or the nature of the invisible «threads» that pulled the two together, causing them to fuse and form the opening, or fusion pore.
This generally involves x-rays,
electrical recording of the heart (ECG) and ultrasound examination (echocardiography).
